New-mode reduced CTVp
Conventional CTVp
Patients with newly diagnosed, non-metastatic NPC was given New-mode reduce-volume target IMRT. The CTVp was defined as a subclinical disease consisting of 8 mm margin surrounding GTVnx (not including all nasopharyngeal mucosa)
Patients with newly diagnosed, non-metastatic NPC was given conventional reduce-volume target IMRT. The CTVp was defined as GTVnx + entire nasopharynx mucosa + 8 mm + corresponding anatomical structures.
