April 12, 2017 — Theraclion announced results of a study evaluating the long-term assessment of breast fibroadenoma (benign tumor) volume reduction following treatment with the company’s Echopulse, a non-invasive treatment employing ultrasound-guided high-intensity focused ultrasound. The study, entitled “Long-term efficacy of ultrasound-guided high-intensity focused ultrasound (US-guided HIFU) treatment of breast fibroadenoma,” was published online in the March 2017 issue of the Journal of Therapeutic Ultrasound and is available online.
The study assessed a total of 20 female patients with 26 breast fibroadenomas (BFAs) before and for up to 24 months following echotherapy treatment with Echopulse. Nineteen BFAs received a single treatment and seven BFAs a second treatment six to nine months after the initial session. BFA volume was measured by ultrasound. Patient satisfaction on cosmetic results and symptom relief were surveyed and safety and tolerability was recorded. The study demonstrated consistent echotherapy results confirmed at 24 months:
- Mean BFA volume was significantly reduced by 77.32 percent after a single procedure and by 90.47 percent after two procedures at 24 months follow up;
- No cases of re-growth of treated lesions were observed during the 24 months follow-up;
- Treatment was very well-tolerated regardless of whether one or two echotherapy sessions were performed. Side effects were mild and transient and resolved completely; no serious side effects were observed;
- Of the 20 patients who completed a satisfaction survey, all 20 (100 percent) were completely or highly satisfied with the cosmetic results and 19 of 20 (95 percent) were completely or highly satisfied concerning symptom disappearance; and
- Authors concluded that “US-guided HIFU represents a promising non-invasive method with sustainable FA volume reduction and patient’s tolerability. Although one treatment is highly efficient, the volume reduction can be increased with second treatment.”
Roussanka Kovatcheva, M.D., professor of endocrinology at the University Hospital of Endocrinology of Sofia, Bulgaria, and Principal Investigator said, “Our results show the long-term efficacy and safety of US-guided HIFU generated by Theraclion’s Echopulse in patients with breast fibroadenomas. US-guided HIFU is definitely an effective non-invasive alternative to surgery enabling more than 90 percent volume reduction without re-growth or serious adverse events.”
