Abstract

Aim:To evaluate the short-term oncologic outcomes of curative resection for left-sided colon cancer obstruction following by stent insertionMethod:Between March 2005 and July 2008, 722 patients underwent surgical resection for colorectal cancer at St. Mary's Hospital, Kangnam. We include stage II, III left-sided colon cancer patients who underwent curative resection. The clinicopathologic variables and survival rate were compared between three groups. The median follow-up period was 25 months.Results:In our study, T stage was statistically different between the NO and PO + S group (P = 0.037). And neural invasion was statistically different between the PO and S group (P = 0.048). Overall survival rate of between three group showed no statistically significant differences (NO vs PO + S; P = 0.191, NO vs S; P = 0.110, PO vs S; P = 0.478). Disease free survival rates also showed no differences between three groups (NO vs PO + S; P = 0.352, NO vs S; P = 0.094, PO vs S; P = 0.182).Conclusions:Stent insertion itself does not compromised the survival of patients with obstructive left-sided colon cancer. A further large-scaledprospective study and long term follow up is necessary to evaluate the oncologic safety of stent insertion.
