前列腺癌的活检信息对患者的风险评估非常重要。目前已经采用阳性活检的数目及范围来预测复发,但活检的阳性部位及其相邻关系能否预测复发尚不清楚。作者比较前列腺活检的阳性部位及其相邻关系与阳性活检的数目及百分比在预测前列腺癌根治术后复发中的作用。收集1992-2002年前 Prostate cancer biopsy information on the risk assessment of patients is very important. At present, the number and range of positive biopsies have been used to predict recurrence, but whether the positive sites of biopsy and their adjacent relationships predict the recurrence is unclear. The authors compared the positive sites of prostate biopsies and their adjacent relationships with the number and percentage of positive biopsies in predicting the recurrence of prostate cancer after radical resection. Collected before 1992-2002
