conclusions the incidence of liver abscesses after liver cancer thermal ablation is low. child-pugh class b and class c cirrhosis, biliary tract disease, diabetes mellitus, and porta hepatis tumors are four significant risk factors. combined ablation and pei reduces the rate of liver abscesses. background radiofrequency ablation (rfa) and microwave ablation (mwa) are the most frequently used th...
5-FU is the drug most frequently used to treat biliary tract cancer, while dihydropyrimidine dehydrogenase (DPD) is known to be a principal factor in 5-FU drug resistance. However, whether DPD activity and mRNA levels correlate with response to 5-FU is unknown for biliary tract cancers. The precise mechanism of DPD regulation also remains to be elucidated. In the present study, we quantitativel...
BACKGROUND The incidence of pancreatic or biliary tract cancer is increasing in our aging population, but little is known of treatment outcomes in elderly patients with pancreatic or biliary tract cancer. PATIENTS AND METHODS Patients with pancreatic or biliary tract cancer who received chemotherapy in our institute between September 2007 and August 2009 were retrospectively reviewed to compa...
PURPOSE While tumor markers (carbohydrate antigen 19-9 [CA 19-9] and carcinoembryonic antigen [CEA]) can aid in the diagnosis of biliary tract cancer, their prognostic role has not been clearly elucidated. Therefore, this study was conducted to evaluate the prognostic role of tumor markers and tumor marker change in patients with advanced biliary tract cancer. MATERIALS AND METHODS Patients w...
p16Ink4 and p15Ink4B are cyclin-dependent kinase 4 inhibitors and link to the regulation of cell cycle in mammalian cells. The genes encoding these inhibitors are located at 9p21, which is a frequent site of allelic loss in various types of tumors. Twenty-five primary biliary tract cancers were examined for somatic mutations in p16Ink4/CDKN2, p15Ink4B/MTS2, p53, and K-ras genes and allelic loss...
OBJECTIVES Recent data show that the metabolic syndrome may play a role in several cancers, but the etiology for biliary tract cancer is incompletely defined. The present aim was to evaluate risk factors for biliary tract cancer in China. METHODS A case-control study in which cases were biliary tract cancer patients referred to Peking Union Medical College Hospital (PUMCH). Controls were rand...
BACKGROUND Inflammation was considered to perform crucial roles in the development and metastasis of malignancies. A heightened neutrophil-lymphocyte ratio has been described to be associated with detrimental survivals in different malignancies. Debate remains over the impact of heightened neutrophil-lymphocyte ratio on survivals in biliary tract cancer. The review evaluated the prognostic valu...
