Apar Kishor Ganti, MD, on SCLC: Comparing Quality of Life With Once- and Twice-Daily Thoracic Radiotherapy
2022 ASCO Annual Meeting
Apar Kishor Ganti, MD, of the University of Nebraska Medical Center, discusses results from the CALGB 30610 study, which showed a similar clinical benefit for once- and twice-daily radiotherapy administered to patients with limited-stage small cell lung cancer. While both regimens were well tolerated, patients who received radiotherapy once daily had better quality-of-life scores at week 3 and slightly worse scores at week 12. Patients believed the once-daily regimen was more convenient (Abstract 8504).
Nancy Davidson, MD, of the Fred Hutchinson Cancer Research Center, reviews results from four abstracts about the importance of long-term follow-up in studies of adjuvant endocrine therapy for hormone receptor–positive breast cancer. Because the natural history of hormone receptor–positive breast cancer is long, an effort is underway to improve selection of patients by clinical parameters or biomarkers, refine the endocrine therapy background, and administer more effective combinations of endocrine therapy with other agents.
Maxwell Oluwole Akanbi, MD, PhD, of McLaren Regional Medical Center, discusses the study he conducted, using the SEER database, to evaluate the impact of lung cancer screening recommendations on low-dose CT scanning. The data suggest that guidelines from the U.S. Preventive Services Task Force led to a more rapid decline in the incidence of advanced disease in the United States, especially among minority populations (Abstract 10506).
Shilpa Gupta, MD, of the Cleveland Clinic Foundation, discusses an updated consensus definition for standard therapy and clinical trial eligibility for patients with metastatic urothelial cancer who are platinum-ineligible, criteria that are proposed to guide treatment recommendations for this population. This may be especially important now that the U.S. Food and Drug Administration has restricted the use of first-line pembrolizumab to those who are considered platinum-ineligible (Abstract 4577).
Eunice S. Wang, MD, of Roswell Park Comprehensive Cancer Center, discusses long-term phase II findings of a trial evaluating crenolanib plus chemotherapy in newly diagnosed adults with FLT3-mutant acute myeloid leukemia. The study showed a composite complete remission rate of 86%. With a median follow-up of 45 months, median overall survival has not been reached. A phase III trial is ongoing (Abstract 7007).
Martin McCabe, PhD, of the University of Manchester, discusses a phase III assessment of chemotherapy for patients with recurrent and primary refractory Ewing sarcoma. The trial, called rEECur, is the first study to provide comparative toxicity and survival data for the four most commonly used chemotherapy regimens in this disease. The analysis showed that high-dose ifosfamide is more effective in prolonging survival than topotecan plus cyclophosphamide (Abstract LBA2).
