BRAF-V600E Driven Mutations in Grade 3 Neuroendocrine Carcinomas of Colon Origin: Results from Genomic/Epigenomic Profilings and Patient-Derived Mouse Model Abstract #2180

Introduction: NECs of colon origin are orphan and highly aggressive neoplasms with limited molecular knowledge.
Aim(s): To describe the DNA genomic and epigenomic aberrations of colon NECs, generate a patient-derived xenograft (PDX) model to perform translational experiments and translate the results to the clinical setting.
Materials and methods: DNA alterations were defined by VHIOCard (genotyping up to 700 mutations in 70 cancer-related genes). Microsatellite instability (MSI) was analyzed by immunohistochemistry (IHC) and polymerase chain reaction (PCR). Epigenetic changes were studied by DNA methylation analyses using microarray strategy (Illumina®) and compared with colon adenocarcinomas (ADK). We created a BRAFV600E mutated PDX of colon NEC that was treated with cisplatin-etoposide, cetuximab, and the BRAF inhibitor LGX818.

#867 Mixed Adenoneuroendocrine Carcinoma (MANECs): A Rare and Challenging Subgroup of Neuroendocrine Neoplasia
Introduction: Mixed Adenoneuroendocrine Carcinomas (MANECs) are rare entities in which at least 30% of neoplastic cells are neuroendocrine in nature (WHO 2010 classification). They result either from two independent lesions that merge together or are unique lesions with different cell populations intermingled.

#1168 Simultaneous Large Cell Neuroendocrine Carcinoma and Adenocarcinoma of the Stomach: A Case Report and Literature Review
Introduction: Large cell neuroendocrine carcinoma (LCNEC) of the stomach is rare. Gastric NEC occasionally has another component, such as adenocarcinoma, in the same tumor. However, the concurrent occurrence of LCNEC and adenocarcinoma at different sites in the stomach is extremely rare.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.

#2250 Treatment Outcomes of Patients with Mixed Neuroendocrine Non-Neuroendocrine Neoplasms (MiNEN)
Introduction: Mixed neuroendocrine non-neuroendocrine neoplasms (MiNEN) have been newly defined in the WHO 2017 classification. They are rare tumors, commonly treated in analogy to their non-neuroendocrine (nNE) or neuroendocrine (NE) component without systematic data regarding the optimal therapeutic strategy.
