Table 1.
Frequency of lesions positive for MUC proteins or αGlcNAc associated with the PanIN‐IDAC sequence of pancreatic tumor progression
| Number of lesions | MUC5AC (%) | MUC6 (%) | αGlcNAc (%) | |
|---|---|---|---|---|
| PanIN‐IDAC | ||||
| Low‐grade PanIN | 17 | 16 (94.1) | 17 (100)a | 17 (100)b |
| High‐grade PanIN/IDS | 12 | 11 (91.7) | 11 (91.7) | 6 (50)b |
| IDAC | 20 | 18 (90.0) | 14 (70.0)a | 8 (40.0)b |
| Total | 49 | 45 (91.8) | 42 (85.7) | 31 (63.3) |
a
Significant difference in MUC6 positivity between low‐grade PanIN and IDAC (P < 0.05).
b
Significant difference in αGlcNAc positivity between low‐grade and high‐grade PanIN/IDS (P < 0.01) and between low‐grade PanIN and IDAC (P < 0.01).
