摘要: 目的 探讨肿瘤相关巨噬细胞(Tumor-associated macrophages,TAMs)在三阴性乳腺癌(Triple-negative breast cancer,TNBC)中的表达及其与临床病理因素和预后的关系。方法 应用免疫组化染色法检测108例TNBC组织中TAMs的表达情况,同时检测癌组织中微血管密度(Microvessel density,MVD),分析TAMs表达与TNBC临床病理参数、MVD及预后的关系。结果 TAMs表达与患者年龄无关,与肿瘤大小、淋巴结转移、组织学分级、TNM分期及MVD密切相关。生存分析显示TAMs与TNBC术后5年无病生存时间(Disease-free survival,DFS)及总生存时间(Overall survival,OS)相关;MVD与5年DFS相关,而与OS未见相关性。Cox回归分析示TAMs是TNBC预后不良的独立危险因素。结论 TAMs高表达提示TNBC预后不良,TAMs可成为判断预后的免疫指标之一。TAMs与MVD密切相关,可能通过促进瘤内血管增生,从而促进TNBC的生长、侵袭和转移,进一步影响TNBC患者的预后。

Abstract: Objective To explore the significances of expression of tumor associated macrophages(TAMs)and its correlation with microvessel density(MVD)in triple negative breast cancer(TNBC).Methods Immunohistochemistry was used to detect TAMs and MVD expression in 108 TNBC tissues and to analyze the correlation between TAMs with clinicopathological features,prognosis and MVD.Results The expression of TAMs was correlated with the tumor size,lymph node metastasis,histological grade,TNM stage and MVD,but had no statistically significant association with age.TAMs was correlated with 5 year disease free survival(DFS)and overall survival(OS);MVD was correlated with 5 year DFS,while no correlation with OS.Univariate and multivariate analyses showed that TAMs was an independent unfavorable prognostic factor for patients with TNBC.Conclusion High infiltration of TAMs indicated poor survival rate for patients with TNBC.The infiltration of TAMs was a new,important risk factor for TNBC recurrence.TAMs were closely related to MVD,by promoting tumor angiogenesis,thereby promoting TNBC growth,invasion and metastasis,and further affect the prognosis of patients with TNBC.
