- Abstract: Objective To explore the predictive value of maximum standardized uptake value(SUVmax)and mean standardized uptake value(SUVmean)parameters in 18F-prostate specific membrane antigen-1007 positron emission tomography/computed tomography(18F-PSMA-1007 PET/CT)for the diagnosis and disease progression of prostate cancer(PCa).Methods Eighty patients with suspected PCa who underwent 18F-PSMA-1007 PET/CT examination in the hospital were selected and divided into the PCa group(49 cases)and the non-PCa group(31 cases)according to the biopsy pathological results.The 18F-PSMA-1007 PET/CT parameters were collected in the two groups of patients at admission,including SUVmax and SUVmean.The prostate specific antigen(PSA)and prostate cancer histological grade(GLEASON)score were also collected in patients of the PCa group at admission and 3 months after admission.The diagnostic efficiency of 18F-PSMA-1007 PET/CT parameters on PCa was analyzed by receiver operating characteristic(ROC)curve.The correlation between 18F-PSMA-1007 PET/CT parameters of patients in the PCa group at admission and PSA,GLEASON score was analyzed by Pearson method.Results The SUVmax and SUVmean in the PCa group were higher than those in the non-PCa group(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)of SUVmax and SUVmean were 0.887 and 0.843 respectively,the sensitivities were 80.65%and 83.87%,and the specificities were 87.76%and 73.47%respectively.The PSA and GLEASON score were lower 3 months after admission than those at admission in the PCa group(P＜0.05).Pearson correlation analysis showed that the SUVmax and SUVmean of patients in the PCa group at admission were positively correlated with PSA and GLEASON score at admission and 3 months after admission(P＜0.05).Conclusion SUVmax and SUVmean parameters of 18F-PSMA-1007 PET/CT have high predictive value for the diagnosis and disease progression of PCa.
