I completed #19 (out of 40) today. Had an interesting talk with my R-doc..When I questioned him about the 80Gy dose I was SURE he said was my treatment plan, he said no, that's not correct, you are getting 72 Gy, 1.8 Gy per treatment...I replied: "Then how did I get the 80Gy idea?" to which he replied "I don't know..."
So I asked him what would happen if we went to 80Gy and he said the risk of healthy tissue damage would be significantly increased without any corresponding increase in treatment effectiveness..
He also mentioned that the 72Gy dose was what the target area was getting. In order to achieve this dose, using the Rapid Arc machine, my overall body dose was only one third that which would be necessary with an older, indexing, 8-field IGRT machine...Does this make any difference I asked? He replied: We don't know yet, this machine has only been in use for 2 years..But common sense says reducing overall body exposure is a good thing...
He was a little concerned with my increasing urinary frequency and we decided that I would ingest the 16 ounces of water one hour before treatment instead of 1/2 hour to fill my bladder (during treatment ) a little more.
