These cells later become sperm in the testicles or eggs in the ovaries.</p> <p>This summary is about germ cell tumors that form in parts of the body that are extracranial (outside the brain). Extracranial germ cell tumors usually form in the following areas of the body:</p> <ul style="list-style-type: disc"> <li>Testicles.</li> <li>Ovaries.</li> <li>Sacrum or coccyx (tailbone).</li> <li>Retroperitoneum (area in the back of the abdomen behind the tissue that lines the abdominal wall and covers most of the organs in the abdomen).</li> <li>Mediastinum (area between the lungs).</li> <li>Head and neck.</li> </ul> <p> <img data-hw-resource-path="media/medical/nci/cdr0000770217.jpg" src="https://ixbapi.healthwise.net/Resource/14.3/en-us/media/medical/nci/cdr0000770217.jpg" hw:resource-path="media/medical/nci/cdr0000770217.jpg" alt="Extracranial germ cell tumor; drawing shows parts of the body where extracranial germ cell tumors may form, including the head and neck, mediastinum (the area between the lungs, shown in blue), retroperitoneum (the area behind the abdominal organs, shown in red), sacrum, coccyx, testicles (in males), and ovaries (in females). Also shown are the heart and peritoneum." data-hw-width="460" data-hw-height="300" hw:release-quarter="14.3"> <br> <span class="Size1">Extracranial germ cell tumors form in parts of the body other than the brain. This includes the testicles, ovaries, sacrum (lower part of the spine), coccyx (tailbone), mediastinum (area between the lungs), retroperitoneum (the back wall of the abdomen), and the head and neck.</span> </p> <p>Extracranial germ cell tumors are most common in adolescents, with rates in this age group lower for females than males.</p> <p>For information on intracranial (inside the brain) germ cell tumors, see Childhood Central Nervous System Germ Cell Tumors Treatment.</p> <p>Childhood extracranial germ cell tumors may be benign or malignant.</p> <p>Extracranial germ cell tumors may be benign (noncancer) or malignant (cancer).</p> <p>Childhood extracranial germ cell tumors are grouped as gonadal or extragonadal extracranial tumors. </p> <p>Malignant extracranial germ cell tumors are tumors that form outside the brain. They are gonadal or extragonadal.</p> <p>Gonadal germ cell tumors</p> <p>Gonadal germ cell tumors form in the gonads (testicles and ovaries).</p> <ul style="list-style-type: disc"> <li> <b>Testicular germ cell tumors.</b> Testicular germ cell tumors are divided into two main types, seminoma and nonseminoma. Nonseminomas are usually large and cause signs or symptoms of disease. They tend to grow and spread more quickly than seminomas.<p>Testicular germ cell tumors usually occur before the age of 5 years or in adolescents and young adults. Testicular germ cell tumors in adolescents (11 years and older) and young adults are different from those that form in early childhood.</p></li> <li> <b>Ovarian germ cell tumors</b>. Ovarian germ cell tumors are more common in adolescent girls and young women. Most ovarian germ cell tumors are benign mature teratomas (dermoid cysts). Some ovarian germ cell tumors, such as immature teratomas, dysgerminomas, yolk sac tumors, or mixed germ cell tumors, are malignant.</li> </ul> <p>Extragonadal extracranial germ cell tumors</p> <p>Extragonadal extracranial germ cell tumors form in areas of the body other than the brain or gonads (testicles and ovaries).</p> <p>Most extragonadal extracranial germ cell tumors form along the midline of the body. This includes the following: </p> <ul style="list-style-type: disc"> <li>Sacrum (the large, triangle-shaped bone in the lower spine that forms part of the pelvis).</li> <li>Coccyx (tailbone).</li> <li>Mediastinum (the area between the lungs).</li> <li>Back of the abdomen.</li> <li>Neck.</li> </ul> <p>In children younger than 11 years, extragonadal extracranial germ cell tumors usually occur at birth or in early childhood. Most of these tumors are benign teratomas in the sacrum or coccyx.</p> <p>In older children, adolescents, and young adults (11 years and older), extragonadal extracranial germ cell tumors are often in the mediastinum.</p> <p>There are three types of extracranial germ cell tumors.</p> <p>Extracranial germ cell tumors are also grouped into teratomas, malignant germ cell tumors, and mixed germ cell tumors: </p> <p>Teratomas</p> <p>There are two main types of teratomas:</p> <ul style="list-style-type: disc"> <li> <b>Mature teratomas.</b> These tumors are the most common type of extracranial germ cell tumor. Mature teratomas are benign tumors and not likely to become cancer. They usually occur in the sacrum or coccyx in newborns or in the testicles or ovaries at the start of puberty. The cells of mature teratomas look almost like normal cells under a microscope. Some mature teratomas release enzymes or hormones that cause signs and symptoms of disease.</li> <li> <b>Immature teratomas.</b> These tumors usually occur in areas other than the gonads in young children or in the ovaries at the start of puberty. They have cells that look very different from normal cells under a microscope. Immature teratomas may be cancer and spread to other parts of the body. They often have several different types of tissue in them, such as hair, muscle, and bone. Some immature teratomas release enzymes or hormones that cause signs and symptoms of disease.</li> </ul> <p>Malignant germ cell tumors</p> <p> Malignant germ cell tumors are cancer. There are two main types of malignant germ cell tumors:</p> <ul style="list-style-type: disc"> <li> <b>Seminomatous germ cell tumors.</b> There are three types of seminomatous germ cell tumors:<ul style="list-style-type: disc"><li>Seminomas form in the testicle.</li><li>Dysgerminomas form in the ovary.</li><li>Germinomas form in areas of the body that are not the ovary or testicle, such as the mediastinum.</li></ul></li> <li> <b>Nonseminomatous germ cell tumors.</b> There are four types of nonseminomatous germ cell tumors:<ul style="list-style-type: circle"><li>Yolk sac tumors make a hormone called alpha-fetoprotein (AFP). They can form in the ovary, testicle, or other areas of the body.</li><li>Choriocarcinomas make a hormone called beta-human chorionic gonadotropin (beta-hCG). They can form in the ovary, testicle, or other areas of the body.</li><li>Embryonal carcinomas may make a hormone called beta-hCG. They can form in the testicle or other areas of the body, but not in the ovary.</li><li>Gonadoblastomas can form in the ovary.</li></ul></li> </ul> <p>Mixed germ cell tumors</p> <p>Mixed germ cell tumors are made up of at least two types of malignant germ cell tumor. They can form in the ovary, testicle, or other areas of the body.</p> <p>The cause of most childhood extracranial germ cell tumors is unknown.</p> <p>Having certain inherited disorders can increase the risk of extracranial germ cell tumors.</p> <p>A risk factor is anything that increases the chance of getting a disease. Not every child with one or more of these risk factors will develop an extracranial germ cell tumor. And it will develop in some children who don't have a known risk factor. </p> <p>Possible risk factors for extracranial germ cell tumors include:</p> <ul style="list-style-type: disc"> <li>Having certain genetic syndromes:<ul style="list-style-type: circle"><li>Klinefelter syndrome may increase the risk of germ cell tumors in the mediastinum.</li><li>Swyer syndrome may increase the risk of gonadoblastoma and seminoma.</li><li>Turner syndrome may increase the risk of gonadoblastoma and dysgerminoma.</li></ul></li> <li>Having an undescended testicle may increase the risk of testicular cancer.</li> <li>Having an ovary or testicle that has not formed normally (gonadal dysgenesis) may increase the risk of gonadoblastoma.</li> </ul> <p>Talk with your child's doctor if you think your child may be at risk. </p> <p>Signs of childhood extracranial germ cell tumors depend on where the tumor formed in the body.</p> <p> Different tumors may cause the following signs and symptoms. Other conditions may cause these same signs and symptoms. It's important to check with your child's doctor if your child has:</p> <ul style="list-style-type: disc"> <li>A lump in the neck, abdomen, or lower back.</li> <li>A painless lump in the testicle.</li> <li>Pain in the abdomen or back.</li> <li>Respiratory distress, chest pain, or cough.</li> <li>Fever.</li> <li>Constipation.</li> <li>Trouble urinating.</li> <li>Early puberty.</li> <li>In females, no menstrual periods or unusual vaginal bleeding.</li> </ul> <p>Imaging studies and blood tests are used to diagnose childhood extracranial germ cell tumors.</p> <p>If your child has symptoms that suggest they have an extracranial germ cell tumor, their doctor will need to find out if these are due to cancer or another problem. The doctor will ask when the symptoms started and how often your child has been having them. They will also ask about your child's personal and family medical history and do a physical exam. Depending on these results, they may recommend other tests. If your child is diagnosed with an extracranial germ cell tumor, the results of these tests will help you and your child's doctor plan treatment.</p> <p>The tests used to diagnose extracranial germ cell tumors may include:</p> <ul style="list-style-type: disc"> <li> <b>Serum tumor marker test</b>: A procedure in which a sample of blood is checked to measure the amounts of certain substances released into the blood 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 blood. These are called tumor markers. <p>Some malignant germ cell tumors release tumor markers. The following tumor markers may be used to detect extracranial germ cell tumors: </p><ul style="list-style-type: circle"><li>Alpha-fetoprotein (AFP).</li><li>Beta-human chorionic gonadotropin (beta-hCG).</li></ul> For testicular germ cell tumors, blood levels of the tumor markers help show if the tumor is a seminoma or nonseminoma.</li> <li> <b>Blood chemistry studies</b>: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body, including lactate dehydrogenase. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.</li> <li> <b>Chest x-ray</b>: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.</li> <li> <b>CT scan (CAT scan)</b>: A procedure that makes a series of detailed pictures of areas inside the body, such as the chest or lymph nodes, 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.<br><img data-hw-resource-path="media/medical/nci/cdr0000775531.jpg" src="https://ixbapi.healthwise.net/Resource/14.3/en-us/media/medical/nci/cdr0000775531.jpg" hw:resource-path="media/medical/nci/cdr0000775531.jpg" alt="Computed tomography (CT) scan; drawing shows a child lying on a table that slides through the CT scanner, which takes a series of detailed x-ray pictures of areas inside the body." data-hw-width="460" data-hw-height="300" hw:release-quarter="14.3"><br><span class="Size1">Computed tomography (CT) scan.

An ultrasound transducer connected to a computer is pressed against the skin of the abdomen. The transducer bounces sound waves off internal organs and tissues to make echoes that form a sonogram (computer picture).</span></li> <li> <b>Biopsy</b>: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. Sometimes an incisional biopsy or needle biopsy is done before surgery to remove a sample of tissue. Sometimes the tumor is removed during surgery and then a sample of tissue is removed from the tumor.<p>The following tests may be done on the sample of tissue that is removed:</p><ul style="list-style-type: circle"><li><b>Cytogenetic analysis</b>: A laboratory test in which the chromosomes of cells in a sample of tissue are counted and checked for any changes, such as broken, missing, rearranged, or extra chromosomes. Changes in certain chromosomes may be a sign of cancer. Cytogenetic analysis is used to help diagnose cancer, plan treatment, or find out how well treatment is working. </li><li><b>Immunohistochemistry</b>: A laboratory test that uses antibodies to check for certain antigens (markers) in a sample of a patient's tissue. The antibodies are usually linked to an enzyme or a fluorescent dye. After the antibodies bind to a specific antigen in the tissue sample, the enzyme or dye is activated, and the antigen can then be seen under a microscope. This type of test is used to help diagnose cancer and to help tell one type of cancer from another type of cancer.</li></ul></li> </ul> <p>Certain factors affect prognosis (chance of recovery) and treatment options.</p> <p>The prognosis and treatment options depend on the following:</p> <ul style="list-style-type: disc"> <li>The child's age and general health.</li> <li>The stage of the cancer (whether it has spread to nearby areas, lymph nodes, or to other places in the body).</li> <li>Where the tumor first began to grow.</li> <li>The type of germ cell tumor.</li> <li>How well the tumor responds to treatment.</li> <li>Whether the child has gonadal dysgenesis.</li> <li>Whether the tumor can be completely removed by surgery.</li> <li>Whether the cancer has just been diagnosed or has recurred (come back).</li> </ul> <p>The prognosis for childhood extracranial germ cell tumors, especially ovarian germ cell tumors, is good.</p> </div><div class="HwNavigationSection HwSectionVendor" id="sec-ncicdr0000062857-02"><a class="HwSectionNameTag" name="ncicdr0000062857-02" id="anchor-ncicdr0000062857-02" aria-hidden="true"> </a><h2 class="HwSectionTitle">Stages of Childhood Extracranial Germ Cell Tumors</h2> <p>After a childhood extracranial germ cell tumor has been diagnosed, tests are done to find out if cancer cells have spread from where the tumor started to nearby areas or to other parts of the body. </p> <p>The process used to find out if cancer has spread from where the tumor started to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. In some cases, staging may follow surgery to remove the tumor. </p> <p>The following procedures may be used:</p> <ul style="list-style-type: disc"> <li> <b>MRI (magnetic resonance imaging)</b>: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain or lymph nodes. This procedure is also called nuclear magnetic resonance imaging (NMRI).</li> <li> <b>CT scan (CAT scan)</b>: A procedure that makes a series of detailed pictures of areas inside the body, such as the chest or lymph nodes, 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.</li> <li> <b>Bone scan</b>: A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner.</li> <li> <b>Thoracentesis</b>: The removal of fluid from the space between the lining of the chest and the lung, using a needle. A pathologist views the fluid under a microscope to look for cancer cells.</li> <li> <b>Paracentesis</b>: The removal of fluid from the space between the lining of the abdomen and the organs in the abdomen, using a needle. A pathologist views the fluid under a microscope to look for cancer cells.</li> </ul> <p>The results from tests and procedures used to detect and diagnose childhood extracranial germ cell tumors may also be used in staging.</p> <p>There are three ways that cancer spreads in the body.</p> <p>Cancer can spread through tissue, the lymph system, and the blood:</p> <ul style="list-style-type: disc"> <li>Tissue. The cancer spreads from where it began by growing into nearby areas.</li> <li>Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.</li> <li>Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.</li> </ul> <p>Cancer may spread from where it began to other parts of the body.</p> <p>When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.</p> <ul style="list-style-type: disc"> <li>Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.</li> <li>Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.</li> </ul> <p>The metastatic tumor is the same type of cancer as the primary tumor. For example, if an extracranial germ cell tumor spreads to the liver, the cancer cells in the liver are actually cancerous germ cells. The disease is metastatic extracranial germ cell tumor, not liver cancer.</p> <p>Stages are used to describe the different types of extracranial germ cell tumors.</p> <p>Testicular germ cell tumors in children younger than 11 years</p> <p>The following stages are from the Children's Oncology Group.</p> <ul style="list-style-type: disc"> <li> <b>Stage I</b> <p> In stage I, the cancer is found in the testicle only. The testicle and spermatic cord are completely removed by surgery and all of the following are true:</p> <ul style="list-style-type: disc"> <li>the capsule (outer covering of the tumor) did not rupture (break open) and a biopsy was not done before the tumor was removed; and</li> <li>all lymph nodes are smaller than 1 centimeter in their shortest diameter on a CT scan or MRI.</li> </ul> </li> <li> <b>Stage II</b> <p>In stage II, the testicle and spermatic cord are removed by surgery and one of the following is true:</p> <ul style="list-style-type: disc"> <li>the capsule (outer covering of the tumor) ruptured (broke open) or a biopsy was done before surgery; or</li> <li>cancer that can only be seen with a microscope remains in the scrotum or in the spermatic cord near the scrotum, and after surgery, tumor marker levels do not return to normal or do not decrease.</li> </ul> <p>Cancer has not spread to the lymph nodes.</p> </li> <li> <b>Stage III</b> <p>In stage III, one of the following is true:</p> <ul style="list-style-type: disc"> <li>the cancer has spread to one or more lymph nodes at the back of the abdomen; or</li> <li>lymph nodes are at least 2 centimeters wide or are larger than 1 centimeter but smaller than 2 centimeters in their shortest diameter and either have not changed or are growing when a CT scan or MRI is repeated within 4 to 6 weeks.</li> </ul> </li> <li> <b>Stage IV</b> <p>In stage IV, the cancer has spread to other parts of the body, such as the liver, lung, bone, and brain.</p> </li> </ul> <p>Testicular germ cell tumors in adolescents and young adults 11 years and older</p> <p>In males older than 15 years, there are only stage I tumors and metastatic 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.</p> <p>Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment. </p> <p>Children with extracranial germ cell tumors should have their treatment planned by a team of health care providers who are experts in treating cancer in children.</p> <p>Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other health care providers who are experts in treating children with extracranial germ cell tumors and who specialize in certain areas of medicine. These may include the following specialists:</p> <ul style="list-style-type: disc"> <li>Pediatrician.</li> <li>Pediatric surgeon.</li> <li>Pediatric hematologist.</li> <li>Radiation oncologist.</li> <li>Endocrinologist.</li> <li>Pediatric nurse specialist.</li> <li>Rehabilitation specialist.</li> <li>Child life professional.</li> <li>Psychologist.</li> <li>Social worker.</li> <li>Geneticist.</li> <li>Fertility specialist.</li> </ul> <p>The following types of treatment are used:</p> <p>Surgery</p> <p>Surgery to completely remove the tumor is done whenever possible. If the tumor is very large, chemotherapy may be given first, to make the tumor smaller and decrease the amount of tissue that needs to be removed during surgery. A goal of surgery is to keep reproductive function. The following types of surgery may be used:</p> <ul style="list-style-type: disc"> <li>Resection: Surgery to remove tissue or part or all of an organ.</li> <li>Radical inguinal orchiectomy: Surgery to remove one or both testicles through an incision (cut) in the groin.</li> <li>Unilateral salpingo-oophorectomy: Surgery to remove one ovary and one fallopian tube on the same side.</li> </ul> <p>After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy after surgery to kill any cancer cells that are left. Treatment given after surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.</p> <p>Observation</p> <p> Observation is closely monitoring a patient's condition without giving any treatment until signs or symptoms appear or change. For children with extracranial germ cell tumors, this includes physical exams, imaging tests, and tumor marker tests.</p> <p>Chemotherapy</p> <p>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). Systemic chemotherapy is used to treat extracranial germ cell tumors. </p> <p>New types of treatment are being tested in clinical trials. </p> <p>This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied.

Healthy cells, including blood -forming cells, are also destroyed by the cancer treatment. Stem cell transplant is a treatment to replace the blood-forming cells. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the patient completes chemotherapy, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.</p> <p>Radiation therapy</p> <p>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. External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer. External radiation therapy is being studied for the treatment of childhood extracranial germ cell tumors that have come back.</p> <p>Treatment for childhood extracranial germ cell tumors may cause side effects.</p> <p>To learn more about side effects that begin during treatment for cancer, visit <a class="HwLinkExternal" href="https://www.cancer.gov/about-cancer/treatment/side-effects" title="Opens in a new window"><span class="HwLinkText">Side Effects</span></a>.</p> <p> Side effects from cancer treatment that begin after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include the following:</p> <ul style="list-style-type: disc"> <li>Physical problems, such as infertility, trouble hearing and kidney problems.</li> <li>Changes in mood, feelings, thinking, learning, or memory.</li> <li>Second cancers (new types of cancer), such as leukemia or malignant melanoma.</li> </ul> <p>Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. For more information, see Late Effects of Treatment for Childhood Cancer. </p> <p>Patients may want to think about taking part in a clinical trial.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>Patients can enter clinical trials before, during, or after starting their cancer treatment.</p> <p>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.</p> <p>Clinical trials are taking place in many parts of the country.

Some tests that were done to diagnose or stage the cancer may be repeated 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.</p> <p>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 child's condition has changed or if the cancer has recurred (come back). </p> <p>For childhood extracranial germ cell tumors, follow-up may include regular physical exams, tumor marker tests, and imaging tests such as CT scan, MRI or chest x-ray.</p> </div><div class="HwNavigationSection HwSectionVendor" id="sec-ncicdr0000062857-04"><a class="HwSectionNameTag" name="ncicdr0000062857-04" id="anchor-ncicdr0000062857-04" aria-hidden="true"> </a><h2 class="HwSectionTitle">Treatment of Childhood Mature and Immature Teratomas</h2> <p>For information about the treatments listed below, see the Treatment Option Overview section.</p> <p>Treatment of newly diagnosed mature teratomas includes the following:</p> <ul style="list-style-type: disc"> <li>Surgery to remove the tumor followed by observation.</li> </ul> <p>Treatment of newly diagnosed immature teratomas includes the following:</p> <ul style="list-style-type: disc"> <li>Surgery to remove the tumor followed by observation for stage I tumors.</li> <li>Surgery to remove the tumor for stage I–IV tumors.

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 come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in <a class="HwLinkExternal" href="https://www.cancer.gov/espanol/publicaciones/pdq" title="Opens in a new window"><span class="HwLinkText">Spanish</span></a>.</p> <p>PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.</p> <p> <b>Purpose of This Summary</b> </p> <p>This PDQ cancer information summary has current information about the treatment of childhood extracranial germ cell tumors. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.</p> <p> <b>Reviewers and Updates</b> </p> <p>Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change. </p> <p>The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the <a class="HwLinkExternal" href="https://www.cancer.gov/publications/pdq/editorial-boards/pediatric-treatment" title="Opens in a new window"><span class="HwLinkText">PDQ Pediatric Treatment Editorial Board</span></a>. </p> <p> <b>Clinical Trial Information</b> </p> <p>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. </p> <p>Clinical trials can be found online at <a class="HwLinkExternal" href="https://www.cancer.gov/research/participate/clinical-trials" title="Opens in a new window"><span class="HwLinkText">NCI's website</span></a>.
