目的探讨乳腺微小癌的临床及病理特点。方法回顾分析46例乳腺微小癌的临床及病理资料。结果46例微小癌中小叶原位癌13例(28.26%),浸润性小叶癌7例(15.21%),导管内癌15例(32.60%),浸润性导管癌11例(23.91%),浸润性导管癌中有4例伴有腋窝淋巴结转移,转移率为20.37%(11/54)。结论乳腺微小癌有多中心性,且在原发病灶尚未充分暴露之前,就有可能发生淋巴结转移,应提高对本病生物学特性的认识。
Objective To investigate the clinical and pathological features of breast cancer. Methods Retrospective analysis of 46 cases of breast cancer clinical and pathological data. Results Of the 46 patients with MCL, 13 (28.26%) had lobular carcinoma in situ, 7 (15.21%) had invasive lobular carcinoma, 15 (32.60%) had intraductal carcinoma and 11 (23.91%) had invasive ductal carcinoma There were 4 cases of ductal carcinoma with axillary lymph node metastasis, the metastasis rate was 20.37% (11/54). Conclusion The breast cancer is multicentric, and lymph node metastasis may occur before the primary lesion has not been fully exposed, and the understanding of the biological characteristics of this disease should be raised.
