Abstract
Pancreatic neuroendocrine tumors represent 2-10 % of all tumors of the pancreas and approximately 7 % of all neuroendocrine tumors. They are classified as functioning or non-functioning depending on the presence or absence of clinical syndromes associated with hormonal hypersecretion. Insulinomas are the most frequent functioning pancreatic neuroendocrine tumors (45 % of cases), and the most frequent cause of persistent hyperinsulinemic hypoglycemia in adults. Furthermore, 10 % of pancreatic neuroendocrine tumors are associated with multiple endocrine neoplasia type 1 (MEN-1). Insulinomatosis is a distinct clinical entity in which there are multiple insulinomas.
Objectives: Present the cases reported to the date of insulinomatosis and describe the genetic causes, clinical characteristics, treatment and prognosis of insulinomatosis.
Methods: A search about insulinomatosis and the factors that govern beta cells proliferation was conducted in the databases of PubMed, Medline and Google Scholar until July 2020.
Results: 108 cases of patients with insulinomatosis have been reported to date, is recurrent and rarely malignant; multiple protooncogenes and tumor suppressors control locally and systemically the growth of beta cells; however, few have been studied in the tumoral landscape, and MafA mutation in p.Ser64Phe has been involved.
Conclusion: Insulinomatosis is characterized by the synchronous and metachronous occurrence of insulinomas; it has a histological, clinical and genetic phenotype different from other pancreatic neuroendocrine tumors. MEN-1 genetic testing is negative, can be sporadic or hereditary, and MafA could be a driver mutation.
