Transrectal ultrasound-guided prostate cryoablation is a promising outpatient treatment for localized prostate cancer, showing an 81% success rate with minimal morbidity. Further research is ongoing to compare its effectiveness against other established treatments.

Area of Science:

  • Urology
  • Oncology
  • Minimally Invasive Surgery

Background:

  • Prostate cryoablation offers an outpatient procedure with minimal blood loss and anesthesia.
  • It is a potentially effective treatment for various stages of localized prostate cancer.

Purpose of the Study:

  • To evaluate the efficacy and safety of transrectal ultrasound-guided percutaneous transperineal prostate cryoablation.
  • To assess its role as a primary or salvage treatment for prostate cancer.

Main Methods:

  • Transrectal ultrasound-guided percutaneous transperineal cryoablation.
  • Treatment of localized prostate cancer in all stages.
  • Follow-up including PSA levels and biopsies.

Main Results:

  • Effective in controlling local prostate cancer in 81% of patients with minimal morbidity.
  • Appears effective for low-volume cancer (PSA < 10 ng/ml, Gleason < 7) with 5+ years follow-up.
  • Salvage cryoablation for recurrent disease after radiation has higher complication rates, especially incontinence.

Conclusions:

  • Prostate cryosurgery is a viable treatment option for primary localized prostate cancer, recurrent cancer after irradiation, and debulking large tumors.
  • Longer follow-up is needed, but current results are promising.
  • Prospective trials comparing cryoablation with external irradiation are anticipated.
