Surgical removal of one or several metastases with a potentially curative aim is possible in the case of isolated pulmonary metastases. Surgery is part of a combined oncological concept. Between 1972 and 1986, surgical resection was indicated in 368 patients and 419 thoracotomies were carried out. Of the patients, 38% had more uni- or bilateral metastases than expected even after the most careful preoperative diagnostic examinations. The 5-year survival probability of all patients operated on was 33%. Corresponding to a differentiation between potentially curative and non-curative resections, the operation was classified as potentially curative in 73%. In this group, the 5- year survival was 39%. Differentiation into tumour groups (carcinomas of caval type, carcinomas of portal type and sarcomas) revealed no statistically significant differences in prognosis. Due to the excellent chemotherapeutical regimens, testicular teratomas achieved the best results in the early postoperative years. Long-term survival is decisively influenced by the removal of all visible and palpable metastases. If complete removal of all tumour tissue is possible, the number of metastases does not influence survival significantly. Besides radicality, the duration of the disease-free interval showed prognostic differences which were statistically significant (P less than 0.001). Considering the metastatic route and the type of primary tumour, there were slight prognostic differences which were not statistically significant. Recently, the median sternotomy has become the preferred method of access. Predominating resection procedures are wedge and segmental resections which yield the best survival rates.
