目的

对比自膨式金属支架(SEMS)植入后序贯新辅助治疗与腹腔镜手术在梗阻性结直肠癌(OCRC)中的应用效果。

方法

采用回顾性队列研究与倾向评分匹配(PSM),收集2018年2月至2024年10月于空军军医大学唐都医院接受SEMS植入的157例梗阻性结直肠癌患者的临床资料,根据后续治疗策略分为桥接腹腔镜手术组(桥接组)和序贯新辅助治疗与腹腔镜手术组(序贯组)。经1∶2倾向评分匹配后,共纳入60例患者,其中桥接组20例,序贯组40例,比较两组围手术期指标、肿瘤病理特征及生存结局。

结果

序贯组SEMS-手术间隔时间显著延长(t=8.22,P<0.05),但术后住院时间明显缩短(t=3.15,P<0.05)。安全性与可行性方面,序贯组属于中等手术风险(ASA Ⅲ级)的患者比例略低于桥接组(7.5% vs. 20.0%,Z=−1.81,P>0.05),且Ⅰ期造口率更低(7.5% vs. 20.0%,χ2=0.99,P>0.05),而手术时长、R0切除率、术中输血例数、手术标本质量(CME或TSME)、术后首次肛门排气时间及术后并发症总发生率等方面与桥接组相当。肿瘤学结局方面,两组患者术后病理TNM分期差异有统计学意义(Z=−2.10,P<0.05),且序贯组病理完全缓解率为12.5%,而序贯组肿瘤长径略小于桥接组(Z=−1.17,P>0.05)。序贯组清扫淋巴结数目多于桥接组,而阳性淋巴结数目少于桥接组,以及阳性淋巴结比例低于桥接组,但差异均无统计学意义(均P>0.05)。序贯组无病生存率显著优于桥接组(χ2=4.13,P<0.05),总生存率差异虽无统计学意义(χ2=1.31,P>0.05),但显现出更优趋势。

结论

OCRC患者SEMS植入后序贯新辅助治疗与腹腔镜手术安全可行,利于患者术后恢复,改善无病生存。

Objective

To compare the efficacy of sequential neoadjuvant therapy following self-expanding metal stent (SEMS) placement versus laparoscopic surgery alone in obstructive colorectal cancer (OCRC).

Methods

A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 157 patients with OCRC who underwent SEMS placement at Tangdu Hospital, Air Force Medical University from February 2018 to October 2024 were collected. Patients were divided into a bridging laparoscopic surgery group (bridging group) and a sequential neoadjuvant therapy plus laparoscopic surgery group (sequential group) according to subsequent treatment strategies. After 1:2 PSM, a total of 60 patients were included, with 20 in the bridging group and 40 in the sequential group. Perioperative outcomes, tumor pathological characteristics, and survival outcomes were compared between the two groups.

Results

The interval from stent placement to surgery was significantly longer in the sequential group (t=8.22, P<0.05), but the postoperative hospital stay was significantly shorter (t=3.15, P<0.05). Regarding safety and feasibility, the proportion of patients with moderate surgical risk (ASA class III) was slightly lower in the sequential group (7.5% vs. 20.0%, Z=−1.81, P>0.05), and the rate of primary stoma creation was also lower (7.5% vs. 20.0%, χ2=0.99, P>0.05). The two groups were comparable in terms of operative time, R0 resection rate, intraoperative blood transfusion rate, quality of surgical specimens (CME or TSME), time to first postoperative flatus, and overall incidence of postoperative complications. In terms of oncological outcomes, there was a statistically significant difference in postoperative pathological TNM staging between the two groups (Z=−2.10, P<0.05), with a pathological complete response rate of 12.5% in the sequential group. The tumor diameter was slightly smaller in the sequential group (Z=−1.17, P>0.05). The sequential group had a higher number of harvested lymph nodes and fewer positive lymph nodes, as well as a lower positive lymph node ratio compared to the bridging group, although these differences were not statistically significant (all P>0.05). The disease-free survival rate was significantly better in the sequential group (χ2=4.13, P<0.05). Although the difference in overall survival rate was not statistically significant (χ2=1.31, P>0.05), a superior trend was observed in the sequential group.

Conclusion

Sequential neoadjuvant therapy following SEMS placement and laparoscopic surgery is safe and feasible for OCRC patients, facilitating postoperative recovery and improving disease-free survival.
