Recurrence and progression in stage T1G3 bladder tumour with intravesical bacille Calmette-Guérin (Danish 1331 strain).
OBJECTIVE
To report recurrence and progression rates in patients with T1G3 superficial bladder carcinoma treated with intravesical bacille Calmette-Guérin (BCG, Danish 1331 strain) after complete transurethral resection.


METHODS
Data from the records of 111 patients with T1G3 bladder carcinoma treated between January 1991 and December 1999 were analysed for recurrence, progression, salvage therapy and survival.


RESULTS
Of the 111 patients with T1G3 bladder tumours, 69 had intravesical BCG therapy, 20 radical cystectomy and 22 only transurethral resection (TUR). Of the 69 patients receiving BCG therapy 37 (54%) had no recurrence, and 24 (35%) had a recurrence that was not muscle-invasive (Ta/T1) and were treated with TUR only. The remaining eight (12%) progressed to muscle invasion and had salvage cystectomy. During the follow-up six patients died, four from disease and three from other causes, while the remaining 63 are alive and well. Of the other 42 patients, 15 are alive after radical cystectomy and 18 after TUR.


CONCLUSIONS
This series further confirms the benefits of intravesical BCG (Danish 1331) in an adjuvant setting; furthermore, this treatment facilitates bladder preservation by reducing recurrences and delaying the progression in many patients.
