BACKGROUND The rationale for combining anticancer drugs has not been applied consistently to use of intravesical agents for treatment of superficial bladder cancer, for which immunotherapeutic BCG and chemotherapeutic mitomycin seem to be a potentially effective combination. We aimed to do a prospective, randomised comparison of BCG alone with that of sequential BCG and electromotive mitomycin in patients with stage pT1 bladder cancer. METHODS After transurethral resection and multiple biopsies, 212 patients with stage pT1 bladder cancer were randomly assigned to: 81 mg BCG infused over 120 min once a week for 6 weeks (n=105); or to 81 mg BCG infused over 120 min once a week for 2 weeks, followed by 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) once a week as one cycle for three cycles (n=107). Complete responders underwent maintenance treatment: those assigned BCG alone had one infusion of 81 mg BCG once a month for 10 months, and those assigned BCG and mitomycin had 40 mg electromotive mitomycin once a month for 2 months, followed by 81 mg BCG once a month as one cycle for three cycles. The primary endpoint was disease-free interval; secondary endpoints were time to progression; overall survival; and disease-specific survival. Analyses were done by intention to treat. This trial has been submitted for registration at the US National Cancer Institute website . FINDINGS Median follow-up was 88 months (IQR 63-110). Patients assigned sequential BCG and electromotive mitomycin had higher disease-free interval than did those assigned BCG alone (69 months [95% CI 55-86] vs 21 months [15-54]; difference between groups 48 months [42-54], log-rank p=0.0012). Patients assigned sequential BCG and electromotive mitomycin also had lower recurrence (41.9% [32.7-51.5] vs 57.9% [48.7-67.5]; difference between groups 16.0% [2.7-29.3], log-rank p=0.0012); progression (9.3% [3.8-14.8] vs 21.9% [17.9-25.9]; difference between groups 12.6% [3.0-22.2], log-rank p=0.004); overall mortality (21.5% [13.5-29.5] vs 32.4% [23.4-41.4], difference between groups 10.9% [0.6-21.2], log-rank p=0.045); and disease-specific mortality (5.6% [1.2-10.0] vs 16.2% [6.1-23.3], difference between groups 10.6% [2.5-18.7], log-rank p=0.01). Side-effects were mainly localised to the bladder. INTERPRETATION BCG-induced inflammation might increase the permeability of the bladder mucosa such that mitomycin can reach the target tissue more easily and exert its anticancer effect.

Peyronies disease continues to be a fascinating topic for urologists, and two papers in this section, one from Rome and one from Los Angeles, describe new insights into this disease.

PURPOSE A proportion of patients with detrusor hyperreflexia who are unresponsive to oral oxybutynin often benefit from intravesical oxybutynin instillation. To our knowledge the precise mode of action of this method is obscure. MATERIALS AND METHODS In 12 patients with detrusor hyperreflexia who were previously unresponsive to oral and intravesical passive diffusion of 5 mg. oxybutynin we administered 5 mg. oxybutynin orally as well as increased doses of 15 mg. oxybutynin intravesically with passive diffusion and with 15 mA. associated electric current. Each administration mode per patient was associated with an 8-hour urodynamic monitoring session during which oxybutynin and N-desethyl oxybutynin plasma levels, and intravesical oxybutynin uptake were measured. RESULTS A dose of 5 mg. oxybutynin orally induced no urodynamic improvement with an area under the plasma concentration time curve of combined N-desethyl oxybutynin plus oxybutynin of 16,297 ng./8 hours and an area under the curve ratio of N-desethyl oxybutynin-to-oxybutynin of 11:1. Passive diffusion oxybutynin resulted in 12 mg. oxybutynin intravesical uptake and significant improvement in 3 of 8 urodynamic measurements, although the area under the curve of combined N-desethyl oxybutynin plus oxybutynin was only 2,123 ng./8 hours and the N-desethyl oxybutynin-to-oxybutynin ratio was 1.1:1.0. Electromotive administration of oxybutynin resulted in almost complete intravesical uptake of the 15 mg. dose, significant improvement in all 8 urodynamic measurements and an increased oxybutynin level versus oral and passive diffusion, although the area under the curve of combined N-desethyl oxybutynin plus oxybutynin was 4,574 ng./8 hours and the N-desethyl oxybutynin-to-oxybutynin ratio was inverted at 1.0:1.4. The oral dose of 5 mg. oxybutynin caused anticholinergic side effects in 8 of the 12 patients. Neither intravesical passive diffusion nor electromotive administration caused side effects with an uptake of 12 and 15 mg., respectively. CONCLUSIONS A large proportion of intravesical oxybutynin is sequestered, probably in the urothelium. Intravesical oxybutynin administration confers therapeutic benefits via localized direct action within the bladder wall.

We report a rare case of a retroperitoneal inflammatory variant of malignant fibrous histiocytoma (MFH) involving both kidneys. The best treatment for MFHs is surgery with radical excision of the tumor. In this case the need to save at least one kidney meant tumorectomy was incomplete. The patient underwent adjuvant chemotherapy and 4 years later survives in a fairly good condition.

4539 Background: Intravesical bacillus Calmette-Guèrin (BCG) and mitomycin C (MMC) are a theoretically attractive combination for the treatment of high risk superficial bladder cancer. We conducted a prospective, controlled study comparing BCG with sequential BCG + electromotive delivery MMC in patients with T1 bladder cancer. METHODS Following transurethral resection and multiple biopsies we randomized 175 patients with T1 bladder cancer into 2 groups. Group I received BCG 81 mg; 6 weekly instillations. Group II received sequential BCG and electromotive (intravesical electric current; 20 mA for 30 min.) MMC at weekly intervals thus: (BCG, BCG, MMC) x 3, totaling 6 BCG and 3 MMC instillations. Non responders received repeat courses at 3 months. All complete responders underwent maintenance regimens of monthly instillations. Group I: 10 BCG treatments. Group II: (MMC, MMC, BCG) x 3, treatments. RESULTS Group I vs Group II: median (IQR or 95% CI). Follow up (months): 64 (38-82) vs 71 (49-87); p = 0.054 Recurrence: 47% (36-58) vs 28% (19-39); p = 0.013 Months to Recurrence: 11 (6-19) vs 20 (16-33); p = 0.001 Progression: 20% (12-30) vs 14% (7-22); p = 0.312 Months to Progression: 17 (10-21) vs 46 (21-58); p = 0.002 % 5-years mortality by any cause: 11.6 (5.7-20.3) vs 4.5 (1.2-11.1); p = 0.099 % 5-years mortality by bladder cancer: 9.3 (4.1-17.5) vs 1.1 (0.02-6.1); p = 0.017 Side effects were numerous but mainly localized to the bladder. There were no treatment related deaths nor episodes of serious illness nor bladder contractures. CONCLUSIONS Intravesical sequential BCG/electromotive MMC is superior to BCG alone in the treatment of high risk bladder cancer. [Table: see text].
