Georgina V. Long, MD, PhD, on Melanoma: Distant Metastasis–Free Survival With Adjuvant Pembrolizumab
2022 ASCO Annual Meeting
Georgina V. Long, MD, PhD, of the Melanoma Institute Australia, The University of Sydney, discusses phase III findings from the KEYNOTE-716 study. The trial showed that compared with placebo, adjuvant pembrolizumab significantly improved distant metastasis–free survival in patients with resected stage IIB and IIC melanoma. The findings also suggest a continued reduction in the risk of recurrence and a favorable benefit-risk profile (Abstract LBA9500).
Stephen M. Ansell, PhD, MD, of Mayo Clinic, discusses updated data from the ECHELON-1 trial, which showed that, when administered to patients with stage III or IV classical Hodgkin lymphoma, the combination of brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) vs doxorubicin, bleomycin, vinblastine, and dacarbazine resulted in a 41% reduction in the risk of death. These outcomes, says Dr. Ansell, confirm A+AVD as a preferred option for previously untreated disease (Abstract 7503).
Neal D. Shore, MD, of the Carolina Urologic Research Center, discusses his study findings, showing that germline genetic testing influenced care for patients with prostate cancer. Men whose genetic test was positive for a pathogenic germline variant received more recommendations for changes to follow-up and treatment, and for testing and counseling of relatives, than did patients with negative or uncertain test results (Abstract 10500).
Mairéad G. McNamara, PhD, MBBCh, of The Christie NHS Foundation Trust, discusses phase II findings of the NET-02 trial, which explored an unmet need in the second-line treatment of patients with progressive, poorly differentiated extrapulmonary neuroendocrine carcinoma. In the trial, the combination of liposomal irinotecan, fluorouracil, and folinic acid, but not docetaxel, met the primary endpoint of 6-month progression-free survival rate (Abstract 4005).
Paul G. Richardson, MD, of Dana-Farber Cancer Institute, discusses phase III findings from the DETERMINATION trial, which showed that, for patients with newly diagnosed multiple myeloma, lenalidomide, bortezomib, and dexamethasone (RVd) with or without autologous stem cell transplant (ASCT) and lenalidomide maintenance to disease progression resulted in the longest median progression-free survival reported for each approach, and a highly significant difference in progression-free survival in favor of early transplant. While overall response rates were similar, rates of MRD favored early transplant also, but toxicity was greater and quality of life was transiently but significantly diminished. No overall survival advantage has been observed to date (Abstract LBA4).
Sumanta K. Pal, MD, of City of Hope National Medical Center, discusses findings from the COSMIC-021 study, which showed that cabozantinib plus atezolizumab demonstrated encouraging clinical activity with manageable toxicity in patients with inoperable locally advanced or metastatic urothelial carcinoma. The combination was administered as first-line therapy in cisplatin-based chemotherapy–eligible and –ineligible patients and as second- or later-line treatment in those who received prior immune checkpoint inhibitors (Abstract 4504).
