• Secure CTV-HR coverage – macroscopic tumour burden • Uninvolved uterus is NOT the most critical target – microscopic disease • Clinical practise: • ~15-20mm is common for CTV-T LR to PTV margin • Be aware of rectal filling at time of treatment planning! E.g. threshold of 40mm diameter of filling.
