Abstract:
Objective To assess the value of CT, PET, PET/CT in diagnosis of peritoneal metastases with Meta analysis. Methods Articles of CT, PET or PET/CT on peritoneal metastases published in English or Chinese from Jan 2000 to May 2008 were collected, and histopathological and (or) surgical findings were taken as golden standards. The sensitivity, specificity, summary receiver operating characteristic (SROC) curves, area under the curve (AUC) and the heterogeneity were calculated with software of SAS 8.0, Meta-DiSc 1.4 and STATA 10.0. Results The results of Meta analysis from 11selected articals showed that PET had the highest pooled specificity [0.96, (0.91-0.98)];PET/CT had highest pooled sensitivity [0.77, (0.67-0.85)]. The AUC and Q~* of PET, PET/CT and CT was (0.92, 0.85), (0.99, 0.96), (0.91, 0.84), respectively. AUC of PET/CT was higher than that of CT (Z=2.33, P<0.05). Conclusion PET/CT is a high accuracy diagnostic tool for detecting peritoneal metastases.
