Maria Elena Martinez, PhD, MPH, on Colorectal Cancer Screening in Underserved Populations: COVID, Silver Linings, and Challenges Ahead
AACR Annual Meeting 2022
Maria Elena Martinez, PhD, MPH, of the University of California, San Diego Moores Cancer Center, provides an overview of the key components of the Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science program, challenges posed by the COVID-19 pandemic, and opportunities for overcoming these challenges. Although screening and follow-up may reduce the incidence of and mortality from colorectal cancer, these disparities persist in medically underserved populations (Abstract SY30).

Patricia M. LoRusso, DO, of the Yale University School of Medicine, discusses how patients may benefit in the coming decade from discoveries about agents that target KRAS, and how important the approval of sotorasib turned out to be, as well as other agents in the research pipeline. Dr. LoRusso also talks about the scientific advances in tackling inhibition (Abstract SY20).

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).

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).

John B.A.G. Haanen, MD, PhD, of the Netherlands Cancer Institute, discusses findings from a phase I study designed to test the safety and efficacy of the CARVac (CAR-T cell-amplifying RNA vaccine) strategy to overcome poor CAR T-cell stimulation and responses in patients with CLDN6-positive advanced solid tumors. Men with testicular cancer in particular showed encouraging responses. Overall, some patients showed long-term CAR T-cell persistence more than 150 days post infusion. Partial responses seemed to deepen further over time (Abstract CT002).

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).
