I’m planning my first GYN case
A learning roadmap: the concepts and resources to understand before planning cervix, post-operative endometrial or vulvar radiotherapy and GYN brachytherapy. It is not instruction on how to treat any specific patient.
- See the GYN treatment pages
Cervix, post-operative pelvis, vulva and brachytherapy.
- Understand bladder filling and the ITV
Why GYN cases are scanned with a full and an empty bladder.
- Understand image fusion for GYN targets
MRI and PET/CT, and why the match focuses on the tumor rather than bone.
- Understand the vaginal cuff ITV
How the post-operative target accounts for cuff movement.
- Understand bowel space contouring
Bowel space versus individual loops, and why the limits differ.
- Review contouring resources
Organ contouring guides for the pelvis.
- Understand EQD2
The basis for adding external beam and brachytherapy doses.
- Understand cervix brachytherapy volumes
HR-CTV, IR-CTV and point A.
- Understand D2cc and the planning aims
How brachytherapy organ doses are judged.
- Review the constraint tables
Every GYN external beam limit, with the source behind each value.
- Understand basic plan evaluation
Putting coverage, hotspots and organ doses together.
