Abstract:Objective: To quantitatively analyze the parameters of ultrasound elastography (UE) of prostate cancer (PCa) and explore its application value in clinical staging of PCa. Methods: 84 cases of patients with PCa in our hospital from December 2016 to May 2018 were given transrectal real time elastography (TRTE) and given the quantitative analysis of elasticity scoring, elastic area ratio (AR), elastic strain rate ratio (SR) and elastography strain index (SI). And the relationship between each parameter and pathological grade and clinical staging of PCa was studied. Results: Among 168 patients with PCa, 61 cases were highly differentiated (36.31%), and 73 cases were moderately differentiated (43.45%) and 34 cases were poorly differentiated (20.24%), and the clinical staging showed 12 cases (7.14%) in T1 stage, 46 cases (27.38 %) in T2 stage, 83 cases (49.40%) in T3 stage and 27 cases (16.07%) in T4 stage, and there were statistically significant differences in the TRTE hardness scores in patients with different pathological grades and clinical stages (P<0.05). With the increase of PCa differentiation degree, the SR and ASI were significantly increased (P<0.05), and the difference was statistically significant in the groups (P<0.05). The AR, SR and ASI at T1~T4 of PCa patients were significantly increased (P<0.05), and the SR and ASI at T2 stage were higher than those at T1 stage, and there were statistically significant differences in the AR, SR and ASI at T2~T4 (P<0.05). After Spearman correlation coefficient analysis, TRTE elasticity score, SR and ASI were significantly positively correlated with PCa pathological grade (P<0.05), and elasticity score, AR, SR and ASI were positively correlated with PCa clinical staging (P<0.05). Conclusion: Quantitative analysis results of UE image elasticity score, AR, SR and AI have important guiding significance for PCa clinical staging and treatment.
