Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Background:

  • External beam radiotherapy (EBRT) is a key treatment modality for all histological types of thyroid cancer.
  • Standard treatment planning often requires anterior and posterior fields to encompass the entire neck volume down to the suprasternal notch.

Purpose of the Study:

  • To outline the principles and techniques for effective external beam radiotherapy in thyroid cancer management.
  • To describe methods for optimizing radiation delivery while minimizing dose to critical structures like the spinal cord.

Main Methods:

  • Application of antero-oblique wedged pairs for localized treatment.
  • Utilization of anterior and posterior fields for comprehensive neck coverage.
  • Implementation of shielding for mandible and lung apices.

  • Employing three-dimensional CT-planned volumes for phase two planning.
  • Incorporating conformal beam shaping with multileaf collimators.

    • Main Results:

    • A mid-plane dose of 46 Gy in 23 fractions provides acceptable early radiation reactions and avoids late spinal cord damage.
    • CT-based planning and advanced beam arrangements are necessary for precise dose delivery and spinal cord sparing.
    • Phase two planning should be completed before finishing phase one to optimize the overall treatment volume.

    Conclusions:

    • External beam radiotherapy is integral to thyroid cancer treatment across all subtypes.
    • Advanced planning and delivery techniques, including CT and multileaf collimators, are essential for maximizing therapeutic ratio.
    • Careful dose management is critical to prevent spinal cord toxicity and ensure favorable treatment outcomes.
