Grading and Prognostication of Neuroendocrine Tumors of the Pancreas…
Grading of pancreatic neuroendocrine tumors (pNETs) is currently based on mitotic rate and Ki67 proliferation index. Phosphohistone-H3 (PHH3) is an effective marker for mitosis that has been proposed to use in grading various NETs.
