David A. Barbie, MD, on Mesothelioma: Activating the STING Pathway May Promote Antitumor Immunity
AACR Annual Meeting 2022
David A. Barbie, MD, of Dana-Farber Cancer Institute, discusses his laboratory’s studies, showing that malignant pleural mesothelioma, an inflamed cancer type with marginal response to immune checkpoint blockade, demonstrated high tumor cell STING expression and response to STING agonists in combination with natural killer cell therapies ex vivo. STING is the tumor cell stimulator of interferon genes (Abstract 4168).

Marcia R. Cruz-Correa, MD, PhD, of the University of Puerto Rico Comprehensive Cancer Center, discusses a way to possibly transform cancer outcomes by teaming up basic scientists, clinical researchers, and community advocates to work together, decode the complexity of cancer, and find points at which to intervene in the development of tumor cells. One strong focus is on communities disproportionately affected based on their genomic ancestry, geographic location, and ethnicity (Abstract PL06).

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).

Meenakshi Anurag, PhD, of Baylor College of Medicine, discusses results from the ALTERNATE trial, which showed the combination of anastrozole plus fulvestrant was superior to either drug alone in inhibiting tumor proliferation in postmenopausal women with early-stage luminal B breast cancer (Abstract CT026).

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).

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).
