In a three-stage genome-wide association study among East Asian women including 22,780 cases and 24,181 controls, we identified 3 genetic loci newly associated with breast cancer risk, including rs4951011 at 1q32.1 (in intron 2 of the ZC3H11A gene; P=8.82×10(-9)), rs10474352 at 5q14.3 (near the ARRDC3 gene; P=1.67×10(-9)) and rs2290203 at 15q26.1 (in intron(More)
BACKGROUND CX3CL1 is the only CX3C chemokine that can chemoattract T cells, natural killer (NK) cells, and dendritic cells (DCs). The role of CX3CL1 in breast carcinoma remains unknown. METHODS Immunohistochemical staining for CX3CL1, CD8, CD57, and CD1a was performed on 204 breast carcinoma specimens using tissue microarray blocks to determine whether(More)
Paget disease is a rare malignancy of the breast characterized by infiltration of the nipple epidermis by adenocarcinoma cells. The clinical features of Paget disease are characteristic and should increase the likelihood of the diagnosis being made. An important point is that more than 90% of cases of Paget disease are associated with an additional(More)
PURPOSE Lymphovascular invasion (LVI) is an important prognostic factor in patients with lymph node-negative patients with invasive breast cancer. However, the prognostic value of LVI it is unclear and controversial about its prognostic value in patients with lymph node-positive breast cancer patients. So, we report the an analysis of the prognostic(More)
Mammary phyllodes tumors (PTs) are uncommon fibroepithelial neoplasms. On the basis of histologic criteria, PTs can be divided into benign, borderline, and malignant groups; however, the histologic distinction of PTs is often difficult and arbitrary. In breast cancer, promoter hypermethylation is a common phenomenon, but there are no data available(More)
OBJECTIVE The objective of our study was to describe the MRI findings of medullary carcinoma of the breast and to correlate those findings with the histopathologic findings. MATERIALS AND METHODS From January 2005 to June 2010, MR images of 15 patients (age range, 32-73 years; mean age, 50 years) with pathologically confirmed medullary carcinoma of the(More)
Recent microarray profiling studies on breast cancer have identified distinct subtypes that are associated with different clinical outcomes. Promoter hypermethylation of several known or putative tumor suppressor genes occurs frequently during the pathogenesis of breast cancer. We proposed that immunohistopathologic subtypes of breast cancer are likely to(More)
To investigate the diagnostic potential of DNA methylation-based markers in tissue samples of DCIS, we examined the prevalence and extent of methylation in breast ductal carcinoma in situ (DCIS) samples from North American and Korean women. Quantitative multiplex-methylation specific PCR (QM-MSP) of ten genes was performed. The methylation level of APC1,(More)
Enhancer of zeste homolog 2 (EZH2) catalyzes trimethylation of histone H3 lysine 27 (H3K27me3) and its demethylation is catalyzed by UTX. EZH2 levels are frequently elevated in breast cancer and have been proposed to control gene expression through regulating repressive H3K27me3 marks. However, it is not fully established whether breast cancers with(More)
OBJECTIVE To analyze the magnetic resonance (MR) imaging findings of invasive micropapillary carcinoma of the breast. MATERIALS AND METHODS MR images were retrospectively evaluated in 14 patients (age range: 37-67, mean age: 49 years) with pathologically confirmed invasive micropapillary carcinoma of the breast. The enhancement type (mass/non-mass),(More)
