对前列腺普通穿刺活检法与系统性6针穿刺活检法的准确性及早期诊断率进行比较。对56例怀疑前列腺癌患者行前列腺穿刺活检。结果35例采用6针系统穿刺活检法,19例确诊为前列腺癌,其中B期11例(36％),C～D期3例(1％);21例采用普通活检法,11例确诊为前列腺癌,B期2例(6.7％),C～D期8例(26.7％〕。经会阴肛指引导下前列腺6针穿刺活检可以提高早期前列腺癌的诊断率。
The accuracy and early diagnosis rate of general 6-needle aspiration biopsy and prostatic biopsy were compared. Prostate biopsies were performed on 56 patients with suspected prostate cancer. Results 35 cases were diagnosed as prostate cancer by using 6-needle system and 19 cases were diagnosed as prostate cancer. Among them, 11 cases (36%) were in stage B and 3 cases (1%) in stage C ~ D; 21 cases were diagnosed as normal biopsy and 11 cases were diagnosed as Prostate cancer was diagnosed in 2 cases (6.7%) in stage B, and 8 cases (26.7%) in stage C ~ D. The 6-needle prostatic biopsy guided by perineal anus could improve the diagnosis rate of early stage prostate cancer.
