Task: Answer Verification
Input (English): Question: Is less advanced disease at initiation of salvage androgen deprivation therapy associated with decreased mortality following biochemical failure post-salvage radiation therapy?
Answer: Less advanced disease at initiation of SADT is associated with decreased PCSM and OM following BF post-SRT; however, observation may be reasonable for patients with very long PSADTs. A PSADT <3 months prior to SADT initiation significantly predicts an increased risk of PCSM and OM in this patient demographic.
Output (English): yes
