Metastatic insulinoma: current molecular and cytotoxic therapeutic approaches for metastatic well-differentiated...

Pancreatic neuroendocrine tumors (panNETs) are a type of neuroendocrine tumor with 5-year overall survival rates of approximately 50% when metastasis is present at diagnosis. Tumor grade, as defined by Ki-67 proliferation index, influences overall survival, with low-grade tumors portending a better outcome than intermediate- and high-grade tumors. This case report follows the clinical course and management of a patient with an insulin-secreting metastatic panNET who died 10 years after diagnosis after a treatment course with regional therapy and multiple forms of cytotoxic and molecularly targeted agents. This report presents the various treatment options available for patients with insulin-secreting metastatic panNETs.
