Title: Epidemiology of Pancreatic Endocrine Tumor in Japan
Abstract: We conducted a nationwide survey to estimate the incidence of neuroendocrine gastrointestinal tumors newly diagnosed in Japan from 2002 through 2004. Five hundred and fourteen pancreatic endocrine tumors (PETs) were collected and analyzed. Nonfunctioning tumors (NF-PETs) constituted 47.7% of PETs. Next in frequency were insulinoma (31.7%) and gastrinoma (8.6%). Malignancy was frequent in NF-PETs (46.1%) and gastrinomas (45.5%), but only 7.4% of insulinomas were malignant. The incidence of multiple endocrine neoplasia type-1 associated with PETs was 7.4%. At present, the epidemiological investigation performed in 2005 in Japan is being analyzed, and the results of this survey will be disclosed in the very near future.
