Lillian L. Siu, MD, of Canada’s Princess Margaret Cancer Centre, discusses biomarker-driven precision cancer medicine, the optimal sequencing of immunotherapy (IO) with standard treatments in curative settings, IO targets beyond PD-1/PD-L1 and combinatorial strategies, and next-generation adoptive cell therapies (Abstract PL06).
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.
Priscilla K. Brastianos, MD, of Harvard Medical School and Massachusetts General Hospital, talks about her efforts to better understand how brain metastases evolve genomically and to test such agents as abemaciclib, paxalisib, and entrectinib, which may stop their growth. Palbociclib, a CDK inhibitor, has already shown potential benefit. A national cooperative group trial is underway in multiple centers to identify novel treatments for patients with brain metastases, who typically have a poor prognosis (Abstract SY38).
Josh Neman, PhD, of the Keck School of Medicine, University of Southern California, discusses the distribution of brain metastasis to preferential brain regions that vary according to cancer subtype, how neurotransmitters respond, and the ways in which the central nervous system acclimates (Abstract SY32).
Jia Luo, MD, of Dana-Farber Cancer Institute, discusses the emerging class of cancer therapies for allele-specific KRAS inhibitors and the importance of their distinct clinical, genomic, and immunologic features. Because KRAS G12D–mutated non–small cell lung cancer is associated with worse responses to immunotherapy, Dr. Luo believes drug development will need to take these differences into account (Abstract 4117).
Electra D. Paskett, PhD, of The Ohio State University, discusses various factors that may contribute to cancer such as socioeconomic status, discrimination, violence, and access to health care. When clinicians identify these factors and intervene with access to services, it may be possible to improve outcomes for their patients (Abstract SY33).
