Summary

Modern prostate brachytherapy, using Iodine-125 seeds, is increasingly used in Japan due to its precision and patient benefits. High-dose-rate brachytherapy is also employed, with outcomes comparable to traditional treatments.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Context:

  • Prostate brachytherapy has evolved significantly in Japan since its introduction in 2003.
  • The technique offers precise radiation delivery, minimizing damage to surrounding healthy tissues.

Purpose:

  • To provide a comprehensive overview of contemporary prostate brachytherapy practices in Japan.
  • To highlight the advantages and increasing adoption of brachytherapy for prostate cancer treatment.

Summary:

  • Permanent transperineal prostate brachytherapy with Iodine-125 (I-125) is increasingly utilized.
  • High-dose-rate (HDR) brachytherapy with Iridium-192 (Ir-192) also has a history in Japan.
  • Brachytherapy offers precise dose adaptation, improved quality of life, and comparable long-term outcomes to surgery and external beam radiation therapy.

Impact:

  • Brachytherapy is recommended for organ-confined and low-risk prostate cancers.
  • It may require supplemental external beam radiation therapy for cases with a high risk of extraprostatic extension.
  • Further development of sophisticated brachytherapy techniques in Japan is encouraged.
