BackgroundCompleting therapy is one of the major transitions in care in the practice of pediatric oncology and, therefore, deserves special consideration. The purpose of the study was to investigate healthârelated quality of life (HRQOL) of pediatric patients, and emotional reactions of their parents, shortly after the end of successful treatment.MethodsHRQOL of 126 patients, aged 1â15 years, on average 2 months after the end of successful treatment, was assessed with the TNOâAZL Preâschool Quality of life Questionnaire and the TNOâAZL Children's Quality of life Questionnaire. Emotional adjustment of 124 mothers and 111 fathers was assessed with the General Health Questionnaire and the Situation Specific Emotional Reaction Questionnaire. The outcomes of the patients and parents were compared with norm data by means of one sample tâtests, one sample signâtests or binomial tests.ResultsAll age groups, except patients aged 8â11 years, experienced worse HRQOL than the norm with respect to motor functioning. In addition, preâschool patients were rated worse on sleeping, appetite, stomach, skin, problem behavior, anxiety, and liveliness, and patients aged 6â7 years on autonomy and cognitive functioning. Parents reported more psychological distress than the norm. Compared to parents whose children were 1â5 years after cancer treatment, they suffered more from feelings of loneliness, helplessness, and uncertainty.ConclusionsA few months after the end of successful cancer treatment, both patients and parents appeared to experience worse wellâbeing than the norm to a clinically relevant extent. Supporting patients and parents should not stop when treatment ends. Pediatr Blood Cancer 2006;47:312â319. © 2005 WileyâLiss, Inc.
