Comparison of histologic type between mucosa and deeper parts (submucosa or deeper) of cancer lesion
| UC-associated (n = 15) |
Sporadic (n = 75) |
P value | ||
|---|---|---|---|---|
| Mucosa area | Deeper area | |||
| Well | Well | 2 | 25 | |
| Well | Moderately | 5 | 18 | |
| Well | Poorly | 2 | 0 | |
| Moderately | Moderately | 1 | 20 | |
| Moderately | Poorly | 3 | 7 | |
| Poorly | Poorly | 2 | 5 | 0.0062* |
| Poorer differentiation in deep parts** | 10 (66.7%) | 25 (33.3%) | 0.033* | |
UC - ulcerative colitis; n - number of cases.
* χ2 test,
** Cases which were shown to be well differentiated at the mucosa and moderately to poorly differentiated at the deep areas, and showed moderately differentiated at mucosa and poorly differentiated at the deep areas.
