Rectal dose and target dose have range.
Preferred rectal dose for D2cc < 65 Gy but can accept up to D2cc < 75 Gy, provided you understand expected risk of complications with increased dose.
Preference would be to do hybrid applicator with 3D imaging to optimize HRCTV and OAR.

While IGBT and consideration of hybrid approach, if possible, are ideal options ...
