186例肺癌患者核素骨显像骨转移的诊断和分析

Analysis and Diagnosis of Bone Metastases in 186 Patients with Lung Cancer

目的:对不同病理类型肺癌患者行放射性核素骨显像,以观察骨转移的发生率及转移部位。方法:186例确诊的肺癌患者进行99mTc-MDP骨显像,对骨转移的部位、数量与病理类型进行回顾性分析。结果:肺癌患者骨转移发生率为60.22%,肺腺癌较其他类型肺癌更易发生骨转移。骨转移以多发性病灶较为常见,以胸部骨最多见(43.11%),其次为脊柱(26.48%)和骨盆(19.16%)。结论:肺癌患者核素骨显像对肺癌骨转移有重要的临床应用价值。

Objective：To evaluate radionuclide bone imaging in patients wi.th lung cancer for detecting bone metastasis.Methods： 186 patients with diagnosed lung cancer were examined by ^99mTc-MI）P bone imaging, and the bone metastatic sites, quantity and pathological types of those with skeletal metastases were retrospectively analyzed. Results.The incidence of bone metastses was 60. 2 %, the thoracic bones were the most frequent metastatic sites, spinal ,and pelvic bone were the next. The skeletal metastaese of adenocarcinoma was more easily than that of other types of cancer. Conclusion： Radionuclide bone imaging is useful for staging , treating and prognosing of lung cancer.
