Image-Guided Radiotherapy and Chemotherapy in Gynaecological Cancer

Take home message: nodal CTV

• Margins add to considerable irradiation of normal tissue

• PTV margin for elective target volume: • 7-10mm margin without daily image guidance • 5mm margin with daily image guidance and bony fusion

• Potential in pelvic elective radiotherapy to reduce irradiated volume by 40% with IMRT and daily IGRT (2500cc → 1500cc)
