Incorrect Affiliations and Updated Supplement

In the Original Investigation titled “Association of AR-V7 on Circulating Tumor Cells as a Treatment-Specific Biomarker With Outcomes and Survival in Castration-Resistant Prostate Cancer” published online June 4, 2016,¹ an error occurred in the author affiliations, as well as in the online supplemental material. The affiliations “Epic Sciences, La Jolla, California” and “Body Imaging Service, Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, New York” were inverted, and table headers were added to eTable 1 in the Supplement. This article was corrected online.
