| Abstract |
PURPOSE
The purpose of this study was to compare the efficacy of curative emergency surgery for complicated colon cancer in terms of tumor recurrence and survival compared with that of elective surgery.
METHODS
A total of 238 primary surgeries for colon cancer were performed. All patients were deemed to have undergone a curative resection. Patients were classified into an emergency surgery group for complicated colon cancers (n=40) and an elective surgery group for uncomplicated colon cancers (n=198).
RESULTS
Emergency colonic cancers present at a more advanced stage (P=0.002). The postoperative mortality rate in the emergency group was significantly higher than it was in the elective group (15.0% vs. 2.5%, P= 0.004). There were differences between the two groups in tumor recurrence (32.5% vs. 13.1%, P=0.003), overall survival (52.5% vs.
71.7%, P=0.017), and disease-free survival (50.0% vs. 69.7%, P=0.016). However, after the patients were stratified according to tumor stage, no statistical differences were observed.
CONCLUSIONS
When compared with uncomplicated colon cancers, complicated colon cancers present at a more advanced stage with a higher postoperative mortality and an overall worse prognosis. However, the difference decreases when patients are stratified according to the tumor stage. The negative prognostic efficacy of emergency surgery for complicated colon cancers appears to be confined to the perioperative period. Despite the more advanced stage of tumors in patients undergoing emergency surgery, the aim of the surgeon should be to offer a curative resection for better survival, if possible. |
