Abstract

Background: Prostate cancer (PCa) is a prevalent malignancy in men, with early diagnosis being crucial for treatment and prognosis. This study evaluates the diagnostic efficacy of two-dimensional ultrasound imaging score (2DUS), contrast-enhanced ultrasound score (CEUS), and ultrasound elastography score (UES) in PCa.

Methods: The PCa group consisted of patients diagnosed with primary PCa who underwent radical prostatectomy at the second hospital of Shanxi Medical University between January 2022 and December 2023. The benign lesion group consisted of patients diagnosed with benign prostatic hyperplasia (BPH)through prostate biopsy during the same period. We compared ultrasound scores at PCa and BPH patients using receiver operating characteristic (ROC) curve analysis. The study collected comprehensive patient data and analyzed variations in 2DUS, CEUS, and UES to identify relationships between preoperative ultrasound findings and the pathological states of PCa patients.

Results: PCa patients exhibited significantly higher ultrasound scores (P<0.001). Optimal cut-offs were 2.110 for 2DUS, 3.235 for CEUS, and 2.790 for UES, yielding area under curves (AUC) of 0.789, 0.817, and 0.898. The combined score provided an AUC of 0.933, with 83.33% sensitivity and 90.70% specificity. In the form of that patients with tumor stage III-IV, pathological grade III, poor differentiation, and pelvic lymph node metastasis exhibited significantly higher scores in 2DUS, CEUS, and UES compared to those with tumor stages I-II, pathological grades I-II, moderate and high differentiation without pelvic lymph node metastasis, respectively (P<0.05).

Conclusions: The combined use of 2DUS, CEUS, and UES scores is highly effective for early PCa detection, surpassing individual scores in accuracy, and is beneficial for staging and differentiation.
