In-depth feasibility study on conservative surgery, perioperative high-dose-rate brachytherapy, and external beam radiation therapy, with a focus on interstitial brachytherapy for soft tissue sarcomas: Insights from a single-institute experience.

Purpose: Soft tissue sarcomas (STS) due to their aggressive nature, pose challenges in achieving optimal local control (LC) rates following surgery. Brachytherapy offers precise delivery of high radiation doses to target tissues, potentially enhancing LC rates. This feasibility study explored the efficacy of perioperative high-dose-rate brachytherapy (PHDRB) and external beam radiation therapy (EBRT) in improving LC rates for STS, with a particular focus on interstitial brachytherapy and dose escalation strategies for high-risk patient sub-groups.
