#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH

Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#2878 Surgical Management of Neuroendocrine Tumor-Associated Liver Metastases

Introduction: Liver metastasis is common among patients who suffer from neuroendocrine tumors (NETs). Radical surgery is the standard treatment whenever possible but there is still controversies concerning the treatment strategies such as resection of the primary, role of debulking surgery, liver transplantation (LT) and neoadjuvant or adjuvant therapies.

Introduction: MET has shown antitumorigenic effects on DM cancer pts, which are mediated by decrease of insulin/IGF-1 levels and activation of the AMPK pathway leading to mTOR inactivation.
