摘　　要：目的:探讨不同病理类型肺癌骨转移患者的核素骨显像特点。方法:回顾性分析了246例肺癌骨转移患者的核素骨显像资料。结果:246例手术病理证实的肺癌骨转移病例中,腺癌所占比例最大,为47.6%,其次为鳞癌(36.6%),未分化癌(11.8%),鳞腺混合癌(4.0%);多发核素分布异常者占76.8%,两处核素分布异常者占10.2%,单发异常者占13.0%;转移的部位以胸部诸骨最多见(81.7%),其次为胸椎(51.2%)、骨盆(44.3%)、腰椎(40.7%)。结论:核素骨显像是公认的诊断骨转移的最灵敏的方法,肺癌患者应常规进行骨扫描,这对疾病的分期、治疗方案的选择、预后的评价均有重要的意义。Objective:To investigate the characteristics of radionuclide bone scan on different pathologic types of pul-monary carcinoma patients with osseous metastasis.Methods:The radionuclide bone scan datum of 246pulmonary carcinoma patients were analyzed retrospectively.Results:Among the246patients,adenocarcinoma were most common,the incidence was47.6%,squamous carcinoma was36.6%,undifferentiated carcinoma was11.8%,squamous adenocarcinoma was4.0%.Multi-ple abnormal radionuclide concentration was seen in76.8%patients,10.2%with two foci and13.0%with only one site.Most metastatic foci were seen in bones of the thorax (81.7%),the lesser incidence of involment were thoracic spine (51.2%),pelvis(44.3%),lumbar spine (40.7%).Conclusion:Radionuclide bone scan is the most sensitive method for the diagnosis of osseous metastasis.All the patients with pulmonary carcinoma should be performed radionuclide bone scan,which is significant for stag-ing,selecting therapy methods and the evaluating prognosis of the disease.
