Risk group stratification to predict recurrence after transurethral resection in Japanese patients with stage Ta and T1 bladder tumours: validation study on the European Association of Urology guidelines

Abstract

• This is the first report on the ECOG PS as a potentially useful predictor for bladder tumour recurrence. • The risk group stratification of the EAU guidelines for recurrence might not be applicable to Japanese patients with Ta and T1 bladder tumours, but the subgroup classification of intermediate risk could be appropriate.
