How do you optimize HDR brachytherapy for intracavitary treatment of cervical cancer?
For HDR brachytherapy for cervical cancer do you use the dose optimization algorithm? Is there a standard dwell time distribution that should be the starting point for treatment planning?
Answer from: Radiation Oncologist at Community Practice
We do image based brachytherapy (MRI based). Start with standard weighting for point A dose and there after manually adjust dwell times to get D90> or = 100% and cumultative D2cc for rectum 65 Gy or less, Bladder 80 Gy or less and sigmoid 70 gy or less
With weightedd planning, majority of times ...
