abstract = {Deleted in malignant brain tumours 1 (DMBT1) exerts
functions in the regulation of epithelial differentiation
and inflammation and has been proposed as a tumour
suppressor. Because chronic inflammation is a hallmark of
cholangiocarcinogenesis, the aim of this study was to
investigate the expression of DMBT1 in biliary tract cancer
(BTC) and to correlate this expression with
clinicopathological data.The expression of DMBT1 protein was
examined immunohistochemically in 157 BTC patients [41
intrahepatic (ICC), 60 extrahepatic cholangiocarcinomas
(ECC) and 56 adenocarcinomas of the gallbladder (GBAC)].
Additionally, 56 samples of high-grade biliary
intraepithelial neoplasia (BilIN 3) and 92 corresponding
samples of histological non-neoplastic biliary tract tissues
were included. DMBT1 expression was increased significantly
in BilIN 3 compared to normal tissue (P < 0.0001) and BTC (P
< 0.0001). BTC showed no significant difference in DMBT1
expression compared to non-neoplastic biliary tissue (P =
0.315). Absent DMBT1 expression in non-neoplastic biliary
tissue of BTC patients was associated with poorer survival
(P = 0.027). DMBT1 expression was correlated significantly
with patients' age (P < 0.001).DMBT1 is expressed
differently in cholangiocarcinogenesis and poorer patients'
survival rates are associated with absent DMBT1 expression
in non-neoplastic biliary tissue, suggesting a
tumour-suppressive role of DMBT1 in early
cholangiocarcinogenesis.},
