Abstract
BACKGROUND:
Serum concentrations of soluble mesothelin-related peptides (SMRP) have been reported to be higher in patients with malignant mesothelioma than in healthy subjects and in patients with non-malignant mesothelioma diseases. The aim of the present meta-analysis was to establish the overall diagnostic accuracy of the measurement of SMRPs for diagnosing malignant mesothelioma.
METHODS:
After a systematic review of English language studies, sensitivity, specificity, and other measures of accuracy of serum SMRPs in the diagnosis of malignant mesothelioma were pooled using random-effects models. Summary receiver operating characteristic curves were used to summarize overall test performance.
RESULTS:
Eleven publications from 12 studies met our inclusion criteria. The summary estimates for SMRPs in the diagnosis of malignant mesothelioma in the studies included were sensitivity 0.64 (95% confidence interval 0.61-0.68), specificity 0.89 (0.88-0.90), positive likelihood ratio 7.10 (4.44-11.35), negative likelihood ratio 0.39 (0.31-0.48), and diagnostic odds ratio 19.35 (10.95-34.17).
CONCLUSIONS:
Serum SMRP determination plays a role in the diagnosis of malignant mesothelioma. The results of SMRP assays should be interpreted in parallel with clinical findings and the results of conventional tests.
