Abstract:
The objective of this study is to define the natural history of T1G3 bladder tumor not receiving intravesical Bacillus Calmette-Guerin (BCG) and to assess the diagnostic and therapeutic value of a second transurethral resection (Re-TUR) in these patients. Retrospective study on the natural history of 210 patients treated at two institutions for T1G3 bladder carcinoma without associated CIS. In no case was BCG administered; 79 (37.6%) received TUR alone, and 131 (62.4%) Re-TUR 4–6 weeks later; 23 (12.4%) underwent cystectomy for tumor progression.
