Surgical treatment of metastatic lung tumor

Since the first pulmonary resection for metastatic cancer of the lung in 1939, the following procedure can now be offered to any patient who meets these criteria: 1. a controlled primary tumor, 2. resectable lung lesion, 3. unavailability of a better treatment and 4. a good surgical candidate. From 1982 to 1992, there were 42 patients who underwent an operation for pulmonary metastasis at the Taichung Veterans General Hospital. Their cumulative 3-year and 5-year survival rates were 35% and 25% respectively. The overall estimated median survival time was 23.1 months. The overall operative mortality was 2.4% (1/42). We analyzed the effect of different types of primary tumors, the disease-free interval, and the number of lesions on patient survival. In our series, we concluded that none of the above had an effect on the therapeutic results.
