Neuroendocrine tumors are rare but recent data showed a relevant increase in its incidence. The Mammalian Target of Rapamycin (mTOR), one of most important area of research, has demonstrated be a therapeutic target in these tumors. The metformin has demonstrate in preclinical studies having an antineoplastic action by inhibiting the mTOR pathway, and may be an alternative treatment for this disease.
Eligible patients for this study should have metastatic gastroenteropancreatic neuroendocrine tumors well differentiated (grade 1 or grade 2) and will be treated with metformin 850 mg every 12 hours, and each cycle will consist of 30 days. After 180 days of treatment the efficacy of metformin under the control of disease progression will be evaluated. As a secondary outcome the investigator will check the patient adherence to the treatment, the control of patient symptoms with functioning neuroendocrine tumor, and disease free survival. Also will be performed an analysis of immunohistochemical expression of mTOR pathway proteins of these patients.

850mg of metformin every 12 hours.
- Disease free survival [ Time Frame: After 180 days of treatment. ]
- Number of Participants with Adverse Events Related to Metformin Measured of Safety and Tolerability [ Time Frame: Assessments will be performed until 180 days after treatment initiation ]Clinical evaluation of metformin related toxicity will be assessed at each medical visit (once a month).
- Clinical benefit [ Time Frame: Assessments will be performed until 180 days after treatment initiation. ]Clinical benefit will be measured using CTCAE version 4.03 for analysis of adverse events presented by patients.
- Biochemical response [ Time Frame: Assessment will be performed at day 90 and 180 of treatment. ]Biochemical response defined by tumor markers.
- Evaluation of patient`s glycemic profile [ Time Frame: Assessment will be performed at day 90 and day 180 of treatment. ]
