摘要:

目的 探讨程序化细胞死亡分子5(PDCD5)蛋白在乳腺癌中的表达及其与腋窝淋巴结转移的关系。方法 收集160例乳腺癌患者的癌组织及对应的癌旁组织样本,采用免疫组化法检测PDCD5、周期蛋白(Cyclin)D1、Ki-67、趋势化因子受体4(CXCR4)、E-钙黏蛋白(E-cad)的表达。收集所有患者的临床病理特征资料,并随访5年,统计无进展生存期(PFS)和总生存期(OS)。采用Spearman相关分析评估各项目之间的相关性。采用Kaplan-Meier生存曲线分析乳腺癌患者的生存率。采用Cox比例回归分析评估乳腺癌患者预后的影响因素。结果 乳腺癌组织中PDCD5蛋白的阳性表达率为25.0%(40/160),明显低于癌旁组织[60.0%(96/160)](P=0.000)。PDCD5蛋白表达与不同TNM分期、组织分化程度、是否有淋巴结转移、是否有肌层浸润、是否有脉管浸润及不同雌激素受体(ER)、孕激素受体(PR)、人类表皮生长因子受体(HER-2)表达状态有关(P<0.05),与年龄、月经状态、肿瘤直径及分子分型无关(P>0.05)。Spearman相关分析结果显示,PDCD5蛋白表达与腋窝淋巴结转移数目呈正相关(r=0.428,P=0.000);与Cyclin D1、 Ki-67和CXCR4表达呈负相关(r值分别为-0.217、-0.220、-0.271,P<0.05),与E-cad表达呈正相关(r=0.464,P=0.000)。Cox比例回归分析结果显示,TNM分期Ⅲ~Ⅳ期、低组织分化程度、肌层浸润、脉管浸润、PDCD5阳性、ER阴性、PR阴性、HER-2阳性是乳腺癌腋窝淋巴结转移的危险因素(P<0.05)。结论 PDCD5在乳腺癌组织中呈低表达,可能通过调控运动相关蛋白CyclinD1、Ki-67、CXCR4及E-cad促进乳腺癌腋窝淋巴结转移的发生。

Abstract:

Objective To investigate the relationship between the expression of programmed cell death 5(PDCD5) protein and axillary lymph node metastasis in breast cancer. Methods The expressions of PDCD5,cyclin(Cyclin) D1,Ki-67,chemokine receptor 4(CXCR4) and E-cadherin(E-cad) were determined by immunohistochemical method. The clinicopathologic characteristics of all the patients were collected,and they were followed up for 5 years. The progression-free survival(PFS)and overall survival(OS) were calculated. Spearman correlation analysis was used to evaluate the correlation between projects. Kaplan-Meier survival curve was used to analyze the survival rate of patients with breast cancer. Cox regression proportional hazard model was used to analyze the prognostic factors of patients with breast cancer. Results The positive expression rate of PDCD5 protein in breast cancer tissues was 25.0%(40/160),which was lower than that in adjacent normal tissues [60.0%(96/160)] (P=0.000). The expression of PDCD5 protein had statistical significance among different TNM stages,histological differentiation,lymph node metastasis,myometrial invasion,vascular invasion and different expression states of estrogen receptor(ER),progesterone receptor(PR) and human epidermal growth factor receptor 2(HER-2)(P<0.05). There was no relation among different ages,menstrual states,tumor diameters and molecular types of breast cancer(P>0.05). The results of Spearman correlation analysis showed that the expression of PDCD5 protein was positively correlated with the number of axillary lymph node metastasis(r=0.428,P=0.000),it was negatively correlated with the expression of Cyclin D1,Ki-67 and CXCR4(r=-0.217,-0.220 and -0.271,respectively,P<0.05),and it was positively correlated with the expression of E-cad(r=0.464,P=0.000). The results of Cox regression proportional hazard model showed that TNM stage Ⅲ-Ⅳ,low tissue differentiation,myometrial invasion,vascular invasion,PDCD5 positive,ER negative,PR negative and HER-2 positive were the risk factors of axillary lymph node metastasis in breast cancer. Conclusions The low expression of PDCD5 in breast cancer may promote the occurrence of axillary lymph node metastasis by regulating exercise-related protein Cyclin D1,Ki-67,CXCR4 and E-cad.
