直肠指检、血清前列腺特异抗原和经直肠前列腺超声诊断临床局限性前列腺癌

采用直肠指检(DRE)、血清前列腺特异抗原(PSA)和经直肠前列腺超声(TRUS)检查诊断早期前列腺癌,将110例经根治术的标本经病理证实为包膜内的癌肿患者归纳入本研究。当三种方法分别进行时,结果有很大不同,阳性率不是很高,但若将三种方法结合运用时,所有患者均有阳性改变。提示:DRE仍为诊断早期前列腺癌的有效方法;34.5％的包膜内癌肿患者的PSA小于10ng/ml,TRUS为一项有意义的辅助检查。

Diagnosis of clinically organ-confined prostatic cancer by DRE,PSA and TRUS

Presented in this study was to evaluate the value of three commonly used methods for diagnosis of clinically organ-confined prostatic cancer (PCa) in symptomatic patients: digital rectal examination (DRE),serum prostatic specific antigen(PSA)and transrectal ultrasonography(TRUS). One hundred and ten patients with organ-confined PCa were histologically confirmed after radical prostatectomy. All patients underwent the three examinations before the operation. Preoperative results were retrospectively studied. An abnormal change could be found in all patients by the combination of the three methods. DRE remains useful in detecting clinically organ-confined PCa. 34.5% of patients with organ-confined PCa in this group have a serum PSA less than 10 ng/ml. TRUS is a valuable adjuvant examination to DRE and PSA.
