You broke what Dr. Scholz calls the threshold, PSA < 0.1 . That is considered a good outcome. It seems to take 6 months to get to that point, which is a little over the 5 months. Still not too far off. It may be that the doctor added Chemo because your PSA was not falling fast enough after surgery. May be it is more appropriate to question why surgery if he was intended to give the triple treatment? It would have spared a lot of expense and negative physical effect. Put another way, if you have started off with triplet right from the get go, without surgery, would you have arrived at the same result, or e perhaps even sooner, say within 5 months? It bears thinking about.
Dont mind me. I am just another layman trying to make some sense.
