Abstract

Despite the good quality of treatment expected with optimized transurethral resection (TUR) and adjuvant Bacillus Galmette-Guérin (BCG) regimen, many high-risk non-muscle invasive bladder cancer (NMIBC) patients recur and progress. According to the EORTC Tables of risk, cases with a score of 10-17 and those with a score of 7-23 should be considered as being at high risk of recurrence and progression, respectively. AUA and NCCN consider all T1 stage tumors, high grade Ta and CIS at high risk of recurrence and progression. Long-term follow-up shows that T1, G3 patients treated with BCG will suffer from up to 45% and 17% rate of recurrence and progression, respectively. Consequently, EAU, AUA and NCCN Guidelines for bladder cancer recommend radical cystectomy as a first treatment option for those patients who failed after two cycles of adjuvant BCG. However, to date, there is no definitive evidence that in this special subgroup of patients an early radical cystectomy is better than any additional salvage strategy, in terms of oncologic outcome. On the other hand, it is well accepted that radical cystectomy is burdened with consistent reduction of overall post-operative quality of life. The reluctance of patient to accept (and of surgeon to recommend) this major extirpative surgery may explain the reduced disease-free survival rate, well documented when radical cystectomy has been extremely delayed. Defining the criteria for the selection of BCG-failure patients for whom any conservative procedure should be definitively abandoned in favor of a timely radical cystectomy has become of critical importance. Recently, clinical, laboratory and pathologic acquisitions allowed the development of more accurate predictive factors for tumor progression in NMIBC. Among these factors, clinical type of BCG-failure, morphology and tumor growth patterns, pathologic sub-staging and immunohistochemistry will play a paramount role in decision-making with these patients in routine practice.
