wIRA-heating of piglet skin and subcutis in vivo: proof of accordance with ESHO criteria for superficial hyperthermia


Thermography-controlled superficial hyperthermia using water-filtered infrared A (wIRA) is a new method to efficiently treat irresectable locally recurrent superficial tumors in combination with radiotherapy, especially in pre-irradiated areas. Recently, the evaluation of 201 patients with locally recurrent breast cancer has been published in cancers.

The quality assurance guidelines of the European Society for Hyperthermic Oncology (ESHO) specify the II. Technical requirements for heating devices using phantoms. In this piglet study, superficial heating using wIRA has been examined under in vivo conditions. Heating rates and specific absorption rates were in full accordance with the ESHO standards.
