MUC4 and familial pancreatic carcinoma: Table 3a shows that MUC4 expression was not predictive of the type of the lesion (pancreatic cancers versus cysts) (p=0.106). After controlling for age, sex, and smoking status, MUC4 remained unpredictable of the type of lesion (pancreatic cancer and pancreatic cyst) (p=0.733).
