Short-term outcome and survival after multiorgan resection for locally advanced colo-rectal cancer. Identification of risk factors

Abstract

INTRODUCTION: Although multi-organ resections (MOR) are recommended by international guidelines for advanced colo- rectal cancer, the literature shows that the morbidity and mortality that accompanies these complex interventions limits the number of patients receiving this treatment.
The purpose of our study was to analyse the immediate and remote results obtained after MOR and to identify poten- tial factors that might influence the outcome.

MATERIAL AND METHOD: Our study is a retrospective cohort which included patients surgically treated in our service for locally advanced colorectal cancer. We excluded patients with hepatic metastatic tumors and those who needed pelvic exenteration. Between 2006 and 2010, in our service, have been treated with MOR 146 patients, 107 being includ- ed in our study. We analysed morbidity, mortality and survival after MOR and the factors that could have influenced the postoperative course.

RESULTS: Identified risk factors that negatively influenced the postoperative outcome were: diabetes, personal neoplastic pathologies, associated cardiovascular disease, history of major surgeries, intraoperative blood loss, number of resected organs. Survival was negatively influenced by positive resection margins, the presence of lymph node metastases and the presence of complications in the postoperative period.

CONCLUSIONS: The data of this study support the indication for routine MOR for patients diagnosed with locally advanced colorectal cancer with the condition that R0 resection margins are achieved.
All mentioned above underline the importance of the experience that the surgical team has in this type of surgeries, in order to achieve optimum results. This experience must concern the preoperative management, surgical technique and postoperative care.
