The aim was to compare the expression of MUC1 and carbohydrate antigens in 124 tissue samples; 42 fibroadenoma (FA), 23 nonproliferative benign diseases (NPF), 25 usual epithelial hyperplasia (UEH), 7 atypical ductal hyperplasia (ADH), and 27 breast normal tissues. An immunohistochemical approach was adopted, using the following antibodies: reactive with(More)
AIM A descriptive study was developed in an entire Argentine rural community considering breast cancer risk factors, preventive strategies and breast cancer incidence. PATIENTS AND METHODS the study comprised of 83 women. A questionnaire of 34 items was employed; a mammogram and a breast ultrasound were performed. ANOVA and Pearson correlation were(More)
OBJECTIVE In breast cancer, several tumor markers have been identified. The marker most extensively associated with breast cancer is MUC1. The objective of the study was to analyze prognostic and risk factors in relation to tumor markers in order to clarify breast cancer biology. A total of 349 primary tumor samples and lymph nodes from breast cancer(More)
Breast cancer is the most common cause of cutaneous metastases from internal malignancies. Generally, the neoplastic cells are located in the dermis or hypodermis, while a finding of transepidermal elimination on cutaneous metastases is exceptional. In this report we present a patient with perforating cutaneous metastases from breast cancer with mucin 1(More)
BACKGROUND The glycoprotein MUC1 is overexpressed and underglycosylated in cancer cells. MUC1 is translated as a single polypeptide that undergoes autocleavage into 2 subunits (the extracellular domain and the cytoplasmic tail), and forms a stable heterodimer at the apical membrane of normal epithelial cells. The MUC1 cytoplasmic tail localizes to the(More)
