Treatment Options For Brain Tumor Part 1
Various treatments are used to treat brain tumors. The type of treatment recommended depends on the size and type of tumor, the growth rate and the overall health of the patient. Treatment options include surgery, radiotherapy and chemotherapy, targeted biological agents or a combination thereof. Surgical resection (if not dangerous) is usually the first recommendation of treatment to reduce pressure on our brain quickly. This website focuses on radiation therapy for brain tumors.
In the past two decades, researchers have developed new techniques to deliver radiation to the brain tumor while protecting nearby healthy tissue. These treatments include brachytherapy, intensity modulated radiation therapy (IMRT) and radiosurgery.
Radiation therapy may be recommended for tumors sensitive to this treatment. Conventional radiation therapy using external beam X-ray, gamma rays or protons targeted to the tumor to kill cancer cells and shrink brain tumors. Usually occurs in a period of several weeks. The whole brain radiation therapy is an option for multiple tumors.
The following are some new types of radiation:
* Intensity Modulated Radiotherapy (IMRT, for its acronym in English [Intensity-modulated radiation therapy]) is an advanced form of radiation therapy that uses high-precision X-ray accelerators to computer-controlled precise radiation doses to malignant tumors or specific areas within the tumor. The radiation dose is designed to comply with a three-dimensional (3D) of the tumor by modulating (control) of the intensity of the radiation beam to focus a higher dose to the tumor while minimizing exposure to radiation on healthy cells. See page IMRT (www.RadiologyInfo.org/sp/info.cfm?pg=imrt) for more information.
* Stereotactic radiosurgery is a highly accurate form of radiation therapy that directs narrow beams of radiation to the tumor from different angles. In this procedure the patient may place a rigid device in the head. Computed tomography (CT) or nuclear magnetic resonance (NMR) help the doctor identify the exact location of the tumor, and the computer helps to regulate the dose of radiation. Radiation therapy is stereotactic radiosurgery physically similar but involves fractionation (multiple treatments). This method would be recommended for tumors that are at or near critical structures of the brain that can not tolerate a single large dose of radiation or larger tumor.
