Abstract

Immunotherapy with Bacillus Calmette-Guérin (BCG) is the most efficacious treatment for high-risk bladder cancer (BC) (Ta/T1 or carcinoma in situ) to reduce the risk of recurrence. Our aim was to evaluate whether hypertension and diabetes influence the outcome of patients with noninvasive BC treated with BCG instillations.In order to collect homogeneous data, we considered as "hypertensive" only those patients who had previous diagnosed hypertension and a history of taking medical therapy with antihypertensive drugs (AHT), and as "diabetic" only those prescribed oral antidiabetics or insulin (ADT).We analyzed 343 high-risk BC patients undergoing BCG (1995-2010) with a median follow-up of 116 months (range 48-238). The distribution of various kinds of AHT and antidiabetic drugs was homogeneous, with no significant differences (p > 0.05).In both univariate and multivariate analyses, the only statistically significant parameter prognostic for recurrence after BCG treatment was AHT. Recurrence-free survival curves showed a significant correlation with AHT (p = 0.0168, hazards ratio [HR] 1.45, 95% confidence interval [CI] 1.0692-1.9619); there was no correlation (p = 0.9040) with ADT (HR 0.9750, 95% CI 0.6457-1.4721).
