PURPOSE To describe a novel source-delivery system for intraoperative brachytherapy in patients with early-stage lung cancer that is readily adaptable to a video-assisted thoracoscopic surgery approach and can be precisely delivered to achieve optimal dose distribution. METHODS AND MATERIALS Radioactive ytterbium-169 ((169)Yb) was sealed within a titanium(More)
PURPOSE After vertebral or paravertebral tumor resection, tumor cells may remain on the dura. Because a tumoricidal dose is difficult to achieve using external beam radiotherapy without exceeding the spinal cord tolerance, we developed intraoperative applicators to deliver additional dose to the dura. METHODS AND MATERIALS Eight patients with vertebral or(More)
PURPOSE A novel (32)P brachytherapy source has been in use at our institution intraoperatively for temporary radiation therapy of the spinal dura and other localized tumors. We describe the dosimetry and clinical implementation of the source. METHODS AND MATERIALS Dosimetric evaluation for the source was done with a complete set of MCNP5 Monte Carlo(More)
