Magnetic resonance imaging (MRI) has been used for the local staging of breast cancer, especially to determine the extent of multiple lesions and to identify occult malignancies. The aim of this study was to evaluate the effect of pre-operative MRI on the surgical treatment of breast cancer. Between January 2006 and May 2007, 535 newly diagnosed breast(More)
BACKGROUND Recently PET is emerged as a method to estimate the response of neoadjuvant chemotherapy (NAC) in advanced breast cancer. This study is aimed to estimate the predictive role of PET CT and other imaging modalities (ultrasound, MRI) through NAC. METHODS PET CT was acquired before and after NAC from 41 patients. Pathologic results were classified(More)
BACKGROUND The purpose of this study was to determine the effectiveness of oral calcium plus vitamin D supplementation and to compare the effects of cholecalciferol versus calcitriol treatments on postoperative hypocalcemia. METHODS After total thyroidectomy with central neck dissection, 306 patients were divided into 4 groups according to "routine use(More)
AIM Occult lymph node metastasis is common in differentiated thyroid cancer (DTC). However, the role of lymph node dissection in the treatment of DTC remains controversial. The authors investigated the usefulness of methylene blue dye only method and combined radioisotope and methylene blue dye method for detecting SLN and compared the values of these two(More)
The number of epidermal growth factor receptors (EGFRs) and their ligands are highly expressed in malignant tumor cells. The EGF signaling pathway is also activated in up to one-third of patients with breast cancer. In this study, we investigated the novel function of the JAK3 inhibitor, WHI-P131, on EGF-induced MMP-9 expression and the regulatory mechanism(More)
In order to establish optimal management for aortoenteric fistula (AEF) the records of five patients treated for AEF (four aortoduodenal and one aortogastric fistula) were retrospectively reviewed. The arterial reconstruction procedures were selected according to the surgical findings, underlying cause, and patient status. In situ aortic reconstructions(More)
Matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) expression are pivotal steps in cancer metastasis. Herein, we investigated the effect of silibinin, a major constituent (flavanolignan) of the fruits of Silybum marianum, on 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced MMP-9 and VEGF expression in MCF-7 human breast(More)
Controversy surrounds appendectomy timings and their effects on postoperative outcomes. This study evaluated the influence of hospital delays on perforation rates and complications in patients with acute appendicitis. From January 2008 to December 2013, the cases of 4148 consecutive patients who had undergone appendectomies for suspected appendicitis were(More)
BACKGROUND/AIMS Intraoperative cholangiogram (IOC) during laparoscopic cholecystectomy (LC) has been used to evaluate bile duct stone. But, the routine use of IOC remains controversial. With routine IOC during LC, we reviewed the variation of hepatic duct confluence and try to suggest the diagnostic criteria of asymptomatic common bile duct (CBD) stone. (More)
