• Resumen

  • Objective: This study aimed to explore the clinical and differential diagnostic value of real-time ultrasound elastography combined with transabdominal prostate calcification in prostate cancer (PCa).

    Methods: This study retrospectively analysed the clinical pathological data of 97 patients with PCa and 105 patients with benign prostatic hyperplasia (BPH) diagnosed by postoperative pathology in our hospital from May 2020 to May 2021; Comparatively analysed the clinical data of the two groups, including the elastic strain ratio, elastic image compression index, types of prostate calcification and calcification diameter; And used logistic regression analysis to screen out the independent risk factors for identifying PCa and BPH.

    Results: No significant difference in age, body weight, body mass index, location of calcification and calcification diameter was observed between the two groups (p > 0.05), and overt differences in elastic strain ratio, elastic image compression index, types of calcification, and testosterone were found between the PCa group and BPH group (p < 0.05). Logistic regression analysis showed that the elastic strain ratio, elastic image compression index and types of calcification were independent risk factors for identifying PCa (p < 0.05). The area under curve value of combined diagnosis under receiver operating characteristic curve was as high as 0.756 (95% CI: 0.691–0.813), with a sensitivity of 67.60% and a specificity of 76.30%.

    Conclusions: A certain correlation is observed amongst elastic strain ratio, elastic image compression index, types of prostate calcification and the occurrence and development of PCa. The application of real-time ultrasound elastography combined with the detection of transabdominal prostate calcification in clinical diagnosis can improve the detection rate of PCa, which has an important clinical application value.
