  1. Osteosarcoma and Malignant Fibrous Histiocytoma of Bone Treatment (PDQ®): Treatment - Patient Information [NCI] - About This PDQ Summary

    About PDQPhysician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. 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 Spanish.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.Purpose of This SummaryThis PDQ cancer information summary has current

  2. Stage Information

    There is no generally applied staging system for childhood brain stem gliomas.[1] It is uncommon for these tumors to have spread outside the brain stem itself at the time of initial diagnosis. Spread of malignant brain stem tumors is usually contiguous; metastasis via the subarachnoid space has been reported in up to 30% of cases diagnosed antemortem.[2] Such dissemination may occur prior to local relapse but usually occurs simultaneously with or after local disease relapse.[3]The less common tumors of the midbrain, especially in the tectal plate region, have been viewed separately from those of the brain stem because they are more likely to be low grade and have a greater likelihood of long-term survival (approximately 80% 5-year progression-free survival vs. <10% for tumors of the pons).[1,4,5,6,7,8] Similarly, dorsally exophytic and cervicomedullary tumors are generally low grade and have a relatively favorable prognosis. Children younger than 3 years may have a more favorable

  3. Late Effects of Treatment for Childhood Cancer (PDQ®): Treatment - Patient Information [NCI] - Digestive System

    Teeth and jawsProblems with the teeth and jaws are late effects that are more likely to occur after treatment for certain childhood cancers.Treatment for these and other childhood cancers may cause the late effect of problems with teeth and jaws:Head and neck cancers.Hodgkin lymphoma.Leukemia that has spread to the brain and spinal cord.Nasopharyngeal cancer.Neuroblastoma.Radiation to the head and neck and certain chemotherapy drugs increase the risk of late effects to the teeth and jaws.The risk of health problems that affect the teeth and jaws increases after treatment with the following:Radiation therapy to the head and neck.Total-body irradiation (TBI) or chemotherapy with busulfan as part of a stem cell transplant.Chemotherapy with higher doses of alkylating agents such as cyclophosphamide.Risk may also be increased in survivors who were younger than 5 years at the time of treatment because their permanent teeth had not fully formed. Late effects that affect the teeth and jaws

  5. Cancer Prevention Overview (PDQ®): Prevention - Patient Information [NCI] - Risk Factors

    Scientists study risk factors and protective factors to find ways to prevent new cancers from starting. Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective factor.Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Risk factors that a person can control are called modifiable risk factors.Many other factors in our environment, diet, and lifestyle may cause or prevent cancer. This summary reviews only the major cancer risk factors and protective factors that can be controlled or changed to reduce the risk of cancer. Risk factors that are not described in the summary include certain sexual behaviors, the use of estrogen, and being exposed to certain substances at work or to certain chemicals.Factors That are Known to Increase

  6. Childhood Central Nervous System Germ Cell Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Options for Childhood Central Nervous System Germ Cell Tumors

    Newly Diagnosed GerminomasTreatment may include the following:Radiation therapy to the tumor and ventricles (fluid -filled spaces) of the brain. A higher dose of radiation is given to the tumor than the area around the tumor.Chemotherapy followed by radiation therapy.A clinical trial of chemotherapy followed by radiation therapy given in lower doses depending on the patient's response.Newly Diagnosed TeratomasTreatment may include the following:Surgery to remove as much of the tumor as possible. Radiation therapy and/or chemotherapy may be given if some of the tumor remains.Newly Diagnosed NongerminomasTreatment of choriocarcinoma, embryonal carcinoma, yolk sac tumor, or mixed germ cell tumor may include the following:Chemotherapy followed by radiation therapy.High-dose chemotherapy with stem cell rescue using the patient's own stem cells.A clinical trial of chemotherapy followed by radiation therapy given in lower doses depending on the patient's response.Sometimes the tumor marker

  7. Childhood Astrocytomas Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

    There are different types of treatment for patients with childhood astrocytoma.Different types of treatment are available for children with astrocytomas. 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. 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.Children with astrocytomas should have their treatment planned by a team of health care providers who are experts in treating childhood brain tumors. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric

  10. Genetics of Colorectal Cancer (PDQ®): Genetics - Health Professional Information [NCI] - Colon Cancer Genes

    Major GenesMajor genes are defined as those that are necessary and sufficient for disease causation, with important mutations (e.g., nonsense, missense, frameshift) of the gene as causal mechanisms. Major genes are typically considered those that are involved in single-gene disorders, and the diseases caused by major genes are often relatively rare. Most pathogenic mutations in major genes lead to a very high risk of disease, and environmental contributions are often difficult to recognize.[1] Historically, most major colon cancer susceptibility genes have been identified by linkage analysis using high-risk families; thus, these criteria were fulfilled by definition, as a consequence of the study design. The functions of the major colon cancer genes have been reasonably well characterized over the past decade. Three proposed classes of colon cancer genes are tumor suppressor genes, oncogenes, and DNA repair
