Executive and Socio-cognitive Functions in Survivors of Primary Brain Tumor: Impact on Patients' Quality of Life

Not Applicable

• Conditions: Quality of Life; Primary Brain Tumor; Neurocognition

• Registration Number: NCT02693405
• Lead Sponsor: University Hospital, Angers

Brief Summary

Significant advances in primary malignant brain tumors (PBT) treatment have led to dramatically improved survival, both in children and adults. However, survival has not come without a cost and aggressive treatment methods associated with significant long-term adverse effects, often referred to as "late effects" (Panigrahy \& Blüml, 2009). These effects are the medical, physical, cognitive and psychosocial sequelae associated with cancer and its treatments that generally emerge two to five years after treatment ends (e.g., Landier \& Bhatia, 2008).

The most serious challenge survivors of brain tumors face may be cognitive dysfunction. One especially important cognitive domain is executive functioning, which refers to essential factors such as problem-solving, goal-directed behavior and the ability to maintain stable interpersonal relationships (Lezak et al., 2004). Despite the potential impact of executive impairments on behavioral regulation and quality of life, few studies were conducted with survivors of PBT specifically for the assessment of executive functioning. Another fundamental neuro-cognitive domain is social cognition, which refers to the ability to understand the intentions and beliefs of others (Frith \& Singer, 2008). Social cognitive deficits are expected to impair autonomy and relationships, but scarce attention has been devoted to the study of social cognition in survivors of PBT and no study has attempted to compare socio-cognitive data and measures of health-related quality of life. It is noteworthy that executive function and socio-cognitive skills improve throughout childhood and adolescence, and improvements in these skills have frequently been attributed to maturation of the brain, especially the prefrontal cortex (e.g., Tamnes et al., 2010). This suggests a greater impact of the disease and its treatment on these functions in children/adolescents.

Detailed Description

First, the investigators will calculate the prevalence of cognitive and socio-cognitive deficits, by comparing the performances of patients (children/adolescents and adults) to normative data available for each tasks and to performances of healthy controls matched on socio-demographic criteria.

Second, the investigators will compare the neuropsychological scores for cognitive and socio-cognitive tasks to health related quality of life (HRQOL) data (composite scores and by domains). Comparisons of neuropsychological and HRQOL scores will be performed between the two populations (children / adolescents and adults).

Third, the investigators will compare the data from the two age groups for the aforementioned variables (cognitive and behavioral executive assessments, cognitive and affective TOM). The proximity of the tasks should provide valid elements of comparison. The investigators will compare the questionnaires in auto-and hetero-evaluation for each HRQOL scales, and also for executive behavioral questionnaires.

Finally, to evaluate the investigators will compare the HRQOL patients/relatives' data to measure the potential impact of the disease on HRQOL of relatives of PBT survivors and the potential link between these data.

Primary Outcome Measures

Name	Time	Method
performances in executive tasks and executive questionnaires	2 years	Executive functions will be assessed using executive cognitive tasks (Stroop task for inhibition, Modified Card Sorting Task for mental flexibility, Digit spans for working memory) and questionnaires (BRIEF for childrens and BRIEF-A for adults) for executive behavioral measures.; Standardized norms in French are available for these tasks, which permit determining if the performances are pathological. So, these multiple measurements will be aggregated to determine the number of patients with pathological performances for executive tasks (tasks and questionaires).
performances in social cognition tasks	2 years	The first task involves a mental representation or belief about the state of the world (eg, Samson, 2012). The items offered in this kind of task are used to assess the ability to understand that the belief to infer in a type of scenario does not correspond to the reality.; The second task will be the Faux Pas task (Stone et al., 1998). This task is composed of written scenarios and the subject must detect if someone has done or said something he should not have said- the "faux pas". If the subject detects that there was a faux pas, additional questions are asked to detect whether he/she understands the cognitive side and the emotional side of the faux pas.; Standardized norms in French are available for these tasks, which permit determining if the performances are pathological. These multiple measurements will be aggregated to determine the number of patients with pathological performances.

Secondary Outcome Measures

Name	Time	Method
quality of life questionnaires	2 years	Health-related quality of life (HRQOL) will be assessed in adults with the French validated version of the 36-Item Short Form Survey (SF-36; Ware \& Sherbourne 1992) and a specific questionnaire for assessing quality of life of patients with brain tumors (QLQ-C30-BN20), commonly used in the international literature (eg, Chen et al, 2012;. Pulenzas et al, 2014).; Regarding the HRQOL assessment in children, the choice fell on the Peds-Ql. The PEDS QL measures HRQOL with three major composite assessments -psychosocial, physical, and total HRQOL.; Standardized norms in French are available for questionaires, which permit determining if the performances are pathological. These measurements will be aggregated to determine the number of patients with abnormal performances for these questionaires.
