Design outcomes

Primary

Measure	Time frame
The dosimetric indices of all 40 patients will be statistically analyzed using a patient-averaged dose-volume histogram, to evaluate the advantages and disadvantages in PTV coverage and OARs sparing for the prone and supine position.	—

Secondary

Measure	Time frame
Subgroup analyses of the dosimetric indices will be performed according to gender and radiotherapy course.	—
