摘要:

目的 探讨结直肠癌患者血清外泌体微小RNA-23b(miR-23b)、微小RNA-152-3p(miR-152-3p)表达水平,并分析其与病理特征的相关性及其对预后的预测价值。方法 前瞻性选取2020年12月-2024年12月于本院诊治的结直肠癌患者100例,检测其血清外泌体miR-23b、miR-152-3p表达水平,并分析其与病理特征的相关性。依据术后1年内预后情况分为不良组、良好组,比较两组血清外泌体miR-23b、miR-152-3p表达水平,并分析其交互作用对预后不良的影响,并评价其对预后的预测价值。结果 miR-23b、miR-152-3p表达水平与肿瘤分化程度呈正相关,而与TNM分期、淋巴结转移呈负相关(P<0.05);不良组血清外泌体miR-23b、miR-152-3p表达水平低于良好组(P<0.05);miR-23b低水平、miR-152-3p低水平在预后不良风险中呈正向交互作用(P<0.05);术前miR-23b、miR-152-3p表达水平联合预测预后的AUC值明显高于单项指标预测(P<0.05)。结论 结直肠癌患者血清外泌体miR-23b、miR-152-3p表达水平降低在预后不良风险中呈正向交互作用,联合检测其水平对预后的预测价值优于单项指标预测。

Abstract:

Objective To investigate the expression levels of serum exosomal microRNA-23b (miR-23b) and microRNA-152-3p (miR-152-3p) in patients with colorectal cancer, and to analyze their associations with pathological characteristics as well as their prognostic predictive value. Methods A total of 100 patients with colorectal cancer who were diagnosed and treated at our hospital from December 2020 to December 2024 were prospectively enrolled. Serum exosomal miR-23b and miR-152-3p expression levels were measured, and their correlations with pathological characteristics were analyzed. Based on prognosis within 1 year after surgery, patients were divided into a poor-prognosis group and a good-prognosis group. Serum exosomal miR-23b and miR-152-3p expression levels were compared between the two groups, and the interaction effect of the two markers on poor prognosis was analyzed. Their prognostic predictive value was also evaluated. Results The expression levels of miR-23b and miR-152-3p were positively correlated with tumor differentiation, but negatively correlated with TNM stage and lymph node metastasis(P<0.05). Serum exosomal miR-23b and miR-152-3p expression levels were lower in the poor-prognosis group than in the good-prognosis group (P<0.05). Low miR-23b expression and low miR-152-3p expression showed a positive interaction effect on the risk of poor prognosis (P<0.05). The AUC of the combined preoperative miR-23b and miR-152-3p model for predicting prognosis was significantly higher than that of either marker alone (P<0.05). Conclusion Reduced serum exosomal miR-23b and miR-152-3p expression in patients with colorectal cancer exhibits a positive interaction effect on the risk of poor prognosis. Combined detection of these markers has better prognostic predictive value than either marker alone.
