[Imaging of tumor predisposition syndromes]

Area of Science:

• Oncology
• Radiology
• Genetics

Background:

• Tumor predisposition syndromes (TPS) represent a diverse group of inherited cancers, potentially underdiagnosed in pediatric populations.
• Approximately 10% of childhood malignancies in Germany arise from inherited predispositions.
• This review emphasizes imaging strategies for Li-Fraumeni syndrome, neurofibromatoses, tuberous sclerosis, overgrowth syndromes, and neuroendocrine syndromes.

Purpose of the Study:

• To review imaging modalities for diagnosing and monitoring pediatric tumor predisposition syndromes.
• To highlight the importance of early tumor detection in inherited cancer syndromes.
• To discuss specific syndromes including Li-Fraumeni, neurofibromatoses, tuberous sclerosis, overgrowth, and neuroendocrine syndromes.

Main Methods:

• Regular screening at defined intervals is crucial for each TPS.
• Ultrasonography and magnetic resonance imaging (MRI), particularly whole-body MRI, are key imaging techniques.
• Innovative MRI techniques enhance image quality and patient comfort, reducing scan times for pediatric patients.

Main Results:

• Early tumor detection through consistent screening is essential.
• Advanced MRI techniques allow for faster, more comfortable examinations, even in young children without anesthesia.
• Optimized MRI protocols improve image quality and reduce acquisition times.

Conclusions:

• Routine screening with ultrasound and MRI significantly lowers morbidity and mortality in patients with TPS.
• Timely diagnosis and management through appropriate imaging are vital for improving outcomes in pediatric genetic cancer syndromes.
• The review underscores the critical role of imaging in managing inherited cancer predispositions.
