Abstract
Objectives. To evaluate the clinical efficacy of high-intensity focused ultrasound ablation (HIFU) for local recurrence of prostate cancer after external beam radiotherapy (EBRT) and radical prostatectomy (RPE).Materials and Methods: During 2007-2013 years 47 patients with local recurrence of prostate cancer after EBRT and RPE undertook HIFU therapy on the system “Ablaterm» (EDAP, France). Relapse arose after an average of 2 years after EBRT and RPE. Median follow-up after HIFU therapy was 38 (12-60) months. The mean age was 68.5 ± 5.8 years. The median PSA level before HIFU – 15.4 (7-48) ng / mL.Results: In 34 patients (72.3%) at six months after treatment the median PSA was 0.4 (0-3.2) ng / mL, in 48 months - 0.9 (0.4-7.5) ng / mL. In 13 patients (27.7%) at 6 months was observed progression of the disease. In general, after a 5-year follow-up 72.3% of the patients had no data for the progression and recurrence.Conclusion: HIFU therapy in patients with local recurrence of prostate cancer after EBRT and RPE is minimally invasive and effective technology.
