Modified reduce-volume target IMRT

Patients with newly diagnosed, non-metastatic NPC was given modified reduce-volume target IMRT

modified reduce-volume target IMRT

Intervention Type RADIATION

The gross tumor volume of the nasopharynx and neck nodes (GTVnx and GTVnd) were delineated according to the tumor extension. The CTVnx was defined as GTVnx + nasopharynx mucosa + 8mm +corresponding anatomical structure without the delineation of CTV1. The CTVnd was defined as GTVnd plus the elective neck area. The prescribe doses of GTVnx/GTVnd, CTVnx, CTVnd were 66-70Gy,54-56Gy and 50-54Gy in 31-35 fractions, respectively.
