Neuroendocrine Tumors
Conditions
Brief summary
This study will evaluate the potential immunomodulatory synergy of the association of metronomic cyclophosphamide (CMC) and interferon-alpha (IFN-alpha).
Interventions
50 mg oral tablet, one tablet per day, every day for 6 months; abort if progression or intolerance
3 months of treatment from the 4th cycle metronomic cyclophosphamide : subcutaneous injection, initial dose of 3 MIU three times a week. The dose may be adjusted as tolerated to achieve a T cell counts greater than 500 / mm3
