PAX6 is a useful marker for pancreatic origin of neuroendocrine neoplasms: A tissue microarray study evaluating more than 19,000 tumors from 150 different tumor types
19 Nov 2024
Abstract excerpt
PAX6 immunohistochemistry (IHC) was proposed as a tool to identify a pancreatic origin of neuroendocrine neoplasms (NENs). To evaluate the diagnostic utility of PAX6 IHC, a tissue microarray containing 19,214 samples from 150 tumor types was analyzed. Data on progesterone receptor (PR) and glutamate decarboxylase 2 (GAD2) expression were available from previous studies. PAX6 staining occurred in 2.6% of 17,224...
