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).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Filippo Gustavo Dall’Olio, MD, of Institut Gustave Roussy, discuss circulating tumor DNA tumor fraction, and its link to survival in patients with advanced non–small cell lung cancer (NSCLC) treated with maintenance durvalumab in the UNICANCER SAFIR02-Lung/IFCT1301 trial. Tumor fraction was positive in 16% of patients randomly assigned to receive durvalumab in the study. This population seems to have a limited benefit from maintenance durvalumab after induction chemotherapy (Abstract 2516).

Nirav N. Shah, MD, of the Medical College of Wisconsin, discusses phase II results showing that split-dose R-CHOP offers older patients with diffuse large B-cell lymphoma (DLBCL) an equivalent dose intensity as R-CHOP-21 through a fractionated dosing schedule, improving tolerability. At the end of treatment for these older patients, a complete response rate of 71% was comparable to outcomes with R-CHOP in younger patients with the disease (Abstract 7554).

Rana R. McKay, MD, of the University of California, San Diego, and Toni K. Choueiri, MD, of Dana-Farber Cancer Institute and Harvard Medical School, discuss results from the phase III CONTACT-03 study, showing that, for patients with metastatic renal cell carcinoma (RCC), adding the PD-L1 inhibitor atezolizumab to cabozantinib did not improve clinical outcomes compared with treatment with cabozantinib alone. In addition, higher toxicities were observed in the combination arm (Abstract LBA4500).

Alberto Bossi, MD, of Institut Gustave Roussy, discusses phase III findings showing that combining prostate radiotherapy with systemic treatment did not improve overall survival in men with de novo metastatic castration-sensitive prostate cancer and low metastatic burden. However, best outcomes (radiographic progression–free-survival and overall survival) were observed in men receiving the standard of care plus abiraterone acetate plus prednisone with radiotherapy (Abstract LBA5000).

Lisa M. DeAngelis, MD, and Ingo K. Mellinghoff, MD, both of Memorial Sloan Kettering Cancer Center, discuss findings from the INDIGO trial showing that the IDH1/2 inhibitor vorasidenib improves progression-free survival for patients with residual or recurrent grade 2 glioma with an IDH1/2 mutation. These data demonstrate the clinical benefit of vorasidenib in this patient population for whom chemotherapy and radiotherapy are being delayed.
