Matthew L. Meyerson, MD, PhD, on Lung Adenocarcinoma: Somatic Mutations, Germline Risk, and Ancestry
AACR Annual Meeting 2022
Matthew L. Meyerson, MD, PhD, of the Dana-Farber Cancer Institute, discusses study findings that suggest the variation in frequency of EGFR and KRAS mutations in lung cancer may be associated with genetic ancestry in patients from Latin America. The results indicate it may be possible to identify germline alleles underpinning this link. Finding a germline locus or loci may impact the development of lung cancers with these mutations and may improve lung cancer prevention and screening for populations of Latin American origin, as well as others.

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).

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses how research is building on the success of first-generation PARP inhibitors in the clinic and the potential of novel potent PARP1-selective inhibitors, which may lead to improved patient outcomes. Given recent advances in drug discovery, says Dr. Yap, we now can go beyond PARP by drugging other key DNA damage response targets in the clinic, including ATR, WEE1, DNA-PK, RAD51, POLQ, and USP1.

Christine A. Iacobuzio-Donahue, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses her research on the evolutionary features of advanced stage pancreatic cancers and the insights that may be used to help improve patient outcomes (Abstract PL05).

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from the PETRA study, a first-in-class, first-in-human trial of the next-generation PARP1-selective inhibitor AZD5305 in patients with BRCA1/2, PALB2, or RAD51C/D mutations in advanced or metastatic ovarian cancer, HER2-negative breast cancer, pancreatic, or prostate cancer. Target engagement was demonstrated across all dose levels, and antitumor activity was observed in selected tumor and molecular subtypes.

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).
