目的

探讨进展期直肠癌患者新辅助治疗(NAT)疗效,寻找可以有效预测NAT后病理完全缓解的临床和病理因素。

方法

回顾性分析2018年6月~2020年12月期间在山西省肿瘤医院行NAT并行全直肠系膜切除术的进展期直肠癌患者129例,根据其NAT后的反应(术后病理结果),分为病理完全缓解(pCR)和非病理完全缓解(non-pCR)两组,对性别、年龄、肿瘤距肛缘距离、术前T分期、N分期、治疗前CEA水平、肿瘤最大直径、微卫星状态、术前联合放疗等几项指标进行统计学分析。

结果

共纳入129例患者,其中NAT后pCR患者15例(11.6%)。单因素分析显示,术前CEA水平低的患者NAT后pCR的比例(21.3%)明显高于CEA水平高者(2.9%),术前联合放化疗的患者pCR比例(23.1%)明显高于术前单纯化疗的患者(6.7%)(χ2=5.623,P<0.05);微卫星状态稳定的患者pCR比例(12.3%)在数值上高于微卫星状态不稳定的患者(6.7%),差异无统计学意义(P>0.05)。Logistic回归分析显示,治疗前CEA水平高(OR=12.570,95%CI:2.515~62.830)和术前联合放化疗(OR=6.319,95%CI:1.850~21.580),是NAT后达到pCR的独立因素。通过ROC曲线发现Logistic回归模型预测pCR率最佳截断值为0.87,灵敏度为0.82,特异度为0.87,AUC值为0.885。术前CEA<2.315 μg/L是预测NAT达到pCR的有效指标。

结论

治疗前CEA水平和术前联合放化疗可以作为临床评估NAT疗效的参考指标。

Objective

To explore the efficacy of neoadjuvant therapy in patients with advanced rectal cancer, and to find pathological and clinical factors that can predict pathological complete response of neoadjuvant therapy.

Methods

A retrospective analysis was conducted in 129 patients with rectal cancer who underwent neoadjuvant therapy and total mesorectal resection at Shanxi Cancer Hospital from June 2018 to December 2020. According to their response to neoadjuvant therapy (postoperative pathological results), they were divided into two groups of pathological complete response (pCR) and non- pathological complete response(non-pCR). Statistical analysis was performed on several indicators of gender, age, distance from the tumor to the anal verge, preoperative T stage, N stage, CEA level before treatment, maximum tumor diameter, microsatellite status, and preoperative combined radiotherapy.

Results

A total of 129 patients were included, including 15 patients (11.6%) with pCR after neoadjuvant therapy. Univariate analysis showed that the proportion of patients with low preoperative CEA level in pCR after neoadjuvant therapy (21.3%) was significantly higher than that in patients with high CEA level (2.9%), and the proportion of patients with preoperative combined chemoradiotherapy (23.1%) was significantly higher in pCR than that in patients with preoperative chemotherapy alone (6.7%) (χ2=5.623, P<0.05); the proportion of pCR in patients with microsatellite stability (12.3%) was numerically higher than that in patients with microsatellite instability (6.7%) (P>0.05). Logistic regression analysis showed that high CEA level before treatment (OR=12.570, 95%CI: 2.515~62.830) and preoperative combined chemoradiotherapy (OR=6.319, 95%CI: 1.850~21.580) were associated with pCR after neoadjuvant therapy independent factor. The ROC curve, it was found that the best cut-off value of the logistic regression model to predict the pCR rate was 0.87, the sensitivity was 0.82, the specificity was 0.87, and the AUC value was 0.885. Preoperative CEA <2.315 μg/L was an effective indicator to predict pCR with neoadjuvant therapy.

Conclusion

CEA level before treatment and preoperative combined chemoradiotherapy can be used as reference indicators for clinical evaluation of the efficacy of neoadjuvant therapy. Microsatellite status was not found to be an independent prognostic factor for pCR after neoadjuvant therapy for rectal cancer.
