Tony, my Doc wasn't surprise when he found out that I had a recurrence and he told me that about 80% of patients have had a recurrence but he was surprised why my other DOC who did the first TURB didn't put me on BCG , he thought it was possible because I had ta noninvasive tumor ,so after my second TURB done he put me on BCG+INTRONE treatment 7 courses ,then BCG alone 6 courses ,I had no reaction for the first 7 but I had very bad reaction for BCG alone and the DOC said it is good sign to have reaction that mean the medication is work !!
I don't know ?
any way they recommend to use the combination BCG+INTRON if you have a recurrence .I can give you a web about that if you want .
