- Radiation therapy plays a central role in the management of many soft tissue sarcomas and allows for a substantial reduction in the extent of surgical resection. The addition of chemotherapy to preoperative irradiation has been investigated
- A total of 45 patients with high-grade, HR, STS of the extremities and body wall were included in this prospective phase II study.
- Patients were treated with MAID chemotherapy plus G-CSF and RT and post-operative chemotherapy.
- 42/45 patients underwent radical surgery. Of them, 34 patients achieved negative surgical margins
- With a median follow up of 2.35 years, 3 patients died of sarcoma, 3 died of second primary, and one died from possible treatment related toxicity
- Toxicities included 66% grade 4 neutropenia, 29% grade 4 thrombocytopenia, and 12% grade 4 skin toxicity
- 26% patients had delayed wound healing
- 2-year local failure was 12.6% and overall survival was 95%
- Short-term outcome of these patients with very high-risk STS treated with aggressive neoadjuvant chemoradiation appear encouraging
- Neoadjuvant MAID chemotherapy plus G-CSF and RT was tolerable.
- The most significant challenge in the management of soft tissue sarcomas is to reduce the mortality related to systemic disease in patients who present with M0 disease.
- Clinical research efforts should be aimed at better selection of candidates for therapy, identification of newer drugs, and improving the methods of implementing the currently available therapeutic approaches.
