【 摘 要 】

We investigated the clinicopathologic and oncoprotein expression characteristics of 11 pure mucinous and 76 non-mucinous infiltrating ductal carcinomas in the human female breast. We compared patient age, tumor size, axillary lymph node status, and the expression of estrogen receptor (ER), progesterone receptor (PR), deleted-in-colon cancer (DCC), HER-2/neu, and p53. Mucinous carcinoma with axillary lymph node metastasis occurs less frequently than non-mucinous carcinoma (0% vs 63.1%; p = 0.0018). Compared with the non-mucinous type, mucinous carcinoma specimens have more DCC expression (100% vs 48.7%; p = 0.0027) and more ER expression (90.9% vs 26.9%; p = 0.0023), but less HER-2/neu overexpression (0% vs 38.1%; p = 0.0302). We confirmed that mucinous carcinoma samples from the breast reveal distinct clinicopathologic and oncoprotein expression features compared with non-mucinous carcinoma and, therefore, it seems reasonable to suggest different biologic characteristics and manifestations.
