摘要:
目的 检测子宫内膜癌(endometrial cancer,EC)患者外周血单个核细胞(peripheral blood mononuclear cell,PBMC)miR-30b、miR-96水平,探究其与临床病理及预后的关系。 方法 选择2012年10月—2014年8月温州市中西医结合医院收治的EC患者及门诊健康体检者(对照组)各76例,荧光定量PCR检测PBMC中miR-30b、miR-96水平,Pearson法分析二者相关性,Kaplan-Meier法分析二者与5年生存率的关系;Cox分析不良预后的危险因素。 结果 EC患者PBMC中miR-30b、miR-96水平均高于对照组(t=21.913、24.188,均P<0.05),二者呈正相关(r=0.553,P<0.05),均与病理分级、FIGO分期、肌层浸润及淋巴结转移有关(均P<0.05)。miR-30b高表达者5年总生存率(16.13%)低于低表达者(66.67%,χ2=16.890,P<0.05);miR-96高表达者5年总生存率(18.18%)低于低表达者(67.44%,χ2=16.307,P<0.05)。miR-30b、miR-96、FIGO分期、淋巴结转移是预后的影响因素(HR=2.861, 95% CI: 1.427~5.736;HR=1.973, 95% CI: 1.462~2.663;HR=2.235, 95% CI: 1.491~3.350;HR=2.439, 95% CI: 1.365~4.358;均P<0.05)。 结论 PMBC中miR-30b、miR-96高表达,与EC患者病理分级、FIGO分期、肌层浸润、淋巴结转移及5年生存率有关,是影响预后的独立危险因素。 Abstract:Objective The levels of miR-30b and miR-96 in peripheral blood mononuclear cells (PBMC) in patients with endometrial carcinoma (EC) were detected to explore their relationship with clinicopathology and prognosis. Methods A total of 76 EC patients and healthy outpatients(control group)admitted to Wenzhou hospital of integrated traditional Chinese and western medicine were selected. The expression levels of miR-30b and miR-96 in PBMC were detected by fluorescence quantitative PCR, the correlation was analyzed by Pearson method, the relationships between miR-30b and miR-96 expression levels in PBMC and 5-year survival rate of EC patients were analyzed by Kaplan-Meier method, and the risk factors affecting the prognosis of EC patients were analyzed by Cox regression. Results The expression levels of miR-30b and miR-96 in PBMC of EC patients were higher than those of control group (t=21.913, 24.188, all P < 0.05). They were positively correlated (r=0.553, P < 0.05), and correlated with pathological grade, FIGO stage, depth of muscle invasion and lymph node metastasis (P < 0.05). The 5-year overall survival rate of patients with high expression of miR-30b (16.13%) was lower than that of patients with low expression (66.67%, χ2=16.890, P < 0.05). The 5-year overall survival rate of patients with high expression of miR-96 (18.18%) was lower than that of patients with low expression (67.44%, χ2=16.307, P < 0.05). Levels of miR-30b and miR-96, FIGO stage and lymph node metastasis in PMBC were independent risk factors affecting the prognosis of EC patients (HR=2.861, 95% CI: 1.427-5.736; HR=1.973, 95% CI: 1.462-2.663; HR=2.235, 95% CI: 1.491-3.350; HR=2.439, 95% CI: 1.365-4.358; all P < 0.05). Conclusion The miR-30b and miR-96 are highly expressed in PMBC, which are related to pathological grade, FIGO stage, muscle invasion, lymph node metastasis and 5-year survival rate of EC patients, and are independent risk factors for adverse prognosis of EC patients. -
