You are asking many good questions that you ought to ask his doctor. I can only guess at what he has in mind from what you are telling me. I have never heard of radiation being used just to reduce the size of a prostate (My prostate shrank from 55 cc to 20 cc after radiation). De-bulking using radiation will also reduce the size of the prostate, but its main purpose is to reduce the size of tumors. If the tumor has consumed much of his prostate, it amounts to the same thing. Typical radiation doses for accomplishing that may be avout 80 Gy in 40 treatments, 60 Gy in 30 treatments, or 40 Gy in 5 treatments. If he is doing 13 treatments, he may be planning on delivering about
52 Gy. HT will reduce the prostate size within a few months.
Yes, they will monitor progression radiologically (bone scans, CTs, etc.) and with other biochemical markers (e.g., bone alkaline phosphatase).
