乳腺黏液癌(MC)是浸润性导管癌的一种少见亚型,多发生于老年女性,占所有乳腺浸润性癌的2%~3.6%。与浸润性导管癌相比,MC的肿瘤体积更小、核级更低、淋巴结转移更少见,因此其5年生存率高达94%,20年生存率也可达81%,但目前对其前期病变尚无系统性研究。作者收集了130例MC,确定其中的原位癌(DCIS)成分,研究黏液型DCIS与MC的转化关系及其免疫表型。作者将MC分为单纯性MC(106例)和混合性MC(24例),前者又分为A型和B型,A型(71例)指超过60%的肿瘤成分为细胞外黏液,B
Mucinous mucinous carcinoma (MC) is a rare subtype of invasive ductal carcinoma that occurs in older women, accounting for 2% to 3.6% of all breast invasive carcinomas. Compared with invasive ductal carcinoma, MC has a 5-year survival rate of 94% and a 20-year survival rate of up to 81%, with smaller tumor size, lower nuclear grade, and less lymph node metastasis. However, at present, There is no systematic study of the disease. The authors collected 130 cases of MC, to determine which of the DCIS components, mucinous DCIS and MC conversion and immunophenotype. The authors divided MC into simple MC (n = 106) and mixed MC (n = 24). The former was divided into type A and type B. The type A (71 cases) means more than 60% of the tumor components were extracellular mucus, B
