OBJECTIVE: To report the 10-year follow-up of a study randomizing between instillations of bacillus Calmette-Guérin (BCG) and mitomycin-C (MMC) for treating high-risk and not muscle-invasive urinary bladder cancer to assess progression, the need for more aggressive treatment and survival (cancer-specific and overall), as many of the published studies comparing different treatments for disease that is not muscle-invasive have a short follow-up. PATIENTS AND METHODS: Between 1987 and 1992, 261 patients were included, they had frequently recurring Ta/T1G1-G2, T1G3 or primary Tis-dysplasia. The patients were randomized to treatment with either 40 mg of MMC or 120 mg of BCG (Danish strain 1331) given weekly for 6 weeks, then monthly up to a year and finally every third month for a further year. The 250 evaluable patients were followed using hospital files and national registers on causes of death. RESULTS: The median follow-up for survivors was 123 months. The disease progressed in 58 (23%) of the patients, 34 in the MMC group and 24 in the BCG group (P = 0.26). Of the 140 patients who died, 68 were in the BCG and 72 in the MMC group (log-rank P = 0.98), most (95, 68%) died from other causes. CONCLUSION: Based on the follow-up of the present patients it cannot be concluded that the drugs originally administered, MMC or BCG, differed in their effect on progression, need for subsequent treatment or survival. © 2007 The Authors.
