[Radiotherapy promises: focus on lung cancer]

Area of Science:

• Radiation oncology
• Medical imaging in cancer therapy
• Advanced radiotherapy techniques

Context:

• Radiotherapy practice has evolved significantly due to advancements in medical imaging and technology.
• Computed tomography (CT), MRI, and PET imaging are crucial for precise tumor targeting and delineation.
• New techniques like image-guided radiotherapy (IGRT) and stereotactic radiotherapy offer improved treatment efficacy and reduced toxicity.

Purpose:

• To summarize recent advancements in radiotherapy, focusing on improved precision, personalization, and safety.
• To highlight the role of medical imaging and novel irradiation techniques in modern cancer treatment.
• To discuss the impact of radiotherapy accidents on quality control and safety protocols.

Summary:

• Systematic use of CT, fused with MRI or PET, enhances target identification and delineation.
• Image-guided radiotherapy (IGRT) enables personalized treatment by accounting for anatomical variations, leading to adaptive radiotherapy (ART).
• ART optimizes treatment planning during the course to minimize toxicity and maximize tumor control, with lung cancer as an illustrative example.
• Radiotherapy accidents have prompted enhanced quality control measures, including identity verification and in vivo dosimetry.
• The integration of systemic therapies with radiation requires further study to balance efficacy and toxicity.

Impact:

• Personalized cancer treatment through IGRT and ART improves tumor control and reduces patient toxicity.
• Enhanced quality control and safety protocols, driven by past incidents, ensure safer radiotherapy delivery.
• Ongoing research into multimodal approaches, combining radiation with systemic therapies, promises more effective cancer management.
