SPECT与PSA联合检测诊断前列腺癌的临床意义

目的：探讨放射性核素骨显像与血清前列腺特异抗原联合检测在前列腺癌诊断中的临床意义。方法；采用单光子发射型计算机断层摄影术骨显像及血清ＰＳＡ浓度检测诊断ＰＣａ患者６３例。结果：６３例ＰＣａ患者中，血清ＰＳＡ测定阳性率为９６．８３％，ＳＰＥＣＴ骨显像转移率为５７．１４％。结论：ＳＰＥＣＴ骨显像与血清ＰＳＡ浓度联合检测对于ＰＣａ患者的临床诊断及治疗具有重要的指导意义。

Clinical significance of combined detection of SPECT and PSA in patients with prostate cancer

Purpose:In order to study the clinical significance of combined detection of bone scan and plasma levels of prostatic specific antigen (PSA) in patients with prostatic cancer (PCa).Methods:The retrospective analysis was performed about the results of bone scan by single photon emission computed tomography (SPECT) and plasma levels of PSA by immunological method in 63 PCa cases.Results:The results showed that the positive ratio of PSA was high,but it had only partial referential value in dividing clinical stages,while the bone scan had more important value.Conclusions:These data suggested that the combined detection of the bone scan and the plasma PSA levels would play an important role in the clinical diagnosis and treatment of the patients with PCa.
