Area of Science:

  • Urology
  • Radiation Oncology
  • Medical Physics

Background:

  • Prostate brachytherapy, dating back to 1913, initially used radium capsules with limited success.
  • Early implantation methods for prostate brachytherapy yielded unsatisfactory results.
  • The development of transrectal ultrasound in the 1980s revolutionized prostate brachytherapy techniques.

Purpose of the Study:

  • To summarize the practical development of interstitial permanent prostate brachytherapy (PPB) implantation techniques.
  • To review the historical progression and evolution of PPB methods.
  • To highlight key advancements in PPB over the last century.

Main Methods:

  • Historical review of prostate brachytherapy techniques.
  • Evolution from early radium capsule insertion to modern ultrasound-guided methods.

  • Description of the two-stage Seattle technique and its impact on dose distribution.

    • Main Results:

    • The Seattle technique enabled homogenous radioactive source distribution, achieving biochemical control comparable to surgery and external beam radiotherapy.
    • Advanced computer software and imaging have led to single-stage procedures with on-table dosimetric assessment.
    • Core principles of prostate dose targeting and organ-at-risk avoidance remain critical.

    Conclusions:

    • Permanent prostate brachytherapy has undergone significant technical evolution, driven by imaging and software advancements.
    • Current techniques focus on precise dose delivery to the prostate while minimizing radiation to surrounding organs.
    • The ultimate impact of evolving PPB techniques on long-term biochemical control requires further observation.
