目的
2
探讨术前新辅助放化疗联合程序性死亡受体1(programmed cell death-1,PD-1)抑制剂治疗溃疡性结肠炎相关性结直肠癌(ulcerative colitis related colorectal cancer,UCRCC)的近期效果。
方法
2
回顾性收集2021年3月至2023年12月于南京市第二医院接受PD-1抑制剂联合新辅助放化疗并进行手术的UCRCC病人的临床资料。根据术前治疗方案分为对照组(
n
=46)和联合组(
n
=34)。对照组术前病人仅接受卡培他滨+奥沙利铂方案化疗2个周期,休息2周后再进行2周期的放疗;联合组病人在对照组基础上术前给予PD-1抑制剂,每3周1次,共2周期。两组病人新辅助放化疗结束后4~6周行手术治疗,结直肠全切+回肠造瘘或肠道肿瘤根治术。比较两组病人新辅助治疗效果、肿瘤标志物水平、药物不良
反应情况、围手术期相关指标水平以及术后病理情况。
结果
2
联合组疾病控制率显著高于对照组(
P
<0.05)。联合组糖类抗原242、糖类抗原72-4、癌胚抗原、糖类抗原19-9水平显著低于对照组(
P
<0.05),肿瘤退缩分级0级和1级的比例显著高于对照组。两组病人不良反应发生率和围手术期相关指标比较无显著差异(
P
>0.05)。
结论
2
术前新辅助放化疗联合PD-1抑制剂对UCRCC的控制效果良好,可降低病人肿瘤标志物水平,改善病人术后病理情况,具有一定安全性。
Objective
2
To investigate the short-term effect of preoperative neoadjuvant chemoradiotherapy combined with programmed cell death 1 (PD-1) inhibitors on the treatment of ulcerative colitis related colorectal cancer (UCRCC).
Methods
2
Clinical data of UCRCC patients who received PD-1 inhibitors combined with neoadjuvant therapy and surgically operated in the Second Hospital of Nanjing from March 2021 to December 2023 were retrospectively collected. Patients were divided into the control group (
n
=46) and combination group (
n
=34) based on preoperative treatment regimens. Patients in the control group received two cycles of capecitabine + oxaliplatin chemotherapy preoperatively, followed by two cycles of radiotherapy after a 2-week rest. Those in the combination group received PD-1 inhibitors every 3 weeks for two cycles, plus clinical management as the same as in the control group. All patients underwent surgery (total colorectal resection with ileostomy or radical intestinal tumor resection) 4-6 weeks after neoadjuvant chemoradiotherapy. The effect of neoadjuvant therapy, tumor markers, drug toxicity, side effects, perioperative indicators and postoperative pathology were compared between the two groups.
Results
2
Disease control rate in the combination group was significantly higher than that of the control group (
P
<0.05). The levels of carbohydrate antigen 242, carbohydrate antigen 72-4, carcinoembryonic antigen and carbohydrate antigen 199 in the combination group were sign
ificantly lower than those of the control group (
P
<0.05), and the percentage of tumor regression grades 0 and 1 was significantly higher compared to the control group. There were no significant differences in the incidence of toxic and side effects and perioperative indexes between the two groups (
P
>
0.05).
Conclusion
2
Preoperative neoadjuvant chemoradiotherapy combined with PD-1 inhibitors demonstrates favorable efficacy in controlling UCRCC, reducing tumor marker levels, improving postoperative pathological outcomes, and exhibiting an acceptable safety profile.
