目的分析肺癌骨转移诊断方法、分布部位及放射治疗止痛效果。方法总结分析 5 0例肺癌骨转移病例。均采用核素骨显像检查 ,对骨像中呈单发者进一步采用 MRI、CT及 X线平片加以证实。结果转移灶分布于脊柱 (5 3% ) ,胸部骨 (19% ) ,骨盆 (13% )四肢骨(9% )及颅骨 (6 % )。均经放射治疗 ,45例放疗后疼痛得到不同程度缓解。结论肺癌骨转移发生率高 ,对可疑患者应常规行骨显像检查 ,放射治疗止痛效果好 Objective To analyze the diagnostic methods of bone metastasis of lung cancer, distribution sites and radiotherapy and analgesic effect. Methods A total of 50 cases of lung cancer with bone metastases were analyzed. Both using radionuclide bone imaging examination, was single on the bone was further using MRI, CT and X-ray confirmed. Results The metastases were located in the spine (53%), thoracic bone (19%), pelvis (13%) extremities (9%) and skull (6%). After radiation therapy, 45 cases of post-radiotherapy pain were relieved to varying degrees. Conclusions The incidence of bone metastasis in lung cancer is high. Suspicious patients should be routinely examined with bone imaging and the radiotherapy has good analgesic effect
