Gross tumor volume (GTV) in LRF patients was significantly larger than in controlled LRC individuals (p < 0.01). Isodose comparison showed PTV1 in controlled patients tendentially better covered, with less volumes getting doses < 95 %, compared with failed patients. * : the 2 patients with xerostomia grade 3 and the 3 patients with ulcers related to tumor persistence were excluded from this analysis. | |||
