目的：对肺癌骨转移患者进行观察，旨在探讨肺癌骨转移的特点和规律。方法：肺癌的诊断通过胸片、胸部ＣＴ或ＭＲＩ、痰找癌细胞、纤支镜检查和经皮肺组织活检的明确。骨转移的诊断通过Ｘ线摄片、ＣＴ扫描、ＭＲＩ、ＥＣＴ等检查综合判断。统计学处理采用卡方检验。结果：骨转移单发者占２６．２％，多发者占７３．８％。腺癌平均每例发生骨转移１．９５处，鳞癌平均每例发生骨转移１．６１处。腺癌以胸部及骨盆转移为主，鳞癌胸部及脊柱转移为主。Ｘ线摄片检出率３１．５％，ＣＴ骨扫描为３８．５％，ＭＲＩ为７５％，ＥＣＴ为１００％。死亡者平均存活６．３个月。结论：肺癌骨转移以多发者多见，腺癌骨转移率最高，鳞癌次之。转移部位以胸部最多，其次为骨盆和脊柱。肺癌骨转移检出率最高的检查为ＥＣＴ。骨转移为肺癌预后不良的因素之一
Objective: To observe the patients with bone metastases from lung cancer in order to investigate the characteristics and regularity of bone metastasis from lung cancer. Methods: The diagnosis of lung cancer was confirmed by chest radiographs, chest CT or MRI, orbital search for cancer cells, bronchoscopy, and percutaneous lung biopsy. Diagnosis of bone metastases is judged by X-ray, CT scan, MRI, ECT, etc. Statistical analysis uses chi-square test. Results: 26.2% of patients with bone metastases were single, and 73.8% were multiple. The average incidence of bone metastases was 1.95 in each case of adenocarcinoma, and there were 1.61 bone metastases in each case. Adenocarcinoma is mainly metastasized to the chest and pelvis, and the squamous cell carcinoma is mainly chest and spine. The radiographic detection rate was 31.5%, CT bone scan was 38.5%, MRI was 75%, and ECT was 100%. The average number of survivors was 6.3 months. Conclusion: Bone metastasis of lung cancer is more common in patients with multiple bone metastasis. The rate of bone metastasis in adenocarcinoma is the highest. The site of metastasis was the largest in the chest, followed by the pelvis and spine. The highest detection rate of bone metastases in lung cancer was ECT. Bone metastasis is one of the factors of poor prognosis of lung cancer
