One reason the disease is difficult to treat is, by the time it starts causing symptoms, the cancer is usually embedded in the brain by meandering tentacles of malignant tissue. These tendrils are hard to remove while sparing healthy brain tissue, and the tumors often grow back within months of surgery due to cancerous tissue being left behind, Vora said.In a recent clinical trial, Vora and his colleagues focused on improving postsurgical chemotherapy and radiation for glioblastoma patients.
After undergoing surgery, 39 trial participants received this tumor mapping and treatment for one to two weeks; all of the patients were over 65. Despite the typical survival time for the diagnosis being less than a year, 22 of the 39 patients were alive 12 months after the treatment. And instead of a median survival of six to nine months, the patients averaged 13.1 months.
