Microinvasion of High-Grade Pancreatic Intraepithelial Neoplasia
High-grade pancreatic intraepithelial neoplasia (PanIN-3) is recognized as a precursor lesion of invasive ductal carcinoma (IDC). However, histological evidence that PanIN-3 invades beyond the basement membrane of pancreatic ductal epithelium, that is, the moment PanIN-3 becomes IDC, has not been captured yet. This may be because PanINs which are microscopic papillary or flat lesion rarely deve...
متن کاملDifferential cell cycle and proliferation marker expression in ductal pancreatic adenocarcinoma and pancreatic intraepithelial neoplasia (PanIN).
AIMS Pancreatic cancer is an aggressive tumour following a multistep progression model through precursors called pancreatic intraepithelial neoplasia (PanIN). Identification of reliable prognostic markers would help in improving survival. The aim of this study was to investigate the role as well as the prognostic significance of different cell cycle and proliferation markers, namely p21, p27, p...
متن کاملOverexpression of fibroblast growth factor receptor 4 in high-grade pancreatic intraepithelial neoplasia and pancreatic ductal adenocarcinoma.
The overexpression of fibroblast growth factor receptor (FGFR) 4 has been reported in various human cancers, but it has not been studied in pancreatic ductal adenocarcinoma (PDAC) or its precursor lesion, pancreatic intraepithelial neoplasia (PanIN). Moreover, there is controversy as to whether FGFR4 has a mitogenic role in carcinogenesis or other functions. Therefore, the expression and roles ...
متن کاملHigh-Grade Prostatic Intraepithelial Neoplasia
High-grade prostatic intraepithelial neoplasia (HGPIN) has been established as a precursor to prostatic adenocarcinoma. HGPIN shares many morphological, genetic, and molecular signatures with prostate cancer. Its predictive value for the development of future adenocarcinoma during the prostate-specific antigen screening era has decreased, mostly owing to the increase in prostate biopsy cores. N...
متن کاملPeriampullary localized pancreatic intraepithelial neoplasia-3 (PanIN-3): evaluation with contrast-enhanced MR cholangiography (MRCP)
BACKGROUND The early determination of premalignant lesions of pancreas can prevent unnecessary excessive surgical procedures and can reduce morbidity and mortality. Pancreatic intraepithelial neoplasia-3 (PanIN-3) is a preinvasive form of adenocarcinoma (carcinoma in situ). PanINs have not taken place in the literature of radiology yet, it should be considered in differential diagnosis of pancr...
