An improved operative technique for placement of brachytherapy catheters in treatment of soft tissue sarcomas

Two patients with malignant soft tissue sarcomas were treated with local excision followed by a combination of brachytherapy and external beam radiation therapy. The involved areas were large resulting in extensive and irregular sites of resection. The individual placement of multiple brachytherapy catheters in such large, irregular contours can be a time-consuming and technically difficult task often resulting in an uneven distribution of the catheters within the sites of resection. We therefore describe a technique of catheter distribution.
