wIRA superficial hyperthermia
At Dr. Markus Notter (Lindenhofspital Bern - Radioonkologie) presented at the ESHO Annual Meeting, the 22.-25th of May 2019 in Warszawa, an evaluation of 113 patients with preirradiated macroscopic locally recurrent breast cancer (mostly large-sized and inflammatory), who have been treated with wIRA superficial hyperthermia directly following hypofractionated radiotherapy with 5 x 4 Gy, 1x/week (= 20 Gy total reirradiation dose).
Response and local control rates were differentiated by 4 defined tumor sizes.
Corresponding to the characteristics of this disease (high portion of Lymphangiosis carcinomatosa), 51 patients suffered from a new re-recurrence after complete remission (CR) or from a new progression after partial remission (PR).
In 40 of these patients the same protocol was applied another time (hyperthermia + re-re-irradiation), in order to achieve tumor control resp. stabilization.
No acute or chronic (radiotherapy- or hyperthermia-related) adverse effects > grade 2 were observed. Grade 2 adverse effects were limited to teleangiectasia.
By combining wIRA superficial hyperthermia and hypofractionated repeat reirradiation, repeatedly recurrent Lymphangiosis Carcinomatosa can be treated well and sometimes even stabilized for years.
