[Which dose constraints on which critical organs in paediatric radiation therapy?]

Area of Science:

• Pediatric Oncology
• Radiation Oncology

Context:

• Childhood cancers account for 1% of all cancers in developing nations.
• Overall survival rates for pediatric cancers approach 75% at 5 years.

Purpose:

• To discuss radiation doses to critical organs and frequent radio-induced late-effects in pediatric cancer patients.
• To highlight the persistent challenges of long-term toxicities despite treatment optimization.

Summary:

• Radiation therapy advancements have reduced doses and improved treatment planning, aiming to decrease long-term toxicities.
• Despite these advances, radiation toxicity remains common in pediatric cases, manifesting as neurological, sensory, endocrine, or growth impairments.

Impact:

• This paper will inform strategies for managing and mitigating late-effects of radiation in childhood cancer survivors.
• Understanding critical organ doses is crucial for minimizing long-term adverse outcomes in pediatric oncology.
