Neeraj Agarwal, MD, and Thomas W. Flaig, MD, on Muscle-Invasive Bladder Cancer: Predicting Response to Neoadjuvant Chemotherapy
2019 ASCO Annual Meeting
Neeraj Agarwal, MD, of Huntsman Cancer Institute, University of Utah Health Care, and Thomas W. Flaig, MD, of the University of Colorado, discuss phase II findings on a novel predictive biomarker of response to the two accepted neoadjuvant regimens for muscle-invasive bladder cancer: methotrexate/vinblastine/doxorubicin/cisplatin and gemcitabine/cisplatin (Abstract 4506).
Hani M. Babiker, MD, of the The University of Arizona, discusses an emerging treatment that inhibits the mitotic spindle and disrupts tumor cell growth. The method has been approved by the FDA to treat some cancers and data show improved progression-free and overall survival (Abstracts 2055, 8551, e14658, e14668, e15653, e20069, e15766).
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).
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).
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).
Hope S. Rugo, MD, of the University of California, San Francisco, and Peter Schmid, MD, PhD, of Barts Cancer Institute, Queen Mary University of London, discuss ongoing trials of immunotherapy for early triple-negative breast cancer; immunotherapy in other disease subtypes such as estrogen receptor–positive and HER2-positive; and checkpoint inhibition in PD-L1–negative disease.
