[Single-center study of the abnormal concentration of bone imaging agent and prostate cancer bone metastasis prediction model].
Objective: To investigate the relationship between total prostate specific antigen (TPSA), free prostate specific antigen/total prostate specific antigen [RAT (F/T)], Gleason score, other factors and the whole-body bone plane imaging which was used to evaluate the bone metastasis of prostate cancer (PCa), and the diagnostic value of the abnormal concentration of bone imaging agent for single lesion. Methods: A retrospective analysis of (99)Tc(m)-methylene diphosphonate ((99)Tc(m)-MDP) whole-body bone imaging data of 93 patients with confirmed PCa in The First Hospital of Shanxi Medical University from Jan 2018 to Jan 2019 was conducted. The bone metastasis was diagnosed by whole-body bone imaging. ⋯ Conclusions: Gleason score, RAT (F/T) and TPSA are important risk factors of PCa bone metastasis. TPSA >92.82 ng/ml is the most supportive diagnosis for PCa bone metastasis. The abnormal concentration of bone imaging agent >3.52 owns the best diagnosis effect for the single lesion of PCa.
