Skin surface temperature was limited to ≤43 °C. Tissue temperatures were measured invasively at 1-min intervals before, during and after wIRA exposure using five fiber-optical probes at depths of 1-20 mm.Significant differences between body regions occurred during the heating-up phase at depths of 5-15 mm. Thermal steady states were reached at depths ≤5 mm after exposures of 5-6 min, and ≤20 mm after 20 min. On average, the minimum requirements of ESHO were exceeded in both regions by the following factors: ≈3 for the heating rate, ≈2 for the specific absorption rate and ≈1.4 for the temperature rise. Tissue depths with T90 ≥ 40 °C and T50 > 41 °C were ≤10 mm, and ≤20 mm for Tmax ≤ 43 °C. The temperature decay time after termination of irradiation was 1-5 min. Corresponding temperatures were ≤42.2 °C for CEM43 and ≤41.8 °C for CEM43T90, i.e., they are inadequate for direct thermal cell killing.Thermography-controlled wIRA-HT complies with the ESHO criteria for superficial HT as a radiosensitizer and avoids the risk of thermal skin toxicity.}, keywords = {ESHO guidelines (Other) / Water-filtered infrared-A (wIRA) irradiation (Other) / mild hyperthermia (Other) / skin thermography (Other) / superficial hyperthermia (Other) / tissue thermometry (Other)}, cin = {FR01}, ddc = {610}, cid = {I:(DE-He78)FR01-20160331}, pnm = {899 - ohne Topic (POF4-899)}, pid = {G:(DE-HGF)POF4-899}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:37592457}, doi = {10.1080/02656736.2023.2244208}, url = {https://inrepo02.dkfz.de/record/278616}, }
