MP32-12 RADICAL CYSTECTOMY PENTAFECTA: A PROPOSAL FOR STANDARDIZATION OF OUTCOMES REPORTING FOLLOWING ROBOT ASSISTED RADICAL CYSTECTOMY

INTRODUCTION AND OBJECTIVES:To propose a standardisable composite method for reporting outcomes of radical cystectomy (RC) that incorporates both peri-operative morbidity and oncologic adequacy.METHODS:From July 2010 through December 2017, 277 consecutive patients who underwent robotic radical cystectomy (RRC) for bladder cancer at our institution were prospectively analysed. IRB approval was obtained (HS-01B014). Patients who simultaneously demonstrated negative soft tissue surgical margins, =/> 16 lymph node yield, absence of major (Clavien-Dindo grade III-IV) complications at 90 days, absence of urinary diversion (UD) related long-term sequelae and absence of clinical recurrence at =/< 12 mo. were considered as having achieved the RC-pentafecta. We created a multivariable logistic regression model using age, ASA score, type of UD, NACH, pT and pN stage as covariates to measure independent factors for achieving RC-pentafecta. The internal validity of the prediction model was assessed by 1,000 bootstrap ...
