目的:探讨超声结合前列腺特异抗原(PSA)测定诊断前列腺癌(PCA)的价值。方法:对超声拟诊前列腺癌的患者,测定其PSA绝对值、相对值(包括PSA密度、PSA速度)。结果:超声疑似前列腺癌的患者,筛选40例PSA绝对值及相对值均高于正常的患者,行前列腺切除术,术后病理证实,正确率80%。结论:超声在诊断前列腺癌方面有重要地位;但前列腺癌的诊断需结合PSA测定等其他检查手段。
Objective: To investigate the diagnostic value of ultrasound combined with prostate specific antigen (PSA) in the diagnosis of prostate cancer (PCA). Methods: The absolute PSA value and relative value (including PSA density and PSA speed) of patients with suspected prostate cancer were measured. Results: 40 cases of patients with suspected prostate cancer underwent prostate biopsy and 40 patients whose absolute value and relative value of PSA were higher than normal. The correct pathology confirmed that the correct rate was 80%. Conclusion: Ultrasound plays an important role in the diagnosis of prostate cancer. However, the diagnosis of prostate cancer needs to be combined with other tests such as PSA test.
