Background: Adjuvant radiotherapy has been shown to improve Local control in patients with soft tissue sarcoma. Additional brachytherapy represents a means of enhancing the therapeutic ratio, as biological and dosimetric advantage over single external-beam irradiation (EBRT) can be expected. High-dose-rate intraoperative brachytherapy (I0HDR) as a boost therapy should therefore be able to further diminish the rate of local recurrence even when performing marginal resection. There are sparse data on I0HDR using flab applicators as adjuvant boost to EBRT in combination with marginal resection of soft tissue sarcomas. Patients and Methods: Within a period of 8 years, we prospectively studied 39 adult patients treated by marginal resection, I0HDR using the flab technique and EBRT for soft tissue sarcomas. There were 32 high-grade and seven Low-grade tumors, 35 were > 5 cm. Mean follow-up was 26 months (range 3-59 months). Results: We could not detect any local recurrences. No treatment-related Loss of Limb or Life occurred. There were no neurologic or vascular complications, all patients maintained functioning extremities as evidenced by a mean Muscutoskeletal Tumor Society (MSTS) functional score of 88.5 (70-100). Treatment-related wound morbidity occurred in eleven patients necessitating revision surgery in eight. Metastatic disease developed in seven patients, six of them had died. The 2-year actuarial disease-free survival was 84%. Conclusions: I0HDR using the flab technique in combination with EBRT and marginal resection is an efficient treatment technique Leading to optimal local control rates and Limited functional impairment.
