#3536 Comparison of drug sensitivity profiles of various NEN spheroids

Introduction: Neuroendocrine neoplasms (NENs) are rare cancers that arise from neuroendocrine cells. NENs are classified as well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Small bowel and pancreatic NETs (SBNET & PNETs) are generally slow-growing but commonly metastasize to the liver and become aggressive cancers. Little is known about the drug sensitivity profile of these 3 NENs due to the lack of cellular and animal models of these malignancies. Recently, we have developed a protocol to culture NEN cells from patient tumors as patient-derived spheroids (PDS) and showed expression of NEN markers. The rarity and slow growing features of these spheroids have been hindering drug screens with many compounds.

#3326 Drug sensitivity profiles of PNET, SBNET and NEC spheroids

Introduction: Neuroendocrine neoplasms (NENs) are rare cancers that arise from neuroendocrine cells. NENs are classified as well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Few mutations have been identified for NETs from the small bowel (SBNETs) and pancreas (PNETs). SBNETs and PNETs are generally slow growing but they commonly metastasize to the liver and can become aggressive cancers. NECs often harbour mutations in key cell cycle genes (TP53 and RB) and are highly proliferative. Little is known about the drug sensitivity profile of SBNET, PNET and NECs due to the lack of cellular and animal models of these malignancies. Recently, we have developed a protocol to culture NET and NEC cells from patient tumors as patient-derived spheroids and showed that they express NEN markers.
