Management of ductal carcinoma in situ (DCIS) has evolved from radical surgery to the option of a more minimally invasive approach. Data show that breast conservation surgery performed with administration of radiotherapy, like mastectomy, is feasible and safe. Because efforts to find a safe group for elimination of radiotherapy have resulted in data that conflict, radiotherapy still remains sta...

The transition from ductal carcinoma in situ to invasive ductal carcinoma is a key event in breast cancer progression that is still not well understood. To discover the microRNAs regulating this critical transition, we used 80 biopsies from invasive ductal carcinoma, 8 from ductal carcinoma in situ, and 6 from normal breast. We selected them from a recently published deep-sequencing dataset [Fa...

CONTEXT AND OBJECTIVE Breast cancer is thought to derive from progressively aberrant, non-invasive breast lesions, but it is not known exactly how invasive breast cancer develops from these lesions. The aim of this study was to verify the changes in c-erbB-2 and p53 protein expression between non-neoplastic ducts, ductal carcinoma in situ and invasive ductal carcinoma found in the same breast. ...

Dual malignancy was first reported by Billroth in 1889. Incidence of second malignancy in cancer patients is as high as 10%, but synchronous anaplastic thyroid cancer along with breast tumor is a rare entity. We present a case of a 61-year-old female with a synchronous anaplastic carcinoma thyroid with ductal carcinoma breast. The plausible association of breast cancers with thyroid carcinomas ...

We report on two cases where breast magnetic resonance imaging examination changed clinical management. Breast magnetic resonance imaging is now recognised as an indispensable adjunctive examination to mammography and ultrasound. In each of the two cases described, breast magnetic resonance imaging revealed unsuspected, extensive, and mammographically and ultrasonologically occult, ductal carci...

Juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. The development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. We encountered a 36-year-old woman with a palpable mass in the right breast. The radiologic findings were indicative of a fibroadenoma in the breast. Sonographic guided ...

BACKGROUND Ductal carcinoma in situ (DCIS) is a malignant proliferation of ductal epithelium confined by the basement membrane of the involved breast ducts. The aim of this study was to categorize positive findings of DCIS of the breast on sonography. METHODS From 2007 to 2011, 100 pathologically proven DCIS lesions were evaluated. Four sonographic patterns used to identify DCIS have been cha...

Chromogenic in situ hybridization (CISH) has shown the potential to replace fluorescence in situ hybridization (FISH) to determine HER2 gene status. To validate the reliability of CISH, we used 226 consecutive breast carcinomas from 2 institutions and tested CISH and FISH on the same tumor set simultaneously at different test sites. Besides manufacturers' scoring criteria, the new American Soci...

The early proliferative lesions of the breast have taken on greater significance as a result of mammographic screening and the use of even more sensitive imaging technologies. The intraductal proliferative lesions of the breast are a group of cytologically and architecturally diverse proliferations, typically originating from the terminal duct-lobular unit and confined to the mammary duct-lobul...
