Charles N. Landen, MD, on Newly Diagnosed Ovarian Cancer: BRCA Mutations, PD-L1 Expression, and Combination Chemoimmunotherapy
SGO 2021 Virtual Annual Meeting on Womens Cancer
Charles N. Landen, MD, of the University of Virginia, discusses results from the first clinical trial in ovarian cancer to demonstrate that neither a BRCA1/2 mutation nor a homologous recombination deficiency improves sensitivity to a therapeutic PD-L1 blockade in patients receiving atezolizumab vs placebo combined with carboplatin, paclitaxel, and bevacizumab for newly diagnosed disease (ID #10240).
Supriya Chopra, MD, of Tata Memorial Centre, discusses a final analysis of the phase III PARCER trial, which showed that image-guided intensity-modulated radiotherapy is superior to conventional radiotherapy in reducing bowel toxicity in women with cervical cancer. Acute diarrhea was also reduced, with no difference in disease-related outcomes (ID# 10224).
Alice P. Barr, MD, of the Carolinas Medical Center and Levine Cancer Institute, discusses results from a retrospective study, which showed that progression-free and overall survival appeared to be no different with open surgery and minimally invasive surgery for interval debulking after neoadjuvant chemotherapy in women with advanced epithelial ovarian cancer. Perioperative outcomes also seemed to be superior with minimally invasive surgery (ID #10209).
Emily Hinchcliff, MD, MPH, of The University of Texas MD Anderson Cancer Center, discusses phase II results of durvalumab (anti–PD-L1) and tremelimumab (anti–CTLA-4) administered in combination vs sequentially for the treatment of recurrent platinum-resistant non–clear cell ovarian cancer (ID #10240).
Shannon N. Westin, MD, of The University of Texas MD Anderson Cancer Center, discusses phase II results from the ENPAC trial, which showed the combination of enzalutamide, paclitaxel, and carboplatin yielded promising clinical outcomes in chemotherapy-naive advanced or recurrent endometrioid cancer (ID # 10244).
William H. Bradley, MD, of the Medical College of Wisconsin, discusses results from the SOLO-1 trial on maintenance olaparib after first-line platinum-based chemotherapy for patients with newly diagnosed advanced ovarian cancer and a BRCA mutation. Almost half of the patients treated with olaparib in the study were disease-free at 5 years, vs 20% of those treated with placebo (ID# 10224).
