Glioblastoma, or malignant glioma, is the most common malignant brain tumor, and also the most deadly, because it is very resistant to treatment. In general, current treatments have not yielded significant increases in survival rates, which is why research into novel therapies is so crucial. A novel brain tumor vaccine clinical trial study conducted at UCLA demonstrates a longer survival time in patients with glioblastoma.

Tumors of the pituitary gland, often referred to as “the master gland” can cause striking physical, mental and psychological debilitation in patients. Researchers at Brigham and Women’s Hospital in Boston analyzed the value of fluorescence endoscopy in visually differentiating pituitary tumors from surrounding areas and its potential for improved tumor resection.

Thousands of Americans suffer from episodes of acute or persistent neck and arm pain every year as a result of underlying cervical disc disease. Anterior cervical discectomy and fusion (ACDF) has been the mainstay treatment for many years. This is the largest combined analysis of class 1 data to date comparing the efficacy of artificial disc surgery (arthroplasty) to the ACDF procedure.
