The Role of Tumor-Free Status in Repeat Resection Before Intravesical Bacillus Calmette-Guerin for High Grade Ta, T1 and CIS Bladder Cancer

Tumor-free status at repeat transurethral bladder tumor resection improves the bacillus Calmette-Guerin response rate and delays tumor recurrence. During followup recurrence in residual tumor-free patients develop more likely as low grade lesions than in patients with residual tumor at repeat transurethral bladder tumor resection.
