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)
PURPOSE We have recently developed an endoscopic thyroidectomy using a gasless axillary approach and report the surgical outcome of the procedure. MATERIALS AND METHODS The gasless axillary approach was performed through a 3-cm axillary incision using a retractor instead of carbon dioxide insufflation. We performed a total of 35 thyroidectomies using this(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)
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). A total of 101 women (age range, 27–83 years) with pure DCIS that presented as mammographic calcifications were included.(More)
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. Ratios of visceral fat area (VFA) to subcutaneous fat area (SFA) were measured from the digital images of(More)
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). Data from 1558 consecutive patients diagnosed with IBC and/or(More)
PURPOSE To investigate the clinical effect of a single magnetic resonance (MR) imaging screening examination of the contralateral breast at preoperative evaluation in women with unilateral breast cancer. MATERIALS AND METHODS The institutional review board approved this study and waived informed consent. Among women with unilateral breast cancer who(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)
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)
As more patients undergo diagnostic thyroid surgery, the development of posthemithyroidectomy hypothyroidism is becoming a major concern. We hypothesized that the preoperative thyrotropin (thyroid-stimulating hormone, TSH) level and ultrasonographically measured thyroid volume, both commonly available in thyroid nodule patients, may predict the development(More)
