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).

Gautam Mehta, MD, of the U.S. Food and Drug Administration, discusses how accelerated approval of potentially life-saving cancer therapies has been applied in precision oncology. Although “fast-tracking” drugs presents opportunities and challenges, one possible measure of the program’s success is the fact that, to date, no solid tumor accelerated-approval indications have been withdrawn (Abstract DC06).

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).

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).

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).

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).
