Silvia C. Formenti, MD, on Adapting Radiation Therapy to Immune Checkpoint Blockade
AACR Annual Meeting 2022
Silvia C. Formenti, MD, of Weill Cornell Medicine, discusses research on the best way to integrate radiotherapy with immune modifiers, which might require changes in standard radiation oncology practices. Variables such as the type of treatment fields, the inclusion of draining nodal stations, the degree of exposure of circulating immune cells, the type of dose fractionation, and the timing of radiotherapy during immune checkpoint blockade all can affect the success of immunoradiotherapy combinations (Abstract SY43).

Christine A. Iacobuzio-Donahue, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses her research on the evolutionary features of advanced stage pancreatic cancers and the insights that may be used to help improve patient outcomes (Abstract PL05).

Iván Márquez-Rodas, MD, PhD, of Spain’s Hospital General Universitario Gregorio Marañón, discusses final results of the phase II SPOTLIGHT203 study of systemic pembrolizumab in combination with intratumoral BO-112 for patients with advanced melanoma refractory to anti–PD-1–based therapy. The regimen achieved an overall response rate of 25% and a disease control rate of 65% (Abstract CT014).

Benoit You, MD, PhD, of the Lyon University Hospital (France), discusses phase I/II safety and efficacy results from the ENDOLA trial that combined olaparib with metronomic cyclophosphamide and metformin in patients with advanced pretreated endometrial cancer. At 10 weeks, the non–disease progression rate was 61.5%, reaching the primary endpoint of the study. Median progression-free survival was 5.1 months. Research on biomarkers of efficacy is ongoing (Abstract CT005).

Nicolas Girard, MD, PhD, of the Institut Curie, discusses findings from the phase III CheckMate 816 trial, which is the first study with an immunotherapy-based combination to demonstrate improved event-free survival and pathologic complete response in the neoadjuvant setting for patients with resectable stage IB to IIIA non–small cell lung cancer. The results may benefit the 30% to 55% of patients whose cancer recurs after surgery (Abstract CT012).

Matthew L. Meyerson, MD, PhD, of the Dana-Farber Cancer Institute, discusses study findings that suggest the variation in frequency of EGFR and KRAS mutations in lung cancer may be associated with genetic ancestry in patients from Latin America. The results indicate it may be possible to identify germline alleles underpinning this link. Finding a germline locus or loci may impact the development of lung cancers with these mutations and may improve lung cancer prevention and screening for populations of Latin American origin, as well as others.
