what research (or clinical trials) is being done for Adult Primary Liver Cancer ? 

New types of treatment are being tested in clinical trials.
                    Information about clinical trials is available from the NCI website.
                
                
                    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 listing of clinical trials.
What causes Childhood Ependymoma ? 

The cause of most childhood brain tumors is unknown.
What are the symptoms of Childhood Ependymoma ? 

The signs and symptoms of childhood ependymoma are not the same in every child. Signs and symptoms depend on the following:         - The child's age.    - Where the tumor has formed.        Signs and symptoms may be caused by childhood ependymoma or by other conditions. Check with your child's doctor if your child has any of the following:         - Frequent headaches.    -  Seizures.    - Nausea and vomiting.    - Pain or stiffness in the neck.    - Loss of balance or trouble walking.    - Weakness in the legs.    - Blurry vision.    - Back pain.    - A change in bowel function.    - Trouble urinating.    -  Confusion or irritability.
How to diagnose Childhood Ependymoma ? 

Tests that examine the brain and spinal cord are used to detect (find) childhood ependymoma. 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 patients 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 persons 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.    -   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 areas inside the brain and spinal cord. A substance called gadolinium is injected into a vein and travels through the bloodstream. 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).    -   Lumbar puncture : A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of fluid. The sample of CSF is checked under a microscope for signs of tumor cells. The sample may also be checked for the amounts of protein and glucose. A higher than normal amount of protein or lower than normal amount of glucose may be a sign of a tumor. This procedure is also called an LP or spinal tap.
                    Childhood ependymoma is diagnosed and removed in surgery. If the diagnostic tests show there may be a brain tumor, a biopsy is done by removing part of the skull and using a needle to remove a sample of the brain tissue. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor will remove as much tumor as safely possible during the same surgery.     The following test may be done on the tissue that was removed:         -   Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between brain stem glioma and other brain tumors.         An MRI is often done after the tumor is removed to find out whether any tumor remains.
What is the outlook for Childhood Ependymoma ? 

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on:         - Where the tumor has formed in the central nervous system (CNS).    - Whether there are certain changes in the genes or chromosomes.    - Whether any cancer cells remain after surgery to remove the tumor.     - The type of ependymoma.     - The age of the child when the tumor is diagnosed.     - Whether the cancer has spread to other parts of the brain or spinal cord.     - Whether the tumor has just been diagnosed or has recurred (come back).         Prognosis also depends on the type and dose of radiation therapy that is given.

What are the stages of Childhood Ependymoma ? 

Key Points
                    - The area where the tumor is found and the childs age are used in place of a staging system to plan cancer treatment.    - The information from tests and procedures done to detect (find) childhood ependymoma is used to plan cancer treatment.
                
                
                    The area where the tumor is found and the childs age are used in place of a staging system to plan cancer treatment.
                    Staging is the process used to find out how much cancer there is and if cancer has spread. There is no standard staging system for childhood ependymoma. Treatment is based on where the cancer is in the body and the age of the child.

                    Some of the tests used to detect childhood ependymoma are repeated after the tumor is removed by surgery. (See the General Information section.) This is to find out how much tumor remains after surgery.
What is (are) Oropharyngeal Cancer ? 

Key Points
                    - Oropharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the oropharynx.    - Smoking or being infected with human papillomavirus can increase the risk of oropharyngeal cancer.     - Signs and symptoms of oropharyngeal cancer include a lump in the neck and a sore throat.     - Tests that examine the mouth and throat are used to help detect (find), diagnose, and stage oropharyngeal cancer.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Oropharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the oropharynx.
                    The oropharynx is the middle part of the pharynx (throat), behind the mouth. The pharynx is a hollow tube about 5 inches long that starts behind the nose and ends where the trachea (windpipe) and esophagus (tube from the throat to the stomach) begin. Air and food pass through the pharynx on the way to the trachea or the esophagus.     The oropharynx includes the following:         -  Soft palate.    - Side and back walls of the throat.    -  Tonsils.    - Back one-third of the tongue.          Oropharyngeal cancer is a type of head and neck cancer. Sometimes more than one cancer can occur in the oropharynx and in other parts of the oral cavity, nose, pharynx, larynx (voice box), trachea, or esophagus at the same time.   Most oropharyngeal cancers are squamous cell carcinomas. Squamous cells are the thin, flat cells that line the inside of the oropharynx.   See the following PDQ summaries for more information about other types of head and neck cancers:         -  Hypopharyngeal Cancer Treatment     -  Lip and Oral Cavity Cancer Treatment     -  Oral Cavity and Oropharyngeal Cancer Prevention     -  Oral Cavity and Oropharyngeal Cancer Screening
Who is at risk for Oropharyngeal Cancer? ? 

Smoking or being infected with human papillomavirus can increase the risk of oropharyngeal cancer. Anything that increases your risk 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. Talk with your doctor if you think you may be at risk.   The most common risk factors for oropharyngeal cancer include the following:         - A history of smoking cigarettes for more than 10 pack years and other tobacco use.    - Personal history of head and neck cancer.    - Heavy alcohol use.    - Being infected with human papillomavirus (HPV), especially HPV type 16. The number of cases of oropharyngeal cancers linked to HPV infection is increasing.    - Chewing betel quid, a stimulant commonly used in parts of Asia.
What are the symptoms of Oropharyngeal Cancer ? 

Signs and symptoms of oropharyngeal cancer include a lump in the neck and a sore throat. These and other signs and symptoms may be caused by oropharyngeal cancer or by other conditions. Check with your doctor if you have any of the following:         - A sore throat that does not go away.    - Trouble swallowing.    - Trouble opening the mouth fully.    - Trouble moving the tongue.    - Weight loss for no known reason.    - Ear pain.    - A lump in the back of the mouth, throat, or neck.    - A white patch on the tongue or lining of the mouth that does not go away.    - Coughing up blood.        Sometimes oropharyngeal cancer does not cause early signs or symptoms.
What is the outlook for Oropharyngeal Cancer ? 

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) depends on the following:          -  Whether the patient has HPV infection of the oropharynx.    - Whether the patient has a history of smoking cigarettes for ten or more pack years.     -  The stage of the cancer.    -  The number and size of lymph nodes with cancer.        Oropharyngeal tumors related to HPV infection have a better prognosis and are less likely to recur than tumors not linked to HPV infection.   Treatment options depend on the following:         - The stage of the cancer.    - Keeping the patient's ability to speak and swallow as normal as possible.    - The patient's general health.        Patients with oropharyngeal cancer have an increased risk of another cancer in the head or neck. This risk is increased in patients who continue to smoke or drink alcohol after treatment.   See the PDQ summary Cigarette Smoking: Health Risks and How to Quit for more information.

What is (are) Childhood Craniopharyngioma ? 

Key Points
                    - Childhood craniopharyngiomas are benign brain tumors found near the pituitary gland.    - There are no known risk factors for childhood craniopharyngioma.    - Signs of childhood craniopharyngioma include vision changes and slow growth.    - Tests that examine the brain, vision, and hormone levels are used to detect (find) childhood craniopharyngiomas.    - Childhood craniopharyngiomas are diagnosed and may be removed in the same surgery.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Childhood craniopharyngiomas are benign brain tumors found near the pituitary gland.
                    Childhood craniopharyngiomas are rare tumors usually found near the pituitary gland (a pea-sized organ at the bottom of the brain that controls other glands) and the hypothalamus (a small cone-shaped organ connected to the pituitary gland by nerves).     Craniopharyngiomas are usually part solid mass and part fluid -filled cyst. They are benign (not cancer) and do not spread to other parts of the brain or to other parts of the body. However, they may grow and press on nearby parts of the brain or other areas, including the pituitary gland, the optic chiasm, optic nerves, and fluid-filled spaces in the brain. Craniopharyngiomas may affect many functions of the brain. They may affect hormone making, growth, and vision. Benign brain tumors need treatment.    This summary is about the treatment of primary brain tumors (tumors that begin in the brain). Treatment for metastatic brain tumors, which are tumors formed by cancer cells that begin in other parts of the body and spread to the brain, is not covered in this summary. See the PDQ treatment summary on Childhood Brain and Spinal Cord Tumors Treatment Overview for information about the different types of childhood brain and spinal cord tumors.   Brain tumors can occur in both children and adults; however, treatment for children may be different than treatment for adults. (See the PDQ summary on Adult Central Nervous System Tumors Treatment for more information.)
Who is at risk for Childhood Craniopharyngioma? ? 

There are no known risk factors for childhood craniopharyngioma. Craniopharyngiomas are rare in children younger than 2 years of age and are most often diagnosed in children aged 5 to 14 years. It is not known what causes these tumors.
What are the symptoms of Childhood Craniopharyngioma ? 

Signs of childhood craniopharyngioma include vision changes and slow growth. These and other signs and symptoms may be caused by craniopharyngiomas or by other conditions. Check with your childs doctor if your child has any of the following:         - Headaches, including morning headache or headache that goes away after vomiting.    - Vision changes.    -  Nausea and vomiting.    - Loss of balance or trouble walking.    - Increase in thirst or urination.    - Unusual sleepiness or change in energy level.    - Changes in personality or behavior.    - Short stature or slow growth.    - Hearing loss.    - Weight gain.
What is the outlook for Childhood Craniopharyngioma ? 

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following:          - The size of the tumor.    - Where the tumor is in the brain.    - Whether there are tumor cells left after surgery.    - The child's age.    -  Side effects that may occur months or years after treatment.    - Whether the tumor has just been diagnosed or has recurred (come back).
What are the stages of Childhood Craniopharyngioma ? 

The process used to find out if cancer has spread within the brain or to other parts of the body is called staging. There is no standard system for staging childhood craniopharyngioma. Craniopharyngioma is described as newly diagnosed disease or recurrent disease. The results of the tests and procedures done to diagnose craniopharyngioma are used to help make decisions about treatment.
what research (or clinical trials) is being done for Childhood Craniopharyngioma ? 

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 medical research process. Clinical trials are done to find out if new treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments 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 diseases 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.   Check the list of NCI-supported cancer clinical trials that are now accepting patients with childhood craniopharyngioma. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website.

What is (are) Transitional Cell Cancer of the Renal Pelvis and Ureter ? 

Key Points
                    - Transitional cell cancer of the renal pelvis and ureter is a disease in which malignant (cancer) cells form in the renal pelvis and ureter.    -  Misuse of certain pain medicines can affect the risk of transitional cell cancer of the renal pelvis and ureter.     - Signs and symptoms of transitional cell cancer of the renal pelvis and ureter include blood in the urine and back pain.    - Tests that examine the abdomen and kidneys are used to detect (find) and diagnose transitional cell cancer of the renal pelvis and ureter.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Transitional cell cancer of the renal pelvis and ureter is a disease in which malignant (cancer) cells form in the renal pelvis and ureter.
                    The renal pelvis is the top part of the ureter. The ureter is a long tube that connects the kidney to the bladder. There are two kidneys, one on each side of the backbone, above the waist. The kidneys of an adult are about 5 inches long and 3 inches wide and are shaped like a kidney bean. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine collects in the middle of each kidney in the renal pelvis. Urine passes from the renal pelvis through the ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body.      The renal pelvis and ureters are lined with transitional cells. These cells can change shape and stretch without breaking apart. Transitional cell cancer starts in these cells. Transitional cell cancer can form in the renal pelvis or the ureter or both.    Renal cell cancer is a more common type of kidney cancer. See the PDQ summary about Renal Cell Cancer Treatment for more information.
What are the symptoms of Transitional Cell Cancer of the Renal Pelvis and Ureter ? 

Signs and symptoms of transitional cell cancer of the renal pelvis and ureter include blood in the urine and back pain. These and other signs and symptoms may be caused by transitional cell cancer of the renal pelvis and ureter or by other conditions. There may be no signs or symptoms in the early stages. Signs and symptoms may appear as the tumor grows. Check with your doctor if you have any of the following:         - Blood in the urine.    - A pain in the back that doesn't go away.    - Extreme tiredness.    -  Weight loss with no known reason.     - Painful or frequent urination.
