Proportionality in the Conduct of Hostilities: The Incidental Harm Side of the Assessment

10 December 2018

Clarification of international humanitarian law is important in ensuring compliance with the rule of proportionality, but a culture of compliance within armed forces and groups is also crucial.

Summary

  • Military operations are taking place with increasing frequency in densely populated areas. Such operations result in loss of life and harm to civilians, as well as damage to civilian objects, (including infrastructure providing essential services). In order to protect civilians, it is imperative that armed forces and groups comply with the rules of international humanitarian law on the conduct of hostilities, including the rule of proportionality.
  • The rule of proportionality prohibits attacks which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects or a combination thereof, which would be excessive in relation to the concrete and direct military advantage anticipated. This research paper analyses the key steps that belligerents must take to give effect to the rule, with a particular focus on one side of proportionality assessments – the expected incidental harm.
  • Those undertaking proportionality assessments before or during an attack must consider whether the expected harm will be caused by the attack, and whether that harm could be expected (that is, was it reasonably foreseeable).
  • For the purpose of proportionality assessments, injury to civilians includes disease, and there is no reason in principle to exclude mental harm, even though it is currently challenging to identify and quantify it. Damage to civilian objects includes damage to elements of the natural environment.
  • Once the incidental harm to be considered has been identified, a value or weight must be assigned to it. This is then balanced against the value or weight of the military advantage anticipated from the attack to determine whether the harm would be excessive.
  • In the determination of whether the expected incidental harm would be excessive compared to the anticipated military advantage, ‘excessive’ is a wide but not indeterminate standard.
  • Belligerents should develop methodologies so that those planning and deciding attacks are provided with all necessary information on expected incidental harm, and to assist them in assigning weight to the incidental harm to be considered.
  • If it becomes apparent that the rule of proportionality will be contravened, the attack in question must be cancelled or suspended.
  • Clarification of the law is important in ensuring compliance with the rule of proportionality, but a culture of compliance within armed forces and groups, inculcated by their leaders, is also crucial.

Human Rights Impact Assessment of Trade Agreements

Research Event

26 February 2019 - 6:00pm to 7:30pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

James Harrison, Reader and Associate Professor, University of Warwick School of Law
Richard James, Evaluation Co-ordinator, Directorate-General for Trade European Commission
Jennifer Zerk, Associate Fellow, International Law Programme, Chatham House
Chair: Andrea Shemberg, Chair, Global Business Initiative on Human Rights

The idea that trade agreements should be subject to human rights impact assessment has been gathering momentum in recent years. This idea springs from concern – particularly on the part of trade unions and civil society organizations – that states are not presently doing enough to anticipate and address the human rights-related issues that arise from their trading arrangements with other countries.

This meeting will coincide with the launch of a research paper on human rights impact assessment by Dr Jennifer Zerk. It will bring together experts from law, trade policy, human rights impact assessment practice and civil society to take stock of progress so far and consider the future prospects for human rights impact assessment as a risk-analysis and policymaking tool in the trade context.  

The meeting will explore the key risks and benefits of the human rights impact assessment of trade agreements. What legal, political and practical challenges have been encountered so far? In what ways could communication, stakeholder consultation and follow-up of findings be improved? And what is needed to build political and stakeholder support for these kinds of processes?  

This meeting will be followed by a reception.

Certain ortho-hydroxylated brominated ethers are promiscuous kinase inhibitors that impair neuronal signaling and neurodevelopmental processes [Cell Biology]

The developing nervous system is remarkably sensitive to environmental signals, including disruptive toxins, such as polybrominated diphenyl ethers (PBDEs). PBDEs are an environmentally pervasive class of brominated flame retardants whose neurodevelopmental toxicity mechanisms remain largely unclear. Using dissociated cortical neurons from embryonic Rattus norvegicus, we found here that chronic exposure to 6-OH–BDE-47, one of the most prevalent hydroxylated PBDE metabolites, suppresses both spontaneous and evoked neuronal electrical activity. On the basis of our previous work on mitogen-activated protein kinase (MAPK)/extracellular signal-related kinase (ERK) (MEK) biology and our observation that 6-OH–BDE-47 is structurally similar to kinase inhibitors, we hypothesized that certain hydroxylated PBDEs mediate neurotoxicity, at least in part, by impairing the MEK–ERK axis of MAPK signal transduction. We tested this hypothesis on three experimental platforms: 1) in silico, where modeling ligand–protein docking suggested that 6-OH–BDE-47 is a promiscuous ATP-competitive kinase inhibitor; 2) in vitro in dissociated neurons, where 6-OH–BDE-47 and another specific hydroxylated BDE metabolite similarly impaired phosphorylation of MEK/ERK1/2 and activity-induced transcription of a neuronal immediate early gene; and 3) in vivo in Drosophila melanogaster, where developmental exposures to 6-OH–BDE-47 and a MAPK inhibitor resulted in offspring displaying similarly increased frequency of mushroom-body β–lobe midline crossing, a metric of axonal guidance. Taken together, our results support that certain ortho-hydroxylated PBDE metabolites are promiscuous kinase inhibitors and can cause disruptions of critical neurodevelopmental processes, including neuronal electrical activity, pre-synaptic functions, MEK–ERK signaling, and axonal guidance.

The Future of EU–US Cooperation in Space Traffic Management and Space Situational Awareness

29 August 2019

As more space activities develop, there is an increasing requirement for comprehensive space situational awareness (SSA). This paper provides an overview of the current landscape in SSA and space traffic management as well as possible scenarios for EU–US cooperation in this area.

Summary

  • Space situational awareness (SSA) and space traffic management (STM) are essential for sustainable near-Earth orbit. International cooperation in SSA and STM is vital with the growing number of satellite operators and the increasingly complex space environment.
  • The various definitions of SSA and STM are ambiguous. Understanding the activities that fall under each term can better assist in finding areas for cooperation and collaboration.
  • SSA has historically been a military activity, leading to an incomplete public catalogue of its use and barriers to sharing information with other states and the commercial sector. The rise in private space actors has increased the number of commercial STM providers and, with plans in the US to move responsibility for STM to civilian control, there will likely be more opportunities for international collaboration, particularly through the EU Space Surveillance and Tracking (SST) programme.
  • Individual EU member states possess developed STM capabilities, but overall these are still some way behind those of allies such as the US. Further investment in STM infrastructure and programmes is required for the EU and individual European states to be an essential partner to the US and add value to the global effort.
  • There are worldwide challenges, both political and technical, to providing STM coverage, which may lead to a lack of collaboration and gaps in understanding of activities in orbit. Existing sensors have limitations in terms of the size of objects that can be detected and the precision with which their movements can be predicted. These capability gaps represent opportunities for the EU to contribute.
  • The EU can build on its tradition of support for openness and civil society by creating a system that fosters an environment of cooperation and collaboration involving industry, commercial STM providers and the wider international community.
  • Although collaboration in STM is vital, the EU should also aim to tackle issues within the wider definition of SSA including space weather, intelligence and the security of ground stations.
  • The EU is well placed to become a global leader in SSA and STM. However, it needs to take into consideration the current political and technical landscape when making decisions regarding investment in capabilities and the pursuit of international partnerships.

The Commonwealth Cyber Declaration: Achievements and Way Forward

Invitation Only Research Event

4 February 2020 - 9:15am to 5:30pm

Chatham House, London

In April 2018, the Commonwealth Heads of Government Meeting (CHOGM), held in London, saw the creation and the adoption of the Commonwealth Cyber Declaration. The declaration outlines the framework for a concerted effort to advance cybersecurity practices to promote a safe and prosperous cyberspace for Commonwealth citizens, businesses and societies. 

The conference will aim to provide an overview on the progress made on cybersecurity in the Commonwealth since the declaration was announced in 2018. In addition, it will examine future challenges and potential solutions going forward.

This conference is part of the International Security Programme's project on Implementing the Commonwealth Cybersecurity Agenda and will convene a range of senior Commonwealth representatives as well as a selection of civil society and industry stakeholders. This project aims to develop a pan-Commonwealth platform to take the Commonwealth Cyber Declaration forward by means of a holistic, inclusive and representative approach.

Please see below meeting summaries from previous events on Cybersecurity in the Commonwealth:

Nuclear Weapons: Innovative Approaches for the Complex International Security Environment

This programme of work addresses the conundrum of nuclear weapons as a wicked problem in a complex adaptive system.

Understanding the complexity and the wickedness of the situation allows analysts and strategic planners to approach these complex and intractable issues in new and transformative ways – with a better chance of coping or succeeding and reducing the divisions between experts.

Using complexity theory, a complex adaptive system representing the international system and its interaction with the environment can be represented through an interactive visualization tool that will aid thought processes and policy decision-making. 

Until recently, analysts did not have the tools to be able to create models that could represent the complexity of the international system and the role that nuclear weapons play. Now that these tools are available, analysts should use them to enable decision-makers to gain insights into the range of possible outcomes from a set of possible actions.

This programme builds on work by Chatham House on cyber security and artificial intelligence (AI) in the nuclear/strategic realms.

In order to approach nuclear weapons as wicked problems in a complex adaptive system from different and sometimes competing perspectives, the programme of work involves the wider community of specialists who do not agree on what constitutes the problems of nuclear weapons nor on what are the desired solutions.

Different theories of deterrence, restraint and disarmament are tested. The initiative is international and inclusive, paying attention to gender, age and other aspects of diversity, and the network of MacArthur Grantees are given the opportunity to participate in the research, including in the writing of research papers, so that the complexity modelling can be tested against a wide range of approaches and hypotheses.

In addition, a Senior Reference Group will work alongside the programme, challenging its outcome and findings, and evaluating and guiding the direction of the research.

This project is supported by the MacArthur Foundation.

Libya's third bout of civil war in a decade began when Khalifa Haftar's Libyan Arab Armed Forces (LAAF) launched an offensive on Tripoli in April 2019. Since then, a growing number of foreign states have intervened ever more deeply in the conflict. Warring Libyan armed factions, broadly aligned with either the internationally recognized Government of National Accord or the LAAF, have become increasingly reliant on foreign support to prosecute their war effort.  

Against this backdrop, the panellists will reflect on the forces that have shaped Libya’s trajectory since 2011. As the prospects for international mediation remain bleak, what motivations and grievances are driving the country’s warring parties? How can this war be explained beyond a scramble for the control of Libya’s oil wealth? And are Libyans at risk of being mere pawns in a proxy war?

POSTPONED: The Development of Libyan Armed Groups since 2014: Community Dynamics and Economic Interests

Since the overthrow of the regime of Muammar Gaddafi in 2011, Libya’s multitude of armed groups have followed a range of paths. While many of these have gradually demobilized, others have remained active, and others have expanded their influence. In the west and south of the country,  armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks.

In the east, the Libyan Arab Armed Forces projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will need to address the fears, grievances and desires of the surrounding communities, even while the development of armed groups’ capacities dilutes their accountability to those communities.

This roundtable will discuss the findings of a forthcoming Chatham House research paper, ‘The Development of Libyan Armed Groups Since 2014: Community Dynamics and Economic Interests’, which presents insights from over 200 interviews of armed actors and members of local communities and posits how international policymakers might seek to curtail the continued expansion of the conflict economy.

Russia’s Middle East policy is driven by a complex mixture of traditional factors (such as the ongoing confrontation with the West) and new trends. The Kremlin is keen to maintain its position as an influential external broker. However, it is not confident Russia would be able to respond effectively if forced into a reactive mode by other regional players. The Kremlin therefore seeks to retain initiative and shape the agenda according to its needs and resources. This makes prediction of Moscow’s next moves in the region a challenging, but not impossible, task.

Nikolay Kozhanov will offer remarks on the changes that have taken place in Russia’s strategy since the publication of his research paper Russian Policy Across the Middle East: Motivations and Methods (2018).

Summary

  • Libya’s multitude of armed groups have followed a range of paths since the emergence of a national governance split in 2014. Many have gradually demobilized, others have remained active, and others have expanded their influence. However, the evolution of the Libyan security sector in this period remains relatively understudied. Prior to 2011, Libya’s internal sovereignty – including the monopoly on force and sole agency in international relations – had been personally vested in the figure of Muammar Gaddafi. After his death, these elements of sovereignty reverted to local communities, which created armed organizations to fill that central gap. National military and intelligence institutions that were intended to protect the Libyan state have remained weak, with their coherence undermined further by the post-2014 governance crisis and ongoing conflict. As a result, the most effective armed groups have remained localized in nature; the exception is the Libyan Arab Armed Forces (LAAF), which has combined and amalgamated locally legitimate forces under a central command.
  • In the west and south of the country, the result of these trends resembles a kind of inversion of security sector reform (SSR) and disarmament, demobilization and reintegration (DDR): the armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks; and have continued to arm, mobilize and integrate themselves into the state’s security apparatus without becoming subservient to it. In the eastern region, the LAAF projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. The LAAF has co-opted social organizations to dominate political and economic decision-making.
  • The LAAF has established a monopoly over the control of heavy weapons and the flow of arms in eastern Libya, and has built alliances with armed groups in the east. Armed groups in the south have been persuaded to join the LAAF’s newly established command structure. The LAAF’s offensive on the capital, which started in April 2019, represents a serious challenge to armed groups aligned with the Tripoli-based Government of National Accord (GNA). The fallout from the war will be a challenge to the GNA or any future government, as groups taking part in the war will expect to be rewarded. SSR is thus crucial in the short term: if the GNA offers financial and technical expertise and resources, plus legal cover, to armed groups under its leadership, it will increase the incentive for armed groups to be receptive to its plans for reform.
  • Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will necessarily rely on addressing the fears, grievances and desires of the surrounding communities. Yet the development of armed groups’ capacities, along with their increasing access to autonomous means of generating revenue, has steadily diluted their accountability to local communities. This process is likely to be accelerated by the ongoing violence around Tripoli.
  • Communities’ relationship to armed groups varies across different areas of the country, reflecting the social, political, economic and security environment:
  • Despite their clear preference for a more formal, state-controlled security sector, Tripoli’s residents broadly accept the need for    the presence of armed groups to provide security. The known engagement of the capital’s four main armed groups in criminal activity is a trade-off that many residents seem able to tolerate, providing that overt violence remains low. Nonetheless, there is a widespread view that the greed of Tripoli’s armed groups has played a role in stoking the current conflict.
  • In the east, many residents appear to accept (or even welcome) the LAAF’s expansion beyond the security realm, provided that it undertakes these roles effectively. That said, such is the extent of LAAF control that opposition to the alliance comes at a high price.
  • In the south, armed groups draw heavily on social legitimacy, acting as guardians of tribal zones of influence and defenders of their respective communities against outside threats, while also at times stoking local conflicts. Social protections continue to hold sway, meaning that accountability within communities is also limited.
  • To varying extents since 2014, Libya’s armed groups have developed networks that enmesh political and business stakeholders in revenue-generation models:
  • Armed groups in Tripoli have compensated for reduced financial receipts from state budgets by cultivating unofficial and illicit sources of income. They have also focused on infiltrating state institutions to ensure access to state budgets and contracts dispersed in the capital.
  • In the east of the country, the LAAF has developed a long-term strategy to dominate the security, political and economic spheres through the establishment of a quasi-legal basis for receiving funds from Libya’s rival state authorities. It has supplemented this with extensive intervention in the private sector. External patronage supports military operations, but also helps to keep this financial system, based on unsecured debt, afloat.
  • In the south, limited access to funds from the central state has spurred armed groups to become actively involved in the economy. This has translated into the taxation of movement and the imposition of protection fees, particularly on informal (and often illicit) activity.
  • Without real commitment from international policymakers to enforcing the arms embargo and protecting the economy from being weaponized, Libya will be consigned to sustained conflict, further fragmentation and potential economic collapse. Given the likely absence of a political settlement in the short term, international policymakers should seek to curtail the continued expansion of the conflict economy by reducing armed groups’ engagement in economic life.
  • In order to reduce illicit activities, international policymakers should develop their capacity to identify and target chokepoints along illicit supply chains, with a focus on restraining activities and actors in closest proximity to violence. Targeted sanctions against rent maximizers (both armed and unarmed) is likely to be the most effective strategy. More effective investigation and restraint of conflict economy actors will require systemic efforts to improve transparency and enhance the institutional capacity of anti-corruption authorities. International policymakers should also support the development of tailored alternative livelihoods that render conflict economy activities less attractive.

Event participants

Mohammed Masbah, Director, Moroccan Institute for Policy Analysis; Associate Fellow, MENA Programme, Chatham House
Moderator: Lina Khatib, Director, MENA Programme, Chatham House

Ever since independence, the Moroccan monarchy has used political parties to legitimize the country’s authoritarian political process and structure, and to absorb social and political anger. The palace puts successive governments and other elected institutions, such as local and regional councils, at the frontline of public blame, and replaces them once they fail this function.

In a recent article, MENA Programme Associate Fellow, Mohammed Masbah, examines how the Moroccan monarchy has used this strategy with the ruling Justice and Development Party (PJD) so that the palace remains the centre of political power, while the PJD – and other political parties before it– takes responsibility for coping with the mounting socio-economic crisis.

In this webinar, part of the Chatham House project on The Future of the State in the Middle East and North Africa, the article’s author will discuss the risks this approach presents for the long-term stability of Morocco and what reforms are needed to increase citizens’ dwindling confidence in the political process.

Webinar: Federalism in a Fragmented State: Rethinking Decentralization in Yemen

Research Event

15 April 2020 - 1:00pm to 2:00pm

Event participants

Osamah Al Rawhani, Deputy Director, Sana’a Center for Strategic Studies
Moderator: Nadim Houry, Executive Director, Arab Reform Initiative

Yemen suffered from the excessive control of the central government prior to the current conflict. Federalism has been put forward by many Yemeni political parties since the National Dialogue Conference (NDC) as the supposed magic cure for this significant problem. Today, Yemen is more fragmented than ever, its state central institutions have been scattered and lack leadership and the state has lost most of its sovereignty. The prevailing narrative that decentralization through federalism is Yemen’s inevitable path post-conflict often fails to acknowledge that there are prerequisites for effective local governance, beyond political will.  

In a recent article, Osamah Al Rawhani addressed how the weakness of central state institutions is the key challenge to proceeding with federalism in Yemen and highlighted prerequisites and contextual factors that need to be addressed before reforming the structure of the state. He argued that the viability of decentralization relies on the presence of a functioning, representative central government that is capable of devolving power but also able to keep the state from further fragmentation. 

In this webinar, part of the Chatham House project on The Future of the State in the Middle East and North Africa, the article’s author will discuss recent developments in Yemen, where shifting frontlines and regional divisions are fragmenting the country in new ways. The speaker will explore alternative approaches to pursue the path of federalism that recognize the current realities and the critical need for strong central institutions. He will also survey the internal and external factors that must be considered to rebuild a stable state in Yemen.

Why is it So Hard for Iraq to Form A Government?

Mustafa al-Kadhimi has emerged as the compromise prime minister designate, but his potential appointment is built on shaky foundations.

On April 9, Iraqi President Barham Salih gathered the Shia, Kurdish and Sunni political blocs at the presidential palace to task head of intelligence Mustafa al-Kadhimi with forming a government.

Kadhimi is the third prime minister-designate assigned since Prime Minister Adil abd al-Mehdi resigned in November, in the wake of mass protests against government corruption and the country’s ethno-sectarian based political system.

Kadhimi’s two predecessors, Muhammad Tawfiq Allawi and Adnan al-Zurfi, both failed to form a government. This third attempt came as Iraq struggles with repeated crises since October 2019, when the government began responding with deadly force to large-scale mass protests, killing more than 600 and injuring tens of thousands.

In January, the assassination of Qasem Soleimani escalated tensions between the United States and Iran, with Iraq stuck in the middle and becoming the home for regular tit-for-tat attacks. The Islamic State — never completely defeated — took advantage of these crises and increased its attacks in disputed territories.

The outbreak of COVID-19 challenges the country’s fragile public health sector, while the decline in the price of oil will make it harder for leaders to pay the public salaries that keep the system (and patronage) moving.

What does the delay in forming a government amid multiple crises mean for the post-2003 Iraqi political system?

Iraq’s post-2003 political system is designed to withstand crisis. Over the years, political parties reflecting the country’s ethnic and sectarian divides have had a tacit understanding that crises represent a risk to their collective interests. These elite stakeholders have together weathered civil war, insurgency and multiple protests — despite deep conflicts with one another.

For instance, in September 2018 protesters attacked most major political party headquarters and the Iranian consulate in Basra, and authorities killed some 20 protesters.

Since the May election of that year, the fragmented Shia elite had been unable to even declare which side has the largest parliamentary bloc, let alone decide on a government.

But after the September crisis, the previously gridlocked parties swiftly came together to form an “understanding” that pushed through the impasse leading to the Mehdi government. In 2020, however, Iraq’s political parties were slower to come back together despite the multiple crises — far greater than 2018. The system is less able to swiftly fix itself, based primarily on the fragmentation of the elite — and their determination to prevent any challenge to their rule.

Why did the two prior attempts fail?

The two previous prime minister-designates each fell short for different reasons. When I met Allawi in February at the prime minister’s guesthouse in Baghdad, he was very clearly convinced that his mandate was to sideline the parties.

He hoped that simply choosing technocratic ministers outside the elite pact, with the support of Moqtada al-Sadr behind him, would garner support from protesters and the disillusioned public. He failed, however, because his cabinet had to go through parliament and the parties rejected what they saw a threat to the elite pact and the system.

Zurfi similarly failed after being directly appointed in March by Salih after the Shia parties failed to come up with a candidate. From the beginning, then, Zurfi faced challenges because parties were not in agreement. He attempted to directly confront his opposition, and spoke out against Iranian influence in Iraq. As a result, Zurfi was unable to even get to parliament with his proposed cabinet, as the Shia parties got back together to bring him down.

The failure of both strategies — Allawi attempting to work outside the elite party system and Zurfi trying to target certain parties — reveals tensions in Iraq’s political system. This fragmentation strains the parties’ ability to swiftly unite, and the system’s ability to withstand crises.

The endemic problems are a consequence of fragmentation, including the failure following the 2018 elections to declare governing parliamentary bloc. Moreover, after that election, newcomers into the political system (two-thirds of the MPs are serving their first term) are increasingly making their own demands and less willing to blindly toe party lines.

Can Kadhimi overcome the impasse?

Kadhimi’s appointment as prime minister-designate nonetheless is on shaky foundations. His appointment had previously faced a veto from Iran and its allied groups which make up the Fateh bloc. Kataeb Hezbollah, an armed group close to Iran and linked to the Popular Mobilization Units, issued a statement accusing Kadhimi with blood on his hands for the deaths of Soleimani and Abu Mahdi al-Muhandis.

Many Fateh bloc members had for months vetoed Kadhimi’s name due to this allegation. Immediately before Kadhimi addressed the nation for the first time, Iraqi state television broadcast a prerecorded statement by PMU (and Fateh) leader Qais al-Khazali, who had also previously accused Kadhimi of spying for the Americans and being complicit in the two killings.

Khazali, who commands the second-largest party within Fateh, accepted the party line to back Kadhimi but came out with his own conditions on television. However, the concerns about the COVID-19 crisis and the collapse of the price of oil finally brought all sides to compromise — a design of the political system.

Kadhimi has signalled he will play by the old rules with these stakeholders. Because of the magnitude of these simultaneous crises, Iraqi politics is moving back to the post-2003 norm. The ethno-sectarian based political system is geared to weather such existential crises more than it is to handling day-to-day governance. Despite the notion of “post-sectarianism” in Iraq, this system is based on ethno-sectarian political party compromise.

In his television address, Khazali, who had previously attempted to move away from sectarian language, explained that the process of selecting a prime minister is reserved to the Shia, who have the right as the majority, and not to Salih, a Kurd.

Over the years Kadhimi has expressed an admiration of the bravery of the protesters and of the importance of civil society. Many Iraqi civil society activists owe their lives to the work of the former intelligence chief. However, he has also been part of the same system that has violently suppressed protesters.

As the compromise prime minister-designate, he will find it difficult to transform his country as long as he plays by the rules of post-2003 Iraq — an irony not lost on the protesters who immediately rejected the candidacy of a man whom until recently many protesters had supported.

Can Protest Movements in the MENA Region Turn COVID-19 Into an Opportunity for Change?

29 April 2020

Dr Georges Fahmi

Associate Fellow, Middle East and North Africa Programme
The COVID-19 pandemic will not in itself result in political change in the MENA region, that depends on the ability of both governments and protest movements to capitalize on this moment. After all, crises do not change the world - people do.

COVID-19 has offered regimes in the region the opportunity to end popular protest. The squares of Algiers, Baghdad, and Beirut – all packed with protesters over the past few months – are now empty due to the pandemic, and political gatherings have also been suspended. In Algeria, Iraq and Lebanon, COVID-19 has achieved what snipers, pro-regime propaganda, and even the economic crisis, could not.

Moreover, political regimes have taken advantage of the crisis to expand their control over the political sphere by arresting their opponents, such as in Algeria where the authorities have cracked down on a number of active voices of the Hirak movement. Similarly, in Lebanon, security forces have used the pandemic as an excuse to crush sit-ins held in Martyr’s Square in Beirut and Nour Square in Tripoli.

However, despite the challenges that the pandemic has brought, it also offers opportunities for protest movements in the region. While the crisis has put an end to popular mobilization in the streets, it has  created new forms of activism in the shape of solidarity initiatives to help those affected by its consequences.

In Iraq, for example, protest groups have directed their work towards awareness-raising and sharing essential food to help mitigate the problem of food shortages and rising prices across the country. In Algeria, Hirak activists have run online campaigns to raise awareness about the virus and have encouraged people to stay at home. Others have been cleaning and disinfecting public spaces. These initiatives increase the legitimacy of the protest movement, and if coupled with political messages, could offer these movements an important chance to expand their base of popular support.

Exposes economic vulnerability

Economic grievances, corruption and poor provision of public services have been among the main concerns of this recent wave of protests. This pandemic only further exposes the levels of economic vulnerability in the region. COVID-19 is laying bare the socio-economic inequalities in MENA countries; this is particularly evident in the numbers of people engaged in the informal economy with no access to social security, including health insurance and pensions.

Informal employment, approximately calculated by the share of the labour force not contributing to social security, is estimated to amount to 65.5% of total employment in Lebanon, 64.4% in Iraq, and 63.3% in Algeria. The crisis has underscored the vulnerability of this large percentage of the labour force who have been unable to afford the economic repercussions of following state orders to stay at home.

The situation has also called attention to the vital need for efficient public services and healthcare systems. According to the fifth wave of the Arab Barometer, 74.4% of people in Lebanon are dissatisfied with their country’s healthcare services, as are 67.8% of people in Algeria and 66.5% in Iraq.

Meanwhile, 66.2% of people in Lebanon believe it is necessary to pay a bribe in order to receive better healthcare, as do 56.2% of people in Iraq and 55.9% in Algeria. The COVID-19 crisis has highlighted the need for more government investment in public healthcare systems to render them more efficient and less corrupt, strengthening the protesters’ case for the need for radical socio-economic reforms.

On the geopolitical level, the crisis puts into question the stability-focused approach of Western powers towards the region. For years, Western powers have directed their aid towards security forces in the interests of combating terrorism but COVID-19 has proved itself to be a much more lethal challenge to both the region and the West.

Facing this new challenge requires international actors to reconsider their approach to include supporting health and education initiatives, as well as freedom of expression and transparency. As argued by Western policymakers themselves, it was China’s lack of transparency and slow response that enabled the proliferation of the virus, when it could have been contained in Wuhan back in December 2019.

This crisis therefore offers regional protest movements the opportunity to capitalize on this moment and push back against the policies of Western powers that have invested in regional stability only to the extent of combating Islamic jihad. 

But crises do not change the world, people do. The COVID-19 pandemic will not in itself result in political change in the MENA region. Rather, it brings opportunities and risks that, when exploited, will allow political actors to advance their own agendas. While the crisis has put an end to popular mobilization and allowed regimes to tighten their grip over the political sphere, behind these challenges lie real opportunities for protest movements.

The current situation represents a possibility for them to expand their popular base through solidarity initiatives and has exposed more widely the importance of addressing socio-economic inequalities. Finally, it offers the chance to challenge the stability-focused approach of Western powers towards the region which until now has predominantly focused on combating terrorism.

Lebanese Women and the Politics of Disruption

Research Event

6 May 2020 - 1:00pm to 2:00pm

Event participants

Carmen Geha, Assistant Professor of Public Administration, Leadership and Organisational Development, American University of Beirut
Moderator: Lina Khatib, Director, Middle East and North Africa Programme, Chatham House
Lebanese women have been at the forefront of the protest movement that has shaken Lebanon since October 2019. The active participation by women and their visibility in Lebanon's protest movement has challenged the gender norms prevalent in Lebanese society and politics. However, the COVID-19 pandemic and the nationwide lockdown that ensued has disrupted women's ability to organize, and is threatening the fragile progress towards female inclusion in the political process.
 
In a recent article, Carmen Geha discussed the politics of representation in the context of women's participation in public life in Lebanon and argued that the country's political system is maintained through tightly-knit informal power relations among sectarian politicians, making women's participation in politics virtually impossible. The article explained how the October 2019 revolution challenged that norm by creating inclusive spaces where women activists could confront politicians and thus, transform the way women participate in politics and public life.
 
In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, the article's author will discuss how women's activism in Lebanon has been affected by the coronavirus-induced lockdown. The speaker will consider how, under current circumstances, women activists can speak up collectively and bring back a movement to contest gender norms in order to build an alternative political model that can better represent women's priorities.

3-year freedom from progression following 68GaPSMA PET CT triaged management in men with biochemical recurrence post radical prostatectomy. Results of a prospective multi-center trial.

Background: 68Ga PSMA PET CT (PSMA) is increasingly used in men with biochemical recurrence (BCR) post radical prostatectomy (RP), but its longer term prognostic / predictive potential in these men is unknown. The aim of this study was to evaluate the predictive value of PSMA PET for 3 year freedom from progression (FFP) in men with BCR post RP undergoing salvage radiotherapy (sRT). Methods: This prospective multi-center study enrolled 260 men between 2015 and 2017. Eligible patients were referred for PSMA with rising PSA following RP. Management following PSMA was recorded but not mandated. PSMA protocols were standardised across sites and reported prospectively. Clinical, pathological and surgical information, sRT, timing and duration of androgen deprivation (ADT), 3 year PSA results and clinical events were documented. FFP was defined as a PSA rise ≤ 0.2ng/mL above nadir post sRT, with no additional treatment. Results: The median PSA was 0.26ng/mL (IQR 0.15 - 0.59) and follow-up 38 months (IQR 31-43). PSMA was negative in 34.6% (90/260), confined to prostate fossa 21.5% (56/260), pelvic nodes 26.2% (68/260), and distant disease 17.7% (46/260). 71.5% (186/260) received sRT, 38.2% (71/186) to the fossa only, 49.4% (92/186) fossa + pelvic nodes and 12.4% (23/186) nodes alone/SBRT. PSMA was highly predictive of FFP at 3 years following sRT. Overall, FFP was achieved in 64.5% (120/186) of those who received sRT, 81% (81/100) with negative/fossa confined vs. 45% (39/86) for extra fossa disease (p<0.0001). On logistic regression PSMA was more independently predictive of FFP than established clinical predictors, including PSA, T-stage, surgical margin status or Gleason score (P < 0.002). 32% of men with a negative PSMA PET did not receive treatment. Of these, 66% (19/29) progressed, with a mean rise in PSA of 1.59ng/mL over the 3 years. Conclusion: PSMA PET result is highly predictive of FFP at 3 years in men undergoing sRT for BCR following RP. In particular, men with negative PSMA PET or disease identified as still confined to the prostate fossa demonstrate high FFP, despite receiving less extensive radiotherapy and lower rates of additional ADT than those with extra fossa disease.

Evaluation of dosimetry, quantitative methods and test-retest variability of 18F-PI-2620 PET for the assessment of tau deposits in the human brain

18F-PI-2620 is a next generation tau positron emission tomography (PET)-tracer that has demonstrated ability to image the spatial distribution of suspected tau pathology. The objective of this study was to assess the tracer biodistribution, dosimetry and quantitative methods of 18F-PI-2620 in the human brain. Full kinetic modelling approaches to quantify tau load were investigated. Non-invasive kinetic modeling approaches and semi-quantitative methods were evaluated against the full tracer kinetics. Finally, the reproducibility of PET measurements from test and retest scans was assessed. Methods: Three healthy controls (HC) and 4 Alzheimer disease (AD) subjects underwent two dynamic PET scans including arterial sampling. Distribution volume ratio (DVR) was estimated using full tracer kinetics (2 Tissue Compartment (2TC) models, Logan Graphical Analysis (LGA)) and non-invasive kinetic models (Non-Invasive Logan Graphical Analysis (NI-LGA) and the multilinear reference tissue model (MRTM2)). Standardized uptake value ratio (SUVR) was determined at different imaging windows after injection. Correlation between DVR and SUVR, effect size (Cohen’s d) and test-retest variability (TRV) were evaluated. Additionally, 6 HC subjects received one tracer administration and underwent whole-body PET for dosimetry calculation. Organ doses and the whole-body effective dose were calculated using OLINDA 2.0. Results: Strong correlation was found across different kinetic models (R2 >0.97) and between DVR(2TC) and SUVRs between 30 to 90 min with R2>0.95. Secular equilibrium was reached around 40 min post injection (p.i.) in most regions and subjects. The TRV and effect size for the SUVR across different regions was similar at 30-60 min (TRV=3.8%, d=3.80), 45-75 min (TRV=4.3%, d=3.77) and 60-90 min (TRV=4.9%, d=3.73) and increased at later time points. Elimination was via the hepatobiliary and urinary system. The whole-body effective dose was determined to be 33.3±2.1 μSv/MBq for an adult female and 33.1±1.4 μSv/MBq for an adult male with a 1.5 hour urinary bladder voiding interval. Conclusion: 18F-PI-2620 exhibits fast kinetics, suitable dosimetry and low TRV. DVR measured using the 2TC model with arterial sampling correlated strongly with DVR measured by NI-LGA, MRTM2 and SUVR. SUVR can be used for 18F-PI-2620 PET quantification of tau deposits avoiding arterial blood sampling. Static 18F-PI-2620 PET scans between 45-75min p.i. provide excellent quantification accuracy, large effect size and low TRV.

Combined Visual and Semi-quantitative Evaluation Improves Outcome Prediction by Early Mid-treatment 18F-fluoro-deoxi-glucose Positron Emission Tomography in Diffuse Large B-cell Lymphoma.

The purpose of this study was to assess the predictive and prognostic value of interim FDG PET (iPET) in evaluating early response to immuno-chemotherapy after two cycles (PET-2) in diffuse large B-cell lymphoma (DLBCL) by applying two different methods of interpretation: the Deauville visual five-point scale (5-PS) and a change in standardised uptake value by semi-quantitative evaluation. Methods: 145 patients with newly diagnosed DLBCL underwent pre-treatment PET (PET-0) and PET-2 assessment. PET-2 was classified according to both the visual 5-PS and percentage SUV changes (SUV). Receiver operating characteristic (ROC) analysis was performed to compare the accuracy of the two methods for predicting progression-free survival (PFS). Survival estimates, based on each method separately and combined, were calculated for iPET-positive (iPET+) and iPET-negative (iPET–) groups and compared. Results: Both with visual and SUV-based evaluations significant differences were found between the PFS of iPET– and iPET+ patient groups (p<0.001). Visually the best negative (NPV) and positive predictive value (PPV) occurred when iPET was defined as positive if Deauville score 4-5 (89% and 59%, respectively). Using the 66% SUV cut-off value, reported previously, NPV and PPV were 80 and 76%, respectively. SUV at 48.9% cut-off point, reported for the first time here, produced 100% specificity along with the highest sensitivity (24%). Visual and semi-quantitative SUV<48.9% assessment of each PET-2 gave the same PET-2 classification (positive or negative) in 70% (102/145) of all patients. This combined classification delivered NPV and PPV of 89% and 100% respectively, and all iPET+ patients failed to achieve or remain in remission. Conclusion: In this large consistently treated and assessed series of DLBCL, iPET had good prognostic value interpreted either visually or semi-quantitatively. We determined that the most effective SUV cut-off was at 48.9%, and that when combined with visual 5-PS assessment, a positive PET-2 was highly predictive of treatment failure.

Long term follow-up and outcomes of re-treatment in an expanded 50 patient single-center phase II prospective trial of Lutetium-177 (177Lu) PSMA-617 theranostics in metastatic castrate-resistant prostate cancer

Objectives: Lutetium-177 (177Lu)-PSMA-617 (LuPSMA) is a radioligand with high affinity for prostate specific membrane antigen (PSMA) enabling targeted beta-irradiation of prostate cancer. We have previously reported favorable activity with low toxicity in a prospective phase II trial involving 30 men with metastatic castrate-resistant prostate cancer (mCRPC). We now report their longer-term outcomes including a 20 patient extension cohort and outcomes of subsequent systemic treatments following completion of trial therapy. Methods: 50 patients with PSMA-avid mCRPC who had progressed after standard therapies received up to 4 cycles of LuPSMA every 6 weeks. Endpoints included PSA response (PCWG2), toxicity (CTCAE v4.03), imaging response, patient-reported health-related quality of life (QoL), progression-free and overall survival. We also describe, as a novel finding, outcomes of men who subsequently progressed and had further systemic therapies, including LuPSMA. Results: 75 men were screened to identify 50 patients eligible for treatment. Adverse prognostic features of the cohort included short median PSA doubling time (2.3 months) and extensive prior treatment including prior docetaxel (84%), cabazitaxel (48%), and abiraterone and/or enzalutamide (90%). The mean administered radioactivity was 7.5 GBq/cycle. PSA decline ≥ 50% was achieved in 32 of 50 patients (64%, 95% CI 50-77%), including 22 patients (44%, 95% CI 30-59%) with ≥ 80% decrease. Of 27 patients with measurable soft tissue disease, 15 (56%) achieved an objective response by RECIST 1.1. The most common toxicities attributed to LuPSMA were self-limiting G1-2 dry mouth (66%), transient G1-2 nausea (48%), G3-4 thrombocytopenia (10%) and G3 anemia (10%). Brief pain inventory severity and interference scores decreased at all time points including at the 3 month follow-up with a decrease of -1.2 (95% CI -0.5 to -1.9, P = 0.001) and 1.0 (95% CI -0.2 to -0.18, P = 0.013), respectively. At a median follow-up of 31.4 months, median OS was 13.3 months (95% CI 10.5-18.7) with a significantly longer survival of 18.4 months (95% CI 13.8-23.8) in patients achieving a PSA decline ≥ 50%. At progression following prior response, further LuPSMA was administered to 15 (30%) patients (median 2 cycles commencing 359 days from enrolment) with PSA decline ≥ 50% in 11 patients (73%). 4 of 21 patients (19%) receiving other systemic therapies upon progression experienced PSA decline ≥ 50%. There were no unexpected adverse events with LuPSMA re-treatment. Conclusion: This expanded 50 patient cohort of men with extensive prior therapy confirms our earlier report of high response rates, low toxicity and improved QoL with LuPSMA radioligand therapy. Upon progression, re-challenge LuPSMA demonstrated higher response rates than other systemic therapies.

Pre-treatment 18F-FDG PET/CT Radiomics predict local recurrence in patients treated with stereotactic radiotherapy for early-stage non-small cell lung cancer: a multicentric study

Purpose: The aim of this retrospective multicentric study was to develop and evaluate a prognostic FDG PET/CT radiomics signature in early-stage non-small cell lung cancer (NSCLC) patients treated with stereotactic radiotherapy (SBRT). Material and Methods: Patients from 3 different centers (n = 27, 29 and 8) were pooled to constitute the training set, whereas the patients from a fourth center (n = 23) were used as the testing set. The primary endpoint was local control (LC). The primary tumour was semi-automatically delineated in the PET images using the Fuzzy locally adaptive Bayesian algorithm, and manually in the low-dose CT images. A total of 184 IBSI-compliant radiomic features were extracted. Seven clinical and treatment parameters were included. We used ComBat to harmonize radiomic features extracted from the four institutions relying on different PET/CT scanners. In the training set, variables found significant in the univariate analysis were fed into a multivariate regression model and models were built by combining independent prognostic factors. Results: Median follow-up was 21.1 (1.7 – 63.4) and 25.5 (7.7 – 57.8) months in training and testing sets respectively. In univariate analysis, none of the clinical variables, 2 PET and 2 CT features were significantly predictive of LC. The best predictive models in the training set were obtained by combining one feature from PET, namely information correlation 2 (IC2) and one from CT (Flatness), reaching a sensitivity of 100% and a specificity of 96%. Another model combining 2 PET features (IC2 and Strength), reached sensitivity of 100% and specificity of 88%, both with an undefined hazard ratio (HR) (p<0.001). The latter model obtained an accuracy of 0.91 (sensitivity 100%, specificity 81%), with a HR undefined (P = 0.023) in the testing set, however other models relying on CT radiomics features only or the combination of PET and CT features failed to validate in the testing set. Conclusion: We showed that two radiomic features derived from FDG PET were independently associated with LC in patients with NSCLC undergoing SBRT and could be combined in an accurate predictive model. This model could provide local relapse-related information and could be helpful in clinical decision-making.

Radiation Dosimetry in 177Lu-PSMA-617 Therapy Using a Single Post-treatment SPECT/CT: A Novel Methodology to Generate Time- and Tissue-specific Dose Factors

Calculation of radiation dosimetry in targeted nuclear medicine therapies is traditionally resource-intensive requiring multiple post-therapy SPECT acquisitions. An alternative approach is to take advantage of existing pharmacokinetic data from these smaller cohorts to enable dose computation from a single post-treatment scan in a manner that may be applied to a much broader patient population. Methods: In this work, a technical description for simplified dose estimation is presented and applied to assessment of 177Lu-PSMA-617 therapy (Prostate-Specific Membrane Antigen) for metastatic prostate cancer. By normalizing existing time-activity curves to a single measurement time, it is possible to calculate a mean and range of time-integrated activity values which relate to radiation absorbed dose. To assist with accurate pharmacokinetic modelling of the training cohort, a method for contour-guided image registration was developed. Results: Tissue-specific dose conversion factors for common post-treatment imaging times are reported along with a characterization of added uncertainty in comparison to a traditional serial imaging protocol. Single time point dose factors for tumor were determined to be 11.0, 12.1, 13.6, and 15.2 Gy per MBq/mL at image times of 24, 48, 72, and 96 hours, respectively. For normal tissues, parotid gland factors were 6.7, 9.4, 13.3, and 19.3 Gy per MBq/mL and kidneys were 7.1, 10.3, 15.0, and 22.0 Gy per MBq/mL at those times. Tumor dose estimates were most accurate using delayed scanning at times beyond 72 hours. Dose to healthy tissues is best characterized by scanning patients in the first two days of treatment owing to the larger degree of tracer clearance in this early phase. Conclusion: The work demonstrates a means for efficient dose estimation in 177Lu-PSMA-617 therapy. By providing methods to simplify and potentially automate radiation dosimetry we hope to accelerate the understanding of radiobiology and development of dose-response models in this unique therapeutic context.

11C-Methionine PET Identifies Astroglia Involvement in Heart-Brain Inflammation Networking after Acute Myocardial Infarction

Acute myocardial infarction (MI) triggers a local and systemic inflammatory response. We recently showed microglia involvement using TSPO imaging. Here, we evaluate whether 11C-methionine provides further insights into heart-brain inflammation networking. Methods: Male Bl6N mice underwent permanent coronary artery ligation followed by 11C-methionine PET at 3 and 7 days (n = 3). In subgroups, leukocyte homing was blocked by integrin antibodies (n = 5). The cellular substrate for PET signal was identified using brain section immunostaining. Results: 11C-methionine uptake peaked in the MI region at d3 (5.9±0.9vs 2.4±0.5 %ID/cc), decreasing to control level by d7 (4.3±0.6 %ID/cc). Brain uptake was proportional to cardiac uptake (r=0.47,p<0.05), peaking also at d3 (2.9±0.4vs 2.4±0.3 %ID/cc) and returning to baseline at d7 (2.3±0.4 %ID/cc). Integrin blockade reduced uptake at every time point. Immunostaining at d3 revealed co-localization of the L-type amino acid transporter with GFAP-positive astrocytes but not CD68-positive microglia. Conclusion: PET imaging with 11C-methionine specifically identifies an astrocyte component, enabling further dissection of the heart-brain axis in post MI inflammation.

Quantitative test-retest measurement of 68Ga-PSMA-HBED-CC (PSMA-11) in tumor and normal tissue

The PET radiotracer 68Ga-PSMA-HBED-CC (68Ga-PSMA-11) shows potential as an imaging biomarker for recurrent and metastatic prostate cancer. The purpose of this study was to determine repeatability of 68Ga-PSMA-HBED-CC in a test-retest trial in subjects with metastatic prostate adenocarcinoma. Methods: Subjects with metastatic prostate cancer underwent two PET/CT scans with 68Ga-PSMA-HBED-CC within 14 days (mean 6 ± 4 d). Lesions in bone, nodes, prostate/bed, and visceral organs as well as representative normal tissues (salivary glands and spleen) were segmented separately by two readers. Absolute and percent differences in SUVmax and SUVmean were calculated for all test-retest regions. Repeatability was assessed using percentage difference, within-subject coefficient of variation (wCV), repeatability coefficient (RC), and Bland-Altman analysis. Results: 18 subjects were evaluated, 16 of which demonstrated local or metastatic disease on 68Ga-PSMA-HBED-CC PET/CT. A total of 136 lesions were segmented in bone (n = 99), nodes (n = 27), prostate/bed (n = 7), and viscera (n = 3). The wCV for SUVmax was 11.7% for bone lesions and 13.7% for nodes. The RC was ±32.5% SUVmax for bone lesions and ±37.9% SUVmax for nodal lesions, meaning 95% of the normal variability between two measurements will be within these numbers, so larger differences are likely attributable to true biological changes in tumor rather than normal physiologic or measurement variability. wCV in the salivary glands and spleen was 8.9% and 10.7% SUVmean, respectively. Conclusion: Repeatability measurements for PET/CT test-retest with 68Ga-PSMA-HBED-CC show a wCV 12-14% SUVmax and RC ±33-38% SUVmax in bone and nodal lesions. These estimates are an important aspect of 68Ga-PSMA-HBED-CC as a quantitative imaging biomarker. These estimates are similar to those reported for 18F-FDG, suggesting that 68Ga-PSMA-HBED-CC PET/CT may be useful in monitoring response to therapy.

Quantitative 3D assessment of 68Ga-DOTATOC PET/MRI with diffusion-weighted imaging to assess imaging markers for gastroendopancreatic neuroendocrine tumors: Preliminary results

68Ga-DOTATOC-PET/MRI (68Gallium-DOTATOC-positron emission tomography/magnetic resonance imaging) combines the advantages of PET in the acquisition of metabolic-functional information with the high soft tissue contrast of MRI. Standardized uptake values (SUV) in tumors were suggested as a measure of somatostatin receptor expression. A challenge with receptor ligands is, that the distribution volume is confined to tissues with tracer-uptake, potentially limiting SUV quantification. In this study, different functional, three-dimensional (3D) SUV, apparent diffusion coefficient (ADC) parameters and arterial tumor enhancement were tested for the characterization of gastroendopancreatic neuroendocrine tumors (GEP-NET). Methods: For this single-center, cross-sectional study, 22 patients with 24 histologically confirmed GEP-NET lesions (15 men/7 women; median, 61 years, range, 43-81 years), who received hybrid 68Ga-DOTA-PET/MRI examinations at 3T between January 2017 and July 2019 met eligibility criteria. SUVs, tumor-to-background ratios (TBR), the total functional tumor volume (TFTV), ADCmean and ADCmin were measured based on volumes of interest (VOI) and examined with receiver operating characteristic analysis to determine cut-off values for differentiation between low and intermediate grade GEP-NET. Spearman’s rank correlation coefficients were used to assess correlations between functional imaging parameters. Results: The ratio of PET-derived SUVmean and diffusion-weighted imaging (DWI)-derived ADCmin was introduced as a combined variable to predict tumor grade, outperforming single predictors. Based on a threshold ratio of 0.03 to be exceeded, tumors could be classified as grade 2 with a sensitivity of 86% and specificity of 100%. SUV and functional ADC values as well as arterial contrast enhancement parameters showed non-significant and mostly negligible correlations. Conclusion: As receptor density and tumor cellularity appear to be independent, potentially complementary phenomena, the combined PET/MRI ratio SUVmean/ADCmin may be used as a novel biomarker, allowing to differentiate between grade 1 and 2 GEP-NET.

Head to head prospective comparison of quantitative lung scintigraphy and segment counting in predicting pulmonary function of lung cancer patients undergoing video-assisted thoracoscopic lobectomy

Prediction of post-operative pulmonary function in lung cancer patients before tumor resection is essential for patient selection for surgery and is conventionally done with a non-imaging segment counting method (SC) or a two-dimensional planar lung perfusion scintigraphy (PS). The purpose of this study was to compare quantitative analysis of PS to single photon emission computed tomography/computed tomography (SPECT/CT) and to estimate the accuracy of SC, PS and SPECT/CT in predicting post-operative pulmonary function in patients undergoing lobectomy. Methods: Seventy-five non-small cell lung cancer (NSCLC) patients planned for lobectomy were prospectively enrolled (68% males, average age 68.1±8 years ). All patients completed pre-operative forced expiratory volume capacity (FEV1), diffusing capacity of the lung for carbon monoxide (DLCO), Tc99m-MAA lung perfusion scintigraphy with PS and SPECT/CT quantification. A subgroup of 60 patients underwent video-assisted thoracoscopic (VATS) lobectomy and measurement of post-operative FEV1 and DLCO. Relative uptake of the lung lobes estimated by PS and SPECT/CT were compared. Predicted post-operative FEV1 and DLCO were derived from SC, PS and SPECT/CT. Prediction results were compared between the different methods and the true post-operative measurements in patients who underwent lobectomy. Results: Relative uptake measurements differed significantly between PS and SPECT/CT in right lung lobes, with a mean difference of -8.2±3.8, 18.0±5.0 and -11.5±6.1 for right upper, middle and lower lobes respectively (p<0.001). The differences between the methods in the left lung lobes were minor with a mean difference of -0.4±4.4 (p>0.05) and -2.0±4.0 (p<0.001) for left upper and lower lobes respectively. No significant difference and strong correlation (R=0.6-0.76, p<0.001) were found between predicted post-operative lung function values according to SC, PS, SPECT/CT and the actual post-operative FEV1 and DLCO. Conclusion: Although lobar quantification parameters differed significantly between PS and SPECT/CT, no significant differences were found between the predicted post-operative lung function results derived from these methods and the actual post-operative results. The additional time and effort of SPECT/CT quantification may not have an added value in patient selection for surgery. SPECT/CT may be advantageous in patients planned for right lobectomies but further research is warranted.

Management of patients with renal failure undergoing dialysis during 131I therapy for thyroid cancer

Objectives: Radioactive iodine (131I) therapy may be used to treat thyroid cancer in end-stage renal disease patients who undergo hemodialysis. Because iodine predominantly utilizes renal clearance, treatment management in hemodialysis patients may be problematic, and no formal recommendations on hemodialysis currently exist. This work details our experience with treating thyroid cancer with iodine in chronic renal failure patients who require hemodialysis and details the therapeutic dosimetry results obtained during treatment to ensure that the dose to the bone marrow (BM) was acceptable. Methods: We treated 6 patients in the metabolic radiotherapy unit after thyroid stimulation. Two hemodialysis sessions in the metabolic radiotherapy unit were performed at 42 and 90 hours after radiopharmaceutical administration. BM toxicity was estimated with activity measurements from blood samples and with whole-body measurements that were regularly repeated during hospitalization and measured with a gamma counter. The patients underwent thyroid and hematologic monitoring to assess treatment efficacy and therapeutic toxicity in the short, medium and long term. Results: Whole-body activity was reduced on average by 66.7% [60.1-71.5] after the first dialysis session and by 53.3% [30.4-67.8] after the second. The mean estimated total absorbed dose to the BM was 0.992 Gy for all patients [0.431 – 2.323]. We did not observe any significant hematologic toxicity, and the clinical, biological and ultrasound test results confirmed the success of ablative treatment for the majority of patients. Conclusion: An approximately 30% reduction from the nominal dose in the amount of 131I activity for hemodialysis patients with thyroid cancer appears to strike an appropriate balance between the absence of BM toxicity and therapeutic efficacy. To avoid overirradiation, we recommend pretherapeutic dosimetry studies for metastatic patients to calculate the amount of activity to be administered as well as dosimetry monitoring during the hemodialysis sessions performed after therapeutic dose administration and under the same conditions.
