Metastatic Patterns in Soft-Tissue Sarcomas

Abstract

In 242 patients with recurrent soft-tissue sarcomas, the most common sites of initial recurrence were the primary site in 47.5% of patients and the lungs in 38% of patients. Further recurrences in the course of the disease concerned the lungs, bones, liver, and brain. Total survival and survival after recurrence were influenced by the histologic type, which also affected the site of recurrence. In the management of local recurrence, a five-year disease-free survival rate of 38% was achieved with surgical treatment, while radiation or chemotherapy alone was ineffective. Local recurrences resulted in significantly higher survival rates than those involving other organs. The disease-free interval was a significant prognostic indicator of subsequent survival in the whole group of patients and among those with local recurrence.
