Clinical Study Discusses Cost Effectiveness of Surgical Resection and IsoRay's Cesium-131 Intraoperative Brachytherapy
RICHLAND, Wash., Jan. 13, 2016 /PRNewswire/ -- IsoRay Inc. (NYSE MKT:ISR), a medical technology company and innovator in seed brachytherapy and medical radioisotope applications for the treatment of prostate, brain, lung, head and neck and gynecological cancers, today announced a peer-reviewed publication of the results of a retrospective study on the cost effectiveness of Cesuim-131 in combination with surgical resection for metastatic brain tumors. While parts of the manuscript were presented at a meeting of the Society for Neuro-Oncology in 2012 in Washington, DC, the research paper - Wernicke, A. Gabriella, et al., "The cost-effectiveness of surgical resection and cesium-131 intraoperative brachytherapy versus surgical resection and stereotactic radiosurgery in the treatment of metastatic brain tumors." DOI 10.1007/s11060-015-2026-4 - was published online on January 2, 2016, in the Journal of Neuro-Oncology.
The patients in the study were treated at New York Presbyterian/Weill Cornell Medical Center between 2008 and 2012. The treatment records as well as hospital and outpatient charts of 49 patients with brain metastases were retrospectively reviewed. These 49 patients were placed into two groups. Twenty-four patients underwent treatment with surgical resection (S) and Cesium-131 (Cs-131) intraoperative brachytherapy, or S + Cs-131, and 25 patients underwent surgical resection (S) and stereotactic radiosurgery (SRS), or S + SRS. Hospital charges, survival, quality adjusted life years (QALY) and incremental cost-effectiveness ratios (ICER) were compared for the two groups.
The study concluded that surgical resection plus Cesium-131 (S + Cs-131) is a more cost effective alternative to surgical resection and stereotactic radiosurgery (S + SRS), with direct hospital costs of treatment of $19,271 for S + Cs-131 and $44,219 for S + SRS. Median survival was greater for S + Cs-131 and resulted in a greater quality adjusted life years (QALY). Relative to S + Cs-131, S + SRS resulted in a negative incremental cost-effectiveness ratio (ICER) as it was more expensive yet provided a lower QALY. Therefore, from a resource allocation perspective, this study concluded that S + Cs-131 for brain metastases is the more cost-effective treatment option while providing a better quality of life.
Bill Cavanagh, IsoRay interim CEO, stated: "This study suggests that surgical resection with intraoperative Cs-131 has proven cost-effectiveness for the treatment of metastatic brain tumors while providing a better quality of life. As the healthcare industry continues to study the effective allocation of health resources, studies such as this one are critical to providing cutting edge treatments in a truly cost-effective manner. Interestingly, the measure used in the study for quality of life was better as well."
