PIK3CA mutations in intraductal papillary mucinous neoplasm/carcinoma of the pancreas.
PURPOSE Recent studies have reported high frequencies of somatic mutations in the phosphoinositide-3-kinase catalytic-alpha (PIK3CA) gene in various human solid tumors. More than 75% of those somatic mutations are clustered in the helical (exon 9) and kinase domains (exon 20). The three hot-spot mutations, E542K, E545K, and H1047R, have been proven to elevate the lipid kinase activity of PIK3CA...
متن کاملIntraductal papillary mucinous tumors of the pancreas
Intraductal papillary mucinous tumors (IPMTs) are benign and malignant lesions that arise from the epithelial lining of main pancreatic duct and/or branch pancreatic ducts, with excessive mucin production (especially hyperplastic/adenomatous variety). Based on the degree of cytoarchitectural atypia on microscopic examination, IPMTs are classified as benign, borderline, carcinoma in situ and inv...
متن کاملIntraductal papillary mucinous neoplasms of the pancreas.
BACKGROUND/AIMS Intraductal papillary mucinous neoplasms (IPMNs) are neoplasms of the pancreatic duct epithelium characterized by intraductal papillary growth and thick mucin secretion. Quantities of mucin fill the main and/or branches of pancreatic ducts and cause ductal dilatation. This review encompasses IPMNs, including symptoms, diagnosis, management, and prognosis. METHODS A Pubmed data...
متن کاملfocus on the intraductal papillary mucinous neoplasm of the pancreas
intraductal papillary mucinous neoplasms (ipmns) are rare pancreatic tumours, accounting for less of 1-2% of all neoplasms of the gland. main characteristics of ipmns are their favourable prognosis as these pre-malignant or frankly malignant lesions are usually slow-growing tumours and radical surgery is frequently possible. according with the localization of the lesions, three different entiti...
