摘要:

目的 探讨miR-206、miR-125、miR-21在乳腺癌新辅助化疗疗效和预后评估中的价值。方法 选取2021年7月—2022年7月河北北方学院附属第一医院行新辅助化疗的乳腺癌患者82例(乳腺癌组),以40名健康体检者作为正常对照组。收集所有对象的临床资料,并检测乳腺癌患者化疗前和正常对照者的血清miR-206、miR-125、miR-21水平。根据新辅助化疗的疗效分为化疗无效组和化疗有效组。化疗结束后随访1年,根据乳腺癌患者的生存情况分为生存组和死亡组。采用Logistic回归分析评估乳腺癌患者新辅助化疗疗效的影响因素。采用受试者工作特征(ROC)曲线评估各项指标判断新辅助化疗疗效的效能。采用Kaplan-Meier生存曲线评估乳腺癌患者的生存情况。采用Cox回归分析评估影响乳腺癌患者生存率的危险因素。结果 乳腺癌组血清miR-206、miR-125相对表达量低于正常对照组(P<0.001),血清miR-21水平高于正常对照组(P<0.001)。化疗无效组与化疗有效组之间肿瘤直径、临床分期、病理分级和血清miR-206、miR-125、miR-21相对表达量差异均有统计学意义(P<0.05)。ROC曲线分析结果显示,miR-206、miR-125、miR-21单项和联合检测判断化疗无效的曲线下面积(AUC)分别为0.795、0.761、0.782、0.899。多因素Logistic回归分析结果显示,校正肿瘤直径、临床分期、病理分级后,血清miR-206、miR-125低表达和miR-21高表达是乳腺癌患者化疗无效的独立危险因素(P<0.05)。生存组与死亡组临床分期、病理分级和血清miR-206、miR-125、miR-21相对表达量差异均有统计学意义(P<0.05)。ROC曲线分析结果显示,血清miR-206、miR-125、miR-21单项检测和联合检测判断乳腺癌患者1年死亡的AUC分别为0.757、0.698、0.676、0.838。Kaplan-Meier生存曲线分析结果显示,miR-206高表达组、miR-125高表达组1年生存率分别高于血清miR-206低表达组和miR-125低表达组(P<0.05),miR-21低表达组1年生存率高于miR-21高表达组(P<0.05)。Cox回归分析结果显示,校正临床分期、病理分级后,血清miR-206、miR-125低表达和miR-21高表达均是乳腺癌患者1年死亡的独立危险因素(P<0.05)。结论 乳腺癌患者血清miR-206、miR-125、miR-21异常表达,或可作为患者接受新辅助化疗疗效和预后评估的指标。

Abstract:

Objective To investigate the roles of miR-206,miR-125 and miR-21 in efficacy and prognosis evaluation of neo-adjuvant chemotherapy for breast cancer. Methods From July 2021 to July 2022,82 breast cancer patients(breast cancer group) who received neo-adjuvant chemotherapy in the First Affiliated Hospital of Hebei North University were enrolled,and 40 healthy subjects were enrolled as healthy control group. The clinical data of all the research subjects were collected,and serum levels of miR-206,miR-125 and miR-21 in breast cancer group before chemotherapy and healthy control group were determined. According to the efficacy of neo-adjuvant chemotherapy,the research subjects were classified into chemotherapy ineffective group and chemotherapy effective group. The patients were followed up for 1 year after chemotherapy,and they were classified into survival group and death group according to the survival of breast cancer patients. Logistic regression analysis was used to evaluate the influencing factors of neo-adjuvant chemotherapy in breast cancer patients. The efficacy of various indicators for evaluating neo-adjuvant chemotherapy was evaluated by receiver operating characteristic(ROC) curve. Kaplan-Meier survival curve was used to evaluate the survival of breast cancer patients. Cox regression analysis was used to evaluate the risk factors affecting the survival rate of breast cancer patients. Results The relative expression levels of miR-206 and miR-125 in serum of breast cancer group were lower than those of healthy control group(P<0.001),and the relative expression level of miR-21 in serum was higher than that of healthy control group(P<0.001). There was statistical significance in tumor diameter,clinical stage,pathological grade and relative expression levels of miR-206,miR-125 and miR-21 in serum between chemotherapy ineffective group and chemotherapy effective group(P<0.05). The area under curve(AUC) for single and combined determinations of miR-206,miR-125 and miR-21 to evaluate chemotherapy efficacy were 0.795,0.761,0.782 and 0.899,respectively. Multivariate Logistic regression analysis showed that after adjusting tumor diameter,clinical stage and pathological grade,the low expression of miR-206,miR-125 and high expression of miR-21 in serum were independent risk factors for chemotherapy ineffectiveness in breast cancer patients(P<0.05). There was statistical significance in clinical stage,pathological grade and relative expression levels of serum miR-206,miR-125 and miR-21 between survival group and death group(P<0.05). The AUC of serum miR-206,miR-125,miR-21 single and combined determinations to judge the 1-year death of breast cancer patients were 0.757,0.698,0.676,0.838,respectively. Kaplan-Meier survival curve analysis results showed that the 1-year survival rates of miR-206 high expression group and miR-125 high expression group were higher than those of serum miR-206 low expression group and miR-125 low expression group,respectively(P<0.05). The 1-year survival rates of miR-21 low expression group were higher than those of miR-21 high expression group(P<0.05). Cox regression analysis showed that after adjusting clinical stage and pathological grade,the low expression of miR-206,miR-125 and high expression of miR-21 in serum were independent risk factors for 1-year death of breast cancer patients(P<0.05). Conclusions The abnormal expressions of miR-206,miR-125 and miR-21 in serum of patients with breast cancer may be used as the indicators for evaluating efficacy and prognosis of patients receiving neo-adjuvant chemotherapy.
