Results: Results are reported as value ( range ), where value corresponds to median tissue properties, and range is across non hotspot samples. Conventional hyperthermia reached a T90 (temperature in 90% of the GTV) of 39.8°C (38.8-40.2°C) in 28 non-hotspot samples. Robust hyperthermia increased the number of non-hotspot samples to 41, with T90 = 39.5°C (38.6-40.7°C). Adding conventional hyperthermia to conventional radiotherapy increased EQD RT 95% from 45.8 Gy to 50.0 (48.4-50.7) Gy. EQD RT optimization with conventional hyperthermia further raised EQD RT 95% to 56.7 (53.3-57.4) Gy. For robust hyperthermia, EQD RT 95% reached 56.7 (54.6-59.3).
