MUC1 and intestinal type adenocarcinoma: The histological classification[4] indicated that CK20 had high sensitivity (100%) for intestinal-type carcinoma and that MUC1 had high sensitivity (94%) for pancreatobiliary-type carcinoma (Table 2, Figure 1), and both correlations were significant (p < 0.001 and p < 0.001, respectively).
