Table 2.
Cumulative incidencea of most common cancer entities after 10 years of follow-up
| RPE only [%] | RT only [%] | RT after RPE [%] | p-value* | |
|---|---|---|---|---|
| All second cancer | 10.5 | 15.9 | 13.2 | <.0001 |
| Colon cancer | 1.1 | 1.7 | 2.0 | 0.0017 |
| Rectal cancer | 0.6 | 1.1 | 0.3 | 0.0036 |
| Lung cancer | 1.2 | 2.2 | 1.2 | <.0001 |
| Bladder cancer | 1.1 | 2.7 | 1.5 | <.0001 |
| Non-melanoma skin cancer | 1.2 | 2.1 | 1.6 | <.0001 |
aTo account for competing risks, like death, cumulative incidence analysis was used to calculate time to second malignancy
*p-value was calculated by Gray-Test
