Prostate brachytherapy can affect bowel function, but changes are usually minor and improve over time. Supplemental radiation therapy negatively impacts rectal quality of life.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Urology

Background:

  • Prostate brachytherapy is a common treatment for localized prostate cancer.
  • Long-term effects on rectal function are a significant concern for patients.

Purpose of the Study:

  • To evaluate the long-term impact of prostate brachytherapy on rectal function.
  • To assess the influence of supplemental therapies on rectal quality of life.

Main Methods:

  • Prospective study of 161 patients who underwent prostate brachytherapy.
  • Utilized the Rectal Function Assessment Score (R-FAS) for data collection.
  • Median follow-up of 9.0 years, analyzing clinical, treatment, and dosimetric parameters.

Main Results:

Related Experiment Videos

  • The average R-FAS score improved slightly over time (3.59), indicating minimal long-term adverse effects.
  • Only 9.9% of patients reported worsened bowel function post-treatment.
  • Preimplant bowel movements, tobacco use, and diabetes correlated with R-FAS; supplemental external beam radiation was linked to poorer quality of life.

Conclusions:

  • Prostate brachytherapy can cause adverse bowel function changes, but these are typically minimal and resolve over time.
  • Supplemental external beam radiation therapy is associated with a reduced quality of life regarding rectal function.
