Background:Lymph node staging of prostate cancer(PCa)is important for planning and monitoring of treatment.18F-prostate specific membrane antigen positron emission tomography/computerized tomography(18F-PSMA PET/CT)has several advantages over 68Ga-PSMA PET/CT,but its diagnostic value requires further investigation.This meta-analysis focused on establishing the diagnostic utility of 18F-PSMA PET/CT for lymph node staging in medium/high-risk PCa.Methods:We searched the EMBASE,PubMed,Cochrane library,and Web of Science databases from inception to October 1,2022.Prostate cancer,18F,lymph node,PSMA,and PET/CT were used as search terms and the language was limited to English.We additionally performed a manual search using the reference lists of key articles.Patients and study characteristics were extracted and the QUADAS-2 tool was employed to evaluate the quality of included studies.Sensitivity,specificity,the positive and negative likelihood ratio(PLR and NLR),diagnostic odds ratio(DOR),area under the curve(AUC),and 95％confidence interval(CI)were used to evaluate the diagnostic value of 18F-PSMA PET/CT.Stata 17 software was employed for calculation and statistical analyses.Results:A total of eight diagnostic tests including 734 individual samples and 6346 lymph nodes were included in this meta-analysis.At the patient level,the results of each consolidated summary were as follows:sensitivity of 0.57(95％CI 0.39-0.73),specificity of 0.95(95％CI 0.92-0.97),PLR of 11.2(95％CI 6.6-19.0),NLR of 0.46(95％CI 0.31-0.68),DOR of 25(95％CI 11-54),and AUC of 0.94(95％CI 0.92-0.96).At the lesion level,the results of each consolidated summary were as follows:sensitivity of 0.40(95％CI 0.21-0.62),specificity of 0.99(95％CI 0.95-1.00),PLR of 40.0(95％CI 9.1-176.3),NLR of 0.61(95％CI 0.42-0.87),DOR of 66(95％CI 14-311),and AUC of 0.86(95％CI 0.83-0.89).Conclusions:18F-PSMA PET/CT showed moderate sensitivity but high specificity in lymph node staging of medium/high-risk PCa.The diagnostic efficacy was almost equivalent to that reported for 68Ga-PSMA PET/CT.
