目的 探讨新辅助化学疗法（化疗）对结直肠癌手术患者炎症因子水平的影响。 方法 回顾2008年1月－2009年12月诊断为结直肠癌的487例患者的临床资料，剔除不符合研究条件者后，共390例，以是否接受过新辅助化疗分为术前化疗组（化疗组）156例与对照组234例进行研究。分别比较两组在入院时、术前、术后的炎症因子水平。 结果 入院时两组外周血白细胞、C反应蛋白（CRP）、纤维蛋白原、血清淀粉样蛋白水平差异均无统计学意义（P＞0.05）；术后化疗组CRP水平[（64.09 ± 60.24）mg/L]低于对照组[（87.80 ± 61.54）mg/L]，差异有统计学意义（P＜0.05）；其余炎症因子组间差异无统计学意义（P＞0.05）。 结论 新辅助化疗不会刺激机体产生免疫反应，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.
