IMP3 and pancreatic ductal adenocarcinoma: Similar results have been obtained in studies evaluating high-grade pancreatic ductal adenocarcinomas, renal cell carcinomas, and hepatic carcinomas.(33) Another research group has also reported this association between IMP3 expression and high-grade endometrial neoplasms.(34) We further determined associations between the extent and intensity of IMP3 staining and cases of SC, indicating its potential for distinguishing between different subtypes.
