摘要: 目的探讨微小RNA7(miR7)在卵巢癌患者血清中的表达及其临床意义。方法收集广东省佛山市南海区第六人民医院妇科2011年1月至2012年1月经病理组织学确诊的42例卵巢癌患者和40例在该院进行体检的健康女性的血清,采用反转录聚合酶链反应(RTPCR)分别检测两组血清样本miR7的表达,并分析其表达与卵巢癌临床特征的关系。结果与健康对照组相比,卵巢癌患者血清中miR7表达显著下降(0.246±0.017∶0.488±0.042),差异有统计学意义(t=11.23,P=0.01)。miR7的表达与患者临床分期(t=10.12,P=0.01)、组织学类型(t=6.90,P=0.02)、分化程度(t=4.46,P=0.03)、区域淋巴结或远处转移(t=5.62,P=0.02)有关,而与患者的年龄(t=0.03,P=0.83)无关。生存期分析结果显示,miR7高表达的卵巢癌患者总生存期长于低表达组(36.7个月∶24.3个月),差异有统计学意义(χ2=6.04,P=0.02)。结论miR7在卵巢癌患者血清中表达下调,有助于卵巢癌病情评估,可能是卵巢癌患者重要的预后指标之一。

Abstract: ObjectiveTo explore the expression and clinical significance of microRNA7 (miR7) in serum of ovarian cancer patients. MethodsSerum samples of 42 ovarian patients confirmed by pathological histology and 40 healthy women who underwent a physical exam were collected from January 2011 to January 2012 in the Sixth People′s Hospital of Foshan Nanhai District of Guangdong Province. Expression levels of miR7 in the serum samples of the two groups were examined using reverse transcriptionreal time polymerase chain reaction (RTPCR). The relationship between the expression of miR7 and the clinicopathologic feature of ovarian was analyzed. ResultsCompared with the controls, the expression of miR7 in the serum of ovarian cancer patients was significantly reduced (0.246±0.017 vs. 0.488±0.042), with a significant difference (t=11.23, P=0.01). The expression of miR7 in the serum of ovarian cancer patients was related to the clinical stage (t=10.12, P=0.01), pathological type (t=6.90, P=0.02), differentiation degree (t=4.46, P=0.03), regional lymph node or distant metastasis (t=5.62, P=0.02), but it was not related to the age (t=0.03, P=0.83). The patients with high miR7 expression had better overall survival than the patients with low miR7 expression (36.7 months vs. 24.3 months), with a significant difference (χ2=6.04, P=0.02). ConclusionThe expression of miR7 in serum of ovarian cancer patients is down regulated, which may be helpful for the overall assessment of ovarian carcinoma. miR7 may be one of the important prognostic indicators for ovarian carcinoma.
