Frequency of lesions positive for MUC proteins or αGlcNAc associated with the IPMN‐IPMNAIC sequence of pancreatic tumor progression
| Number of lesions | MUC5AC (%) | MUC6 (%) | αGlcNAc (%) | |
|---|---|---|---|---|
| IPMN‐IPMNAIC | ||||
| Low‐grade IPMN | 19 | 19 (100) | 18 (94.7)a | 18 (94.7)b |
| High‐grade IPMN | 10 | 10 (100) | 7 (70.0) | 5 (50.0)b |
| IPMNAIC | 8 | 8 (100) | 3 (37.5)a | 0 (0)b |
| Total | 37 | 37 (100) | 28 (75.7) | 23 (62.2) |
a
Significant difference in MUC6 positivity between low‐grade IPMN and IPMNAIC (P < 0.01).
b
Significant difference in αGlcNAc positivity between low‐grade IPMN and high‐grade IPMN (P < 0.01), between high‐grade IPMN and IPMNAIC (P < 0.05), and between low‐grade IPMN and IPMNAIC (P < 0.01).
