Table 5.
The frequency of individuals with increased lymphocyte sensitivity to DNA damage in various study groups.
| Study groups | Proportion of sensitive subjects (%) with respect to | |||
|---|---|---|---|---|
| Basal DNA damage | H2O2-induced DNA damage | Total | ||
| Initial level | Residual level | |||
| BC patients (n = 40) | 17.5 | 50a | 10 | 62.5b |
| Individuals older than 60 years (n = 15) | 20.0 | 26.67 | 26.67 | 46.67 |
| Individuals with chronic inflammatory diseases (n = 15) | 6.67 | 26.67 | 6.67 | 46.67 |
| Controls (n = 35) | 8.57 | 14.29 | 5.71 | 40.0 |
aSignificant differences were revealed between all the groups by criterion χ 2 (p = 0.009) and between the case group and controls (p = 0.001).
bSignificant differences were observed between BC patients and controls (p = 0.05).
