Mal, interesting question. Actually, the subject of PCa comes up fairly frequently in discussions as I have been quite open about my disease so guys seem comfortable asking about it. With one in six men getting it, most of my cohorts (who are in their 60's) are quite interested in the subject.
As I consider your question, I think my response is generally that I HAD PCa. Maybe that is because I have no SE's, am not dealing with any resultant issues and believe in my own little head that it is a past issue. However, when asked, "Am I cured?", I generally answer, "I hope so, but will never know for sure until they do my autopsy in 30 years". Then I tell them that I will have annual PSA tests that will be my indicator.
