How Does Avastin Work on Brain Tumors?
Avastin (bevacizumab) is an anti-angiogenic drug that works by blocking the formation of new blood vessels in the body. It has been approved by the FDA for the treatment of various cancers including glioblastoma, the most common and aggressive type of brain tumor.
- Avastin targets VEGF protein – Tumors require sufficient supply of nutrients and oxygen, which are transported through blood vessels. Vascular endothelial growth factor (VEGF) is a protein that stimulates the growth of new blood vessels. Avastin specifically targets and binds to VEGF, preventing it from stimulating the formation of new blood vessels.
- Reduced blood supply to tumors – By blocking the formation of new blood vessels, Avastin reduces the blood supply to tumors, starving them of essential nutrients and oxygen.
- Increased tumor cell death – When tumors are deprived of nutrients and oxygen, they may become more susceptible to undergoing cell death or apoptosis. This may contribute to tumor shrinkage.
It’s worth noting that while Avastin may be effective in reducing tumor size and slowing the growth of brain tumors, it is not a cure. It also has potential side effects, such as high blood pressure, bleeding, and impaired wound healing.
The Effectiveness of Avastin on Shrinking Brain Tumors

Alternatives to Avastin for Brain Tumor Patients
Avastin, also known as bevacizumab, is one of the many drugs used to treat brain tumors. Unfortunately, not all patients respond to this treatment. In such cases, other treatments might be considered.
- Chemotherapy: Chemotherapy is a treatment that involves using drugs to kill cancer cells that might have spread to other parts of the body. It is given either orally or intravenously. Some of the most commonly used chemotherapy drugs for brain tumors include temozolomide, procarbazine, and lomustine.
- Radiation Therapy: Radiation therapy is a treatment that uses high-energy rays to kill cancer cells. It is commonly used in combination with other treatments such as chemotherapy. In the case of brain tumors, it is typically given in fractions over a period of several weeks. Benefits of radiation therapy can be seen in both the reduction of tumor size and overall improvement in patient symptoms. Metastatic brain tumors, however, can sometimes be less responsive to radiation therapy than primary brain tumors.
- Targeted Therapy: Targeted therapy involves using drugs that target specific molecules found in cancer cells. This helps to identify cells that are dividing rapidly compared to other cells in the body. While more commonly used to treat other forms of cancer, targeted therapy is available for treating brain cancer, particularly EGFR mutations accompanied by ALK rearrangements. Some examples of targeted therapies include cetuximab, lapatinib, and gefitinib.
- Immunotherapy: The immune system helps fight infections and diseases in the body. Immunotherapy involves using drugs that help the immune system to recognize and attack cancer cells. This therapy can sometimes be effective in treating certain types of brain tumors such as glioblastoma multiforme. Some immunotherapy approaches include checkpoint inhibitors and CAR T cells.
- Surgery: Surgery to remove brain tumors is often the first line of treatment approach, particularly for patients whose tumor can be removed completely. Even for inoperable cases, biopsy might be taken from the tumor to determine the type of tumor as well as the genetic markers that it contains. The biopsy findings can then characterize the tumor which helps in determining the best options available.
