Surgical treatment of pulmonary sarcoma metastases

: During the ten-year period from 1.1.1980 to 31.12.1989, thoracotomy was found performed on 22 patients with malignant sarcoma on account of suspected pulmonary metastases. Fourteen patients were submitted to operation on one occasion, nine patients were submitted to operation twice and one patient was operated upon six times. The median age was 21 years (range 7-68 years). The median interval without illness from the primary treatment was 65 weeks (range 7 weeks to 5.8 years). At the first operation, 13 patients had one metastasis, seven had two metastases and one had five metastases. In one patient, a benign lesion was found. Six patients were submitted to renewed thoracotomy on account of pulmonary metastases from 16 to 75 weeks after the first recurrence. The median survival after the first operation was 1.4 years (range 0.4-5.7 years). Five patients (24%) are still free from recurrences from 0.9 to 5 years after the last operation. It is concluded that patients with malignant sarcoma should be followed-up regularly with radiography of the thorax and should be offered operation in cases of pulmonary metastases.
