We reviewed our results with 86 patients who had a pretreatment history of a stage T1 tumor. All patients were treated with transurethral resection of all visible tumor followed by intravesical bacillus Calmette-Guerin (BCG) and many patients received additional maintenance therapy. Local recurrences were treated with repeat transurethral resection followed by additional BCG. Median followup was 59 months, with a range of 9 to 149 months. Overall, 78 of 86 patients (91%) were free of tumor recurrence with BCG therapy. This result includes 69% of the patients who responded to the initial transurethral resection and intravesical BCG, and 22% who ceased having tumors after additional treatments for local recurrences. Only 7% of the patients had progression to stage T2 tumors after BCG therapy. Grade of the stage T1 tumor, concurrent carcinoma in situ and tumor multiplicity before BCG did not predict tumor recurrence or progression. Of patients with recurrences after BCG therapy, those with stage T1 tumors had a higher rate of progression compared to those with stage Ta tumors but the difference was not statistically significant (p = 0.086). These data clearly support the efficacy of transurethral resection plus intravesical BCG immunotherapy in the treatment of stage T1 tumors as well as in the prevention of disease progression.
