My dad is 87, one year since diagnosis of advanced PC. starting psa 2790, numerous bone lesions all over and lymph nodes too.He's been on Firmagon monthly shot, reached lowest of 33 and now rising again. psa was 89 last month and this month 133. What would be the next step? He has no co-morbid conditions and is fairly active though weak. We have to meet the Oncologist next week to discuss options.
