我们自1997年8月～2001年7月对113例直肠指检前列腺有结节和/或血清PSA升高者行直肠B超引导下前列腺穿刺活检和全身骨扫描,就血清PSA对前列腺癌诊断的准确性、敏感性、特异性、阳性预测值(PPV)及与骨扫描阳性率的相关性进行分析,以探讨其临床意义。
We performed a transrectal B-guided prostate biopsy and a whole body bone scan on 113 nodules and / or elevated serum PSA in the rectal exam from August 1997 to July 2001. We examined the relationship between serum PSA and prostate cancer The accuracy, sensitivity, specificity, positive predictive value (PPV) and the positive correlation with bone scan were analyzed to explore its clinical significance.
