title: Therapy of superficial bladder carcinomas.
abstract: Treatment of superficial bladder carcinoma was derived by several large randomized trials. This group of cancers is stratified by differentiation grade and stage in three groups of different risk profiles (Ta G1-2 vs. T1 G1-2 vs. Tis/T1 G3). Standard therapy is fractionated transurethral resection (TUR). Adjuvant therapy after transurethral resection is not indicated in primary Ta G1-2 tumors because there is a low recurrence rate and no risk of tumor progression. The recurrence rate can be decreased up to 15% in recurrent Ta or T1 G1-2 tumors by intravesical therapy with mitomycin C (20 mg/instillation) or adriamycin (50 mg/instillation). Therapy should be limited to early (within 24 h post-TUR) and short-term treatment (4 x weekly, 5 x monthly). Alternatively, patients can be treated by intravesical BCG (strain Connaught or strain RIVM). Maintenance therapy is advantageous according to recurrence rate. Tumors with great malignant ability (Tis or T1 G3) will be treated initially with adjuvant BCG. Patients who fail are candidates for radical cystectomy within 3-6 months after initial diagnosis. There is no need - except in clinical trials - for the administration of unverified or not admitted drugs.
