Preoperative vs Postoperative IMRT for Extremity/Truncal STS
“Preoperative vs Postoperative IMRT for Extremity/Truncal STS”
This study is designed to determine if preoperative image guided radiation therapy (IGRT) delivered using intensity modulated radiation therapy (IMRT) followed by surgery results in similar short-term wound healing complications as surgery followed by postoperative IGRT in patients with extremity or truncal soft tissue sarcoma. Half of the patients will receive preoperative radiotherapy, half will receive postoperative radiotherapy.
Radiation - Preoperative intensity modulated radiation therapy
50 Gy delivered in 25 fractions 4-6 weeks prior to surgical excision
Radiation - Postoperative intensity modulated radiation therapy
Surgery followed by 50 Gy delivered in 25 fractions within 6 weeks of surgery for patients with negative margins; for patients with positive margins a boost of 16 Gy in 8 fractions will be added.
