High-Grade Gastroenteropancreatic Neuroendocrine Tumors Compare to Neuroendocrine Carcinomas in 276 Patients

#1754

Introduction: The data compared well differentiated high-grade tumors with poorly differentiated neuroendocrine carcinoma (NEC) are very limited.

Aim(s): It’s important to differentiate them in pathologic and clinical features.

Materials and methods: A total of 276 diagnosed high-grade GEP-NEN were reclassiﬁed.73 cases were reclassiﬁed as well-diﬀerentiated NET,203 cases were poorly-diﬀerentiated NEC. The clinicopathologic features and survival were analyzed.
