For MUC2, the intestinal-type IPMN had a significantly higher U-index (P>0.001) compared to the other neoplasms, including gastric-type IPMN and PDAC, and the U-index for gastric-type IPMN was significantly lower (P = 0.002) than that for PDAC (Figure 3B). This evidence concerns the gene MUC2 and neoplasm.
