#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.
