Prostate cancer (PCa) is the most prevalent non cutaneous cancer in occidental countries. In Brazil incidence was about sixty thousand new cases in 2016 and occupied second place as all cancer mortality, just behind lung cancer. Literature shows than younger patients tend to have more aggressive tumors rising cancer specific mortality scores. Main risk factors are age, life style (sedentary, high meat and fat intake) and family history (gene inheritance).
Besides vast advances in precocious tumors detection, challenges remain in the definition of the biological status of the tumor, which is highly variable and full of prognostic implications. PCa heterogeneity is demonstrated by the uncertain natural history, varying from indolent lesion to aggressive metastatic and fast progression cancer resistant to conventional therapies. In an actual treatment scenario, prognostic identification is the cornerstone of daily practice treatment considering the natural history variability cited before and the discrepancy of long term slow growth (studies estimate eight to sixteen years of tumor growth to achieve metastatic disease) to high grade aggressive cancer.
Considering all this background and taking in account the indolent evolution of low risk PCa new therapies emerge with promising outcomes. High-Intensity Focused Ultrasound (HIFU) have to be highlighted due to easy operation, good oncologic results and low complication profile. The method is based on real-time imaging guided high intensity ultrasound (US) causing overheat and cavitation in the focused tissue. Applied since 90's, mainly in German and French groups, initially programmed to treat hole gland preserving only urinary sphincter and bladder neck, showed recently some data on 1700 patients, 5 years biochemical recurrence free survival of 80% and best results including morbidity profile in low risk, low prostate volume and in the group with previous trans urethral prostate resection (TURP). This results are very similar to other radical treatment options with median follow up of 8 years, cancer specific survival 98% and metastasis free survival of 95% If local recurrence was identified another HIFU ablation or even radical treatment achieved good results in local control with acceptable morbidity profile.
Focal treatment is a new entity in PCa therapy. One randomized trial compared focal treatment to active surveillance in 513 mans with PCa diagnosis. With a 24 month follow-up progression-free ratios (28% x 58%) and positive control prostate biopsy ratios (14% x 49%) were fairly superior in treatment group. This exiting novel data turns urological oncology paths to the new era of minimally harmful therapy with targeted focused procedure. At our knowledge there is no high evidence clinical trial comparing HIFU to active surveillance.
The objective of this study is to evaluate prospectively the initial experience with 50 patients submitted to HIFU therapy for low risk prostate cancer in Brazilian single center considering the following aspects:
One year of treatment prostate biopsy positiveness; Biochemical recurrence free survival using Phoenix and Stuttgart criteria in one year; Sexual function using IIEF-5 questionnaire and the usage of 5-phosphodiesterase inhibitors (5-PDI); Urinary symptoms using EPIC and IPSS questionnaires and free urinary flow; Quality of life based on SF-36 questionnaire evaluation; Post procedure morbidity using Clavien-Dindo classification.
