Development of a 70 MHz unit for hyperthermia treatment of deep-seated breast tumors

What is it about?

we designed a dedicated hyperthermia system for tumors in intact breast consisting of a treatment bed fitted with a 50x40x16cm temperature controlled open water bolus. The patient lies in prone position with the breast immersed in the water positioned in front of a 70 MHz waveguide. Hyperthermia was applied once a week with this 70 MHz applicator for 6 patients treated with thermoradiotherapy for deep lesions of recurrent breast cancer or melanoma. Treatment was well tolerated and the median temperature T50 was 41.1°C.

Why is it important?

This result is impoortant as it is difficult to heat the intact breast properly and without treatment limiting normal tissue hot spots.
