Do you have a goal isodose line coverage for skin in the setting of post mastectomy RT with expanders in place?

I don't have a separate goal for skin dose per se in these cases; I primarily look at coverage.

In terms of skin dose for these case, I only worry when there are features concerning for skin recurrence and when using higher energy photons.

Target volume in these patients is based on the location of expander/implant.

If the expander is retropectoral, then the tissue in front of the implant/expander is the target, and you don’t need to chase the coverage of the expander; it is common to see the isodose line break in those areas.

If the ...
