Local Control Rate (LCR) 12 months after start of radiotherapy for all lesions and lung lesions
| All (N = 100) | Lung (N = 75) | ||||
|---|---|---|---|---|---|
| LCR – 12 months | All | 93.8% (N = 83) | 93.5% (N = 61) | ||
| BED ≤ 100 Gy | 90.7% (N = 55) | p = 0.43 | 89.7% (N = 39) | p = 0.51 | |
| BED > 100 Gy | 100% (N = 28) | 100% (N = 22) | |||
| GTV ≤ 14 cm3 | 98.1% (N = 58) | p = 0.06 | 97,9% (N = 51) | p = 0.02 | |
| GTV > 14 cm3 | 84.9% (N = 25) | 74.1% (N = 10) | |||
| Cox regression | BED | p = 0.36 (0.994) | p = 0.21 (0.986) | ||
| GTV | p = 0.72 (1.013) | p = 0.16 (0.986) | |||
p-values indicate significance determined by log-rank test. Cox Regression is shown with p-values and hazard ratio in brackets. (BED: Biologically Effective Dose, GTV: Gross Tumor Volume).
