Learn about atypical teratoid/rhabdoid tumor (AT/RT) grades, features, causes, symptoms, who the tumors affect, how and where they form, and treatments.
An atypical teratoid rhabdoid tumor (AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS), including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum).
Dec 15, 2023 · Central nervous system (CNS) atypical teratoid/rhabdoid tumor (AT/RT) is a very rare, fast-growing tumor that begins in the brain and spinal cord. It usually occurs in children aged 3 years and younger, although it can occur in older children and adults.
Dec 27, 2023 · Atypical teratoid rhabdoid tumor (ATRT) is a fast-growing cancerous tumor of the central nervous system that mostly affects young children. Radiation oncologist Susan McGovern, M.D., Ph.D., shares insights about this rare brain tumor and its treatment.
Atypical teratoid rhabdoid tumor (ATRT) is a rare, often lethal brain tumor of childhood characterized by a complex epigenetic landscape amongst a simple genetic background. Recent molecular studies have defined key biologic events that contribute to tumorigenesis and molecular subtypes of ATRT.
Oct 5, 2018 · Atypical teratoid/rhabdoid tumor (AT/RT) is a rare CNS cancer that typically occurs in children younger than 3 years of age. Histologically, AT/RTs are embryonal tumors that contain a rhabdoid component as well as areas with primitive neuroectodermal, mesenchymal, and epithelial features.
Sep 12, 2012 · Atypical teratoid rhabdoid tumors (ATRTs) are rare central nervous system tumors that comprise approximately 1–2% of all pediatric brain tumors; however, in patients less than 3 years of age this tumor accounts for up to 20% of cases.
An atypical teratoid rhabdoid tumor (ATRT) is a very rare, aggressive tumor of the central nervous system, occurring mostly in the cerebellum, the part of the brain that controls movement and balance, or the brain stem, the part of the brain that controls basic body functions.
Atypical teratoid/rhabdoid tumors are rare tumors that grow very quickly within the brain and/or spinal cord. They are found most frequently in children ages 3 and younger. These tumors commonly arise when a child has a genetic mutation within one of two tumor-suppressor genes—SMARCB1 or SMARCA4.
Atypical teratoid rhabdoid tumors (ATRT) are rare, aggressive tumors of the central nervous system. They occur primarily in the cerebellum (the part of the brain that controls movement and balance) and the brain stem (the part of the brain that controls basic body functions).
