RESULTS : Our data showed that : tuberous sclerosis 2 ( TSC2 ) and phosphatase and tensin homolog ( PTEN ) were downregulated in most of the primary tumors , and their low expression was significantly associated with shorter disease - free and overall survival ; somatostatin receptor 2 ( SSTR2 ) was absent or very low in insulinomas compared with nonfunctioning tumors ; and expression of fibroblast growth factor 13 ( FGF13 ) gene was significantly associated with the occurrence of liver metastasis and shorter disease - free survival .
