肺是全身血流的必经之路,肺的毛细血管是很好的滤血器,因此肺部是全身各种肿瘤最常见的转移部位之一。据尸检证实约29～40%的恶性肿瘤有肺转移病变。肺部具有良好的天然对比,肺转移瘤的早期诊断主要是 X 线检查,且对治疗和预后又有很大关系,所以对每一恶性肿瘤患者都应寻找肺部有无转移。此外,少数病人首先发现肺部转移,其胸部 X 线表现又可为寻找原发肿瘤提供一定的线索。本文收集我院1951～1984年资料较完整的150例肺转移瘤,对其 X 线表
The lungs are the only way for systemic blood flow. The capillaries of the lungs are good blood filters, so the lungs are one of the most common metastatic sites of various tumors in the body. According to autopsy, approximately 29 to 40% of malignant tumors have lung metastatic lesions. The lungs have a good natural contrast. The early diagnosis of lung metastases is mainly X-ray examination, and there is a great relationship between treatment and prognosis. Therefore, for each malignant tumor patient should look for whether the lung metastasis. In addition, a small number of patients first discovered lung metastases, and their chest X-ray findings could provide clues for finding primary tumors. This article collected 150 cases of pulmonary metastases in our hospital from 1951 to 1984, and its X-ray table
