Summary

Permanent seed implant brachytherapy (BT) for prostate cancer slightly impacts sexual function (SF) long-term. Most patients maintain SF, with a 5-year preservation rate of 73.6% after BT.

Area of Science:

  • Urology
  • Oncology
  • Sexual Medicine

Context:

  • Prostate cancer treatment involves various modalities with potential side effects.
  • Permanent seed implant brachytherapy (BT) is a common treatment for localized prostate cancer.
  • Evaluating long-term sexual function (SF) outcomes is crucial for patient quality of life.

Purpose:

  • To assess the long-term effects of permanent seed implant prostate brachytherapy (BT) on sexual function (SF).
  • To compare SF outcomes between patients who received BT with or without neoadjuvant hormone therapy (NHT) and those who underwent radical retropubic prostatectomy (RRP).

Summary:

  • A prospective study evaluated 353 patients undergoing BT and 56 undergoing RRP.
  • Patients receiving BT without NHT (BT NHT-) showed higher post-treatment SF scores compared to those with NHT (BT NHT+).

  • The 5-year SF preservation rate was 73.6% for BT NHT- patients versus 4.3% for RRP patients.

    • Impact:

    • Brachytherapy offers a favorable 5-year sexual function preservation rate compared to radical prostatectomy.
    • Patient age was identified as a significant predictor of post-BT sexual function.
    • Findings support BT as a viable option for maintaining sexual function in prostate cancer patients.
