目的 :为了探讨前列腺移行区体积 (TZV)与前列腺总体积 (PGV)两者的体积比率 (PVR)对前列腺癌的诊断价值。方法 :采用经直肠双平面超声检测技术测量 12 4例病人的前列腺TZV及PGV ,并计算其体积比。同时测量病人血清前列腺特异性抗原 (PSA) ,计算其体积密度 (PSAD)和移行区体积蜜度 (PSAT) ,比较PSA、PSAD、PSAT与PVR对前列腺癌的诊断价值。结果 :在BPH和PCA两组间 ,PVR的差异有统计学意义 (P <0 0 1) ,其ROC曲线的AUC =0 83。结论 :PVR对界别前列腺增生症与前列腺癌有较高的诊断价值 ,可作为前列腺癌的初步筛选指标。
OBJECTIVE: To investigate the diagnostic value of volume ratio (PVR) between prostate volume (TZV) and total prostate volume (PGV) in the diagnosis of prostate cancer. Methods: Prostate TZV and PGV in 124 patients were measured by transrectal bi-planar ultrasound technique and their volumes were calculated. The PSA of patients was measured at the same time. The PSAD and PSAT were calculated. The diagnostic value of PSA, PSAD, PSAT and PVR in prostate cancer was compared. Results: There was a significant difference in PVR between BPH and PCA (P <0.01), and the AUC of ROC curve was 0 83. Conclusion: PVR has a high diagnostic value in the diagnosis of BPH and prostate cancer, and can be used as a primary screening index for prostate cancer.
