Expression of β-tubulin in DCIS with different nuclear grades.
| Group | n | - | + | ++ | +++ |
|---|---|---|---|---|---|
| Low grade | 26 | 0 | 4 | 13 | 9 |
| High grade | 24 | 0 | 1 | 12 | 11 |
| Total | 50 | 0 | 5 | 25 | 20 |
There was not a statistically significant difference between the two groups (z = -1.122, P > 0.05), and the β-tubulin expression was not significantly correlated to the nuclear grade of DCIS (P > 0.05).
