The role of surgery should be considered separately for pNET-G3 and pNEC-G3. Although SwoM and SwM can be considered for pNET-G3, caution is advised before considering SwM and SwoM for pNEC-G3. Recent studies indicated that PanNEN-G3 includes well-differentiated neuroendocrine tumor with G3 (NET-G3). Introduction: Grade 3 (G3) neuroendocrine neoplasms (NEN), arising from the gastro-entero-pancreatic system (GEP), are classified according to WHO 2010 and defined as having a Ki67 of > 20%. This protocol can be utilized for a variety of procedures and tumor types for clinical care purposes.

He underwent chemotherapy with irinotecan plus cisplatin, followed by carboplatin plus etopside, but his disease did not respond to either regimen. It is scheduled to be annotated soon. Surg Today. We believe that it is important to distinguish between these 2 classifications to avoid using ineffective treatment modalities, and we should do pathologic re-examination when the disease does not respond for first chemotherapy or discontinued chemotherapy to give the appropriate treatment to NEC patients diagnosed by the WHO 2010 classification. 2013 Jul;17(7):1224-32. doi: 10.1007/s11605-013-2221-6.
