Description
Summary:INTRODUCTION AND OBJECTIVEMinimally invasive surgery represents an attractive surgical approach in radical cystectomy. However, its effect on the oncological results is still controversial due to the lack of definite analyses. The objective of this study is to evaluate the effect of the laparoscopic approach on cancer-specific mortality. MATERIAL AND METHODA retrospective cohort study of two groups of patients in a pT0-2pN0R0 stage, undergoing open radical cystectomy (ORC) (n=191) and laparoscopic radical cystectomy (LRC) (n=74). Using Cox regression, an analysis has been carried out to identify the predictor variables in the first place, and consequently, the independent predictor variables related to survival. RESULTS90.9% were males with a median age of 65years and a median follow-up period of 65.5 (IQR27.75-122) months. Patients with laparoscopic access presented a significantly higher ASA index (P=.0001), a longer time between TUR and cystectomy (P=.04), a lower rate of intraoperative transfusion (P=.0001), a lower pT stage (P=.002) and a lower incidence of infection associated with surgical wounds (P=.04). When analyzing the different risk factors associated with cancer-specific mortality, we only found the ORC approach (versus LRC) as an independent predictor of cancer-specific mortality (P=.007). Open approach to cystectomy multiplied the risk of mortality by 3.27. CONCLUSIONSIn our series, the laparoscopic approach does not represent a risk factor compared to the open approach in pT0-2N0R0 patients.
