Post-Op Endometrial RT Contouring

• CTV-T = Upper 3cm of vaginal vault and parametrium.

• PTV-T = CTV + 12mm in all directions except inferiorly and laterally where 7mm is sufficient.

• CTV-N = (as per Taylor guidelines) includes obturator nodes, external iliac lymph nodes, internal iliac lymph nodes. The common iliac nodes may be included for node positive patients (Stage IIIC1). The para-aortic nodes may be included for those with Stage IIIC2 tumours.

• PTV-N = CTV + 7mm margin.

• PTV final = PTV-T + PTV-N
