The 10-year outcomes from the RADAR phase 3 trial were recently published. The results showed that men with locally advanced prostate cancer who were treated with six months of androgen suppression therapy (ADT) and prostatic radiotherapy did not do as well as those who were treated with 18 months of ADT and radiation.
Time to PSA Recurrence Is A Surrogate Endpoint for Prostate Cancer Survival
In an analysis of the NRG Oncology clinical trial NRG-RTOG 9202 it was shown that the interval of time to biochemical reoccurrence (PSA only or BCR), or the time it takes for previously treated prostate cancer to return as indicated by a prostate-specific antigen (PSA) rise, could be used as a surrogate endpoint for survival for men with locally advanced prostate cancer.
