Radiotherapy for primary lung cancer: 2025 update

Area of Science:

• Radiation Oncology
• Medical Imaging

Background:

• Lung cancer requires precise radiotherapy planning.
• Standardized guidelines are crucial for effective treatment.
• Previous recommendations needed updating to reflect current practices.

Purpose of the Study:

• To provide updated recommendations for lung cancer radiotherapy.
• To detail the delineation of target volumes and organs at risk.
• To guide radiation oncologists in treatment planning.

Main Methods:

• Review and update of existing French Society for Radiation Oncology guidelines.
• Expert consensus on target volume delineation for lung cancer.
• Detailed methodology for identifying organs at risk in radiotherapy planning.

Main Results:

• Comprehensive updated recommendations for lung cancer radiotherapy indications.
• Specific guidance on delineating planning target volumes (PTVs).
• Precise instructions for contouring organs at risk (OARs) to minimize toxicity.

Conclusions:

• The updated guidelines offer a standardized approach to lung cancer radiotherapy.
• Accurate delineation of PTVs and OARs is essential for optimal treatment outcomes.
• These recommendations will enhance the quality and consistency of lung cancer radiation therapy.
