The relationship between ductal and lobular breast carcinoma is highlighted in cases in which these morphologically divergent carcinomas coexist in proximity within a single patient. We hypothesized that such cases may result from the proliferation of a precursor lesion into a tumor containing areas of divergent morphologic features. In this study, we analyzed loss of heterozygosity (LOH) in 10...
Ductal carcinoma in situ (DCIS) is a breast (BC) consisting of malignant cells the ductal lumen without invasion beyond epithelial membrane. The article presents rare clinical case combined course chronic mastitis and 47-year-old female patient who was diagnosed with during instrumental examination, only after trepan biopsy subsequent histological intraductal cancer verified. This may indicate ...
BACKGROUND There has been growing interest in the overdiagnosis of breast cancer as a result of mammography screening. We report incidence rates in British Columbia before and after the initiation of population screening and provide estimates of overdiagnosis. METHODS We obtained the numbers of breast cancer diagnoses from the BC Cancer Registry and screening histories from the Screening Mamm...
background: ultrasound propagation velocity was measured experimentally in normal, fibroadenoma and ductal carcinoma breast tissues, in order to distinguish normal breast tissue from tumors. materials and methods: in quantitative measurements of ultrasound velocity, 403 breast tissue images were selected, comprising 130 normal breast tissue, 130 fibroadenoma, and 143 ductal carcinoma tumors. th...
PURPOSE Normal epithelial cell specific-1 (NES1)/kallikrein 10 gene is expressed in normal mammary and prostate epithelial cells, but the expression of NES1 mRNA and protein is markedly reduced in established breast and prostate cancer cell lines although the NES1 gene is intact. Here, we wished to assess whether NES1 expression is down-regulated in primary breast cancers. EXPERIMENTAL DESIGN...
Introduction: Breast cancer is the second most common cause of cancer-related death among females, which requires an exploration for markers to propose a more specific categorization of this cancer. Long noncoding RNAs (lncRNAs), the main subset of noncoding transcripts, are involved in tumorigenic processes. In this study, we investigated the expression of the fer-1–like family member 4 (FER...
BACKGROUND Breast cancer screening and higher quality mammography have resulted in an increase in the diagnosis of ductal carcinoma in situ worldwide. We compared the incidence and other factors in our cases of ductal carcinoma in situ between two recent decades. MATERIALS AND METHODS Medical records of cases of ductal carcinoma in situ who had been admitted to the surgery wards of the Cancer...
