Adult Brain Tumors Treatment
General Information About Adult Brain Tumors
An adult brain tumor is a disease in which abnormal cells form in the tissues of the brain.
There are many types of brain and spinal cord
tumors
. The tumors are formed by the abnormal
growth of cells
and may begin in different parts of the brain or spinal cord. Together, the brain and spinal cord make up the central nervous system
(CNS).
The tumors may be benign
(not cancer
) or malignant
(cancer). Benign brain tumors
grow and press on nearby areas of the brain. They rarely spread into other tissues
and may recur
(come back). Malignant brain tumors are likely
to grow quickly and spread into other brain tissue. When a tumor grows into or presses on an area of the brain, it may keep that part of the brain from working the way it should. Both benign and malignant brain tumors can cause symptoms
and, sometimes, death.
Brain tumors can occur in both adults and children. However, treatment for
children may be different than treatment for adults. (See the PDQ
summary
on Childhood Brain and Spinal Cord Tumors Treatment Overview for more information on the treatment of children.)
For information about lymphoma
that begins in the brain, see the PDQ summary on Primary CNS Lymphoma Treatment.
A brain tumor that starts in another part of the body and spreads to the brain is called a metastatic tumor.
Tumors that start in the brain are called primary
brain tumors.
Often, tumors found in the brain have started somewhere else in the body and spread to one or more parts of the brain. These are called metastatic
brain tumors (or brain metastases). Metastatic
brain tumors are more common than primary brain tumors.
The types of cancer that commonly spread to the brain are melanoma
and cancer of the breast
, colon
, lung
, and unknown primary site. The types of cancer that commonly spread to the spinal cord are lymphoma and cancer of the lung, breast, and prostate
. About half of metastatic brain and spinal cord tumors are caused by lung cancer
.
Leukemia
, lymphoma, breast cancer
, and gastrointestinal
cancer may spread to the leptomeninges (the two innermost membranes
covering the brain and spinal cord).
See the following PDQ summaries for more information on cancers that commonly spread to the brain and spinal cord:

The brain controls many important body functions.
The brain has three major parts:
- The cerebrum
is the largest part of the brain. It is at the top of the head. The cerebrum controls thinking, learning, problem solving, emotions, speech, reading, writing, and voluntary movement.
- The cerebellum
is in the lower back of the brain (near the middle of the back of the head). It controls movement, balance, and posture.
- The brain stem
connects the brain to the spinal cord. It is in the lowest part of the brain (just above the back of the neck). The brain stem controls breathing, heart rate, and the nerves
and muscles used in seeing, hearing, walking, talking, and eating.
The spinal cord connects the brain to nerves in most parts of the body.
The spinal cord is a column of nerve tissue that runs from the brain stem down the center of the back. It is covered by three thin layers of tissue called membranes. These membranes are surrounded by the vertebrae
(back bones). Spinal cord nerves carry messages between the brain and the rest of the body, such as a signal from the brain to cause muscles to move or from the skin to the brain about the sense of touch.
There are different types of brain and spinal cord tumors.
Brain and spinal cord tumors are named based on the type of cell they formed in and where the tumor first formed in the CNS
. The grade
of a tumor may be used to tell the difference between slow- and fast-growing types of the tumor. The grade of a tumor is based on how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread.
Tumor Grading System- Grade I (low-grade
) — The tumor grows slowly, has cells that look a lot like normal cells, and rarely spreads into nearby tissues. It may be possible to remove the entire tumor by surgery
.
- Grade II — The tumor grows slowly, but may spread into nearby tissue and may recur (come back). Some tumors may become a higher-grade tumor.
- Grade III — The tumor grows quickly, is likely to spread into nearby tissue, and the tumor cells look very different from normal cells.
- Grade IV (high-grade
) — The tumor grows and spreads very quickly and the cells do not look like normal cells. There may be areas of dead cells in the tumor. Grade IV brain tumors are harder to cure
than lower-grade tumors.
Astrocytic Tumors
An astrocytic tumor
begins in star-shaped brain cells called astrocytes
, which help keep nerve cells
healthy. An astrocyte is a type of glial cell
and is sometimes called a glioma
. Astrocytic tumors include the following:
- Brain stem glioma: A brain stem glioma
forms in the brain stem, which is the part of the brain connected to the spinal cord. It is often a high-grade tumor, which spreads widely through the brain
stem and is hard to cure. A brain stem glioma rarely occurs in adults. (See the PDQ summary on Childhood Brain Stem Glioma Treatment for more information.)
- Pineal astrocytic tumor: A pineal astrocytic tumor
forms in tissue around the pineal gland
and may be any grade. The pineal gland is a tiny organ
in the brain that makes melatonin
, a hormone
that helps control the sleeping and waking cycle.
- Pilocytic astrocytoma (grade I): A pilocytic
astrocytoma
grows slowly in the brain or spinal cord. It may be in the form of a cyst
and
rarely spreads into nearby tissues. This type of tumor is most common in children and young adults and in people with neurofibromatosis type 1
(NF1). A pilocytic astrocytoma rarely causes death.
- Diffuse astrocytoma (grade II): A diffuse
astrocytoma grows slowly, but often spreads into nearby tissues. Sometimes a diffuse astrocytoma progresses
to a higher grade and becomes an anaplastic
astrocytoma or a glioblastoma
. A diffuse astrocytoma can form in any part of the brain but most often forms in the cerebrum. It is most common in young adults and in people with Li-Fraumeni syndrome
. It is also called a low-grade diffuse astrocytoma.
- Anaplastic astrocytoma (grade III): An anaplastic astrocytoma grows quickly and spreads into nearby tissues. An anaplastic astrocytoma may progress to a higher grade and become a glioblastoma. An anaplastic astrocytoma forms most often in the cerebrum and is most common in adults. An anaplastic astrocytoma is also called a malignant astrocytoma or high-grade astrocytoma.
- Glioblastoma (grade IV): A glioblastoma grows and spreads very quickly. A glioblastoma forms most often in the cerebrum. This type of tumor is most common in adults. This type of tumor has a poor prognosis
. It is
also called glioblastoma multiforme.
Oligodendroglial Tumors
An oligodendroglial tumor
begins in brain cells called
oligodendrocytes, which help keep nerve cells healthy. Oligodendrocytes are a type of glial cell and are sometimes called a glioma. Grades of oligodendroglial tumors include the following:
- Oligodendroglioma (grade II): An oligodendroglioma
grows and spreads slowly
and the tumor cells look very much like normal cells. This type of tumor most often forms in the cerebrum. An oligodendroglioma is most common in adults.
- Anaplastic oligodendroglioma (grade III): An anaplastic oligodendroglioma grows quickly and the tumor cells look
very different from normal cells. It may grow in one place or in many places throughout the brain. This type of cancer most often forms in the cerebrum.
Mixed Gliomas
A mixed glioma
is a brain tumor that has two types of tumor cells in it — oligodendrocytes
and astrocytes. This type of tumor most often forms in the cerebrum.
- Oligoastrocytoma (grade II): An oligoastrocytoma
is a slow-growing tumor and the tumor cells don't look very different from normal cells.
- Anaplastic oligoastrocytoma (grade III): The tumor cells in an anaplastic oligoastrocytoma look very different from normal cells.
Ependymal Tumors
An ependymal tumor
usually begins in cells that line the
fluid
-filled spaces in the brain and
around the spinal cord. Ependymal cells are a type of glial cell and are sometimes called a glioma. Grades
of ependymal
tumors include the following:
- Ependymoma (grade I or II): A grade I or II ependymoma
grows slowly and has cells
that look very much like normal cells. There are two types of grade I ependymoma — myxopapillary ependymoma and subependymoma. These tumors are most common in adults. A grade II ependymoma grows in the ventricle
and its connecting paths or in the spinal cord. It is most common in children and young adults and in people with neurofibromatosis type 2
(NF2). (See the PDQ summary on Childhood Ependymoma Treatment for more information.)
- Anaplastic ependymoma (grade III): An anaplastic ependymoma grows very quickly and has a poor prognosis.
Embryonal Cell Tumors: Medulloblastoma (Grade IV)
A medulloblastoma
is a type of embryonal tumor
. The tumor forms in brain cells when the fetus
is beginning to develop. This type of brain tumor often begins in the cerebellum. The tumor may spread from the brain to the spine
through the cerebrospinal fluid
(CSF). A medulloblastoma occurs most often in children or young adults and in people with Turcot syndrome
type 2 or nevoid basal cell carcinoma syndrome
.
See the following PDQ summaries for more information on embryonal tumors in children:
- Childhood Central Nervous System Embryonal Tumors Treatment
- Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment
Pineal Parenchymal Tumors
A pineal parenchymal
tumor forms in parenchymal cells or pineocytes, which are the cells that make up most of the pineal gland. These tumors are different from pineal astrocytic tumors. Grades of pineal parenchymal
tumors include the following:
- Pineocytomas (grade II): A pineocytoma
is a slow-growing pineal tumor that occurs most often in adults.
- Pineoblastomas (grade IV): A pineoblastoma
is a rare tumor that is very likely to spread. This type of tumor is most common in children. (See the PDQ summary on Childhood Central Nervous System Embryonal Tumors Treatment for more information.)
Meningeal Tumors
A meningeal
tumor, also called a meningioma
, forms in the meninges
(thin layers of tissue that cover the
brain and spinal cord). It can form from different types of brain or spinal cord cells. A meningioma is most common in adults. Types of meningeal tumors include the following:
- Meningioma (grade I): A grade I meningioma is the most common type of meningeal tumor. A grade I meningioma is a slow-growing, benign tumor
that forms most often in the dura mater (the layer of tissue that covers the brain and is closest to the skull). It is most common in women.
- Meningioma (grade II and III): This is a rare, malignant meningeal tumor. It grows quickly
and is likely
to spread within the brain and spinal cord. A grade III meningioma is most common in men.
A hemangiopericytoma
is not a meningeal tumor but is treated like a grade II or III meningioma. A hemangiopericytoma usually forms in the dura mater. It often recurs (comes back) after treatment and usually spreads to other parts of the body.
Germ Cell Tumors
A germ cell tumor
forms in germ cells
, which are the cells that develop into sperm
in men or ova (eggs) in women. Germ cell tumors usually form in the center of the brain, near the pineal gland. Germ cell tumors can spread to other parts of the brain and spinal cord. There are different types of germ cell tumors. These include germinomas
, teratomas
, embryonal yolk sac carcinomas
, and choriocarcinomas
. Germ cell tumors can be either benign or malignant.
Most germ cell tumors occur in children and in people with Klinefelter syndrome
.
(See the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview for more information.)
Tumors of the Sellar Region: Craniopharyngioma (Grade I) and Pituitary Tumor
A tumor of the sellar region begins in the center of the brain, just above the back of the nose. It can form from different types of brain or spinal cord cells.
- Craniopharyngioma (grade I): A craniopharyngioma
is a rare tumor that usually forms just above the pituitary gland
(a pea-sized organ at the bottom of the brain that controls other glands
). The tumor may grow into nearby tissues, including the pituitary gland and optic nerves
. This can affect many functions, including hormone-making and vision. These tumors occur in adults and children. (See the PDQ summary on Childhood Craniopharyngioma Treatment for more information on the treatment of children.)
- Pituitary tumor: See the PDQ summary on Pituitary Tumors Treatment for more information.
Other Adult Brain Tumors
There are many other types of adult brain tumors that are rare and are not discussed in this summary. See the PDQ health professional summary on Adult Brain Tumors Treatment for information about these other types of adult brain tumors:
- Pleomorphic xanthoastrocytoma
- Subependymal giant cell astrocytoma
- Astroblastoma
- Chordoid glioma of the third ventricle
- Gliomatosis cerebri
- Gangliocytoma or ganglioglioma
- Desmoplastic infantile astrocytoma or ganglioglioma
- Dysembryoplastic neuroepithelial tumor
- Central neurocytoma
- Cerebellar liponeurocytoma

- Supratentorial primitive neuroectodermal tumor (PNET)
- Choroid plexus papilloma or carcinoma
- Pineal parenchymal tumors of intermediate differentiation
- Melanocytic lesions
- Capillary hemangioblastoma
- Schwannoma
Recurrent Brain Tumors
A recurrent
brain tumor is a tumor that has recurred (come back)
after it has been treated. Brain tumors often recur, sometimes many years
after the first tumor. The tumor may recur at the same place in the brain or in other parts of the central nervous system.
The cause of most adult brain tumors is unknown.
Anything that increases your chance of getting a disease is called a risk factor
. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. There are few known risk factors for brain tumors. The following conditions may increase the risk of developing certain types of brain tumors:
- Being exposed to vinyl chloride
may increase the risk of glioma.
- Past treatment with radiation therapy
to the scalp or brain may increase the risk of meningioma.
- Infection
with the Epstein-Barr virus
, having AIDS
(acquired immunodeficiency syndrome), or receiving an organ transplant
may increase the risk of primary CNS lymphoma
. (See the PDQ summary
on Primary CNS Lymphoma for more information.)
- Having certain genetic
syndromes may increase the risk of developing the following types of brain tumors:
The symptoms of adult brain and spinal cord tumors are not the same in every person.
The symptoms caused by a brain tumor depend on where the tumor formed in the brain, the functions controlled by that part of the brain, and the size of the tumor. Headaches and other symptoms may be caused by adult brain tumors. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:
Brain Tumors- Morning headache or headache that goes away after vomiting
.
- Frequent nausea
and vomiting.
- Vision, hearing, and speech problems.
- Loss of balance and trouble walking.
- Weakness on one side of the body.
- Unusual sleepiness or change in activity level.
- Unusual changes in personality or behavior.
- Seizures
.
Spinal Cord Tumors- Back pain or pain that spreads from the back towards the arms or legs.
- A change in bowel
habits or trouble urinating
.
- Weakness in the legs.
- Trouble walking.
Tests that examine the brain and spinal cord are used to
detect (find) adult brain tumors.
The following tests and procedures may be used:
- Physical exam
and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
- Neurological exam
: A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person’s mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam.
- Visual field exam: An exam to check a person’s field of vision (the total area in which objects can be seen). This test measures both central vision (how much a person can see when looking straight ahead) and peripheral vision (how much a person can see in all other directions while staring straight ahead). Any loss of vision may be a sign of a tumor that has damaged or pressed on the parts of the brain that affect eyesight.
- Tumor marker
test: A procedure in which a sample of blood, urine, or tissue is checked to measure the amounts of certain substances made by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the body. These are called tumor markers.
- Gene testing
: A laboratory test
in which a sample of blood or tissue is tested for changes in a chromosome
that has been linked with a certain type of brain tumor.
- Lumbar puncture
: A procedure used to collect cerebrospinal fluid from the spinal column
. This is done by placing a needle into the spinal column. The cerebrospinal fluid is viewed under a microscope by a pathologist
to check for signs of cancer. This procedure is also called an LP or spinal tap.
- CT scan
(CAT
scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray
machine. A dye
may be injected
into a vein
or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- MRI
(magnetic
resonance imaging) with gadolinium
: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of the brain and spinal cord. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). Sometimes a procedure called magnetic resonance spectroscopy
(MRS) is done during the MRI scan
. An MRS is used to diagnose
tumors, based on their chemical make-up.
- SPECT
scan (single photon emission computed tomography scan): A procedure that uses a special camera linked to a computer to make a 3-dimensional
(3-D) picture of the brain. A small amount of a radioactive
substance is injected into a vein or inhaled
through the nose. As the substance travels through the blood, the camera rotates around the head and takes pictures of the brain. There will be increased blood flow and more chemical reactions (metabolism
) in areas where cancer cells are growing. These areas will show up brighter in the picture. This procedure may be done just before or after a CT scan.
- PET scan
(positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose
(sugar) is injected into a vein. The PET scanner
rotates around the body and makes a picture of where glucose is being used in the brain. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
- Angiogram
: A procedure to look at blood vessels
and the flow of blood in the brain. A contrast dye is injected into the blood vessel. As the contrast dye moves through the blood vessel, x-rays are taken to see if there are any blockages.
Most adult brain tumors are diagnosed and removed in surgery.
If doctors think there may be a brain tumor, a biopsy
may be done to remove a sample of tissue. For tumors in the brain, the biopsy is done by removing part of the skull and using a needle to remove the tissue sample. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor may remove as much tumor as safely possible during the same surgery. After the surgery, a pathologist checks the cancer cells to find out the type and grade of brain tumor. The grade of the tumor is based on how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread.
A CT scan or MRI may be used to find out if any cancer cells remain after surgery.
The following tests may be done on the tumor tissue that is removed:
- Immunohistochemistry study: A laboratory test in which a substance such as an antibody
, dye, or radioisotope
is added to a sample of cancer tissue to test for certain antigens
. This type of study is used to tell the difference between different types of cancer.
- Light and electron microscopy
: A laboratory test in which cells in a sample of tissue are viewed under regular and high-powered microscopes to look for certain changes in the cells.
- Cytogenetic analysis
: A laboratory test in which cells in a sample of tissue are viewed under a microscope to look for certain changes in the chromosomes
.
Sometimes a biopsy or surgery cannot be done safely because of where the tumor formed in the brain or spinal cord. These tumors are diagnosed based on the results of imaging
tests and other procedures.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options for primary brain tumors depend on the following:
- The type and grade of the tumor.
- Where the tumor is in the brain.
- Whether the tumor can be removed by surgery.
- Whether cancer cells remain after surgery.
- Whether there are certain changes in the chromosomes.
- Whether the cancer has just been diagnosed or has recurred (come back).
- The patient's general health.
The prognosis and treatment options for metastatic brain tumors depend on the following:
- Whether the patient is younger than 60 years.
- Whether there are more than two tumors in the brain or spinal cord.
- Where in the brain or spinal cord the tumors are.
- How well the tumor responds to treatment.
- Whether the primary tumor continues to grow or spread.
The prognosis is better for brain metastases
from breast cancer than from other types of primary cancer. The prognosis is worse for brain metastases from colon cancer
.
Stages of Adult Brain Tumors
There is no standard staging system for adult brain tumors.
The extent or spread of cancer
is usually described as stages
. There is no standard staging
system for brain tumors
. Brain tumors that begin in the brain may spread to other parts of the brain and spinal cord
, but they rarely spread to other parts of the body. Treatment of brain tumors is based on the type of cell
in which the tumor began, where the tumor formed in the central nervous system
, the amount of cancer left after surgery
, and the grade
of the tumor. Treatment of brain tumors that have spread to the brain from other parts of the body is based on the number of tumors in the brain.
Imaging tests may be repeated after surgery to help plan more treatment.
After the tumor is removed in surgery, some of the tests and procedures used to detect the brain tumor may be repeated to find out how much tumor is left.
Treatment Option Overview
There are different types of treatment for patients with adult
brain tumors.
Different types of treatment are available for patients with adult
brain tumors
. Some treatments are standard
(the currently used treatment), and
some are being tested in clinical
trials
. 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.
Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Three types of standard treatment are used:
Surgery
Surgery
is used to diagnose
and treat adult brain tumors, as described in the General Information section of this summary.
Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy
or radiation therapy
after surgery to kill any cancer cells
that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy
.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays
or other types of radiation
to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy
uses a machine outside the body to send radiation toward the cancer. One type of external radiation therapy is hyperfractionated radiation therapy
, in which the total dose
of radiation is divided into small doses given more than once a day. 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 of tumor
and where it is in the brain.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs
to stop the growth of cancer cells, either by killing the cells or by stopping them 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
). Combination chemotherapy
is treatment using more than one anticancer drug. To treat brain tumors, a dissolving wafer
may be used to deliver an anticancer drug directly to the brain tumor site after the tumor has been removed by surgery. The way the chemotherapy is given depends on the type of tumor and where it is in the brain.
New types of treatment are being tested in clinical trials.
This summary section refers to specific treatments under study in clinical trials, but it may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.
Other types of radiation therapy
- Radiosensitizers
: Drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells.
- Hyperfractionated radiation therapy: Hyperfractionated radiation therapy is radiation treatment in which the total dose of radiation is divided into small doses and the treatments are given more than once a day. Hyperfractionated radiation therapy is used as a standard treatment for a brain stem glioma
.
- Accelerated-fraction radiation therapy
: Radiation treatment in which the total dose of radiation is divided into small doses and the treatments are given more than once a day. The total dose of radiation is also given over a shorter period of time (fewer days) compared to standard radiation therapy.
- Intraoperative radiation therapy
: A cancer treatment that uses high-energy x-rays to kill cancer cells during cancer surgery.
- Stereotactic radiosurgery
: A type of radiation therapy that uses a rigid head frame attached to the skull to aim high-dose radiation
beams directly at the tumors. This causes less damage to nearby healthy tissue
. This is also called stereotaxic radiosurgery and radiation surgery. This procedure does not involve surgery.
Hyperthermia therapy
Hyperthermia therapy
is a
treatment in which body tissue is heated above normal temperature to damage and
kill cancer cells or to make cancer cells more sensitive to the effects of
radiation and certain anticancer drugs.
Biologic therapy
Biologic therapy
is a treatment that uses the patient’s immune system
to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial
may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring
(coming back) or reduce the side effects
of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's
clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose
the cancer or to find out the stage
of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred
(come back). These tests are sometimes called follow-up
tests or check-ups.
Treatment Options by Type of Adult Brain Tumor
A link to a list of current clinical trials
is included for each treatment section. For some types or stages

About PDQ
PDQ is a comprehensive cancer database available on NCI's Web site.
PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.
PDQ contains cancer information summaries.
The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.
The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.
Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.
PDQ also contains information on clinical trials.
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Listings of clinical trials are included in PDQ and are available online at NCI's Web site. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237).
