Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Background:

  • Brachytherapy is a radiotherapy technique involving radioactive isotope implantation.
  • Historically, prostate brachytherapy yielded poor results due to inconsistent dose delivery and patient selection.
  • Advances in technology have renewed interest in brachytherapy for prostate cancer.

Purpose of the Study:

  • To evaluate the efficacy and safety of modern brachytherapy techniques for prostate cancer management.
  • To highlight the impact of technological advancements on brachytherapy outcomes.

Main Methods:

  • Utilizing transperineal template and transrectal ultrasound for precise interstitial implantation.
  • Employing new radioisotopes like palladium-103.
  • Leveraging computed tomography and computerized dosimetry systems for accurate treatment planning and delivery.
