前列腺癌的诊断与临床分期

回顾性分析６８例经病理学证实的前列腺癌病例，直肠指诊诊断或疑为前列腺癌的病例占８９．７％，经直肠Ｂ超检查诊断符合率为９３．８％（３０／３２），并可显示前列腺包膜、膀胱颈及精囊受累情况，前列腺活检阳性检出率可达９７．３％（３２／３３），ＣＴ检查对精囊受累及盆腔淋巴结转移的诊断有重要价值，核素骨显像是检出骨转移癌最敏感的方法。对前列腺癌的早期诊断和分期方法进行了讨论。

Diagnosis and clinical staging of prostate cancer

cases of prostate cancer,confirmed by pathological study,were evalutated retrospectively.Prostate cancer was diagnosed or suspected on digital rectal examination in 89.7% of the patient.The cancer has been correctly identified on transrectal ultrasonography in 30 of 32 patients(93.8%)and capsular.Seminal vesicle and bladder invasion might be detect ed. Biopsy provided histologic confirmation of prostate cancer in 32 of 33 patients(9.73%).CT scan was of important value in showing seminal vesicle invasion and metastatic involvement of pelvic lymph nodes.Radioisotope bone scans were the most sinsitive means of detecting osseous metastases.Earlier diagnosis of prostate cancer and its clinical staging are discussed.
