During the period between May 1974 and April 1986, 33 patients underwent resection of metastatic lesions of the lung in our department. We analyzed prognostic factors, such as number of metastatic lesions (solitary or multiple), size of solitary tumors and lymph node metastases, and disease free interval. 1) The five year survival rate of patients with solitary metastatic lesions was 55%, significantly better than that of those with multiple lesions (17. 5%; p<0.05). The number of lesions seems to be related to postoperative survival rates, but the size of solitary metastatic tumors is not ralated to the prognosis. 2) Patients with tumor-free intervals of more than 2 years tended to survive longer than those with shorter, but the difference was not statistically significant. 3) In 17 patients lymph node dissections were performed. In 3 of them (17. 6%) malignancy was found in hilar or mediastinal lymph nodes; 1 died of tumor, and 2 had recurrences within 2 years. 4) Eight patients survived for more than 4 years; all had solitary metastatic lesions. Seven of them had no lymph node metastasis, and 1 did not have lymph node dissection.
