“Our findings show high-dose methotrexate alone or in combination with other chemotherapy drugs is the most effective treatment available for primary central nervous system lymphoma (PCNSL)” said study author Tracy Batchelor, MD, with the Massachusetts General Hospital Cancer Center in Boston. PCNSL can be a potentially curable brain tumor or one in which there can be a long remission.
The research involved 25 adults with newly diagnosed PCNSL who received a high dose of methotrexate every two weeks for four months or until there were no signs of the brain tumor. The participants were then followed for a minimum of 6.5 years.
The article found 52 percent of the participants achieved complete remission and 40 percent of these patients have not relapsed after an average of seven years. The average survival rate of all participants who received methotrexate was 4.5 years. In contrast, the average survival rate for patients who receive radiation therapy for this type of brain tumor is one year.
“Our findings support the role of methotrexate as a critical chemotherapy drug in the treatment of this type of brain tumor,” said Batchelor. “Moreover, it appears some people may achieve a long remission through the methotrexate alone.”
Batchelor says further studies are needed to identify the optimal methotrexate dose and combination therapy that will produce the most effective results with minimum side effects.
The study was supported by the National Cancer Institute and conducted in the New Approaches to Brain Tumor Therapy (NABTT) consortium.
The American Academy of Neurology, an association of more than 20,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson disease, and multiple sclerosis.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
