IsoRay wins FDA nod for GammaTile brain tumor treatment

IsoRay (NYSE:ISR) said today it won FDA 510(k) clearance for its GammaTile brachytherapy technology designed for treating recurrent brain tumors. The Richland, Wash.-based company’s GammaTile is a radiation system using Cesium-131 radiation seeds embedded in a collagen ’tile’ which is designed to be placed in surgical margins at the time of surgery. IsoRay said it had previously inked a collaborative development and ten-year supply agreement for the newly cleared GammaTile with GT Medical Technology, which the company said will be available in the US “in the near future.” “We are very excited that our partnership with IsoRay Medical has resulted in this new opportunity to provide an innovative solution for the hundreds of thousands of patients with recurrent brain tumors. As we worked to gain approval, GammaTile Therapy was implanted in over 100 patients in an IRB- approved study at the Barrow Neurological Institute in Phoenix, AZ.  We believe that experience will be a solid foundation for us to expand access to this important advancement in brain tumor therapy,” GT Medical Technologies prez &CEO Matthew Likens said in a prepared statement. “GammaTile Therapy utilizes Cesium-131 brachytherapy seeds to deliver a fast-acting therapeutic dose to the tumor bed. The unique properties of Cesium-131 have started to revolutionize brain brachytherapy treatment, and GammaTile Therapy should help to accelerate the adoption of...

We present a two parts review discussing the unique features of the elderly patient harboring an intracranial neoplasm. In this Part-I, we review the management of benign meningioma in the elderly population.Meningioma is the second most common primary brain tumor. The risk of developing meningioma increases dramatically after 65 years of age. Predicting a specific meningioma’s growth pattern and clinical behavior is impossible. Clinicians must choose between GTR with associated morbidity/ mortality, SRS or a combined AHS approach, since progression rates after STR are high. Several scoring systems attempt to offer...

Authors: Martelli C, Serra R, Inserra I, Rossetti DV, Iavarone F, Vincenzoni F, Castagnola M, Urbani A, Tamburrini G, Caldarelli M, Massimi L, Desiderio C Abstract Although histologically benign, adamantinomatous craniopharyngioma (AC) pediatric brain tumor is a locally aggressive disease that frequently determines symptoms and hormonal dysfunctions related to the mass effect on the surrounding structures. Another typical feature of this benign neoplasm is the presence of voluminous liquid cysts frequently associated with the solid component. Even if studies have been devoted to the proteomic characterization of th...

A team at Tampere University, Finland has developed a technique using surgical smoke that allows neurosurgeons to ID cancerous tissue during surgery. A new method developed by researchers at Tampere University in Finland helps analyze surgical smoke to distinguish between malignant tissue and health tissue. The researcher’s work was recently published in the Journal of Neurosurgery. The technology is based on differential mobility spectrometry, wherein flue gas ions are fed into an electric field. The distribution of ions in the electric field is tissue-specific, and the tissue can be identified on the ba...

Chow Peter D. Chang Radiographic assessment with magnetic resonance imaging (MRI) is widely used to characterize gliomas, which represent 80% of all primary malignant brain tumors. Unfortunately, glioma biology is marked by heterogeneous angiogenesis, cellular proliferation, cellular invasion, and apoptosis. This translates into varying degrees of enhancement, edema, and necrosis, making reliable imaging assessment challenging. Deep learning, a subset of machine learning artificial intelligence, has gained traction as a method, which has seen effective employment in solving image-based problems, including those in me...
