Metastatic lung tumor from renal cell carcinoma were studied in 29 cases. Eighteen patients were treated surgically, 11 were treated non-surgically. The overall 5-year survival rate with the patients of pulmonary resection was 53.5%, and that with those of conservative therapy was 0%, and this difference is statistically significant (p < 0.05). There was no significant difference in any characteristics such as sex, age, stage, grade, disease free interval, metastatic pattern and combination with or without interferon therapy. There was no significant difference in surgically treated patients with pulmonary metastasis in terms of any factors such as age, sex, stage, grade, disease free interval, pulmonary metastasis pattern, metastatic number, surgical procedure, combination with or without interferon therapy statistically. Analysis for the surgically treated patients with pulmonary metastasis from renal cell carcinoma shows no significant difference in prognosis with any characteristics. This result shows efficacy of surgery even if for the patients with synchronous bilateral multiple pulmonary metastasis from renal cell carcinoma.
