Identification of behavioral disorders using the Achenbach questionnaire in children with tumors of the posterior cranial fossa after completion of special treatment (pilot research)

Background. The increase in life expectancy of children who survived cancer leads to new tasks for doctors, psychologists and rehabilitation specialists to assessing the consequences of the experienced disease and its treatment. The most common disorders in children who have survived oncological diseases are behavioral disorders, a decrease in mood background, as well as chronic fatigue.
Aim. To identify predictors of behavioral disorders in children who have survived central nervous system oncological diseases.
Materials and methods. The study involved 52 children with central nervous system tumors aged 6 to 17 years. The median time after completion of therapy in this group of patients was 18 (3–117) months.
Results. As a result of the study, it was shown that such treatment parameters as the degree of tumor malignancy and the radiation therapy volume are associated with behavioral disorders in children who have survived cancer. In such children, a reduced mood background was revealed, and the older the child, the higher the probability of a reduced mood background. A reduced mood background is also associated with the use of vincristine preparation. Children who have a residual tumor are more likely to complain of unpleasant sensations in the body. All children, despite the specifics of their treatment, complain of constant fatigue, which affects their daily activity.
Conclusion. Thus, factors that are associated with behavioral disorders in children who have survived oncological diseases in the central nervous system were identified.
