Do you have a goal isodose line coverage for skin in the setting of post mastectomy RT with expanders in place?
How about in the setting of treatment after recurrent resected disease if it didn’t involve the skin: would you push for coverage even though planning for reconstruction?
Answer from: Radiation Oncologist at Academic Institution
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.
