Evaluation on Diagnostic Value of Ultrasonic Elastography Parameters and Serum Testosterone in the Diagnosis of Prostate Cancer

ABSTRACT

Objective: To explore the clinical diagnostic value of ultrasound elastography (UE) combined with serum testosterone (T) detection in prostate cancer (PCa). Method: A total of 155 patients with suspected PCa admitted to Affiliated Qingdao Third People’s Hospital from January 2020 to January 2022 were included in this study. All the patients underwent UE detection and serum T examination and were divided into positive and negative groups based on histopathological examination results. The detection rates of UE detection, serum T detection and combined detection of the two were compared. T test, nonparametric test and binary logistic regression were used for statistical analysis. The diagnostic efficiencies of single and combined detection were analysed using the receiver operating characteristic (ROC) curve. Result: After the pathological confirmation, 71 cases were classified under the positive group and 84 cases in the negative group. The positive group had significantly higher elastic strain ratio and elastic-image compression index level and a significantly lower serum T level than the negative group (p < 0.05). Elastic strain ratio, elastic image compression index and serum T level were all risk factors for PCa (p < 0.05). ROC analysis showed that the sensitivity of combined detection was significantly higher than that of single detection.Conclusions: Offering a certain clinical application value, the application of combined UE and serum T detection in the clinical diagnosis of PCa can compensate for the shortcomings of single diagnosis, improve diagnostic sensitivity and accuracy and provide a new direction for the clinical diagnosis of PCa (AU)
