There has been no consensus regarding treatments. We will report a case of Adenoid cystic carcinoma of the breast presented with localized disease and no axillary lymph node metastases. We performed a radical mastectomy with axillary lymph node dissection, with a favorable clinical course and we will describe the clinic pathologic features of ACC of the breast and review the current literature.展开更多
目的:探讨PD-1及PD-L1在三阴性乳腺癌(triple negative breast carcinoma,TNBC)中的表达情况。方法:收集158例TNBC组织标本,应用免疫组化方法进行PD-1及PD-L1的染色,观察其在TNBC中的表达情况,分析PD-1及PD-L1的表达与各项临床病理因素...目的:探讨PD-1及PD-L1在三阴性乳腺癌(triple negative breast carcinoma,TNBC)中的表达情况。方法:收集158例TNBC组织标本,应用免疫组化方法进行PD-1及PD-L1的染色,观察其在TNBC中的表达情况,分析PD-1及PD-L1的表达与各项临床病理因素的关系。结果:PD-L1在TNBC肿瘤细胞及间质淋巴细胞中的表达率分别为53.2%和74.7%,PD-1在间质淋巴细胞中的表达率为64.6%;PD-L1与PD-1的表达有相关性(P<0.05);PD-L1及PD-1的表达与TNBC的肿瘤体积大、高组织学级别、基底样型BC(basal like breast carcinoma,BLBC)、Ki67增殖指数高及肿瘤浸润淋巴细胞(tumor infiltrating lymphocyte,TIL)高百分比相关(P<0.05),多因素回归分析提示肿瘤的大小、BLBC、Ki67高增殖指数及TIL高百分比是PD-L1和PD-1表达的危险因素;PD-L1及PD-1在伴髓样特征的癌、伴大汗腺特征的癌及化生性癌中高表达,在浸润性小叶癌、腺样囊性癌及腺泡细胞癌中不表达。结论:PD-L1及PD-1在TNBC中高表达,可以作为TNBC免疫治疗的靶标及预后标记物;肿瘤体积大、BLBC、Ki67增殖指数高及高TIL是PD-L1及PD-1表达的危险因素;PD-L1及PD-1表达在TNBC中存在组织学异质性。展开更多
