Cognitive Function After Radiation Therapy for Brain Tumours

2019-10-15 11:11:34 | BioPortfolio


This study will assess cognitive function in adult patients with a primary brain tumour treated with surgical resection with or without radiation therapy (RT). All types of brain tumours apart from glioblastoma will be included


RT to brain tumours causes cognitive dysfunction. The extent of RT induced changes in cognitive function and radio-sensitivity of the brain is unknown. RT with protons instead of photons spares the healthy brain tissue more and is believed to reduce the risk of cognitive dysfunction. There is modest knowledge on which parts of the brain the investigators need to spare, to prevent cognitive dysfunction.

The study is a cross sectional study assessing cognitive function in patients with brain tumours previously treated with RT compared to a similar non irradiated group. 104 patients with specified brain tumours from Aarhus University Hospital treated in the period 2006-2016 will be included. The patients will do patient reported outcome (PRO) and undergo neuropsychological assessment with standardized tests: They will do this prior to RT treatment and ½, 1, 3 and 5 years afterwards. The PRO's included measures on quality of life, fatigue, sleep, depression, anxiety, and socio demografica. The standardized tests are: Trail making Test (TMT); Hopkins Verbal Learning Test (HVLT); Controlled Oral Word Association Test (COWAT) - Animals and S; Coding and Digit Span from WAIS-IV; Paced Auditory Serial Addition Test (PASAT). The correlation between cognitive scores and RT dose-volume parameters to specific areas in the brain will be tested.

Medical and Biotech [MESH] Definitions

A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE. (From Brain 1998 Jan;121(Pt 1):115-26)

Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.

A cytologic technique for measuring the functional capacity of tumor stem cells by assaying their activity. It is used primarily for the in vitro testing of antineoplastic agents.

A direct form of psychotherapy based on the interpretation of situations (cognitive structure of experiences) that determine how an individual feels and behaves. It is based on the premise that cognition, the process of acquiring knowledge and forming beliefs, is a primary determinant of mood and behavior. The therapy uses behavioral and verbal techniques to identify and correct negative thinking that is at the root of the aberrant behavior.

Benign and malignant intra-axial tumors of the MESENCEPHALON; PONS; or MEDULLA OBLONGATA of the BRAIN STEM. Primary and metastatic neoplasms may occur in this location. Clinical features include ATAXIA, cranial neuropathies (see CRANIAL NERVE DISEASES), NAUSEA, hemiparesis (see HEMIPLEGIA), and quadriparesis. Primary brain stem neoplasms are more frequent in children. Histologic subtypes include GLIOMA; HEMANGIOBLASTOMA; GANGLIOGLIOMA; and EPENDYMOMA.
