At the ASCO GU meeting in January, Dr Thomas Beer presented the initial data for the PREVAIL trial, which explored enzalutamide (Xtandi) in castrate resistant prostate cancer (CRPC) prior to chemotherapy. Reactions to the data were mixed with many analysts, perhaps naively, focusing on the significant temporal survival benefit (2 months) rather than the 29% hazard ratio, which demonstrates the magnitude in the reduction in the risk of death over the control arm.

This weekend at the American Urological Association (AUA) meeting in Orlando, Dr Christopher Evans (UC Davis), presented the updated data, including the survival curves and a subset analysis for visceral and non-visceral disease. He focused on the clinical benefits that were clinically meaningful to the urology audience.

I have to say that the data shown was both compelling and impressive to me.
