Bevacizumab Plus Octreotide and Metronomic Capecitabine in Patients with Metastatic Well-to-Moderately Differentiated Neuroendocrine Tumors. The XELBEVOCT Multicenter Phase II Study Abstract #415

Introduction: A phase II study was designed to assess the activity and safety of metronomic oral capecitabine, bevacizumab, and octreotide (Xelbevoct) in metastatic well-to-moderately differentiated neuroendocrine neoplasms (WMD-NEN). We also assessed the predictive role for progression free survival (PFS) of hypertension, proteinuria and vascular endothelial growth factor (VEGF) polymorphisms and the predictive role of vitamin D on proteinuria and PFS.
Aim(s): The primary study aim was the response rate, secondary aims were toxicity, PFS and overall survival.
Materials and methods: Forty-five patients, with WMD-NEN from various primary sites, prospectively received Octreotide LAR, 20-30 mg monthly, metronomic capecitabine, 2000 mg/daily and intravenous bevacizumab, 5 mg/kg every two weeks, till nine months. Bevacizumab was prosecuted till progression if indicated.

#431 Everolimus Controlled Resistant Hypoglycemia in Malignant Insulinoma
Introduction: A pancreatic neuroendocrine carcinoma with liver metastases was diagnosed on July 2006 in a 65-year-old man. He was treated with octreotide LAR 30 mg for three years. At liver progression he was enrolled in a multicenter Italian trial titled “XELBEVOCT” with Bevacizumab + Metronomic Capecitabine + Octreotide LAR 30 mg. After seven months, the patient exhibited severe hypoglycemic syndrome with HGT serum levels<30 mg/dl, insulin 150 microUI/ml, and C-peptide at upper normal limits. Endocrinologist prescribed prednisone, diazoxide and recombinant glucagon for hypoglicemic crisis, with little benefit. In March 2010, the patient was given radio-labelled Lu-177-OCTREOTATE treatment. After three cycles, hypoglicemic symptoms were still uncontrolled. CT scan showed stable disease.

#912 Serial 89Zr-bevacizumab PET in Patients with Neuroendocrine Tumors before and on Everolimus Treatment
Introduction: Everolimus increases PFS in patients with advanced NETs. Currently, no biomarkers are available for early selection of patients who will benefit from everolimus. Everolimus can reduce VEGF-A production by tumor cells.

#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.
