Locally recurrent colorectal cancer and hepatic metastases: Safety, feasibility, and outcomes after concomitant resection.

535 Background: The most effective management of locally recurrent colorectal cancer (CRC) is resection. This is also true for hepatic metastases (HM). Data remains limited, however, regarding concomitant resection of recurrent CRC and HM. The aims of this study were to determine the feasibility, safety and outcomes in terms of disease-free survival (DFS) and overall survival (OS) in patients undergoing concomitant resection of recurrent CRC with HM. Methods: All patients who underwent resection of recurrent CRC from 1/1995 to 1/2007 at Mayo Clinic, Rochester were reviewed (n=406). The study group consisted of patients who underwentconcomitant resection of locally recurrent CRC and hepatic resection for metastatic CRC (n= 45). Kaplan-Meier Survival was used to estimate DFS and OS. Results: The study group consisted of 27 men and 18 women. The median age was 59 years. Surgical management involved pelvic dissection in 43 patients and ileotransverse colectomy in two. 17 patients required resection of contigu...
