Glioma is a broad category of brain and spinal cord tumors that come from glial cells, brain cells that can develop into tumors.
The symptoms, prognosis, and treatment of a malignant glioma depend on the person’s age, the exact type of tumor, and the location of the tumor within the brain. These tumors tend to grow and infiltrate into the normal brain tissue, which makes surgical removal very difficult -- or sometimes impossible -- and complicates treatment.
These brain tumors are often diagnosed...
Some reports indicate that as many as 88% of pituitary carcinomas are endocrinologically active, and adrenocorticotrophin hormone-secreting tumors are the most common. Treatments for patients with pituitary carcinomas are palliative, with the mean survival time ranging from 2 years to 2.4 years, though several case reports of long-term survivors have been published.[2,3,4,5]
Treatment options for patients with pituitary carcinomas include resection and dopamine agonists for PRL-producing tumors; somatostatin analogues for GH-producing and TSH-producing tumors; radiation therapy, and chemotherapy. These treatments are palliative with the mean survival time ranging from 2 years to 2.4 years, though several case reports of long-term survivors have been published.[2,3,4,5]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with pituitary tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
