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).
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).
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).
Zev Wainberg, MD, of the University of California, Los Angeles Medical Center, discusses preliminary data on the safety and efficacy of TTX-030, an anti-CD39 antibody, in combination with budigalimab and FOLFOX for the first-line treatment of locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. The study suggests the regimen may prove to be of benefit as a first-line treatment, regardless of combined positive score status (Abstract CT015).
Nickolas Papadopoulos, PhD, of the Sidney Kimmel Comprehensive Cancer Center, discusses early detection as the key to reducing cancer mortality and the lack of tests for many malignancies. Liquid biopsies have the potential to screen for various tumor types, albeit with varying levels of sensitivity. Dr. Papadopoulos discusses his research on such blood tests, following patients prospectively to find the best combination of genetic and epigenetic biomarkers to increase sensitivity (Abstract PL02).
Ari M. VanderWalde, MD, MPH, MBioeth, of The West Clinic, discusses results from the S1616 trial involving patients with metastatic or unresectable melanoma who had primary resistance to PD-1 or PD-L1 inhibitors. Compared with ipilimumab alone, the combination of ipilimumab plus nivolumab benefited some patients: those with tumors that responded to therapy showed an increased amount of CD8+ cells. Because there is no standard treatment for metastatic melanoma after failure of PD-1 inhibitors in BRAF wild-type disease, this research may provide a viable option in the future (Abstract CT013).
