However the criteria to abandon BCG therapy (i.e. BCG failure) in cases of recurrent but non-progressive UC can be vague. In this study we aim to assess a large cohort of CIS and pT1 UCB patients treated with intravesical IND-BCG and report on the outcomes according to the grade and stage of recurrences following IND-BCG. METHODS The data is from a single academic institution which is the only referral site for all BCG therapies for a large metropolitan area. Patients with initial diagnosis of pT1 and CIS received induction course of intravesical BCG. Post induction cystoscopy was carried out for all patients, and follow up was three monthly for the first two years, and at least biannually thereafter. RESULTS From 2001 to 2014, 261 patients received IND-BCG for pT1/CIS. Post BCG status were as follows: 132 (51%) pT0, 48 (18%) CIS, 31 (12%) pT1, 32 (12%) pTaHG and 10 (4%) pTaLG. Of the patients who were pT0 post-BCG, 74% remained disease free at a median of 8 mo. 19% developed high-grade recurrences including 4% with muscle invasive UC (MIUC) at a median of 16 mo (12-27) from diagnosis. Of patients with residual CIS, 60% responded to further BCG, with progression to invasive disease in 13%. Of residual pTaHG patients, 53% became pT0 and 9% eventually had cystectomy at 32.4 mo for disease progression to CIS or =pT1. 10 patients had pTa-LG recurrence and one required cystectomy. Only 36% of residual pT1 patients became pT0 with 29% developing invasive disease. 39% of pT1 compared to 17% of the CIS required cystectomy at a median of 17.5 mo (p=0.036). pT0 rates were significantly higher for CIS patients compared to pT1 (60% vs. 36%, 0.047), but similar between CIS and pTaHG. CONCLUSIONS Non-invasive recurrence of high grade UC following BCG may respond to further intravesical therapy however response is less likely in recurrent pT1 UC.
