What margin do you use when treating the prostate bed/fossa?

Do you use the same or more generous PTV expansions as definitive prostate cases?

Answer from: Radiation Oncologist at Community Practice

We use similar PTV margin of 5 mm. The only difference is in the definition, surgical bed CTV also includes ITV at the level of SV.
