[Chemotherapy for pulmonary metastases of soft tissue sarcoma].
The role and value of chemotherapy for soft tissue sarcomas remain unclear. Seventeen patients with pulmonary metastatic soft tissue sarcomas underwent treatment with chemotherapy, and the clinical efficacy and prognosis were studied. Six patients with synovial sarcomas, 4 with malignant fibrous histiocytomas, 4 with neurosarcomas, and the remaining 3 patients with leiomyosarcoma, extraskeletal osteosarcoma, and extraskeletal chondrosarcoma, were studied. Cases with small round cell sarcomas were excluded. The chemotherapy agents were ifosfamide in 10 cases, combination of ifosfamide and adriamycin in 5 cases, or cisplatin and adriamycin in 2 cases. Of the 17 patients, seven had partial responses radiographically and five had pulmonary metastases from synovial sarcoma. Eight patients underwent resection of pulmonary metastases following chemotherapy, and they were found to be residual tumor cells histologically. Twelve of the patients died of disease at 6-108 months (median, 30 months) from the time of the initial therapy, and five patients have survived from 1-53 months (median, 30 months). The absolute three-year survival rate, according to the Kaplan-Meier method, for all 17 patients was 39%. In the two cases with no change and progressive disease, all patients were dead within 2 years, while in the seven partial response cases, two patients were dead, four were alive with pulmonary metastases, and only one case was disease-free at this writing. The survival rate for patients with partial response was significantly higher than for patients with no response. Although the cure rate of pulmonary metastatic soft tissue sarcomas is still low, the combination of chemotherapy and surgery has been shown to result in prolonged survival.
