Abstract
During the last 20 years, 32 operations for metastatic lesions in the lungs and chest have been performed on 29 patients. The longest survival time in our series is 111/2 years (the primary tumour was cancer of the breast). Two other patients had a survival time exceeding 5 years (the primary tumours were cancer of the uterus and osteogenic sarcoma of the humerus), and one patient will soon reach the 5-year-survival line (the primary tumour was sarcoma of the uterus). Operation for solitary metastases to the lungs and chest constitutes in selected cases a small operative risk and the results are compared with the operative results for bronchial cancer. The prognosis of carcinoma is more favourable than of sarcoma and best when the primary tumour is situated in the colon, kidneys or uterus. A long interval between the discovery of primary tumour and the occurrence of metastasis gives a better prognosis.
