|High intensity focused ultrasound treatment for relapsing extra-abdominal desmoid tumours|
MR-HIFU was technically successful in all patients without severe side effects. In one patient with desmoid in the popliteal fossa, the deeper parts of the tumor could not be targeted because of proximity to nerve and vessel structures. Follow-up periods range from 2 to 60 months. Initial targeted median tumor volume was 23 ml (range 3 – 70 ml), volumes decreased significantly in all patients (Table 1). Two patients required more than one treatment session due to insufficient sonication during the first session (patient nr. 4 needed two session, patient nr. 5 needed three session). After successful MR-HIFU treatment there was no relapse or progression of disease. No patient needed general anesthesia and all patients were treated as outpatients. Skin injury was correlated with distance to skin (average 0,7 cm [0,5-0,9 cm]) and/or proximity to bone (i.e. ribs). Both patients accepted the risk beforehand. Skin burns completely healed after a few weeks.
