Multicenter external validation of the radical cystectomy pentafecta in a European cohort of patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion for bladder cancer

Objective To perform an external validation of this RC-pentafecta. Method Between January 2014 and December 2019, 104 consecutive patients who underwent RARC with ICUD within 6 urological centers were analyzed retrospectively. Patients who simultaneously demonstrated negative soft tissue surgical margins (STSMs), a lymph node (LN) yield >= 16, absence of major (Clavien-Dindo grade III-V) 90-day postoperative complications, absence of UD-related long-term sequelae, and absence of 12-month clinical recurrence were considered to have achieved RC-pentafecta. A multivariable logistic regression model was used to measure predictors for achieving RC-pentafecta. We analyzed the influence of this RC-pentafecta on survival, and the impact ofthe surgical experience. Results Since 2014, 104 patients who had completed at least 12 months of follow-up were included. Over a mean follow-up of 18 months, a LN yield >= 16, negative STSMs, absence of major complications at 90 days, and absence of UD-related surgical sequelae and clinical recurrence at <= 12 months were observed in 56%, 96%, 85%, 81%, and 91% of patients, respectively, resulting in a RC-pentafecta rate of 39.4%. Multivariate analysis showed that age was an independent predictor of pentafecta achievement (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.90. 0.99; p = 0.04). The surgeon experience had an impact on the validation of the criteria. Conclusion This study confirmed that the RC-pentafecta is reproducible and could be externally used for the outcome assessment after RARC with ICUD. Therefore, the RC-pentafecta could be a useful tool to assess surgical success and its impact on different outcomes.

Automated summary

The study confirmed that RC-pentafecta can be used to evaluate the surgical outcomes of RARC patients, with age being an independent predictor of pentafecta achievement and surgeon experience impacting the validation of the criteria.
