Carmen E. Guerra, MD, MSCE, on Diversity, Equity, and Inclusion in Clinical Trials: Expert Commentary
2023 ASCO Annual Meeting
Carmen E. Guerra, MD, MSCE, of the University of Pennsylvania Abramson Cancer Center, discusses three key abstracts presented at ASCO: strategies to increase accrual of underrepresented populations in Alliance NCTN trials, how patient-clinician education can strengthen partnerships and improve diversity in breast and lung cancer trials, and mediators of racial and ethnic inequities in clinical trial participation among U.S. patients with cancer from 2011 to 2022 (Abstracts 6509, 6510, 6511).

Manali K. Kamdar, MD, of University of Colorado Hospital, discusses the treatment landscape for the 30% to 40% of patients with diffuse large B-cell lymphoma (DLBCL) whose disease will relapse. Patients who experience relapse within 1 year of chemoimmunotherapy have poor outcomes with autotransplantation, but chimeric antigen receptor T-cell therapy has shown efficacy and manageable toxicity.
The ASCO Post Staff
Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, discusses phase I/II results on the efficacy of nivolumab with or without ipilimumab in patients with recurrent or metastatic Merkel cell carcinoma. The study found that, for this rare and aggressive skin cancer, nivolumab showed clinical activity in advanced disease. However, these results from CheckMate 358 do not suggest an additional benefit with ipilimumab added to nivolumab (Abstract 9506).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Ticiana Leal, MD, of Winship Cancer Institute of Emory University, discuss the use of tumor treating fields therapy, in which electric fields disrupt processes critical for cancer cell viability. Already approved by the FDA to treat glioblastoma and mesothelioma, the treatment has extended overall survival in this phase III study of patients with metastatic non–small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy, without exacerbating systemic toxicities (Abstract LBA9005).

Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, and Thejus Jayakrishnan, MD, of the Cleveland Clinic Taussig Cancer Institute, discuss significant differences in the citrate cycle, a core pathway of cellular metabolism associated with colorectal cancer. Metabolomic differences impacted by environmental exposures (arginine biosynthesis and dietary red meat) were also noted, suggesting possible links with younger age of onset in this disease (Abstract 3510).

Allison Betof Warner, MD, PhD, of Stanford University Medical Center, and Adnan Khattak, MBBS, FRACP, PhD, of Australia’s Hollywood Private Hospital & Edith Cowan University, discuss the use of the mRNA-4157 vaccine in combination with pembrolizumab as adjuvant therapy for resected high-risk melanoma, which prolonged distant metastasis–free survival compared with pembrolizumab alone. These results provide further evidence that a personalized neoantigen approach is potentially beneficial (Abstract LBA9503).
