Abstract
The results of surgical management of 63 cases of pulmonary metastases from bone and soft tissue sarcomas, admitted at the Istituto Nazionale Tumori of Milan, between 1970 and 1987, are reviewed in this paper. To estimate the relative impact of metastasectomy on the overall performance of treatment, survival curves were calculated from the time of first thoracotomy, as well as from the initial treatment of primary sarcoma. In the present series, total actuarial survival at 10 years was 37% for osteosarcoma, 27% for soft tissue sarcomas, and 24% for the other bone sarcomas, with a median survival of 48, 56, and 36 months, respectively. Five‐year survival from the first pulmonary resection was influenced by the number of metastases and the length of the first disease‐free interval only in osteosarcoma, while in soft tissue sarcomas a major untoward factor was represented by local recurrence at the site of the primary tumor. These data support the concept of pulmonary metastasectomy as effective salvage therapy for radically treated sarcomas; this management can rescue a significant proportion of all relapsed patients.
