If using hyperthermia in breast reirradiation, what type of protocol do you follow?

There are a few options we consider when using hyperthermia

1. Hyperthermia and RT are given twice weekly, ex. 32-40 Gy/8-10 fx with hyperthermia
2. Daily RT with twice weekly hyperthermia- 40/15, or 50/25 for example, with twice weekly hyperthermia. Sometimes consider concurrent capecitabine as well.
