Otros tumores neuroendocrinos pancreáticos: glucagonomas, VIPomas, somatostatinomas, no funcionantes y tumores con secreción ectópica

These tumors are usually large and easy to localize. However, highly specific techniques are sometimes required for their localization (endoscopic ultrasonography, octreotide scintigraphy, angiography). Diagnosis is usually made late and metastases are common. Despite the presence of disseminated disease, a subgroup of patients show prolonged survival. Of the multiple treatments available (chemoembolization, radiofrequency, chemotherapy, somatostatin analogs, interferon-alpha), the only curative therapy is complete tumoral resection.
