I didn't want my question to get lost so I'm creating a new thread. I was just reading maldugs post re first post-op PSA and I have a question. He mentions that his post surgery PSA came in at 0.05 and his Urologist said that he may need to have follow-up radiation. I thought the post surgery psa should be <.1 to be considered normal. What are the factors that determine if radition is required as a follow-up protocol? Is it the psa and margins? What psa levels post surgery require follow-up treatment?
