Wow. Too much for me to follow all the convolutions of this one.
Let me simply add, my G9 cT3 (by 3TMRI), was treated by IGRT and HT. I had about
a 40% chance of undetectable lymph node involvement, so we treated all of them to 50.4 Gy, then concentrated the rest on the prostate to 79.2 Gy. Then HT to hopefully starve out any baddies that were out there systemically.
While I recognize you don't want HT, it is a definite help for high risk cases treated by IGRT. It's no picnic, but what you have to keep in mind is those wretched Type 5 cells are rather easily metastatic. They're so distorted, they don't even remember being prostate cells anymore. So, doing something systemic is a pretty good idea since you can't know if those little dandelion seeds have landed elsewhere in your body. They're what the HT is intended to degrade/destroy over the cells very slow division cycles.
All the best in your decision making. It's complex, not easy, and can be a bit emotional.
Finally, as a fellow G9 5+4, let me welcome you to the G9 Crew. We have thread that's a gathering place for those facing this diagnosis, since it has some unique concerns. Here's a link to it. You'll find I've taken the liberty of placing your forum name on the roster in the least favorite chapter of the least favorite club no one would ever want to join!
