Proton-to-photon comparative treatment planning guidelines for the Australian context.

Area of Science:

• Medical Physics
• Radiation Oncology
• Radiotherapy

Background:

• Proton beam therapy (PBT) requires proton-to-photon comparative treatment planning for Australian government funding, both overseas and domestically.
• Fundamental differences exist between PBT and conventional x-ray radiation therapy (XRT) planning and evaluation.
• Inconsistent comparative planning may affect patient eligibility for PBT.

Purpose of the Study:

• To establish guidelines for proton-to-photon comparative treatment planning.
• To ensure national uniformity in the PBT and XRT treatment planning comparison process.
• To support accurate patient eligibility assessment for PBT.

Main Methods:

• Development of a practical reference document.
• Focus on comparative treatment planning between PBT and XRT.
• Guidelines address differences in plan creation and evaluation.

Main Results:

• A practical reference document has been created.
• The guidelines aim to standardize the comparative planning process.
• National uniformity in PBT/XRT plan comparison is the intended outcome.

Conclusions:

• Standardized guidelines are essential for consistent proton-to-photon comparative planning.
• Uniformity in planning facilitates equitable patient access to PBT.
• These guidelines will aid centers in performing comparative treatment planning.
