恶性肿瘤转移至肺部者一般预后恶劣。但如原发瘤已行根治术,局部无复发征,肺转移灶较局限,而其他器官又未发现另有转移者,则仍宜考虑肺切除术。作者等曾于1959年报导9例肺转移瘤行肺切除术治疗,随诊观察生存一年以上者7例,生存两年以上者3例。根据上述经验,我们认为应用肺切除术 Malignant tumors generally have poor prognosis when they are transferred to the lungs. However, if the primary tumor has undergone radical resection, local recurrence-free signs, and lung metastases are more limited, and other organs have not found any other metastases, it is still advisable to consider pneumonectomy. The authors reported in 1959 that 9 patients with pulmonary metastases underwent lung resection. Follow-up observations were observed in 7 patients who had survived for more than one year, and 3 patients who had survived for more than two years. Based on the above experience, we believe that the use of lung resection
