Summary We prospectively studied random bladder biopsies of normal-looking mucosa in 1026 unselected patients with primary superficial papillary transitional-cell carcinoma of the bladder. In a univariate analysis, the risk for recurrent disease was only slightly higher in patients with an abnormal biopsy result, the 2-year actuarial risk for recurrent disease being 47.5% in these subjects vs 44.5% in patients with a normal biopsy result (P=0.09, log-rank test). However, after correction for other prognostic factors using the Cox proportional-hazards model, an abnormal biopsy result had no prognostic value additional to that of conventional histo-pathology of the tumour with regard to the risk for recurrent disease. Additional therapy after transurethral resection of the tumour (P〈0.001), tumour stage (P〈0.001), the number of bladder areas affected by tumour (P〈0.01) and tumour multiplicity (P=0.09) had significant prognostic value. We conclude that random biopsies of normal-looking mucosa during transurethral resection of superficial papillary bladder tumours are of little additional prognostic value with respect to the risk for recurrent disease.
