#3044 Efficacy of Alkylating Agent Re-challenge after Therapeutic Pause in Metastatic Pancreatic Neuroendocrine Tumors (PanNET)
Introduction: Temozolomide (TMZ) and dacarbazine (DTIC) are alkylating agents (ALK) with antitumor efficacy in metastatic PanNET. Rechallenging ALK following prior efficacy is commonly performed but has not been evaluated.

#2734 Therapy-Related Myeloid Neoplasms in Patients with Neuroendocrine Neoplasms after Peptide Receptor Radionuclide Therapy: A Systematic Review
Introduction: Therapy-related myeloid neoplasm (t-MN) has been reported as a potential long-term and frequently lethal adverse event after PRRT in NET. However, the incidence, time of diagnosis, and nature of t-MN is unclear.

#55 Metronomic combination therapy including temozolamide, bevacizumab and somatostatin analogue for the treatment of malignant gastroenteropancreatic neuroendocrine tumors
Introduction: Malignant gastroenteropancreatic neuroendocrine tumors (GEPNETS), mainly carcinoids, are not considered to be particularly chemotherapy-sensitive to conventional chemotherapeutic schemes. Long-standing evidence suggests these tumors to be highly vascularised and responsive to antiangiogenic strategies. Newest reports demonstrate benefit by the use of temozolamide, an oral alkylating agent similar to intravenous dacarbazine. The DNA repair enzyme O6-alkylguanine–DNA alkyltransferase (AGAT) confers cancer cell resistance to O6-alkylating agents such as temozolamide through its ability to remove methyl/alkyl groups from the O6-position of guanine, thus correcting drug-induced DNA damage.

#748 O6-Methylguanine-DNA Methyltransferase Deficiency in Neuroendocrine Tumors and Correlation with Response to Alkylating Agents (Temozolomide, Streptozotocin, Dacarbazine)
Introduction: Low O6-methylguanine-DNA methyltransferase (MGMT) expression is predictive of response to alkylants in some tumor types.

#1067 Gemox or Alkylating Agents in Neuroendocrine Tumors? The Help of O6-Methylguanine-DNA Methyltransferase (MGMT) Status?
Introduction: Alkylating agents are the backbone chemotherapy in neuroendocrine tumors (NET). However, gemcitabine associated to oxaliplatine (gemox) has showed interesting activity in a small study.

#1337 O6-Methylguanine DNA Methyltransferase (MGMT) Deficiency and Response to Aranoza-Based Therapy in Patients with Neuroendocrine Tumors
Introduction: Aranoza (3-α-L-arabinopyranosyl-1-methyl-nitrosourea) – nitrosourea derivative, as STZ. O6-methylguanine DNA methyltransferase (MGMT) is an enzyme implicated in chemotherapy resistance to alkylating agents and its low levels are associated with sensitivity to them.

#1471 Chemotherapy for Stage IV Sporadic Pancreatic Neuroendocrine Tumors (pNET): Are Partial Responses to Post-first Line Chemotherapy Predictable by Response/Type of First Line Chemotherapy?
Introduction: Three types of chemotherapy are recommended for stage IV pancreatic neuroendocrine tumors (pNETs): streptozocin (STZ)-, dacarbazine (DCZ)- and oxaliplatin (OX)-based. Whether cross resistance exists is unknown.

#2742 Anti-Tumor Effects of Semaphorin 4D Blockade Unravel a Novel Pro-Invasive Mechanism of Vascular Targeting Agents
Introduction: One of the main consequences of inhibition of neovessel growth produced by angiogenesis inhibitors is increased intratumor hypoxia. Growing evidence indicates that tumor cells escape from this hypoxic environment to better nourished locations, presenting hypoxia as a positive stimulus for invasion. Particularly, anti-VEGF/R therapies produce hypoxia-induced invasion and metastasis in a spontaneous mouse model of pancreatic neuroendocrine cancer, RIP1-Tag2.
