#1999 Study of Cell Cycle Protein Expression Pattern in Bronchial Carcinoids: A New Potential Target for Medical Therapy?
Introduction: Bronchial Carcinoids (BCs) are rare neuroendocrine neoplasms arising from respiratory epithelium. The only effective treatment option is surgery, but its efficacy is frequently limited by metastatic spread. Everolimus prolongs progression free survival but patients may develop resistance. Previous studies demonstrated that Everolimus reduces viability of NCI-H720 cells (Atypical Carcinoid) but not of NCI-H727 cells (Typical Carcinoid). Everolimus decreases Ciclyn D1 protein levels in both cell lines but NCI-H727 cells survive, indicating a derangement in cell cycle control.

#1090 p27kip1 Is Involved in the Resistance of Human Bronchial Carcinoids to m-TOR Inhibitors
Introduction: Bronchial carcinoids (BC) are still orphan of medical therapy. We previously demonstrated that the typical BC human cell line NCI-H727 is sensitive to Everolimus (E), in terms of cell viability reduction, with a G0 cell-cycle arrest, while the atypical human BC cell line NCI-H720 is not. The mechanisms underlying this phenomenon have not been clarified

#1036 Abrogation of Autophagy by Chloroquine in Neuroendocrine Tumor Cells Treated with mTOR Inhibitors Induces Apoptosis, While Reduction of Cell Proliferation is Due to a Chloroquine, Autophagy Unrelated, Lysosomal Effect
Introduction: The therapy options for patients with advanced NETs are limited. The mTOR inhibitors (mTORi), Torin1 and NVP-BEZ235, are known to suppress cell proliferation in NETs. However, cancer cells may use mTORi-induced autophagy to prolong survival, evading the anti-cancer effect. Chloroquine (CQ) and hydroxychloroquine (HCQ) have been shown to inhibit autophagy.

#344 Cell Cycle Phase Expression Profile Guided Selection of Proliferative Markers for Well-differentiated Small Intestinal Neuroendocrine Neoplasms
Introduction: Grading of neuroendocrine lesions is often determined by Ki-67 (immunostain), despite limited prognostic ability for this cell cycle marker in well-differentiated tumors (WDNETs) and carcinomas.

#160 The role of T-type calcium channels in medullary thyroid carcinoma (MTC): T-type calcium channel blockers inhibit hormone secretion and induce apoptotic cell death in a human MTC cell line
Introduction: Medullary thyroid carcinoma (MTC) accounts for approximately 5-10% of thyroid cancers. In the case of tumors limited to the thyroid gland, the prognosis is generally favorable, whereas 5-year survival averages only 40% in patients with metastatic disease. In these patients, conventional chemotherapy only occasionally leads to a complete response and partial responses are observed in less than 30% of the cases. Therefore, intense efforts are currently directed toward the identification of new druggable targets for the treatment of this devastating disease.

#161 Low Dose Multiple Cycle (LD/MT) Peptide Receptor Radionuclide Therapy: a new concept for the treatment of well-differentiated metastatic neuroendocrine tumors
Introduction: It has been shown experimentally that low dose radiation can effectively kill slow growing cancer cells. Also, external beam radiation therapy applies a fractionated delivery of radiation dose to reduce toxicity with equal or even better therapeutic efficacy.

#1559 MTOR Controls an Epigenetic Program Leading to Autophagy and Cell Growth Control
Introduction: Makroautophagy represents an evolutionary highly conserved process involved in the clearance of proteins and organelles. The induction of this central cellular process is tightly connected with programs regulating cell growth control. While the cytoplasmic machinery that orchestrates autophagy is relatively well understood the key epigenetic events that initiate autophagy-related cell growth programs remain largely unknown.

#2101 The Effect of Temozolomide on Pancreatic Neuroendocrine Tumors in Vitro and Role of MGMT and MMR System in Temozolomide Resistance
Introduction: Temozolomide (TMZ) has been suggested as a treatment option for patients with pancreatic neuroendocrine tumours (PNETs). The tumour response to TMZ has been linked to expression levels of O6-methylguanine-DNA methyltransferase (MGMT) and components of the mismatch repair (MMR) system.

#815 The Effect of Autophagy Inhibitors Alone or in Combination with mTOR Inhibitors in a Neuroendocrine Tumor Cell Model
Introduction: Most patients with neuroendocrine tumors (NETs) require systemic treatment, often with a limited therapeutic effect. RAD001 and Torin1 are mTOR inhibitors (mTORi) known to suppress cell proliferation in NETs. However, cancer cells may use mTORi-induced autophagy to escape the anti-proliferative effect and to prolong cell survival. Chloroquine (CQ) and hydroxychloroquine (HCQ) inhibit autophagy.

#939 Large Cell Neuroendocrine Carcinoma of the Gallbladder: A Case Report and Literature Review
Introduction: Primary large cell neuroendocrine carcinoma (LCNEC) of the gallbladder is rare. The standard treatment for gallbladder NEC with liver metastases has not been established, but combination chemotherapy with etoposide plus cisplatin (EP) is recommended for NEC patients with liver metastasis, regardless of the primary tumor site.
