Spectrum of index tumors in different dose ranges (<5% includes unirradiated controls and irradiated groups): (a) SSA was strongly associated with irradiation (p = 0.0001), and LY developed only in the HDV (90–107%). The index tumors from all n = 84 animals were included; (b) LOH was very frequent in sarcomas but only occurred in a minority of non-sarcoma tumors (p = 0.0015); (ce) LOH did not depend on the dose region (p = 0.75), prescribed target dose (p = 1.00) or RT treatment technique (p = 0.27), Fisher’s exact tests (α < 0.05). Abbreviations: SSA, soft sarcoma, LY, lymphoma; BSA, bone sarcoma; LOH, loss of heterozygosity (+/C273X); AN/CBCT/NIRV, combined anesthesia only and cone-beam computed tomography only control groups and non-irradiated volume; LDV, low dose volume; Gy, Gray; VMAT, volumetric-modulated arc therapy; AP/PA, anterior-posterior/posterior-anterior irradiation.
