a classification that accounts for appx 50% of pediatric brain tumors with the etiology of pediatric cancers unknown
causative factors include genetic predisposition, environmental influence, radiation and toxin exposure, and association with certain childhood disorders
What are the two types of atrocytoma?
cerebellar and supratentorial
characteristics of this type of astrocytoma include clumsiness, ataxic gait, headache, change in personality, and vomiting
characteristics of this type of astrocytoma include headache, seizures, change in personality, visual impairments, and vomiting
treatment for this type of astrocytoma consists of surgical resection with an 80 - 90% cure rate
treatment for this type of astrocytoma requires surgery to resect the tumor with radiation and/or chemotherapy
a cancer of hte blood that occurs when leukocytes change into malignant cells. These immature cells proliferate, accumulate in bone marrow, and ultimately cease th production of normal cells. This process will spread to lymph nodes, liver, spleen, and other areas of the body
causative factors include evnironmental, chemical or toxin exposure, genetic predisposition, and viral association.
characteristics of these types include an abrput onset with high fever, bleeding, enlarged lymph nodes and spleen, progressive weakness, fatigue, and painful joints. blood work will indicate anemia, leukocyte count and thrombocytopenia
treatment will vary based on the type and degree; options include immunotherapy, cytotoxic agents, chemotherapy or radiation and bone marrow transplant
a tumor that initiates from primitive ectodermal cells of the neural late and is found within the sympathetic nervous system, primarily seen in the adrenal glands or paraspinal ganglions. this is the most common malignant tumor seen in children
the causative factors include gentic predisposition, familial incidence, enviornmental influence, radiation and toxin exposure or viral association
characteristics vary with the site and include an abdominal mass, change in personality, anemia, sweating, pain, and diarrhea
treatment includes surgical resection, chemotherapy, and radiation. prognosis is best for children diagnosed in the first year of life.
a cancer of the hymphatic system with peak incidence between 7 - 10 years with the causative facor being a viral infection
characteristics can differ from adults and include abdominal pain, swallowing issues, anemia, and swelling. nodular histologies are rare in children
treatment is based of the site/textent of the cancer and includes surgery, chemotherapy, and radiation
a cancer that occurs at the epiphyses of long bones and is the most common form of bone cancer in children with a peak incidence between the ages of 10 - 20
causative factors are unknown, however, there is a correlation between immunoincompetence and rate of tumor progression and can metastasize quickly
characteristics include presence of a mass, rapid metastases, and associated pain. diagnosis can be made with a biopsy
treatment includes amputation with proximal resection to ensure proper removal of affected tissue or surgical procedures that attempt to resect the tumor and salvage the limb. Chemotherapy is beneficial, however, radiation is not effective with this type of tumor
an embryonal adenomyosarcoma found in the kidney. most cases are diagnosed between one and four years of age
causative factors include genetic inheritance as an autosomal dominant disease or a non-inherited form with an unknown etiology
characteristics include an abdominal mass, pain, hematuria, fever, nausea, and vomiting
treatment includes resection of the kidney and the associated lymphatic tissue followed by chemotherapy and/or radiation. dactinomycin is also administered due to the drug's antitumor properties.
