摘要:	RATIONALE AND OBJECTIVES: The aim of this review was to evaluate the diagnostic properties of (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) or PET/computed tomography (CT) and bone scintigraphy in the detection of osseous metastases in patients with lung cancer. MATERIALS AND METHODS: MEDLINE was searched for relevant original articles published between January 1995 and August 2010. Inclusion criteria were as follows: FDG-PET or PET/CT and bone scintigraphy was carried out to detect bone metastases in patients with lung cancer, sufficient data were presented to construct a 2 × 2 contingency table, and histopathologic analysis and/or close clinical and imaging follow-up and/or radiographic confirmation by multiple imaging modalities was used as the reference standard. Two reviewers independently extracted data related to research design, sample size, imaging techniques, technical characteristics, reference standards, methods of imaging interpretation, and totals of true-positives, false-positives, true-negatives, and false-negatives. Stata was used to obtain per patient and per lesion pooled estimates of sensitivity, specificity, and positive and negative likelihood ratios, and areas under summary receiver-operating characteristic curves (AUCs) were calculated. RESULTS: The pooled patient-based sensitivity of FDG-PET or PET/CT was 0.93 (95% confidence interval [CI], 0.88-0.96), specificity was 0.95 (95% CI, 0.91-0.98), and the AUC was 0.94. The pooled sensitivity of bone scans was 0.87 (95% CI, 0.79-0.93), specificity was 0.82 (95% CI, 0.62-0.92), and the AUC was 0.91. The pooled lesion-based sensitivity of FDG-PET or PET/CT was 0.93 (95% CI, 0.84-0.97), specificity was 0.91 (95% CI, 0.80-0.96), and the AUC was 0.97. The pooled sensitivity of bone scans was 0.92 (95% CI, 0.87-0.95), specificity was 0.57 (95% CI, 0.09-0.95), and the AUC was 0.92. CONCLUSIONS: Although FDG-PET or PET/CT has higher sensitivity and specificity than bone scintigraphy, further research with a less biased design is needed to determine the most efficacious imaging modality for the detection of metastatic lung cancer.
