肺癌骨转移的核素骨显像特点及分布规律

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?蛔频牟课灰孕夭恐罟亲疃嗉?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。

Characteristics and the regular distribution of radionuclide bone scan on pulmonary carcinoma patients with osseous metastasis

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.
