Abstract

Eighteen consecutive patients who underwent rectal resection following preoperative chemotherapy for cStage Ⅳ rectal cancer at our institute, between 2009 and 2014, were retrospectively assessed. Preoperative chemotherapy with mFOLFOX6, SOX, XELOX, and other anticancer agents was administered to 8, 5, 3, and 2 patients, respectively. Combined molecular targeted therapy was administered to 12 patients. The response evaluation showed that an antitumor effect was observed in 10 and 8 patients with local tumors who achieved a partial response (PR) and stable disease (SD), respectively, and in 9 and 9 patients with distant metastases who achieved a PR and SD, respectively. The operative procedures included high/low anterior resection (n=12), intersphincteric resection (n=2), and abdominoperineal resection/Hartmann's operation (n=4). An ileostomy was performed in 6 patients before chemotherapy. Postoperative complications occurred in 6 patients. Two patients with an ileostomy had anastomotic insufficiency, but recovered without reoperation. There was no significant difference in overall survival (p=0.382) when these patients were compared with 45 cStage Ⅳ rectal cancer patients who underwent surgery without preoperative chemotherapy. However, the rate of curability B was higher in patients who received preoperative chemotherapy (44.4%) compared to those who did not (26.7%). The results of this study are inconclusive and have not determined whether preoperative chemotherapy results in better long-term survival for cStage Ⅳ rectal cancer patients. However, preoperative chemotherapy might contribute to higher operative curability.
