Expression of β-tubulin in IDC with and without metastasis in axillary lymph nodes.
| Group | n | - | + | ++ | +++ |
|---|---|---|---|---|---|
| Metastasis | 27 | 0 | 1 | 14 | 12 |
| No metastasis | 23 | 0 | 2 | 17 | 4 |
| Total | 50 | 0 | 3 | 31 | 16 |
A significant difference was observed between the two groups (z = -2.0290, P < 0.05), and the β-tubulin expression was positively correlated to metastasis of axillary lymph nodes (r = 0.4345, P < 0.05).
