HIFU vs Radical Prostatectomy For the Treatment of Prostate Cancer

  • HIFI is the largest prospective comparative multi-center clinical study ever conducted evaluating oncologic and functional outcomes of localized prostate cancer treatments
  • 3,328 prospective patients enrolled, including 1,967 consecutive HIFU patients and 1,361 Radical Prostatectomy (RP) patients across 46 centers.
  • Study met both primary endpoint (non-inferior salvage treatment-free survival at 30 months) and secondary endpoint (favorable functional outcomes at 12 months)

Prostate Cancer Control

Primary Endpoint: Salvage Treatment-free survival at 30 months.

Salvage Treatment is defined by the use of any salvage treatments such as Radical Prostatectomy (RP), Radiation Therapy (RT) and/or Androgen Deprivation Therapy (ADT) due to cancer progression.

Superior Functional Outcomes

Favorable Urinary Continence and Erectile Function Preservation at 12 months (Secondary Endpoint)

Urinary Continence

Pad-Free Continence at 12 months

URINARY CONTINENCE

The International Continence Society (ICS) index, a measure of strict urinary incontinence (no leakage vs. at least one leakage per day), was significantly less deteriorated for HIFU (29%) vs, RP(44%) (RR=0.66 [95%CI, 0.59-0.74], p<0.001) for all ages combined.

Erectile Function

Decrease from baseline at 12 months

ERECTILE FUNCTION

The International Index of Erectile Function (IIEF), which measures erectile function, was significantly less reduced at 12 months after HIFU compared to RP with a difference in medians of -3.0 (-3.9; -2.1) between both groups.

“This nationwide trial is the first to prospectively comparing HIFU and surgery for the treatment of localized prostate cancer. The results demonstrate that medium-term salvage treatment-free outcomes are comparable with a better safety profile favoring HIFU.” – HIFI Study Authors

PATIENT INCLUSION CRITERIA

The patient inclusion criteria was defined following the 2014 recommendations from the National Prostate Cancer Committee:

– Localized, low- to intermediate risk PCa
– Clinical Stage T1-2 NxM0
– Prostate Specific Antigen (PSA) dosage < 15 ng/mL

– Gleason score ≤ 3 + 4 (Grade Group 1 or 2)
– Not eligible for active surveillance (AS)
– Maximum of 4 invaded sextants out of 6 on biopsies performed following multiparametric MRI (mpMRI)
– HIFU was restricted to patients over 69 years old with at least a 5-year life expectancy

“The primary endpoint, 30-month STFS adjusted on the variable used to propensity score construction, was in the HIFU group 90% versus RP group 86%. Non-inferiority analysis showed that HIFU had a lower risk of ST compared to RP (HR=0.71[ 95%CI, 0.52-0.97], p=0.008). This result remains when focusing on GG2 (HR=0.66[ 95%CI, 0.50-165 0.86], p=0.001).” – HIFI Study Authors

HIFI Study Conclusion

  • The HIFI Study Successfully met the primary endpoint of non-inferior Salvage Treatment-free
  • Survival (STFS) after HIFU compared to Radical Prostatectomy (RP) at 30 months:
    Patients treated with HIFU had a significantly higher adjusted STFS at
    30 months of 90% versus 86% STFS in patients who underwent RP.
  • Functional outcomes demonstrated better results with respect to urinary continence and erectile function in patients receiving HIFU therapy versus patients receiving RP.
