Summary

Obese patients can undergo prostate brachytherapy without significant issues. Standard transrectal ultrasound (TRUS) and needles are effective for treating even larger patients, overcoming potential challenges related to obesity.

Area of Science:

  • Urology
  • Oncology
  • Medical Imaging

Background:

  • Obesity presents unique challenges in medical procedures.
  • Brachytherapy is a common treatment for prostate cancer.

Purpose of the Study:

  • To assess potential difficulties of prostate brachytherapy in obese patients.
  • To determine if standard equipment is adequate for obese individuals.

Main Methods:

  • Three obese patients (BMI > 30) underwent prostate brachytherapy.
  • Transrectal ultrasound (TRUS) and a stepper unit were utilized.
  • Accessory table support was needed due to patient weight.

Main Results:

  • TRUS imaging was not compromised by obesity.

  • Periprostate adipose tissue and prostate-rectal distance were comparable to nonobese patients.
  • Standard brachytherapy needles were effective; V100 coverage was 88-95% in two patients.

    • Conclusions:

    • Obesity does not preclude successful prostate brachytherapy.
    • Standard TRUS and brachytherapy equipment are sufficient for obese patients.
