Gemma,
I had a similar "CONVERSATION" with my one of my oncologists at the hospital i'm being treated by. And it is very frustrating that they firstly assume you know what they are talking about and secondly don't appreciate that you are sitting there terrified about what they are going to tell you so you don't hear half of what they are saying except for anything that relates to a time scale!
Anyway the other consultant oncologist I have seen was much better and took the time to explain all the in's and out's of what was happening with my treatment.
Anyway to help you here is what i was told, and others please correct me if I have made any mis-assumptions.
Curative intent - Only achievable if the tumor has not broken out of the prostate and usually treated by removing it and follow up HT and/or RT.
Otherwise for men like me treatment is to suppress the growth of the Cancer by HT together with chemo and/or RT.
Now from what I understand HT will only work to suppress the cancer for a certain number of years (each person is different) but by having up front chemo will extend that time. They say a year but research (STAMPEDE TRIAL) is still ongoing so that figure may change with more data. I have been told that I should get 5 years before HT stops working, but I take that with a pinch of salt as I'm pretty sure none of the specialists really know how my body will respond. So far everything has gone to plan.
I have yet to go down the road of finding out what will happen when my HT stops working but from what i've read on hear that's the start of another adventure
I can't say anything about RT as it's not on my treatment plan at present.
By the way if you can get your OH onto the Stampede Trial do so. I'm on it but only as a control sample i.e. I get no different treatment, but he will be monitored longer than usual which is also good.
Hope this helps
Andy
