| Outline of Final Research Achievements |
At first, I focused on the Progesterone receptor (PgR) which was suggested the relationship to prognosis of pancreatic neuroendocrine tumor (pNET). I studied the relationship between PgR and ability of insulin production in pNET. PgR expression was associated with insulin expression in pNET. PgR showed high expression in the order of Insulinoma, insulin positive non-functional pNET (ins (+) NF) and insulin negative non-functional pNET (inf (-) NF). Insulinoma and ins (+) NF shared common clinical characteristics, morphology and PgR expression status. On the other hand, ins (-) NF might have a unique pathogensis with little association with PgR expression.
