Long-term post-intercourse prophylaxis with ciprofloxacin proved to be equally effective as daily prophylaxis, and the major advantage of the former therapy was use of only a third of the amount of drug consumed in daily prophylaxis.

A prospective randomized trial on 94 eligible patients evaluated and compared the efficacy of adjuvant intravesical epirubicin and bacillus Calmette-Guérin (BCG) after complete resection of multifocal superficial bladder cancer. BCG treatment schedule consisted of an induction 6-week course of instillations (150 mg Pasteur BCG per instillation) and single maintenance doses to patients who remained free of recurrences at follow-up examinations for a total treatment period of 2 years. These initial responders received additionally a separate 4-week course of therapy 6 months after the start of treatment. Chemoprophylaxis included an early (on the second postoperative day) instillation followed by 4 weekly treatments with epirubicin (50 mg per instillation) and then by 10 monthly treatments for the initial responders during the first year of follow-up and at every follow-up examination for a total treatment period of 2 years. The overall treatment results did not differ significantly between the 2 arms (54% of patients of the epirubicin group remained free of recurrences compared to 65% of those treated with BCG) for an identical mean follow-up of 35.1 months. However, a significant benefit in favour of BCG when compared with epirubicin was shown in patients who had stage T1 and grade 3 tumours and in terms of relative risk of recurrences, disease-free interval and recurrence rate per 100 patient-months. Both drugs were proved to be safe with manageable toxicity.

A prospective, randomized trial was conducted to evaluate and compare the effects of modified adjuvant intravesical bacillus Calmette-Guerin (BCG) and epirubicin regimens in patients with superficial bladder cancer. One hundred thirty-two individuals with recurrent and/or multiple neoplasms, i.e. at high risk for tumour recurrence and progression, were enrolled. After complete transurethral resection of their tumours, the patients received a 6-week course of BCG instillations or an early 4-week course of epirubicin instillations as their initial therapy. Those with stage Ta and grade 1 neoplasms who remained free of recurrences received maintenance therapy consisting of single quarterly instillations. However, for those with stage T1 cancer of any grade or stage Ta of grade 2 or 3 neoplasms who also remained free of recurrences, the treatment schedules were modified: they received, instead of single maintenance doses, 3 weekly instillations of epirubicin at months 3 and 6 of follow-up, or a 3-week course of BCG at month 6 of follow-up. The recurrence-free rates did not differ significantly between the two study groups (44% for epirubicin versus 55% for BCG), for an identical median follow-up of 43 months. However, in terms of relative risk of recurrences, disease-free intervals and recurrence rate per 100 patient-months, a significant benefit in favour of BCG when compared with epirubicin was demonstrated in patients who had stage T1 or grade 3 neoplasms.
