Priscilla K. Brastianos, MD, on CNS Metastases: Understanding Their Evolution and the Clinical Implications
AACR Annual Meeting 2022
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).

Tina Cascone, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses the findings of the phase II NeoCOAST study, which showed that combination immunotherapy with the anti–PD-L1 monoclonal antibody durvalumab and other novel agents resulted in numerically higher major pathologic response rates than durvalumab alone in the neoadjuvant setting for patients with early-stage resectable non–small cell lung cancer. Translational results also supported combination therapies over single-agent therapy (Abstract CT011).

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).

Alana L. Welm, PhD, of the University of Utah Huntsman Cancer Institute, discusses her findings of a new pathway that regulates the antitumor immune response during metastatic outgrowth. Interfering with a particular isoform of RON kinase may cause metastatic tumors to be swarmed by T cells and killed, suggesting that new approaches to targeting this kinase may be achievable in the near future (Abstract SY32).

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).

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).
