Howard I. Scher, MD, of Memorial Sloan Kettering Cancer Center, discusses circulating tumor cell number as a transitional surrogate endpoint for survival in phase II trials on metastatic castration-resistant prostate cancer (Abstract 143).
Nicholas J. van As, MD, of The Royal Marsden NHS Foundation Trust, discusses an analysis of acute toxicity in the PACE-B study, which compared stereotactic body radiotherapy with conventionally fractionated or moderately hypofractionated external-beam radiotherapy for localized prostate cancer (Abstract 1).
Rana R. McKay, MD, of the University of California, San Diego, discusses phase II study findings on atezolizumab and bevacizumab in non–clear cell renal cell carcinoma and clear cell renal cell carcinoma with sarcomatoid differentiation (Abstract 548).
Brian I. Rini, MD, of the Cleveland Clinic Taussig Cancer Institute, discusses phase III findings on a comparison of tivozanib and sorafenib in patients with refractory advanced renal cell carcinoma (Abstract 541).
Craig R. Nichols, MD, of the Testicular Cancer Commons and the SWOG Group Chair's Office, discusses the superior outcomes obtained at high-volume centers, the impracticality of referring all patients to such centers, and the international efforts to develop virtual collaborations on salvage management and post-chemotherapy surgery.
Laurence Albiges, MD, PhD, of Gustave Roussy, discusses findings on the safety and efficacy of nivolumab used in a “real world” prospective study on metastatic renal cell carcinoma (mRCC). This research was conducted after nivolumab was approved for the treatment of mRCC following failure of one or two tyrosine kinase inhibitors (Abstract 542).
