Table 7 Radiobiological (LQ) modelling: calculated comparator regimen and SABR equivalent parameters

From: Stereotactic ablative radiotherapy (SABR) as primary, adjuvant, consolidation and re-treatment option in pancreatic cancer: scope for dose escalation and lessons for toxicity

  Total Dose (D) Fraction Dose (d) Fractions (n) Duration (days) BED (Gy10) BED (Gy3)
Comparator regimen (100% dose to PTV) 50.4 Gy 1.8 Gy 28 37 40.5 Gy 80.6 Gy
SABR equivalent 23.55 Gy 7.85 Gy 3 3 40.5 Gy 77.0 Gy
  Number of patients treated with total dose ≥ 23.55 Gy = 39/42 (92.9%)
Comparator regimen (min 95% dose to PTV) 47.88 Gy 1.71 Gy 28 37 37.5 Gy 75.27 Gy
SABR equivalent 22.35 Gy 7.45 Gy 3 3 37.5 Gy 77.85 Gy
  Number of patients treated with minimum PTV dose ≥ 22.35 Gy = 21/42 (50%)
