Treatment plan analysis for the PTVs and related BED10.
| iHD-SBRT (n = 41) | CRT (n = 41) | p-Value Wilcoxon Test | |
|---|---|---|---|
| PTV1 | |||
| Median volume, cm3 (IQR) | 99.6 (77.0–121.9) | 422.7 (277.2–691.3) | <0.001 |
| Mean dose (Gy), median (IQR) | 37.7 (35.7–39.2) | 50.2 (47.8–52.9) | <0.001 |
| Related BED10 (Gy), median (IQR) | 66.1 (61.2–69.9) | 60.3 (57.0–63.4) | <0.001 |
| SIB-PTV (PTV3) | |||
| Median volume, cm3 (IQR) | 71.4 (61.5–94.5) | / | / |
| Mean dose (Gy), median (IQR) | 40.7 (39.4–42.0) | / | / |
| Related BED10 (Gy), median (IQR) | 73.8 (70.5–77.3) | / | / |
| Dmax | |||
| Mean Dmax (Gy), median (IQR) | 52.0 (49.1–52.5) | 56.4 (51.7–61.6) | <0.001 |
| Related BED10 (Gy), median (IQR) | 106.1 (97.3–107.6) | 68.4 (61.3–7.4.6) | <0.001 |
PTV = planning target volume; IQR = interquartile range; Gy = gray; BED10 = biologically effective dose (α/β = 10); Dmax = maximum dose, SIB = simultaneous integrated boost.
