ESMO 2018: Treatment of Asymptomatic or Mildly Symptomatic Chemotherapy-Naïve Patients with Bone-Predominant mCRPC
Munich, Germany (UroToday.com) Radium-223 is an alpha emitter which selectively treats bone metastases with alpha radiation1. In a recent GU ASCO oral presentation, a radium-223 pharmacodynamic study demonstrated that higher gamma emission is found in deep tumor containing regions of bone biopsies, compared with superficial regions, supporting the presumed mechanism of radium-2232.

ESMO 2018: Cabazitaxel vs Abiraterone or Enzalutamide in Poor Prognosis Metastatic Castration-Resistant Prostate Cancer Patients
Munich, Germany (UroToday.com) Cabazitaxel, abiraterone, and enzalutamide have demonstrated benefit in randomized controlled trials for patients with mCRPC. Abiraterone was shown to be effective in patients pre and post-chemotherapy in Cougar 301 and Cougar 3021,2. In patients who had not been treated with docetaxel, abiraterone significantly improved median overall survival compared with placebo (34.7 months vs 30.3 months, HR 0.81 (95% CI 0.70–0.93), p=0·0033). In patients who had progressed on docetaxel, overall survival with abiraterone was 14.8 months, compared with 10.9 months on placebo (HR 0.65, 95% CI 0.54 to 0.77; P<0.001).
