Abstract
BackgroundThis study aims at determining the health-related quality of life (HRQOL) of children with acute lymphoblastic leukemia (ALL) after the induction therapy, assessing the agreement between child self-reports and family proxy-reports HRQOL, and determining the factors related to this agreement, especially child age, family attendance, and children’s social relationships beyond the family.MethodsWe analyzed questionnaire data (2012–2017) from the Japanese Pediatric Leukemia/Lymphoma Study Group’s clinical study (ALL-B12). Participants were children with B-cell precursor ALL aged 5–18 and their family members, who mostly took care of the child during hospitalization. Participants answered the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales (PedsQL-G), and Cancer Module (PedsQL-C) to measure pediatric HRQOL. We calculated the differences between child self-reported and family proxy-reported subscale scores along with intraclass correlation coefficients (ICC). We conducted multiple regression analyses according to all participant pairs and age groups (young children, school age, and adolescents), with ICCs for all PedsQL-G subscales (ICC-G) and all PedsQL-C subscales (ICC-C) as the outcome variables.ResultsFive hundred twenty-two pairs of children and their families were analyzed. We observed a moderate level of agreement on most PedsQL subscales between child self-reports and family proxy-reports; however, worry had the weakest agreement for all PedsQL subscales (ICC = .32, 95% confidence interval = .24–.40). The agreement of ICC-C was positively related to family attendance in the hospitalization, only for the young children group (B = .185, p = .003).ConclusionsWe observed some differences between child self-reports and family proxy-reports of HRQOL of children with ALL. Both child self-reports and family proxy-reports captured HRQOL in the induction therapy. We suggest that attending to young children’s hospitalization affects the level of agreement between reports on their HRQOL.

Summary
This study aims at determining the health-related quality of life (HRQOL) of children with acute lymphoblastic leukemia (ALL) after the induction therapy, assessing the agreement between child self-reports and family proxy-reports HRQOL, and determining the factors related to this agreement, especially child age, family attendance, and children’s social relationships beyond the family. With the rise of the survival rate, researchers conducting clinical trials have increasingly valued determining time-to-event outcomes, such as overall and disease-free survival rate, as well as patients’ subjective outcomes, such as the quality of life, which directly affected to the extent that they experience to receive treatment and undergo painful procedures [6]. The scales for assessing HRQOL are generally divided into two types. First are “generic scales,” focused on children’s general health condition regardless of the presence of a specific disease or disorder. Disease-specific scales are able to precisely pinpoint the effects of a given disease on children’s health and functioning [10, 11]
