Summary

Interstitial brachytherapy offers precise radiation delivery for head and neck tumors, minimizing side effects. Optimizing low dose rate (LDR) brachytherapy and exploring high dose rate (HDR) and pulsed dose rate (PDR) techniques are crucial for improved outcomes.

Radiation oncology (London, England)·2023

Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Context:

  • Head and neck tumors require high radiation doses for local control.
  • External beam radiation therapy often causes significant side effects in adjacent normal tissues.
  • Interstitial brachytherapy allows for precise dose delivery to the tumor, sparing surrounding structures.

Purpose:

  • To review the established role of low dose rate (LDR) brachytherapy in treating head and neck cancers.
  • To discuss the optimization of LDR brachytherapy techniques for improved therapeutic ratios.
  • To compare preliminary outcomes of high dose rate (HDR) and pulsed dose rate (PDR) brachytherapy with LDR brachytherapy.

Summary:

  • Decades of experience show high doses are needed for head and neck tumor control.

  • Interstitial brachytherapy effectively targets tumors, reducing side effects on salivary glands, mandible, and mastication muscles.
  • LDR brachytherapy is well-established for oral cavity, oropharynx, and nasopharynx cancers, but HDR and PDR offer new challenges and potential benefits.

    • Impact:

    • Optimizing brachytherapy techniques can enhance the therapeutic ratio for head and neck cancer patients.
    • Exploring HDR and PDR brachytherapy may lead to more effective and less toxic treatment options.
    • Minimizing late effects on critical structures improves patient quality of life post-treatment.
