Comparison of K‐ras point mutation distributions in intraductal papillary‐mucinous tumors and ductal adenocarcinoma of the pancreas

Abstract excerpt

Intraductal papillary-mucinous tumors (IPMT) consist of cells with varying histologic degrees of severity and exhibit multiple tumor loci; however, whether or not these lesions exhibit the same genetic changes has not been clarified. To investigate this point, we analyzed K-ras mutations in multiple IPMT lesions from each patient enrolled in our study and compared our findings to those for patients with ductal...
