Meta-analysis Concludes FDG PET is Superior to Conventional Imaging in Lung Cancer
TITLE: Meta-analysis of the efficacy of positron emission tomography with F-18-fluorodeoxyglucose in lung tumors. Basis for discussion of the German Consensus Conference on PET in Oncology 2000
REF: Pneumologie. 2001 Aug;55(8):367-77 http://www.ncbi.nlm.nih.gov/entrez/...8&dopt=Abstract
STUDY TYPE: meta-analysis
PATIENTS: patients with lung lesions and lung cancer
FINDINGS: - PET was superior to CT in evaluating lung lesions (96% sensitivity, 80% specificity, and 91% accuracy for PET).
- In lung cancer patients, PET was superior to CT in determining nodal stage. For PET vs CT, sensitivity was 88% vs 65%, specificity was 92% vs 76%, and accuracy was 91% vs 73%.
- In lung cancer patients, PET was superior to CT in determining metastatic stage. (94% sensitivity, 97% specificity, and 96% accuracy for PET)
CONCLUSION: FDG PET has a high diagnostic accuracy in lung cancer and the workup of lung lesions. PET is superior to all other imaging modalities in this setting. |
