Cholagiocarcinoma

BACKGROUND: An in-patient presented with atypical primary liver mass and was suspected of having liver metastasis. One method of investigation is colonoscopy; however, there are currently no clear guidelines to indicate when this procedure should be performed. MATERIAL AND METHOD: This was a retrospective review of 6 years' data from the surgical endoscopic unit in Rajavithi Hospital. The inclusion criteria were: (1) patient presented with liver mass, (2) radiological findings (mainly from CT scan or MRI) were not typicalfor hepatocellular carcinoma (HCC), intrahepatic cholagiocarcinoma (ICGC) and other primary liver tumors...

BACKGROUND: Cancer-testis antigens (CTAs) are suitable targets for cancer-specific immunotherapy. The aim of the study is to investigate the expression of CTAs in intrahepatic cholagiocarcinoma (IHCC) and evaluate their potential therapeutic values. METHODS: Eighty-nine IHCC patients were retrospectively assessed for their expression of CTAs and HLA Class I by immunohistochemistry using the following antibodies: MA454 recognizing MAGE-A1, 57B recognizing multiple MAGE-A (MAGE-A3/A4), E978 recognizing NY-ESO-1, and EMR8-5 recognizing HLA class I...

Hilar cholangiocarcinoma (HC) is a rare tumor which has to be distinguished by intrahepatic cholagiocarcinoma invading hepatic hilum because the former has better prognosis then the latter. Patients with HC are difficult to manage because many challenging issues remain in the treatment of this tumour regarding correct diagnosis and therapeutic strategy. HC is resectable in about 30% of cases, but operative risk is highly influenced by septic complications of preoperative biliary drainage and by the need of major liver resection associated with biliary resection...

Acute hepatitis A virus (HAV) infection is frequent in developing countries. Although some gallbladder abnormalities are defined during the course, an acute cholecystitis is extremely rare. We here report 2 additional cases of cholecystitis due to acute HAV infection and review the previously reported 2 cases. One of our patients was admitted with jaundice and a suspicious portal mass with a presumed diagnosis of cholagiocarcinoma. The other presented with jaundice, abdominal pain, and constitutional symptoms...

The long-term effects of thorotrast administration include local granulomas, blood cell abnormalities, and cancer. To date, more than 100 cases of liver cancer have been reported in patients previously given this radioactive contrast material, with a latency period of approximately 22 years. We report such a case; the patient not only had a thorotrast-induced cholangiocarcinoma, but also showed striking morphologic changes in the red blood cells secondary to splenic dysfunction.
