Abstract.
Between 1990 and 2000, 56 consecutive patients underwent lung resection for removal of metastatic disease. Mortality, disease-free interval, and overall survival were studied. Only patients with a complete follow-up were included and data were collected conform the protocol of the International Registry of Lung Metastases. The primary tumour in our series was an epithelial tumour in 25 patients (45%), sarcoma in 15 (27%), germ cell tumours in 11 (19%) and melanoma in 5. Operative mortality was 1.4% (1 out of 73 procedures). Germ cell tumours had the best survival (76% at 5 years), and melanoma the worst (0% at 5 years). Multivariate analysis showed that survival for patients who underwent 2 or more metastasectomies was surprisingly good with a 5-year survival rate of 46%. Survival was not related to disease-free interval, multiple lung metastases, or pneumonectomy. It is in accordance with some reports that a short disease-free interval, numerous lung metastases, or recurrence after the first metastasectomy should not preclude patients from operation.
