【摘要】 目的:回顧性分析SOCS1(細(xì)胞因子信號抑制因子1)在三陰性乳腺癌組織中的表達(dá)及其與臨床病理特征和預(yù)后的關(guān)系。方法:收集本院2011年6月-2013年6月156例三陰性乳腺癌患者根治標(biāo)本,以及其臨床、病理資料,進(jìn)行SOCS1免疫組織化學(xué)檢測,分析SOCS1在三陰性乳腺癌組織中的表達(dá),以及該蛋白與患者臨床病理特征和預(yù)后的關(guān)系。結(jié)果:SOCS1在TNBC癌組織中的陽性表達(dá)為30.77%,顯著低于在癌旁組織中的陽性表達(dá)71.79%(P<0.05);不同年齡、腫瘤大小、組織學(xué)分級、是否絕經(jīng)TNBC患者SOCS1表達(dá)水平差異無統(tǒng)計(jì)學(xué)意義(P>0.05);TNM分期Ⅲ/Ⅳ期、腋窩淋巴結(jié)轉(zhuǎn)移、P53表達(dá)陽性、Ki-67表達(dá)>30%的TNBC患者SOCS1陽性表達(dá)分別低于TNM分期Ⅰ/Ⅱ期、無腋窩淋巴結(jié)轉(zhuǎn)移、P53表達(dá)陰性、Ki-67表達(dá)≤30%的TNBC患者(P<0.05);Cox回歸分析結(jié)果顯示Ki-67表達(dá)>30%、P53陽性表達(dá)、SOCS1陰性表達(dá)是TNBC患者獨(dú)立預(yù)后危險(xiǎn)因素(P<0.05)。結(jié)論:SOCS1在TNBC組織中陽性表達(dá)下降,其與TNBC患者的TNM分期、腋窩淋巴結(jié)轉(zhuǎn)移、P53表達(dá)、Ki-67表達(dá)等臨床病理特征具有明顯相關(guān)性,在TNBC患者疾病的進(jìn)展和預(yù)后中其重要作用。

[Abstract] Objective: To analyze the expression of SOCS1 (cytokine signal inhibitor 1) in triple-negative breast cancer tissues and its relationship with clinicopathological features and prognosis. Method: From June 2011 to June 2013, the clinical and pathological data of 156 patients with triple-negative breast cancer were collected. The expression of SOCS1 in triple-negative breast cancer tissues was analyzed, as well as the relationship between SOCS1 protein and clinicopathological features and prognosis. Result: The positive expression of SOCS1 in TNBC was 30.77%, which was significantly lower than 71.79% of SOCS1 in adjacent normal tissues (P<0.05). There was no significant difference in the expression level of patients with different age, tumor size, histological grade TNBC menopause (P>0.05); TNM stage Ⅲ/Ⅳ, axillary lymph node metastasis, P53 expression positive, Ki-67 expression >30% of TNBC patients with positive expression were lower than those of stage Ⅰ/Ⅱ, no axillary lymph node metastasis, negative P53 expression, 30% Ki-67 expression (P<0.05); Cox regression analysis showed that Ki-67 expression >30%, P53 positive expression and SOCS1 Negative expression is an independent prognostic risk factor in TNBC patients (P<0.05). Conclusion: The positive expression of SOCS1 in TNBC is decreased, which is significantly correlated in clinical and pathological features of TNM stage, axillary lymph node metastasis, P53 expression and Ki67 expression. It plays an important role in the progression and prognosis of TNBC patients.

三陰性乳腺癌(TNBC)是一種免疫組織化學(xué)表現(xiàn)為雌激素受體、孕激素受體、人類表皮生長因子均為陰性的乳腺癌[1]。由于TNBC缺少有效的治療靶點(diǎn),因此該病治療敏感性差,易產(chǎn)生耐藥性,侵襲性強(qiáng),容易復(fù)發(fā)、遠(yuǎn)處轉(zhuǎn)移,比其他類型乳腺癌治療效果、預(yù)后更差[2]。近年來有研究發(fā)現(xiàn),細(xì)胞因子信號抑制因子(SOCS1)在乳腺癌、宮頸癌、胃癌等多種惡性腫瘤中都存在低表達(dá)的現(xiàn)象,該因子的失活是癌癥發(fā)生、發(fā)展的靶標(biāo)之一[3]。還有研究指出恢復(fù)SOCS1的表達(dá)可以抑制肝細(xì)胞肝癌(HCC)細(xì)胞及白血病細(xì)胞的增長,證實(shí)SOCS1具有抑癌特性[4]。因此本次研究主要對SOCS1在TNBC癌組織中的表達(dá)及其與臨床病理特征和預(yù)后的關(guān)系進(jìn)行了探討,為TNBC的治療和預(yù)后改善提供敏感指標(biāo),結(jié)果如下。
