External Validation Study Assesses Bone-RADS Malignancy Risk Score

A retrospective review of 423 extremity radiographs with lytic lesions externally validated the Bone-RADS scoring system developed by the American College of Radiology. The study reported that higher Bone-RADS scores were associated with malignant diagnosis (odds ratio 9.7 per 1-unit increase), with 97.1% sensitivity and 67.4% specificity for malignancy; inter-rater agreement for the 4-tier score was moderate (weighted kappa 0.52) but higher for binary benign-versus-malignant classification. The authors concluded the system showed moderate diagnostic performance and could serve as a practical triage framework for lytic bone lesions.

Most relevant for: Clinicians evaluating incidentally found lytic bone lesions on extremity radiographs who are determining malignancy risk and need for further workup.
