Posttreatment high-grade gliomas are usually monitored with contrast-enhanced MRI, but its diagnostic accuracy is limited as it cannot adequately distinguish between true tumor progression and treatment-related changes. According to recent Response Assessment in Neuro-Oncology recommendations, PET overcomes this limitation. However, it is currently unknown which tracer yields the best results. Therefore, a systematic review and metaanalysis were performed to compare the diagnostic accuracy of the different PET tracers in differentiating tumor progression from treatment-related changes in high-grade glioma patients. Methods: PubMed, Web of Science, and Embase were searched systematically. Study selection, data extraction, and quality assessment were performed independently by 2 authors. Metaanalysis was performed using a bivariate random-effects model when at least 5 studies were included. Results: The systematic review included 39 studies (11 tracers). ¹⁸F-FDG (12 studies, 171 lesions) showed a pooled sensitivity and specificity of 84% (95% confidence interval, 72%–92%) and 84% (95% confidence interval, 69%–93%), respectively. O-(2-¹⁸F-fluoroethyl)-l-tyrosine (¹⁸F-FET) (7 studies, 172 lesions) demonstrated a sensitivity of 90% (95% confidence interval, 81%–95%) and specificity of 85% (95% confidence interval, 71%–93%). For S-¹¹C-methyl)-l-methionine (¹¹C-MET) (8 studies, 151 lesions), sensitivity was 93% (95% confidence interval, 80%–98%) and specificity was 82% (95% confidence interval, 68%–91%). The numbers of included studies for the other tracers were too low to combine, but sensitivity and specificity ranged between 93%–100% and 0%–100%, respectively, for ¹⁸F-FLT; 85%–100% and 72%–100%, respectively, for 3,4-dihydroxy-6-¹⁸F-fluoro-l-phenylalanine (¹⁸F-FDOPA); and 100% and 70%–88%, respectively, for ¹¹C-choline. Conclusion: ¹⁸F-FET and ¹¹C-MET, both amino-acid tracers, showed a comparably higher sensitivity than ¹⁸F-FDG in the differentiation between tumor progression and treatment-related changes in high-grade glioma patients. The evidence for other tracers is limited; thus, ¹⁸F-FET and ¹¹C-MET are preferred when available. Our results support the incorporation of amino-acid PET tracers for the treatment evaluation of high-grade gliomas.

Marking the release of MPI President Andrew Selee's latest book, speakers explore emerging trends in migration, economic interdependence, technology innovation, and cultural exchange that are transforming the relationship between the United States and Mexico, and the policy implications of these changes for the future.

Faced with a lack of employment opportunities and recurrent poverty, Albanian youth migrate to Italy alone in the hopes of improving their educational prospects or making money for their families. Yet upon arrival, they face many vulnerabilities. While some protections for unaccompanied minors exist in the Italy, the system is greatly fragmented and challenges, including how to return them to Albania, remain persistent.

This fact sheet uses U.S. and Mexican apprehensions data to trace the evolving trends in unaccompanied child and family migration from Central America through Mexico and to the United States, and discusses the push factors and pull factors responsible for the increase in flows seen in recent years, as well as the growing role of smuggling organizations.

A high school diploma has been a core requirement of proposed DREAM Act legislation and the Deferred Action for Childhood Arrivals (DACA) program. Yet a fresh estimate of the number of unauthorized immigrants graduating annually from U.S. high schools has long been missing from the debate. This fact sheet provides up-to-date estimates for the United States and top 15 states, estimating 98,000 such students graduate yearly.

This report analyzes the exploitation of migrants in three spheres: the domestic care sector, the labor market, and the sex industry. It details several obstacles governments face in their efforts to weaken the "bad actors" that profit from exploitation, and shows how one of the biggest challenges facing law enforcement is that serious criminals and lawbreakers often operate on the edge of legality and exploit legal routes wherever possible.

Having emerged from a long era of military rule, Myanmar's leaders and many citizens are looking outward. In particular, with Burmese labor migration abroad on the rise, policymakers are examining ways in which to harness remittances as a vehicle for economic development, particularly in impoverished rural areas. This article explores Burmese labor migration flows, financial reforms, and challenges on migration and development.

This event focuses on the changing face of Mexican migration to the United States, Mexican immigrants' contributions to U.S. society and political and economic power, as well as that of those who have returned to Mexico.

Colombia has more internally displaced persons (IDPs) than any other country in the world, the result of a 52-year civil war. Beyond improving the lives of its 7.3 million IDPs, the country faces a number of crucial migration issues as it works to achieve stability in the wake of an historic peace accord signed in late 2016. This country profile examines historical trends and current and future migration challenges in Colombia.

While emigration increased after Portugal plunged into an economically turbulent period amid the global financial crisis, the country's image as the poster child for post-crisis outmigration may be misplaced. This report explores the scale, drivers, and impact of emigration from Portugal since the turn of the millennium, and examines how the country can stem emigration and promote the return of emigrants.

This event with UN High Commissioner for Refugees António Guterres includes a discussion on the state of citizen security in Central America and the resulting humanitarian impact, featuring findings from Children on the Run, a UNHCR report based on interviews with more than 400 unaccompanied children from the region.

Marking the release of an MPI report, speakers on this webinar present an overview of regional immigration enforcement trends, including U.S. and Mexican apprehensions and deportations of both children and adults, along with a demographic, socioeconomic, and criminal profile of child and adult deportees.

This report examines the rising numbers of apprehensions and deportations of Central American children and adults by the United States and Mexico, and provides a demographic, socioeconomic, and criminal profile of deportees to El Salvador, Guatemala, and Honduras. The report traces how rising Mexican enforcement is reshaping regional dynamics and perhaps ushering in changes to long-lasting trends in apprehensions.

Migration and development policy discussions have edged closer to each other on the international stage. The adoption of the Global Compact for Migration in December 2018 marks an important milestone. As all eyes turn toward the compact’s implementation, this brief examines some of the key topics states have pledged to work more closely on—from labor migration and migrants’ rights, to returns and reintegration.

How did the U.S. border enforcement picture go in the span of two years from the lowest levels of illegal immigration since 1971 to a spiraling border security and humanitarian crisis? This report draws on enforcement and other data as well as analysis of changing migration trends and policies to tell this story. The authors outline key elements for a new strategy that can succeed over the long term.
