Richard T. Penson, MD, and Don S. Dizon, MD, on Ovarian Cancer: SOLO3 Trial on Olaparib vs Chemotherapy in Relapsed Disease
2019 ASCO Annual Meeting
Don S. Dizon, MD, of the Lifespan Cancer Institute, and Richard T. Penson, MD, of Massachusetts General Hospital Cancer Center, discuss phase III study findings on the PARP inhibitor olaparib, which showed a significantly higher objective response rate vs nonplatinum chemotherapy for patients with ovarian cancer who relapsed, are platinum-sensitive, and have BRCA-mutant disease (Abstract 5506).
Justin F. Gainor, MD, of Massachusetts General Hospital, discusses updated findings from the ARROW study in which BLU-667, a selective RET inhibitor, demonstrated clinical activity and tolerability in patients with advanced RET fusion–positive non–small cell lung cancer (Abstract 9008).
Patricia A. Ganz, MD, of NRG Oncology and Jonsson Comprehensive Cancer Center at UCLA, discusses the NRG/NSABP phase III findings, which showed that partial-breast irradiation was more convenient and resulted in less fatigue but slightly poorer cosmesis at 36 months in patients who did not receive chemotherapy (Abstract 508).
Brian C. Baumann, MD, of Washington University School of Medicine, discusses study findings suggesting postoperative radiotherapy may be an option for patients with locally advanced bladder cancer after radical cystectomy who are unable or unwilling to use adjuvant chemotherapy (Abstract 4507).
Kamran A. Ahmed, MD, of the H. Lee Moffitt Cancer Center and Research Institute, reports on a trial in progress that is investigating whether treatment with atezolizumab plus hypofractionated radiation therapy will improve the objective response rate compared with atezolizumab alone in patients with recurrent, persistent, or metastatic cervical cancer (Abstract TPS5596).
William D. Tap, MD, of Memorial Sloan Kettering Cancer Center, discusses negative study findings on doxorubicin plus olaratumab vs doxorubicin plus placebo, which showed no difference in overall survival between the two treatments in patients with advanced soft-tissue sarcomas. The manufacturer is currently withdrawing olaratumab from the global market (Abstract LBA3).
