Key result
18FDG PET/CT detects distant metastasis with ~86% accuracy in pediatric sarcoma, outperforming PET and conventional imaging.
Why the study?
The diagnostic accuracy of 18FDG PET/CT in staging pediatric sarcomas, particularly for nodal and distant metastases, required clarification.
Does 18FDG PET/CT improve diagnostic accuracy for staging nodal and distant metastases in pediatric patients with sarcomas compared to PET alone or conventional imaging?
Comparison
18FDG PET/CT vs 18FDG PET alone vs conventional imaging
Design
Retrospective observational study with consensus image review
Follow-up
Follow-up examinations for lesion progression confirmation

May support 18FDG PET/CT staging in pediatric sarcomas; leaves open prospective validation against conventional imaging.

Does 18FDG PET/CT improve diagnostic accuracy for staging nodal and distant metastases in pediatric patients with sarcomas compared to PET alone or conventional imaging?
Absolute Event Rate: 86% vs 66%
p-value: p=0.002 vs PET, 0.008 vs CI
18FDG PET/CT provides significantly higher diagnostic accuracy for detecting distant metastases in pediatric sarcomas compared to PET alone or conventional imaging.
Tateishi et al. (2007) conducted an observational in Pediatric sarcomas (n=50). 18FDG PET/CT vs. 18FDG PET alone and conventional imaging was evaluated on Diagnostic accuracy of distant metastasis (p=0.002 vs PET, 0.008 vs CI). 18FDG PET/CT correctly detected distant metastasis in 86% of pediatric sarcoma patients, demonstrating significantly higher diagnostic accuracy than PET alone (66%, P=0.002) or conventional imaging.
