Effects of brain radiotherapy on cognitive performance in adult low-grade glioma patients: A systematic review. Radiother Oncol 2021; 160:202-211. [PMID: 33964327 DOI: 10.1016/j.radonc.2021.04.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 03/18/2021] [Accepted: 04/28/2021] [Indexed: 11/23/2022]
Abstract
Grade II gliomas are slow growing tumours that usually affect younger patients. The mainstream treatment modality at present is surgical. The role of radiation therapy in the management of grade II gliomas has been the subject of considerable debate. Radiation therapy has a proven potential to prolong progression free and overall survival in high-risk patients, but may also produce long-term cognitive deficits. Since grade II glioma patients are expected to live several years, retention of cognitive capacity and quality of life is an equally important endpoint as prolonging progression free survival. Our overarching goal is to critically review the available evidence on the possible neuropsychological effects of postoperative radiotherapy in adult grade II glioma patients. We performed a systematic literature search in Medline, Embase and Cochrane databases up to 1st of May 2020 for studies assessing the cognitive effects of radiation therapy on grade II glioma patients. Eleven studies meeting our inclusion criteria provide either negative or contradictory data regarding the cognitive domains affected, while major confounding variables remain incompletely addressed. The available evidence does not adequately support the notion that current radiation therapy protocols independently produce substantial cognitive decline in grade II glioma patients and therefore it would be premature to argue that radiation associated cognitive morbidity outweighs the benefit of prolonged survival. A large prospective study incorporating a full battery of neuropsychological testing, sufficiently long-term follow-up period and tight control of confounders is due to provide high quality data.

Abstract
Qualitative studies of families with children who have cancer or other serious illnesses have found that families often come to view their child and their lives as normal. They manage illness-related demands using family management styles that sustain usual patterns of family and child functioning. Few studies have addressed the family management styles of families who express less satisfaction with family and child functioning or who are identified by health care professionals as having difficulty with family functioning. Such families are likely to be overrepresented among those whose children are being treated for brain tumors that entail extremely burdensome treatments as well as a range of unfavorable prognoses and long-term sequelae. In fact, little is known about how these families manage on a day-to-day basis and how the interdisciplinary team can best provide supportive care to optimize their functioning. The purpose of this article is to present the Family Management Styles Framework as a tool that is useful in both clinical practice and research for assessing families who have children with cancer, including those with brain tumors.

Abstract
Despite the prevalence of pediatric Central Nervous System (CNS) solid tumors, little is understood about patients' disease-related anxiety experience. Data from 25 remitted pediatric CNS tumor patients posttreatment were collected. Significant symptoms of anxiety were reported by 32% of patients. MRI studies showed all anxious patients had right cortical tumors or left cerebellar tumors. Confound analyses suggest these results are not better accounted for by demographic, disease, or treatment variables. These results evidence the risk some pediatric neuro-oncologic patients face for developing significant anxiety symptoms.

Abstract
The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N = 18) and third ventricle tumors (N = 24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2-5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits.

Abstract
Research into depression in paediatric cancer is in its early stages, but nevertheless has presented interesting challenges regarding the recognition and measurement of depression in a medically ill population. In this article we discuss the complex interaction between physical and psychological variables, and the diagnostic difficulties arising from this. We review the epidemiological findings regarding prevalence, evaluating the apparently low prevalence rate in the light of methodological weaknesses. Hypotheses put forward to explain the findings are discussed. We conclude by highlighting areas for future research.

Abstract
Zusammenfassung. In diesem Beitrag wird ein Überblick über die kognitiven, behavioralen und psychosozialen Langzeitfolgen bei Kindern und Jugendlichen mit Hirntumoren gegeben. In der Übersicht wird deutlich, daß die kognitiven Leistungen der pädiatrischen Hirntumor-Patienten (insb. nach Radiatio) deutlich stärker beeinträchtigt sind als bei Kindern mit Leukämieerkrankung nach ZNS-Bestrahlung. Verbunden damit, aber auch aufgrund der großen Häufigkeit von Verhaltensauffälligkeiten, wird die schulische Reintegration als schwierig beschrieben. Die massiven kognitiven Beeinträchtigungen und Verhaltensauffälligkeiten der Hirntumor-Kinder machen die Notwendigkeit der Konzeption und Evaluation von Rehabilitations- und Beratungsmaßnahmen für die betroffenen Kinder und ihre Eltern deutlich.

Abstract
BACKGROUND Cognitive deficits are the hallmark of dose limiting late radiation morbidity in the CNS. Little is known about the neuropsychometric morbidity of treatment in adults with primary brain tumours. We set out to evaluate systematically the neuropsychometric function of all long-term survivors in order to document the frequency and severity of impairment and study its relationship with tumour and treatment related parameters. MATERIALS AND METHODS 30 patients surviving in clinical and radiological remission for > 4 years following irradiation were recalled for clinical examination, CT/MRI scan and neuropsychometric testing. The 14 males, 16 females, (mean age 42.5 years), represented all but one long term survivors treated with radiotherapy in the Department of Clinical Oncology between 1971 and 1990. Twenty-five patients had a histological diagnosis of glioma. Patients treated before 1987 (n = 16) received whole brain irradiation (WBI); focused irradiation (FI) has been used since (n = 14). RESULTS The two groups were similar were in age, initial tumour type and surgical treatment, but the WBI group showed more evidence of neuropsychometric impairment than the FI group with significantly lower group median scores in tests of visuospatial organisation (WAIS Block Design, P = 0.01), visual memory (Rey Complex figure, P = 0.003) and complex information processing (Trails A, P = 0.003; Trails B, P = 0.002). Pre-morbid IQ estimated from sociodemographic variables, was comparable in the 2 groups which were not significantly different in their emotional state as assessed by the HADS. On univariate analysis radiation volume (P = 0.05) and time from treatment (P = 0.02) were the main factors associated with neuropsychometric deficit. Multivariate analysis by logistic regression confirmed WBI as the only independent predictor of neuropsychometric impairment (WBI vs. FI, odds ratio = 7.1, 95% C.I. 1.2-42.3, P = 0.03). CONCLUSIONS Neuropsychometric deficits are common and can be related to time from treatment and radiation technique. Neuropsychometric testing can be a useful tool in the evaluation of different treatment strategies.

Abstract
This paper provides an overview of pediatric brain tumors and reviews the literature on long-term neurobehavioral outcomes for these children. Progress in this area has been slow due to numerous methodological and practical complications. While some general conclusions can be drawn, the development of comprehensive models awaits more research into the multiplicity of biological and nonbiological events, and their interactions, potentially affecting outcome. Increased theoretical and methodological sophistication will be needed to address this complex classification of diseases. Barriers to research in this area are enumerated as are suggestions for future efforts.

Abstract
Gliomas that arise in the brain stem have been associated with a poor prognosis. Diagnostic neuroimaging readily identifies the tumor as it extends between normal brainstem structures. Histologic sampling of tumor with stereotactic methods is notoriously unreliable in establishing a definitive prognosis. Clinical trials that incorporate high-dose chemotherapy, autologous bone marrow rescue, and irradiation hold promise of better tumor control by overcoming the inaccessibility of the central nervous system to standard doses of chemotherapy. We review the pathology, clinical features, neuroimaging features, and current therapeutic concepts relative to brainstem glioma. The pediatric neurologist has a pivotal role in identifying and monitoring children with this malignancy.

Abstract
The literature on the neuropsychological status of children with primary brain tumors was reviewed to identify English-language publications reporting the results of standardized, quantitative measures of patient function. The 22 studies that met these review criteria, representing 544 patients, were evaluated to assess the relationship between traditional risk factors (age at diagnosis, tumor location, radiation therapy, and time since completion of treatment), as well as subsequent intellectual development, academic achievement, psychosocial adjustment, and neuropsychological status. The impact of other potentially salient factors, such as seizures and sensory and motor deficits, was evaluated when possible. Despite inconsistent reporting of demographic and treatment-related effects across studies which precluded formal meta-analysis, we were able to confirm the primary importance of radiation therapy volume and age at treatment on IQ. No effects were detected for tumor location. Younger children treated with cranial (whole brain) irradiation showed a 14-point deficit in IQ as compared with their older counterparts. No significant differences were noted between older children receiving local or cranial irradiation, although both groups had IQ levels 12-14 points lower than those not irradiated. The high-risk groups identified in this study require increased clinical surveillance. Definitive evaluation of potential risk factors for neuropsychological impairment will depend on more complete reporting of relevant patient characteristics and interinstitutional studies.

Abstract
A major thrust in research in psychosocial oncology is the study of the interaction of psychologic and physiologic variables. This discussion reviews the current status and future directions of such research. Areas addressed include pain, nausea and vomiting with chemotherapy, sexuality, effects of cancer on psychologic and neuropsychologic function, impact of psychologic factors on cancer and its treatment, and psychoneuroimmunology. In addition, specific recommendations for strategies to facilitate research in these areas of psychosocial oncology are proposed.

Abstract
In an unselected series of pediatric brain tumors, 56 of 60 long-term survivors--craniopharyngiomas and pituitary tumors excluded--were investigated and interviewed mean X = 10 (5-16) years after diagnosis. After this time, sequelae were stable and included cognitive (38%), motor (25%), visual (20%), hormonal (20%), and psychological-emotional (14%) dysfunction. Memory dysfunction was found in 22% of patients with normal intelligence. Moderate or severe disability, from combinations of these impairments, was found in 34%. Sixty-six percent had no or mild disability compatible with active life and employment. However, these patients less often were married or had children compared with a control group of healthy subjects. Moderate and severe disability was found in 48% of supra- and in 21% of infratentorial tumors, after radiotherapy (RT) in 55% vs. without RT in 18%. RT before 6 years of age caused subnormal IQ in all cases. The self-reported quality of life was not related to degree of disability. Patients with psychological-emotional sequelae self-evaluated their quality of life lower than did patients with other types of long-term sequelae.

Abstract
The number of studies documenting the long-term morbidity of CNS treatment has increased dramatically in recent years. Cranial irradiation, in particular, has been associated with cognitive deficits and neuroanatomic pathology. Children who are treated at an early age and individuals who receive higher doses (2,400 cGy or greater) appear to be at greatest risk for these sequelae. Much more research on the pathogenesis of delayed injury following CNS treatment is needed. Although several compelling mechanisms have been proposed, little empirical evidence is available. This knowledge is essential to the identification of agents that may protect normal brain tissue from injury. Even less is known about the effects of age at time of treatment, type of treatment (radiation v chemotherapy), or dose of radiation in relation to delayed injury. Of utmost importance are studies that will establish the predictive relationship between brain injury and cognitive deficits. This would allow clinicians to predict patients who are at risk for cognitive impairment in order to institute appropriate preventive or remedial interventions.

Abstract
Seven school-aged children treated for temporal lobe astrocytomas with surgical resection and irradiation were prospectively tested to evaluate their intellectual, academic, personality, and neurologic status after therapy. At their most recent follow-up examination, neuropsychologic functioning was adequate in only two patients. The other five children manifested either intellectual deterioration, learning disability, mental retardation, or psychopathology. These deficits were associated with poor postoperative performance status, inadequate seizure control, tumor recurrence, and younger age at diagnosis. No pattern of intellectual, academic, or personality dysfunction emerged in association with left- versus right-hemisphere tumors.

Abstract
Surgery and radiotherapy are the primary modalities of treatment for pediatric brain tumors. Despite the widespread use of these treatments, little is known of their acute effects (within one year posttreatment) on neuropsychological functions. An understanding of acute treatment effects may provide valuable feedback to neurosurgeons and a baseline against which delayed sequelae may be evaluated. This study compares pre- and posttherapy neuropsychological test performance of pediatric brain tumor patients categorized into two groups on the basis of treatment modalities: surgery (n = 7) and radiotherapy (n = 7). Treatment groups were composed of children aged 56 to 196 months at the time of evaluation with heterogeneous tumor diagnoses and locations. Comparisons of pretherapy findings with normative values using confidence intervals indicated that both groups performed within the average range on most measures. Outstanding deficits at baseline were observed on tests of fine-motor, psychomotor, and timed language skills, and are likely to be attributable to tumor-related effects. Comparisons of pre- versus posttherapy neuropsychological test findings indicated no significant interval changes for either group. Results suggest that surgery and radiotherapy are not associated with acute effects on neuropsychological functions.

Abstract
Twenty-six children with primary brain tumors were studied prospectively with regard to their sensorimotor, intellectual, academic, and emotional status. Serial evaluations were conducted after surgery (pre-irradiation) and six months after the completion of radiation therapy. The timing of the second evaluation was chosen so as to antedate the late effects of irradiation. Children over 6 years old displayed significant improvement of intellectual function over time, with only 11% exhibiting deterioration on one or more cognitive parameters. In contrast, 68% of younger children clinically deteriorated in one or more areas of intellectual functioning, with prominent difficulties in memory and selective attention for age. Children under 6 years old with supratentorial tumors were less likely than those with posterior fossa tumors to improve their cognitive performance. At the second evaluation, 23% of the patients were functioning below normal (IQ less than 80) intellectually, with 50% of the younger children and 11% of the older children receiving special educational assistance. Approximately 40-50% of the patients manifested emotional adjustment problems at each evaluation. The results are discussed in terms of the clinical need to follow similar patient populations with formal psychological assessments over time, and in terms of the difficulties involved in defining factors that determine the functional status of children surviving brain tumors.
