Epirubicin Loaded Polyphosphazene; A New Agent Against Small Intestinal Neuroendocrine Tumors and Medullary Thyroid Carcinomas Abstract #1182

Introduction: Small intestinal neuroendocrine tumors (SI-NETs) represent a group of rare neoplasms, derived mainly from enterochromaffine cells. Medullary thyroid carcinoma (MTC) is a calcitonin-producing neuroendocrine tumor arising from the parafollicular C-cells. SI-NETs as well as MTCs are known for their poor response to standard therapy. Therefore, there is a substantial need to establish new therapeutic options in the clinical treatment of these tumors.
Aim(s): Earlier studies have demonstrated antiproliferative and tumoristatic effects of epirubicin. In this study we investigated the effects of a novel water soluble drug carrier agent, polyphosphazene on small intestinal neuroendocrine tumors and medullary thyroid carcinomas.
Materials and methods: SI-NET and the MTC cell lines were incubated with unloaded and epirubicin loaded polyphosphazenes, and cells were analysed using cell counting and WST-1 cytotoxicity assay. Fibroblasts served as contol cells. In addition, MTC xenografts were treated with unloaded, epirubicin loaded polyphosphazene, and epirubicin intra venous.

Introduction: Lung neuroendocrine tumors (NET) are classified as typical (TC) and atypical carcinoids (AT), according to their mitotic count and the presence of necrosis. However, a role for tumor side (right vs left) and location (central vs peripheric) has not been established so far.

Introduction: Lung neuroendocrine tumors account for 25% of all neuroendocrine tumors. It is a heterogeneous group that meets morphological criteria; immunohistochemical and molecular; defining 4 groups: Typical and atypical carcinoid tumors, neuroendocrine carcinomas with large cell and small cells. Carcinoid syndrome is rare in these tumors and the treatment is based on surgery for localized forms and multimodal treatment for metastatic forms.
