Of the 22 screened tumor-related genes, only K-ras, p53, and PIK3CA mutations were found in IPMN. K-ras mutations are more prevalent in invasive than premalignant IPMN. The variable coexistence of mutations in the invasive cancer and in the adjacent precursor cells may point to the heterogeneous nature of this tumor.
