Biologically equivalent HDR fractionation schedules used for brachytherapy boost calculated by the linear-quadratic model.
| Low boost dose group (n = 21) 20 Gy LDR-equivalent fractionation schemes (calculated for late effects; α/β ratio = 4 Gy) |
High boost dose group (n = 79) 20 Gy LDR-equivalent fractionation schemes (calculated for early effects; α/β ratio = 10 Gy) |
|---|---|
| 1 × 8 Gy (n = 2) | 1 × 10.35 Gy (n = 8) |
| 2 × 5.2 Gy (not used) | 2 × 6.4 Gy (n = 1) |
| 3 × 4 Gy (n = 19) | 3 × 4.75 Gy (n = 70) |
