Shear wave elastography (SWE) is an emerging technique which can obtain quantitative elasticity values in breast disease. We therefore evaluated the diagnostic performance of SWE for the differentiation of breast masses compared with conventional ultrasound (US). Conventional US and SWE were performed by three experienced radiologists for 158 consecutive(More)
BACKGROUND Recently identified genetic variants from genome-wide association studies (GWAS) on breast cancer have not been validated in Asian populations, except in China. In this study, we sought to confirm the association between known variants and breast cancer in Korean women and further evaluate the associations of individual single nucleotide(More)
PURPOSE The association between body mass index and breast cancer outcome is controversial. Furthermore, the impact of underweight on breast cancer recurrence and death has not been adequately addressed. PATIENTS AND METHODS We investigated this issue using a large nationwide database of 24,698 Korean breast cancer patients. The association between body(More)
Anti-estrogen therapy has been shown to reduce mammographic breast density (MD). We hypothesized that a short-term change in breast density may be a surrogate biomarker predicting response to adjuvant endocrine therapy (ET) in breast cancer. We analyzed data for 1,065 estrogen receptor (ER)-positive breast cancer patients who underwent surgery between 2003(More)
BACKGROUND Our aim was to compare the accuracy of magnetic resonance imaging (MRI) and ultrasonography (US) in measuring the size of invasive breast cancer (IBC) and carcinoma in situ (CIS). We also examined the utility of routinely performing MRI in addition to US before breast-conserving surgery (BCS). PATIENTS AND METHODS Data from 1558 consecutive(More)
OBJECTIVE This study investigated the correlation of oestrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2) status with the probability of malignancy (POM) of mammographic calcifications in ductal carcinoma in situ (DCIS). METHODS A total of 101 women (age range, 27-83 years) with pure DCIS that presented as mammographic(More)
Understanding the molecular background of breast cancer biology is critical in developing new biomarkers for earlier diagnosis and more optimized treatment. We performed a proteomic analysis of human breast carcinoma tissues to investigate the tumor-specific protein expression in breast carcinoma. Using 2-dimensional electorphoresis (2-DE) and(More)
PURPOSE Obesity is closely related to the development of colorectal cancer as well as other metabolic complications. We investigated the prognostic significance of visceral obesity and body mass index (BMI) in 161 resectable colorectal cancer patients. METHODS Ratios of visceral fat area (VFA) to subcutaneous fat area (SFA) were measured from the digital(More)
BACKGROUND The aim of this study was to develop a new data-mining model to predict axillary lymph node (AxLN) metastasis in primary breast cancer. To achieve this, we used a decision tree-based prediction method-the alternating decision tree (ADTree). METHODS Clinical datasets for primary breast cancer patients who underwent sentinel lymph node biopsy or(More)
INTRODUCTION Inflammation has been implicated in cancer aggressiveness. As transglutaminase 2 (TG2), which has been associated with inflammatory signaling, has been suggested to play a role in tumor behavior, we propose that TG2 may be an important linker inducing interleukin (IL)-6-mediated cancer-cell aggressiveness, including distant hematogenous(More)
