No significant association was found between c-TURBT, LNI and STSM.Conclusion We found a low rate of achievement of pT0 stage at RC. An incomplete TURBT before RC represented a predictor of pT3-T4 stages, but no effect of a c-TURBT was shown on survival outcomes.

Abstract

Purpose To evaluate the role of a complete transurethral resection of bladder tumors (c-TURBT) on oncological outcomes after radical cystectomy ( RC) and its relationship with adverse pathological features.Methods We retrospectively analyzed data of 727 patients treated with RC and bilateral pelvic lymph node dissection at three tertiary referral centers. Possible c-TURBT was reported by the treating surgeon. Multivariable Cox regression analyses were used to assess the relationship of c-TURBT and survival outcomes after surgery in 1:1 propensity score-matched cohort adjusted for age and gender. Moreover, multivariable logistic regression (MVA) was built to predict the relationship between c-TURBT and pT3-T4 stages at RC, lymph node invasion (LNI) and positive soft tissue surgical margin (STSM).Results A total of 433 (60%) patients received a c-TURBT. 3.0% of patients with a c-TURBT achieved a pT0-pTa-pTis status vs. 2.0% of patients with incomplete TURBT. At multivariable Cox regression analyses, c-TURBT was not associated with survival outcomes. At MVA, incompleteness of TURBT was significantly associated with a pT3-T4 stage [odds ratio (OR) 8.04, 95% confidence interval (CI) 2.33-27.67, p = 0.001]. No significant association was found between c-TURBT, LNI and STSM.Conclusion We found a low rate of achievement of pT0 stage at RC. An incomplete TURBT before RC represented a predictor of pT3-T4 stages, but no effect of a c-TURBT was shown on survival outcomes. Given the current inadequacy of clinical staging strategies with more than 50% of extravesical disease being under-staged, our results could improve patients selection for NAC, driving the decision-making in doubtful cases.
