Clinical trials are an important treatment possibility, especially for patients with tumors that are inoperable or do not respond well to treatment. Participation in clinical trials also gives patients an opportunity to make contributions to the search to find a cure for their cancer. A wide variety of clinical trials are available, particularly for the higher-grade astrocytomas. Trials for higher-grade astrocytomas may test new drugs, new combinations of drugs, drug implants, and higher doses of drugs, possibly in combination with different methods of radiation therapy. Some studies may examine the use of gene therapy or immune therapy, including vaccines.
Trials for lower-grade astrocytomas focus on finding chemotherapy that causes fewer side effects. Some studies may also feature new combinations of drugs while others may attempt to treat the tumor by using lower dosages of drugs spread out over a longer period of time.
