Objective: Prostate cancer is the second- leading cause of cancer death among men.
We aimed to evaluate high-intensity focused ultrasound (HIFU), open radical prostatectomy
(ORP), robot-assisted radical prostatectomy (RARP), and external beam radiation
therapy (RT) in the treatment of localized low- and intermediate-risk prostate cancer.

Methods: We searched bibliographic databases for case–control, cohort, and randomized
controlled studies. We used MeSH subject headings and free text terms for prostate
cancer, HIFU, ORP, RARP, RT, failure-free survival (FFS), biochemical disease-free
survival (BDFS), urinary incontinence (UI), and erectile dysfunction (ED).

Results: Fourteen studies were included in the review, for a total of 34 927 participants.
Among the 8 studies of HIFU as the primary treatment of localized low- and intermediate-
risk prostate cancer, 4 studies reported 5-year FFS rates ranging from 67.8% to
97.8%, 3 studies reported 5-year BDFS ranging from 58% to 85.4%, 5 studies reported
1-year UI rates ranging from 0% to 6%, and 4 studies reported 1-year ED rates ranging
from 11.4% to 38.7%. Furthermore, our search revealed a 5-year FFS benefit favoring
ORP compared to RT, a 1-year UI rate favoring ORP compared to RARP, and a 1-year ED
rate favoring ORP compared to RARP.

Conclusion: Our systematic review and meta-analysis revealed lack of studies with
active comparators comparing HIFU to standard of care (ORP, RARP, or RT) in primary
treatment of localized low- and intermediate-risk prostate cancer. Open radical prostatectomy
has favorable efficacy outcomes compared to RT, while RARP has beneficial
functional outcomes compared to ORP, respectively.
