The Value of SUVmax of Gallium-68-PSMA PET/CT in Newly Diagnosed Prostate Cancer

OBJECTIVES: To evaluate the correlation between intensity of prostate specific membrane antigen (PSMA) expression by Gallium-68-PSMA positron emission tomography/computer tomography (Ga-68-PSMA PET/ CT) and D’Amico risk classification newly diagnosed cancer patients. MATERIALS AND METHODS: Retrospective reviews 61 patients, who underwent Ga-68-PSMA PET/CT September 2017 November 2021. Data maximum standard uptake value (SUV max) tissue was collected. The SUV classification, as well Gleason score (GS) grade group (PSA) level, evaluated. For data analysis, Kruskal-Wallis test, Pearson correlation, receiver operating characteristic curve (ROC curve) analysis were carried out. RESULTS: Most patients (50 82%) in high classification. mean SUVmax values primary tumor for all 15.7 ± 10.5. low intermediate-risk (9.5 4.76) significantly lower than those high-risk (17.06 10.93) (p-value 0.013). A positive found GS 0.025), while there a PSA level values. cutoff 8.3 showed sensitivity (84%) specificity (63.6%) detection cancer. CONCLUSION: PSMA tumors is higher with groups staging, but it not correlated level. can be used to screen potentially help an individualized treatment decision.
