#2920 Mutation Spectrums Analysis of Colorectal Adenocarcinoma and Neuroendocrine Neoplasm Based on Same Genetic Background to Reveal Tumorigenesis

Introduction: The tumorigenesis of neuroendocrine neoplasm (NEN) are still ambiguous. The therapies of NENs in colon or rectum refer to adenocarcinomas (AC) when tumor metastasis, but the response was unsatisfactory which inspired us to explore the mutation difference.

#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.

#2175 A Retrospective Analysis of 344 Cases with Neuroendocrine Neoplasms

Introduction: Ki-67 is a nuclear protein that is strictly associated with cellular proliferation，acting as a cellular marker for proliferation in clinical practice to determine the degree to which the tumor cells are duplicating. Ki-67 index strongly ties to the prognosis and provides guiding significance to clinical decisions.
