1. Explain three types of standard treatment are used?
Surgery: Surgery is used, when possible, to treat adult brain tumor, as described in the Description section of this summary.
Radiation therapy: Radiation therapy is a cancer treatment that uses high-energy X-rays or other types of radiation to kill cancer cells. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy: Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). A dissolving wafer may be used to deliver an anticancer drug directly into the brain tumor site after the tumor has been removed by surgery. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
2. Do you know how are adult brain tumors treated?
Different types of treatment are available for patients with adult brain tumor. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. Before starting treatment, patients may want to think about taking part in a clinical trial. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.
3. Explain Metastatic Brain Tumors?
Treatment of a single metastatic brain tumor is usually surgery followed by radiation therapy to the brain.
Treatment of more than one metastatic brain tumor may include the following:
Radiation therapy to the brain.
Surgery, for large tumors that are pressing on areas of the brain and causing symptoms.
4. Explain Recurrent Adult Brain Tumor?
Treatment of recurrent adult brain tumors may include the following:
Surgery with or without chemotherapy.
Radiation therapy, if not used during previous treatment, with or without chemotherapy.
Internal radiation therapy.
Chemotherapy.
A clinical trial of new anticancer drugs.
A clinical trial of chemotherapy placed into the brain during surgery.
A clinical trial of biologic therapy.
Surgery with or without radiation therapy. Sometimes special drugs other than chemotherapy may be used to control symptoms from these tumors.
Treatment of craniopharyngiomas may include the following:
Surgery to remove the entire tumor.
Surgery to remove as much of the tumor as possible, followed by radiation therapy.
Treatment of central nervous system germ cell tumors depends on the type of cancer cells, the location of the tumor, whether the cancer can be removed in an operation, and other factors.
Treatment of meningiomas may include the following:
Surgery with or without radiation therapy.
Radiation therapy for tumors that cannot be removed by surgery.
Treatment of malignant meningioma may include the following:
Surgery plus radiation therapy.
A clinical trial of external radiation therapy plus hyperthermia therapy or new methods of delivering radiation therapy.
A clinical trial of new anticancer drugs and/or biologic therapy following radiation therapy.
9. Explain Pineal Parenchymal Tumors?
Treatment of pineal parenchymal tumors may include the following:
Surgery plus radiation therapy with or without chemotherapy.
A clinical trial of external radiation therapy plus hyperthermia therapy or new methods of delivering radiation therapy.
A clinical trial of new anticancer drugs and biologic therapy following radiation therapy.
Treatment of medulloblastomas may include the following:
Surgery plus radiation therapy to the brain and spine.
A clinical trial of surgery and radiation therapy to the brain and spine for tumors that are more difficult to treat successfully.
A clinical trial of chemotherapy.
