From 1973 through June 1993, 25 patients underwent pulmonary resection for pulmonary metastases from carcinoma or sarcoma at our institution. There were 11 carcinomas and 14 sarcomas. 24 patients[96% complete] could follow-up and the median follow-up time was 20 months with a range of 4 months to 271 months and total follow-up period was 1105 months-patients. In our patients, actuarial 5-year survival rate was 49%, mean survival time was 66.6$pm$12.6 months and median survival time was 84 months. Patients with sarcoma, more than 24 months of the tumor-free interval, postoperative adjuvant therapy had a better survival than did those with carcinoma, less than 24 months of the tumor-free interval, no postoperative adjuvant therapy. But there were no statistical differences between two groups[P>0.05]. This results recommend more aggressive surgical treatment for pulmonary metastases.
