Context:
Scanty reports have focused on FDG-PET after radiofrequency ablation (RFA), for recurrence of hepatic metastases.
Objective:
To assess FDG-PET diagnostic accuracy on detection of recurrent hepatic lesions.
Methods:
After a comprehensive search of PubMed and EMBASE, we performed a patient-based diagnostic meta-analysis of post-RFA FDG-PET.
Results:
Across nine included articles, independent, random-effects sensitivity and specificity were 0.73(0.50-0.88) and 0.85(0.72-0.93), respectively. A symmetrical SROC curve was produced with no significant heterogeneity. Specificity was optimal for surgical RFA and colorectal origin of metastases.
Conclusion:
Synthesis of published evidence suggests PET/CT as an appropriate tool for optimizing post-ablation follow-up.
