Neoadjuvant chemoradiation therapy for soft tissue sarcomas of the extremities
INTRODUCTION AND OBJECTIVE: Neoadjuvant and adjuvant therapies for soft tissue sarcomas of the extremities are still controversial. The aim of this study was to analyze the results of a protocol of neoadjuvant chemoradiation therapy for extremity sarcomas. METHODS: A retrospective analysis was carried out in a consecutive series of 49 adult patients with advanced extremity soft tissue sarcomas that could not be resected with adequate margins during the primary resection. All patients were treated with a protocol of preoperative radiation therapy at a total dose of 30 Gy, concomitant with doxorubicin (60 mg/m²) chemotherapy. The main endpoints assessed were local recurrence-free survival, metastasis-free survival and overall survival. The median follow-up time was 32.1 months. RESULTS: The five-year local recurrence-free survival, metastasis-free survival and overall survival rates were 81.5%, 46.7% and 58.3%, respectively. For high-grade tumors, the five-year metastasis-free and overall survival rates were only 36.3% and 41.2%, respectively. Severe wound complications were observed in 41.8% of the patients who underwent surgery. These complications precluded adjuvant chemotherapy in 73.7% (14/19) of the patients eligible to receive it. CONCLUSIONS: In this study, neoadjuvant chemoradiation therapy was associated with a good local control rate, but the distant relapse-free rate and overall survival rate were still poor. The high rate of wound complications modified the planning of adjuvant treatment in most patients.
