Insulinoma‐associated protein 1 expression in primary and metastatic neuroendocrine neoplasms of the gastrointestinal and pancreaticobiliary tracts

Abstract

The nuclear reactivity and the high sensitivity and specificity of INSM1 make it a preferred neuroendocrine marker. In conclusion, INSM1 can be used as a single first-line marker for primary and metastatic GEP-NEN.
