BACKGROUND The need for new prognostic factors in breast cancer is ever increasing as breast cancer management evolves. Aberrant DNA methylation plays a pivotal role in cancer development and progression; DNA methylation-based biomarkers may provide independent prognostic information. We used pyrosequencing to investigate the prognostic potential of(More)
Adenomyoepithelioma (AME) of the breast is an uncommon tumor characterized by its dual differentiation into luminal cells and myoepithelial cells. In most cases these tumors have a benign clinical course, but distant metastases have been reported. We present the case of a 51-year-old woman diagnosed with malignant AME. The patient underwent a right modified(More)
BACKGROUND The principal objective of this study was to assess clinical outcomes by breast cancer subtype in patients with brain metastases. METHODS Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) status was evaluated via immunohistochemical staining. Four survival time intervals were compared(More)
In this study, we characterized two blocks of minisatellites in the 5' upstream region of the BORIS gene (BORIS-MS1, -MS2). BORIS-MS2 was found to be polymorphic; therefore, this locus could be useful as a marker for DNA fingerprinting. We assessed the association between BORIS-MS2 and breast cancer by a case-control study with 428 controls and 793 breast(More)
PURPOSE To assess the value of screening ultrasonography (US) in the detection of nonpalpable locoregional recurrence following mastectomy for breast cancer and to describe the US appearances of occult recurrent cancers. MATERIALS AND METHODS During a 36-month period, 1180 consecutive US screenings were performed for mastectomy sites and ipsilateral(More)
To gain molecular understanding of carcinogenesis of breast cancer, gene expression profiles were analyzed using cDNA microarray representing 4,600 cDNAs in 10 breast cancer samples and the adjacent noncancerous breast tissues from the same patients. The alterations in gene expression levels were confirmed by reversetranscription PCR in four randomly(More)
We present a case of a 77-year-old female who had a metaplastic breast carcinoma with extensive osseous differentiation. Her mammogram showed a largely calcified mass, but the pathology revealed that the calcification was ossification. The radiologic differentiation between an osteoid matrix and a dense calcification is discussed. Radiologic and pathologic(More)
