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).

Jennifer L. Crombie, MD, of Dana-Farber Cancer Institute, discusses the historically poor outcomes for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Her study examined real-world data on the use of novel therapies in this population and found that outcomes with second- and third-line regimens of polatuzumab vedotin-piiq plus bendamustine and rituximab and tafasitamab plus lenalidomide remain suboptimal, with worse outcomes particularly after chimeric antigen receptor T-cell therapy (Abstract 7552).

Amer Methqal Zeidan, MBBS, MHS, of Yale University and Yale Cancer Center, discusses phase III findings on the first-in-class telomerase inhibitor imetelstat, which was given to patients with heavily transfusion-dependent non-del(5q) lower-risk myelodysplastic syndromes that are resistant to erythropoiesis-stimulating agents. Imetelstat resulted in a significant and sustained red blood cell (RBC) transfusion independence in 40% of these heavily transfused patients. The response was also durable and accompanied by an impressive median hemoglobin rise of 3.6 g/dL, and seen in patients with and without ring sideroblasts. Importantly, reduced variant allele frequency was observed in the most commonly mutated myeloid genes which correlated with duration of transfusion independence and hemoglobin rise, therefore suggesting a disease-modifying potential of this agent (Abstract 7004).

Tycel J. Phillips, MD, of City of Hope National Medical Center, and Emanuele Zucca, MD, of the Oncology Institute of Southern Switzerland and the International Extranodal Lymphoma Study Group, discuss findings from the largest prospective study of patients with primary mediastinal B-cell lymphoma. The trial data support omitting radiotherapy in patients who achieve complete metabolic response after immunochemotherapy (Abstract LBA7505).

Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill, and Javier Cortes, MD, PhD, of the International Breast Cancer Center and Universidad Europea de Madrid, discuss phase II findings showing that one in three patients with HER2-positive early breast cancer may safely omit chemotherapy. Among the chemotherapy-free patients treated with trastuzumab and pertuzumab, the 3-year invasive disease–free survival was 98.8%, with no distant metastases (Abstract LBA506).

Christian Pfister, MD, PhD, of Rouen University Hospital, discusses phase III results from the VESPER trial, which showed that dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin provided a better overall survival rate at 5 years and improved disease-specific survival compared with gemcitabine as perioperative chemotherapy in patients with muscle-invasive bladder cancer (Abstract LBA4507).
