title: [Surgical treatment of pulmonary metastases (author's transl)].
abstract: From April 1954 till February 1976, pulmonary resections for metastases of primary extrapulmonary malignancies have been done on 35 patients, 21 men and 14 women with average age of 49 years 7 months. In about half of the cases the lung opacities were discovered occasionally. Three patients have undergone a second thoracotomy for a recurrent metastasis. Of the 48 resected metastatic lesions, 31 were located in the right and 17 in the left lung. Thirty were on resection unilateral and solitary. There was no operative mortality and the postoperative morbidity was neglectable. The cumulative 3- and 5-years survival percentages as obtained by the life-table method were 44.6 and 31.2. Better survival rates were found in the age group of 0-40 years and in the group of the sarcomas. Worse results were obtained when the primary tumor was invasive or associated with regional metastases. Resection of metastatic lung lesions larger than 5 cm diameter and especially the resection of multiple lesions gave poorer results. The time-interval between the primary operation and the pulmonary resection had no clear prognostic value. The factors determinating the palliative character of the pulmonary resection had a negative influence on the survival. None of the 9 patients with pulmonary metastasis and secondary intrathoracic lymphatic metastases did survive longer than 3 years. All these patients had a primary carcinoma. Out of this study no conclusions can be made as to the extension of the pulmonary resection.
