Neuroblastoma Screening (PDQ®): Screening - Health Professional Information [NCI] - Evidence of Benefit
Evidence of screening effect derives from descriptive studies of local and national programs in Japan, uncontrolled pilot experiences at a number of sites in Europe and the United States, and population-based studies in Canada and Germany.[1,2,3,4,5,6,7]An increase in survival rates among screen-detected cases would be expected if screening was detecting neuroblastoma at an earlier and more curable stage. While improved survival rates after initiation of screening have been reported,[8,9] these observations should be viewed cautiously because improvements could be caused by lead-time bias, length bias, and identification of cases through screening that would have spontaneously regressed. Screening results in an increased incidence of early-stage disease. The cases detected by screening almost exclusively have biologically favorable properties (unamplified N-myc oncogene, near triploidy, and favorable histology), and this type of favorable neuroblastoma has a high
Childhood Astrocytomas Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview for Childhood Astrocytomas
Many of the improvements in survival in childhood cancer have been made as a result of clinical trials that have attempted to improve on the best available, accepted therapy. Clinical trials in pediatrics are designed to compare new therapy with therapy that is currently accepted as standard. This comparison may be done in a randomized study of two treatment arms or by evaluating a single new treatment and comparing the results with those that were previously obtained with existing therapy.Because of the relative rarity of cancer in children, all patients with brain tumors should be considered for entry into a clinical trial. To determine and implement optimum treatment, treatment planning by a multidisciplinary team of cancer specialists who have experience treating childhood brain tumors is required. Radiation therapy of pediatric brain tumors is technically very demanding and should be carried out in centers that have experience in that area in order to ensure optimal
Childhood Ependymoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Recurrent Childhood Ependymoma
Recurrent childhood ependymoma is a tumor that has recurred (come back) after it has been treated. Childhood ependymoma commonly recurs, usually at the original cancer site. The tumor may come back as long as 15 years or more after initial treatment.

Adult Brain Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Adult Brain Tumors
Incidence and MortalityNote: Estimated new cases and deaths from brain and other nervous system tumors in the United States in 2013:New cases: 23,130.Deaths: 14,080.Brain tumors account for 85% to 90% of all primary central nervous system (CNS) tumors. Available registry data from the Surveillance, Epidemiology, and End Results (SEER) database for 2007 indicate that the combined incidence of primary invasive CNS tumors in the United States is 6.36 per 100,000 persons per year with an estimated mortality of 4.22 per 100,000 persons per year. Worldwide, approximately 238,000 new cases of brain and other CNS tumors were diagnosed in the year 2008, with an estimated 175,000 deaths. In general, the incidence of primary brain tumors is higher in whites than in blacks, and mortality is higher in males than in females.Few definitive observations on environmental or occupational causes of primary CNS tumors have been made. Exposure to vinyl chloride may predispose to the

Pituitary Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview
The goals of treatment of pituitary adenomas include normalization of hormonal secretion (i.e., normalization of hypersecretion and improvement in hypofunction) and resolution or cessation of the progression of neurological defects. Standard treatments for patients with pituitary tumors include:Surgery.Radiation therapy.Medical therapy.A combination of surgery, radiation therapy, and medical therapy.The treatment of choice must be individualized and is dictated by the type of tumor, the nature of the excessive hormonal expression, and whether or not the tumor extends into the brain around the pituitary.[1,2]The transsphenoidal microsurgical approach to a pituitary lesion is the most widely employed surgical approach to pituitary lesions and represents a major development in the safe surgical treatment of both hormonally active and nonfunctioning tumors.[3,4,5] This approach is often successful in debulking tumors, even those that have a significant suprasellar extension.

Adult Brain Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
There are different types of treatment for patients with adult brain and spinal cord tumors. Different types of treatment are available for patients with adult brain and spinal cord 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.Four types of standard treatment are used:Watchful waitingWatchful waiting is closely monitoring a patient's condition without giving any treatment until symptoms appear or change.Surgery Surgery may be used to diagnose and treat adult brain and spinal cord tumors.
