Intensive combined therapy may help achieve long-term survival in STS subtype
Long-term survival is achievable in a significant proportion of patients with localized synovial sarcoma (SaSy) treated with intensive combined therapy, according to a study.
In this study, 171 patients with stage II/III SaSy were treated with chemotherapy consisting of 4 cycles of ifosfamide 12 g/m2 and 2 cycles of a doxorubicin-based regimen 75 mg/m2. Neoadjuvant radiotherapy was administered on all patients who did not undergo amputation.
In 70% of patients included in this study, tumor size was >5 cm. The 5-year overall survival (OS) was 75%, the local relapse-free survival rate was 80%, and metastasis-free survival rate was 60%.
Patients older than 35 years of age, male, with a large tumor, and a histology other than monophasic were more likely to have worse OS.
