Health-related Quality of Life in Pediatric Cancer Survivors: A Multifactorial Assessment Including Parental Factors

Aim: We aimed to evaluate the health-related quality of life (HRQOL) and the effect of associated factors such as cancer type, treatment strategies, sex, age, and parental factors like education and psychopathology in pediatric cancer survivors and make a comparison with healthy children. Patients and Methods: “Pediatric Quality of Life Inventory (PedsQL) 4.0 TM, Generic Core Scale” for children and parents, and “Brief Symptom Inventory” for parents were used. Three hundred and two survivors without major mental or motor deficit and 272 healthy controls of 8 to 18 years of age were enrolled to study. Results: Comparison of scores according to child self-report between survivor and control groups revealed lower points in physical and school subscale of survivor group (P<0.01 and P<0.001, respectively). Female survivors had reported significantly worse HRQOL in physical and emotional subscales of PedsQL than male survivors (P<0.001). Female survivors of ≥16 years of age had reported worse scores in school subscale than females of younger age groups and male survivors of same age group. Parents of control group reported better results in school subscales (P<0.001) and social functioning subscales (P<0.05) than parents of survivor group. Brief Symptom Inventory score had significant effect on child self-report and parent proxy-report of physical functioning (P<0.001), emotional functioning (P<0.001), social functioning (P<0.001), and school subscales (P<0.001) of PedsQL. Significantly better scores of physical functioning subscale in the survivors whose parents are university graduate than the survivors whose parents are primary school graduate were detected (P<0.001). The survivors with central nervous system tumors had reported lower scores in the social, emotional, physical, and school functioning subscales of PedsQL than patients with non-Hodgkin and Hodgkin lymphoma (P<0.001). Child self-report school subscale scores were lower in survivors treated with radiotherapy in combination or as sole therapy than survivors in whom radiotherapy was not given (P<0.001). Conclusions: Our study has provided evidence about less-studied determinants of HRQOL like parental factors such as psychopathology or educational level in childhood cancer survivors. Future research can build on this evidence to obtain additional factors other than well-known medical and treatment-related factors.
