To identify putative tumor suppressor genes in hepatocarcinogenesis, we combined the representational difference analysis and reverse northern blot identifying downregulated genes in human hepatoma tissues. One of them was Dkk-3/REIC. Dkk-3/REIC was downregulated in 11 out of the 20 human hepatoma tissues as compared to their counterparts of noncancerous(More)
BACKGROUND Gastric subepithelial tumors are usually asymptomatic and observed incidentally during endoscopic examination. Although most of these tumors are considered benign, some have a potential for malignant transformation, particularly those originating from the muscularis propria layer. For this type of tumor, surgical resection is the standard(More)
AIM To identify the feasibility of the narrow-band imaging (NBI) method compared with that of conventional colonoscopy and chromoendoscopy for distinguishing neoplastic and nonneoplastic colonic polyps. METHOD This study enrolled consecutive patients who underwent colonoscopy using a conventional colonoscope between January and February 2006 at Chang-Gung(More)
BACKGROUND AND AIM Gallbladder (GB) polyps are tumor or tumor-like projections arising from GB mucosa. Although most polyps are benign, some early GB carcinomas present as polypoid lesions. The diagnosis of GB polyps is relatively easy by ultrasonography. Although numerous studies have investigated GB polyps, few studies have addressed the prevalence of and(More)
OBJECTIVES There is no reliable parameter to predict the late mortality of patients with severe acute pancreatitis though it is an important issue. Recently a proposed parameter for "immunoparalysis," a down-regulation of Human Leukocytes Antigens-DR (HLA-DR) expression on monocytes, had been detected in patients with severe but not mild acute pancreatitis.(More)
A cohort of patients with intraductal growth-type intrahepatic cholangiocarcinoma (IG-ICC) and its precursor lesions, collectively termed intraductal papillary neoplasm of the liver (IPNL), was characterized with respect to demographics, clinical manifestations, perioperative management, long-term survival, and molecular features associated with(More)
AIM To investigate the outcomes, as well as risk factors for 6-wk mortality, in patients with early rebleeding after endoscopic variceal band ligation (EVL) for esophageal variceal hemorrhage (EVH). METHODS Among 817 EVL procedures performed for EVH between January 2007 and December 2008, 128 patients with early rebleeding, defined as rebleeding within 6(More)
Kaposi's sarcoma (KS) is an uncommon malignant neoplasm of mesenchymal tissue that occurs in immunocompromised patients and people of Mediterranean descent. It is most common in males, and skin lesions are usual presentations. However, visceral lesions are common in organ transplant recipients and involve the gastrointestinal tract. Although the(More)
OBJECTIVE To propose a cholangiographic classification for intraductal growth type intrahepatic cholangiocarcinoma (IG-ICC) and its precursor, collectively termed intraductal papillary mucinous neoplasm of the bile ducts (IPMN-B). SUMMARY BACKGROUND DATA For the extensive clinicopathologic variations of IPMN-B, a detailed characterization of(More)
BACKGROUND Surgery of gastrointestinal stromal tumors (GISTs) has been modified, and laparoscopic resection of GIST has gained improvement and roles. PATIENTS AND METHODS We retrospectively reviewed clinical data and oncological outcomes of our GIST patients who underwent laparoscopic surgery and traditional open surgery. In total, 227 pathologically(More)
