Table 2 Evaluation of the calculated ITVWEPL by: volume comparison with the ITVG5 (mean, minimum and maximum are shown); directional expansion relative to the CTV (HD95%); COM variation relative to the CTV. The reported values as Q25% and Q75% correspond respectively to the first and third quartiles of the data
