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)
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)
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)
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 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)
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 metastasis. To(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)
OBJECTIVES The present study tried to identify factors predictive of upstaging from ultrasound-guided core needle biopsy (CNB)-diagnosed ductal carcinoma in situ (DCIS) to invasive cancer after surgical excision. MATERIALS AND METHODS We enrolled 506 female CNB-diagnosed DCIS patients who underwent subsequent surgical excision between January 2000 and(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)
We sought to determine the significance of Ki-67, one of the tumor cell proliferation markers, as a useful prognostic factor in early breast cancer. A total of 1080 consecutive patients with stage I or II breast cancer that underwent surgery between 1998 and 2003 were enrolled. Patients were categorized on the basis of the 2007 St. Gallen consensus and(More)
