［摘 要］ 目的：研究肿瘤相关性成纤维细胞（cancer⁃associated fibroblast，CAF）与CD4 、CD8 T淋巴细胞在乳腺癌发生发展及
+
+
淋巴结转移中的相关性。方法：检测乳腺浸润性导管癌组织及癌旁组织中CAF相关蛋白α⁃平滑肌肌动蛋白（α⁃SMA）的表达和
间质淋巴细胞CD4、CD8的表达，并结合临床病理特征进行统计学分析，从而探寻CAF诱导的免疫抑制与乳腺癌发生发展及淋
巴结转移程度之间的相关性。结果：α⁃SMA蛋白在乳腺癌组织中呈高表达，并与肿瘤大小、临床分期及淋巴结转移呈正相关
（P＜0.05）；CD4 的阳性表达与年龄、肿瘤大小及临床分期无相关性（P＞0.05），而与组织学分级及淋巴结转移呈负相关（P＜
0.05）。CD8 的阳性表达与年龄、肿瘤大小及临床分期无相关性（P＞0.05），而与组织学分级及淋巴结转移呈正相关（P＜
0.05）。经配对计数资料的相关分析，α⁃SMA蛋白的阳性表达与CD8阳性表达存在正相关（P＜0.01），与CD4阳性表达存在负
相关（P＜0.01）。结论：CAF及上述免疫细胞的异常促进了乳腺癌发生发展及淋巴结转移，可为评估乳腺癌患者的生存及预后
提供可靠的实验室依据。

［Abstract］ Objective： To study correlation of cancer⁃associated fibroblasts（CAFs），CD4 ，CD8 T lymphocyte with developments
and lymph node metastasis of breast carcinoma. Methods：Immunohistochemistry method（S⁃P）was used to examine the expression of α⁃
smooth muscle actin（α⁃SMA），CD4 and CD8 in breast invasive ductal carcinoma，and the relationships with the clinicopathological
features of breast carcinoma were analyzed to explore the correlation between CAFs induced immunosuppression and the development
and lymph node metastasis of breast carcinoma. Results：The positive rate of α⁃SMA was significantly higher in breast carcinoma than
that in control. The expression rate of α⁃SMA was positively correlated to the tumor size，TNM stage and lymph nodal involvement（P＜
0.05）. The expression of CD4 was negatively correlated to the grade and lymph nodal involvement（P＜0.05）. The expression of CD8
was positively correlated to the grade and lymph nodal involvement（P＜0.05）. The expression of α⁃SMA was positively correlated to
the expression of CD8（P＜0.01），and it was negatively correlated to the expression of CD4（P＜0.01）. Conclusion：Abnormal CAFs
+ +
and CD4 ，CD8 T lymphocytes promote the occurrence，development and lymphatic metastasis of breast cancer，and they provide
reliable laboratory basis to evaluate the survival and prognosis of breast cancer patients.
