目的 探討新輔助化學療法（化療）對結直腸癌手術患者炎癥因子水平的影響。 方法 回顧2008年1月－2009年12月診斷為結直腸癌的487例患者的臨床資料，剔除不符合研究條件者后，共390例，以是否接受過新輔助化療分為術前化療組（化療組）156例與對照組234例進行研究。分別比較兩組在入院時、術前、術后的炎癥因子水平。 結果 入院時兩組外周血白細胞、C反應蛋白（CRP）、纖維蛋白原、血清淀粉樣蛋白水平差異均無統計學意義（P＞0.05）；術后化療組CRP水平[（64.09 ± 60.24）mg/L]低于對照組[（87.80 ± 61.54）mg/L]，差異有統計學意義（P＜0.05）；其余炎癥因子組間差異無統計學意義（P＞0.05）。 結論 新輔助化療不會刺激機體產生免疫反應，且有一定的安全性。
Objective To explore the effectiveness of neoadjuvant chemotherapy on postoperative risk of colorectal cancer by use of estimation of physiologic ability and surgical stress （E-PASS）. Methods A total of 161 patients with colorectal cancer according to the inclusion criteria from January 2009 to December 2009 in West China Hospital of Sichuan University were analyzed retrospectively，who were assigned to neoadjuvant chemotherapy group （NC group, 78 patients） and non-NC group （83 patients）. The postoperative risk of each group was assessed by the E-PASS scale including preoperative risk score （PRS），surgical stress score （SSS），and comprehensive risk score （CRS）. Results The baseline of two groups had no significant difference （P＞0.05）. The postoperative complication incidence of two groups had no significant difference either （P＞0.05）， which was 10.26% （8/78） in the NC group，and 7.23% （6/83） in the non-NC group. The PRS was 78.42 in the NC group and 83.42 in the non-NC group （P=0.497）. The SSS was 80.77 in the NC group and 81.22 in the non-NC group （P=0.951）. The CRS was 80.74 in the NC group and 81.24 in the non-NC group （P=0.976）. The accuracy of the postoperative risk assessment was 70 cases and 78 cases in the NC group and non-NC group，respectively. There was no significant difference of accuracy between two groups （P=0.325）. Conclusions Neoadjuvant chemotherapy does not increase the risk of patients with colorectal cancer after operation，and the results suggest that E-PASS scale can provide a more accurate assessment of neoadjuvant chemotherapy in patients with surgical risk.
Objective To compare the short-term outcomes between laparoscopic surgery and open surgery with fast-track (FT) in patients with colorectal cancer. Methods Between February 2008 and August 2008, the clinical data of 177 patients with colorectal cancer were analyzed retrospectively, who were divided into open group (n=122) and laparoscopic group (n=55) by surgery methods. Open group was further divided into FT group (n=66) and traditional group (n=56). Early rehabilitations were studied and compared among three groups. Results ① The baseline characteristics of patients among three groups were no significant differences (Pgt;0.05) exclude operation time. ② In early rehabilitation, the first flatus of patients in both the FT group 〔(3.86±1.01) d〕 and the laparoscopic group 〔(3.78±1.10) d〕 was significantly earlier than that in the traditional group 〔(4.43±1.25) d〕, Plt;0.05. ③ The first oral intaking in the FT group 〔(2.52±1.14) d〕 was earlier than that in the traditional group 〔(3.38±1.43) d〕 and the laparoscopic group 〔(5.04±2.24) d〕, Plt;0.05, while in the traditional group was earlier than that in the laparoscopic group (Plt;0.05). ④ For drainage management, both the FT group and the traditional group were significantly earlier than those in the laparoscopic group (Plt;0.05). ⑤ For postoperative hospital stay, in the FT group 〔(8.33±1.98) d〕 was also much shorter than that in the laparoscopic group 〔(10.55±3.14) d〕 and the traditional group 〔(10.82±3.76) d〕, Plt;0.05. ⑥ For the postoperative complications, there was no significant difference among three groups (Pgt;0.05). Conclusions FT surgery and laparoscopic technique could both enhance recovery of bowel function, and FT could also shorten postoperative hospital stay. However, further studies are needed to develop a better management.
