HIFU treatment for fibroadenoma - a clinical study at National Scientific Research Centre, Astana, Kazakhstan.

This randomized controlled study evaluated effect of low frequency high intensity focused ultrasound (HIFU) in 80 women with breast fibroadenomas randomly and evenly divided into main and control groups, treated with HIFU and sectoral resection accordingly. In- vitro trial of fibroadenoma samples exposed to different power levels:100 Watt (W), 200 W and 300 W, analysis of results shown that optimal ablation power 200W was enough for coagulation necrosis of tumour, while 300W ablation caused complete destruction of tissues. Results showed that 20% of control group (surgically treated) patients had post-operative complications and 12.
