The impact of different carcinogenic exposures on the specific patterns of somatic mutation in human tumors remains unclear. To address this issue, we profiled 209 cholangiocarcinomas (CCAs) from Asia and Europe, including 108 cases caused by infection with the liver fluke Opisthorchis viverrini and 101 cases caused by non-O. viverrini-related etiologies.(More)
BACKGROUND Up-regulation of vitamin D receptor (VDR) expression has been shown in several tumors and is thought to represent an important endogenous response to tumor progression. The authors aimed to verify the expression of VDR and its clinical significance in histologically proven cholangiocarcinoma (CCA). METHODS The antiproliferative activity of(More)
MicroRNA, an endogenous noncoding RNA modulating gene expression, is a key molecule that by its dysregulation plays roles in inflammatory-driven carcinogenesis. This study aimed to investigate the role of oncomiR miR-21 and its target, the programmed cell death 4 (PDCD4) in tumor growth and metastasis of the liver fluke Opisthorchis viverrini-associated(More)
Postmortem tissues are frequently used in forensic investigation, clinical studies, and biomedical research. It is well known that the shorter period from death to analyses provides the more accurate results. However, the longest postmortem interval that still provides the reliable data remains unclear. We performed serial analyses of postmortem changes in(More)
BACKGROUND This study aimed to investigate the miR-192 levels in patients' sera of liver fluke-associated cholangiocarcinoma (CCA) for a prospective prognostic indicator. METHODS MicroRNA polymerase chain reaction (PCR) array was performed using pooled serum samples from 11 CCA patients and nine healthy subjects. Selected miRNAs were verified for the(More)
BACKGROUND Liver cancer is the most frequent cancer among Thais especially people in northeastern Thailand, but there has as yet been no assessment of trend. The data of all cancers in Khon Kaen can be retrieved from data base of the Khon Kaen Cancer Registry (KKCR) which was established in 1984. OBJECTIVE To assess the incidence trend of hepatocellular(More)
Opisthorchis viverrini infection induces chronic inflammation in the bile ducts, leading to periductal fibrosis (PDF), which possibly associates to cholangiocarcinoma (CCA). Patients with CCA have a poor prognosis, which is linked to asymptomatic disease and late diagnosis. Hence, detecting early stage CCA is essential. Secretory miRNAs have been promoted(More)
BACKGROUND AND AIM Cholangiocarcinoma patients usually have poor treatment outcome and a high mortality rate. The role of adjuvant chemotherapy (AC) is controversial. Our study aimed to evaluate benefits of AC in resectable cholangiocarcinoma patients. METHODS A retrospective study included 263 patients who underwent curative resection in Srinakarind(More)
AIM High levels of serum sialyl Lewis(a) (sLea) are frequently found in cholangiocarcinoma (CCA) patients and have been suggested to be a serum marker for CCA. However, the significance of this antigen in CCA is unknown. In this study, the clinical significance of sLea expression in CCA tissues and the possible role of sLea in vascular invasion in vitro(More)
Surgical resection is the gold standard treatment and is considered the only potential cure for cholangiocarcinoma (CCA). However, most of the patients present at a late stage of disease and positive margins are frequently encountered. Therefore, adjuvant therapeutic modalities, such as chemotherapy and/or radiotherapy are needed to improve the survival(More)
