Abstract The preliminary results of a multi-institutional prospective randomized study of the prophylaxis of superficial bladder cancer using epirubicin (protocol NUORG SBT-003) are reported. The subjects were 129 patients with untreated superficial bladder cancer (≦T1b, ≦G2) who were randomized into 2 groups: a transurethral resection (TUR)-alone group (63 patients) and a TUR+intravesical epirubicin (20 mg/40 ml, 30 times/2 years) group (66 patients). The nonrecurrence rate observed in the epirubicin group was significantly higher than that seen in the control group. To unify the pathological diagnosis, a central pathology laboratory (CPL) was set up for extramural review. The correspondence of the pathological diagnosis of TUR-Bt specimens between the CPL and the local pathology laboratory (LPL) was 70.5% in grading and 51.9% in staging. There was a tendency for overdiagnosis by the LPL for both the grade and the stage of tumors. However, differing interpretations by pathologists seem to exert little influence on the nonrecurrence rate at interim analysis. Further observation will be necessary to clarify the prophylactic efficacy of low-dose, long-term periodic intravesical epirubicin instillation and the influence of the disagreement in pathological findings between the CPL and the LPL on the analysis of the results.
