经直肠超声引导前列腺穿刺活检60例临床分析

目的探寻一种提高可疑前列腺癌患者活检阳性率的方法．方法选择经直肠指诊、血清前列腺特异抗原检查（PSA）及经直肠超声检查疑诊前列腺癌患者共60例，在经直肠超声引导下进行11点系统穿刺活检，获取组织按部位标记后进行病理组织学检查，结果分别与PSA、MRS（磁共振波谱）及SPECT-CT检查结果对照分析．结果成功进行11点系统穿刺活检者49例，获取组织满意．病理诊断为前列腺癌14例，前列腺癌检出率28．57％，疑似前列腺癌2例，不典型增生3例，前列腺增生30例，结论经直肠超声引导前列腺11点系统穿刺活检成功率高，但需进一步积累病例以得到前列腺癌阳性检出率。

Transrectal Ultrasound-guided Prostate Biopsy:an Chnical nalysis of 60 Cases

Objective To find a better method to improve positive biopsy rate of prostate cancer. Methods 60 cases of suspected prostate cancer were selected by digital rectal examination, serum prostate-specific antigen （PSA） and transrectal uhrasonography, then histopathological changes were examined after 11 cores transrectal ultrasound -guided biopsy. Histopathological results were compared with the PSA, MRS （magnetic resonance spectroscopy） and SPECT-CT. Results Only 49 cases are under 11 cores transrectal ultrasound-guided biopsy. The histologic study proved 14 prostate cancer, of which detection rate was 28.57%, 2 suspected prostate cancer, 3 atypical hyperplasia, 30 benign prostatic hyperplasia. Conclusions 11 cores transrectal ultrasound -guided biopsy can improve prostate cancer detection rate with high success, but still need further accumulation of cases in order to obtain.
