IsoRay Announces World's First Cesium-131 Mesh Treatment for Meningioma Brain Tumors

RICHLAND, WA, Jun 05, 2012 (MARKETWIRE via COMTEX) -- IsoRay Inc. ISR -2.69% , 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 American Brain Tumor Association, 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 Cesium-131 brachytherapy sutured mesh implant was performed on a female patient suffering from her fourth reoccurrence of a meningioma. 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.
