Bob, so sorry that you are joining us!!
It is difficult to comment on your diagnosis and treatment, since things are done so differently in different countries. Exactly what was your "partial cystectomy?" That is rarely done in the US, and then for certain rare types of bladder cancer, not TCC, since TCC puts the entire bladder lining at risk.
I would echo Alan's comments about radiation. IF at all possible, I would avoid it. (Please do remember that we are not physicians, so are speaking from what we have heard, not a medical training background.) Once radiation is used, it is very difficult for any other treatments to be used. I would strongly suggest aa trip to Bankgok or somewhere that has sophisticated physicians with really great training.
If you have read much of this Forum, you will notice that our motto is "get a second opinion!" It is too important to be sure that you are headed down the right path.

Best of luck to you
