Recurrence post-fSRT (GTV-R, in red) and volume which received at least 20 Gy (V20Gy, in blue) on the fSRT treatment planning scan in axial, coronal and sagittal cross-sections. (A) “out-field” recurrence with a common volume of 0% between GTV-R and V20Gy; (B) “marginal” recurrence with a common volume of 72% between GTV-R and V20Gy; (C) “in-field” recurrence with a common volume of 89%
