【摘要】Objective To investigate the expression and signiifcance of CD19+PD-L1+ tumor inifltrating B lymphocytes in breast tumor tissue.Methods The expressions of CD19+PD-L1+ tumor inifltrating B cells in 31 cases of breast ifbroadenoma, 16 cases of intraductal papilloma, 15 cases of ductal carcinoma in situ and 134 cases of invasive ductal
carcinomas
were
detected
by
using
immunohistochemistry.Result(1)The expression intensity of CD19+PD-L1+ B cells in invasive ductal carcinomas is significantly higher than the breast fibroadenoma, intraductal papilloma and ductal carcinoma in situ (P﹤0.0001). (2)The correlation of HER2 is close to statistical signiifcance (P=0.073).Conclusion CD19+PD-L1+ B cells has a certain correlation with the development of breast malignant tumors. Whether CD19+PD-L1+ B cells is mediated immune escape and other immune effect in breast ductal carcinoma cells deserves further study.%目的:探讨CD19+PD-L1+肿瘤浸润性B淋巴细胞在乳腺肿瘤组织中的作用以及生物学意义,为进一步了解B细胞在肿瘤免疫应答的作用提供理论基础。方法利用免疫组织化学多种染色技术分析CD19+PD-L1+肿瘤浸润B细胞在31例乳腺纤维
