Analysis of Predictive Markers of Response to Chemotherapy in Microdissected Components of Mixed Neuroendocrine/non-Neuroendocrine Carcinomas Abstract #733

Introduction: Mixed neuroendocrine (NE)/non-NE carcinomas lack pathological or molecular prognostic or predictive markers.
Aim(s): To analyze the pathological features and the expression of genes involved in DNA repair or synthesis in a cohort of mixed NE/non-NE carcinomas from different sites, as compared to patients’ outcome.
Materials and methods: A series of 42 cases (10 from lung, 18 from the gastro-entero-biliary system, 14 from the urogenital tract) was available for clinical and pathological correlates. In 35 cases, residual pathological material was adequate for microdissecting both NE and non-NE components and for quantitative PCR analysis of RRM1, ERCC1, TS and TOPOIIa. Control cases of pure NE and non-NE cancers were analyzed in parallel.

#1204 Clinico-Pathologic and Survival Analysis of 211 GastroEnteroPancreatic G3 Neuroendocrine Carcinomas (GEP-NECs)
Introduction: GEP-NECs show Ki67>20% and/or >20 mitoses x10 HPF. Mixed AdenoNeuroendocrine Carcinomas (MANECs) are mixed exocrine-neuroendocrine neoplasms. NECs are associated with poor prognosis but recent findings have suggested that there is a fraction of patients showing a better than expected survival rate.

#1159 Mixed Adenoneuroendocrine Carcinomas (MANECs) of the Gastrointestinal Tract. ARGENTUM Group
Introduction: Mixed adenoneuroendocrine carcinomas of the gastrointestinal tract are rare neoplasms. In the 2000 WHO classification of endocrine tumors, such neoplasms were defined as mixed exocrine-endocrine tumors when each component represents at least 30% of the lesion. In the most recent WHO classification, such neoplasms are called “mixed adenoneuroendocrine carcinomas” (MANECs). They are a challenge for the diagnostic and treatment.
