Jack,
I too will be interested in the same question as I was DX'x 5 months ago and finishing the remaining 2 of 6-second group of BCG treatments. Not to make us statistics, I have read in differing abstracts staying recurrence free can be as high as 50%. Problem is, if it comes back then it 100% not to play with numbers. Still a lot of options should that happen. That being said, I have no clue what the stats are on grade and stage possibilities, I just no that RC is not always the next step. Repeating BCG, other therapies etc. The med community is even working on regenerated bladders.
