TUMOR
Target uniformity and conformity were assessed with planning target volume (PTV) dose coverage (coverage = V95 − gross tumor volume [GTV]/virtual GTV [VGTV]), heterogeneity index (HI), conformity index (CI), and 95% volume of the target area (D95). In detail, V95–GTV represented the volume of GTV included in 95% of the prescribed dose line, and VGTV referred to the volume of GTV. D95–GTV represented the maximum dose of radiation received by 95% of the GTV volume, and Dmax–GTV represented the maximum dose of GTV. The CI was calculated with the following formula: CI = VRX
