GOALS To compare the efficacy of radiofrequency ablation (RFA) and surgical resection in a group of patients with a Child-Pugh score of 5 and a single HCC less than 4 cm in diameter. BACKGROUND Radiofrequency ablation (RFA) has become a popular method for treatment of hepatocellular carcinoma (HCC) and has been applied as an alternative primary therapy to(More)
We investigated the overall and site-specific prevalence of pre-S mutations and its clinical significance in patients with genotype C hepatitis B virus (HBV) infection. Three hundred subjects were included: 50 asymptomatic carriers (AC), 87 chronic hepatitis (CH), 91 liver cirrhosis (LC) and 72 hepatocellular carcinoma (HCC). Pre-S mutations were determined(More)
BACKGROUND AND AIMS Epidemiologic studies provide evidence for a link between obesity or diabetes and the risk for colorectal cancer. However, there is a lack of information about the relationship between metabolic syndrome and colorectal adenoma. Therefore, we investigated whether metabolic syndrome is a risk factor for colorectal adenoma. METHODS We did(More)
BACKGROUND AND AIM Although increased mast cells in the gut and their role in visceral hypersensitivity in irritable bowel syndrome have been postulated, this relationship remains unclear. Our aim was to determine whether a relationship exists between the number of mucosal mast cells in the gut and visceral hypersensitivity. METHOD Eighteen patients with(More)
We studied the expression of maspin in colonic adenocarcinoma compared with adenoma and metastatic adenocarcinoma as well as the relationship with its possible regulator, p53. The colonic specimens consisted of 24 adenomas, 49 adenocarcinomas, and 17 metastatic adenocarcinomas. Immunohistochemical staining of paraffin sections was done with microwave-based(More)
BACKGROUND To achieve en bloc resection for large lesions, endoscopic mucosal resection after circumferential precutting and endoscopic submucosal dissection techniques have been developed. AIM To compare endoscopic submucosal dissection with endoscopic mucosal resection after circumferential precutting in terms of the clinical efficacy and safety. (More)
BACKGROUND AND STUDY AIMS Since gastric adenomas are precancerous lesions, polypectomy is necessary. However, there have been no reports suggesting factors capable of predicting malignant transformation of gastric adenomas removed by endoscopic snare polypectomy (ESP) or endoscopic mucosal resection (EMR) in Korea, a country in which gastric cancer is a(More)
BACKGROUND Clinicopathologic features and prognosis of combined hepatocellular cholangiocarcinoma (HCC-CC) have not been established. METHODS Data of patients who underwent surgical resection for HCC-CC were compared with those of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (CC) patients. RESULTS The prevalence of hepatitis B(More)
BACKGROUND Although endoscopic resection can provide a wide tumor resection with a negative resection margin, it is not yet recommended as a curative therapy for ampulla of Vater cancer. METHODS To investigate the microinvasion rate and the diagnostic accuracy of endoscopic biopsy to properly judge the safety of endoscopic resection for ampulla of Vater(More)
BACKGROUND AND AIM Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. However, the clinical features of young HCC patients have not been fully studied. In the present study, we investigated the prevalence, clinical characteristics and prognosis of young HCC patients. METHODS A retrospective analysis was performed for HCC patients(More)
