IsoRay Announces World's First Cesium-131 Mesh Treatment for Meningioma Brain Tumors
Seed Sutured Mesh Delivers Impressive Early Results at St. Joseph's Hospital & Medical Center, Barrow Neurological Institute
(firmenpresse) - RICHLAND, WA -- (Marketwire) -- 06/05/12 -- Inc. (NYSE Amex: ISR), a medical technology company and innovator in seed brachytherapy and medical radioisotope applications, today announced another milestone in the treatment of brain tumors using its groundbreaking Cesium-131 (Cs-131) seed sutured mesh for internal radiation therapy. Dr. Kris Alan Smith, surgeon and Medical Director, Gamma Knife Center, supported by Dr. David G. Brachman, Medical Director of Radiation Oncology at St. Joseph's Hospital & Medical Center, Barrow Neurological Institute in Phoenix, Arizona, performed the world's first Cesium-131 brachytherapy seed sutured mesh implant on a female patient suffering from a recurring meningioma tumor.
Meningiomas are an assorted set of tumors that develop in membranous layers surrounding the central nervous system. According to the , meningiomas are the most common primary brain tumor and represent one-third of all brain tumors. These fast growing tumors often reoccur. They cause pressure on the brain, destroying brain cells and causing a variety of health and quality of life problems for the stricken patient. There are both benign and malignant meningioma tumors.
The sutured mesh was placed over the resected tumor at the time of surgery to provide immediate radiation therapy to the entire tumor bed and margins, which is aimed at preventing tumor reoccurrence
Typically, meningiomas require multiple treatments with external beam radiation following surgery. Treatment in this manner represents great complexity and difficulty. Because tumors are often large and irregular in shape, delivering a precise dose of radiation is problematic.
Board certified in both Internal Medicine by the American Board of Internal Medicine as well as Radiation Oncology by the American Board of Radiology, Dr. Brachman said, "Patient acceptance has been very high, and no adverse outcomes have been noted to date." Dr. Brachman also pointed to Cesium-131's distinctive abilities. "Cesium-131 provides a unique biological advantage regarding the timing of radiation, being utilized at the time of the surgery before tumor cells can repopulate, which helps to maximize the therapeutic benefit of radiation treatment," he explained.
Cesium-131 allows for the precise treatment of many different cancers because of its unrivaled blend of high energy and its 9.7 day half-life (its unequaled speed in giving off therapeutic radiation).
IsoRay CEO Dwight Babcock says this is just the latest application in brain tumor treatment representing the continued expansion of use of the Company's pioneering Cesium-131 brachytherapy seeds and liquid isotopes. "We are advancing our domestic and international goal of creating widespread awareness and adoption of Cesium-131. The exceptional results that have been realized in treating such a wide array of cancers is drawing an increasing number of inquiries from the medical community. We believe Cesium-131's ability to fight cancer and improve the quality of life for the men, women, and children who are battling these devastating cancers distinguishes it from other treatment options."
In addition to its CMS codes, Cesium-131 is FDA-cleared and holds a CE mark for international sales in seed form for the treatment of brain cancer, cancer, cancer, cancer, colorectal cancer, cancer, head and neck and other cancers throughout the body. The treatment can be deployed using several delivery methods including single seed applicators, implantable strands and seed sutured mesh, and several new implantable devices including the radiation therapy system, the world's only liquid radiation balloon catheter device used in the treatment of brain .
