Microvessel Density and Prognosis of Gastroenteropancreatic Neuroendocrine Tumors (GEP-NETS) Abstract #180

Introduction: The role of anti-angiogenic agents in GEP-NETS remains to be established. CD105 (Endoglin) identifies the TGF-ß1 receptor which is expressed on endothelial cells involved in tumor angiogenesis.
Aim(s): Preliminary study to determine the association between microvessel density (MVD), determined by CD105 expression, GEP-NET stage and prognosis.
Materials and methods: Thirty-nine patients with GEP-NETs were included in the study. A tissue microarray of tumor representative areas was made. After the immunohistochemical assay for CD105, CD31 and Ki-67, areas of the tumor with the largest number of micro-vessels (“hot spots”) were chosen and the number of microvessels per large magnification field was determined.

#2685 Apatinib Inhibits Tumor Growth and Angiogenesis in PNET Models
Introduction: Angiogenesis has a pivotal role in the growth and metastasis of pancreatic neuroendocrine tumors (PNETs). Apatinib inhibits angiogenesis as a highly selective KDR inhibitor and has been used to treat advanced gastric cancer and malignancies in clinical settings. However, the efficacy of apatinib in PNETs remains unclear.

Introduction: Because of the low incidence, nonspecific symptoms at presentation, lack of awareness, and non-uniform classifications, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) remains a poorly understood disease, and delayed diagnosis is common among patients with GEP-NETs.
