^99mTC-MDP全身骨显像165例前列腺癌骨转移的分析

目的通过全身骨核素显像，探讨前列腺癌转移病灶在全身骨的分布情况。方法通过单光子发射电子计算机断层显像，对165例确诊为前列腺癌的患者行全身骨显像，对病灶的部位分布作出分析。结果发生骨转移的患者为85％。在有骨转移患者中，发生脊椎转移占75％，肋骨和／或胸骨转移占64％，骨盆转移65％，股骨转移28．6％，肱骨转移11％。结论前列腺癌易发生骨转移，特点是以中轴骨为主，多灶转移。

The distributing rule of skeleton metastasis in patients with prostate cancer.

Objective To evaluate the distributing rule of skeleton metastasis in patients with prostate cancer using SPECT(Single Photon Emission Computed Tomography).Methods SPECT were performed on 165 patients with prostate cancer.Results 85 percent of patients with prostate cancer had skeleton metastasis.In the patients with skeleton metastasis,the spine,rib and/or sternum,pelvis,thighbone and shoulder bone involvements were 75 percent,64 percent,65 percent,28.6 percent and 11 percent,respectively.Conclusion The patients with prostate cancer had easily had skeleton metastasis.The characteristic of skeleton metastasis was dominant in axial bone and had many focus.
