S100P immunostaining identifies a subset of peripheral‐type intrahepatic cholangiocarcinomas with morphological and molecular features similar to those of perihilar and extrahepatic cholangiocarcinomas Aims: S100P is a calcium‐binding protein that is frequently expressed in pancreatic adenocarcinoma and perihilar cholangiocarcinoma. The aim of this study was to investigate the pathological significance of the expression of S100P in peripheral intrahepatic cholangiocarcinoma (ICC). Methods and results: Immunohistochemical staining was used to investigate S100P expression in 112 cases of peripheral ICC. The results were compared with those for perihilar and extrahepatic cholangiocarcinomas. Patients with S100P‐positive peripheral ICC were more likely to have elevated serum levels of carcinoembryonic antigen (CEA) and CA19‐9 than those with S100P‐negative peripheral ICCs. All cases of peripheral ICC associated with intrahepatic lithiasis and all cases with intraductal/periductal growth patterns were positive for S100P. S100P‐positive peripheral ICCs were highly associated with ‘bile duct’ morphology rather than cholangiolar differentiation. Nearly all cases of perihilar and extrahepatic cholangiocarcinoma were positive for S100P. Similarly to perihilar and extrahepatic cholangiocarcinomas, S100P‐positive peripheral ICCs showed more frequent expression of CEA and MUC2, and were more likely to be N‐cadherin‐negative, than S100P‐negative cases. Notably, K‐RAS mutations were only detected in S100P‐positive peripheral ICCs, with a frequency similar to that in perihilar and extrahepatic cholangiocarcinomas. Patients with S100P‐positive peripheral ICC were more likely to have poor prognoses than those with S100P‐negative tumours. Conclusions: S100P immunostaining identifies a subset of peripheral ICC that probably originates from larger bile ducts. This subset of peripheral ICCs shares common morphological and molecular features with perihilar and extrahepatic cholangiocarcinomas.

Analysis of parametric histogram from dynamic contrast‐enhanced MRI: application in evaluating brain tumor response to radiotherapy

Dynamic contrast‐enhanced MRI (DCE MRI) has been used to study tumor response to treatment for many years. In this study, the modified full width at half‐maximum (mFWHM), calculated from the wash‐in slope histogram, is proposed as a parameter for the evaluation of changes in tumor heterogeneity which respond to radiotherapy. Twenty‐five patients with brain tumors were evaluated and divided into the nonresponder group (n = 11) and the responder group (n = 14) according to the Response Evaluation Criteria in Solid Tumors (RECIST). All selected tumors were evaluated by mFWHM ratios of post‐ to pre‐therapy (the ratio was defined as the therapeutic mFWHM ratio, TMR). The changes in kurtosis of the histograms and the averaged K^trans within a tumor were also calculated for comparison. The receiver operating characteristic analysis and Kaplan–Meier curves were used to examine the diagnosis ability. The TMR values were significantly higher in nonresponders than in responders (p < 0.001). When compared with the other two parameters, the proposed method also demonstrated better sensitivity and specificity. When adopting the TMR for the estimation of prognosis after therapy, there was a significant difference between the population survival curves. In conclusion, the derived mFWHM reflects tumor heterogeneity, and the ability to depict patient survival probability from TMR corresponds well with that from RECIST. The results reveal that, in brain tumors, progression may be exhibited not only by tumor size, but also by tumor heterogeneity. Copyright © 2012 John Wiley & Sons, Ltd.     

MiR-124-3p suppresses glioma aggressiveness via targeting of Fra-2

Malignant glioma is the most common and deadly primary brain tumor in adults. However, the mechanisms underlying the malignancy of glioma remain unclear. In the present study, we found that Fos-related antigen-2 (Fra-2) was overexpressed in most glioma cells, and knockdown of Fra-2 prevented cell proliferation, migration, and invasion. Mechanistically, Fra-2 silencing led to a significant reduction in cell-cycle drivers (Cyclin D1 and Cyclin E1), one invasion-associated gene (MMP9), the mesenchymal marker (Vimentin), and induction of the epithelial marker (E-cadherin). Further study confirmed that miR-124-3p decreased the expression of Fra-2 via directly targeting the 3′-UTR, and transfection with miR-124-3p in glioma cells inhibited expression of the above cell-cycle and EMT promoters. Phenotypic experiments also showed that overexpression of Fra-2 weakened the inhibitory effects of miR-124-3p on the proliferation, migration, and invasion of glioma cells. In addition, Fra-2 knockdown impaired the malignant phenotypes enhanced by miR-124-3p inhibition, which suggested a crucial role for the miR-124-3p/Fra-2 pathway in glioma development. Consistently, high expression of Fra-2 was closely associated with low miR-124-3p level and indicated a poor prognosis in patients with glioma. In conclusion, this study indicates the existence of an aberrant miR-124-3p/Fra-2 pathway that results in glioma aggressiveness, which suggests novel therapeutic opportunities for this fatal disease.
