Factors associated with health-related quality of life in pediatric cancer survivors.

BACKGROUND: Childhood cancer survivors are at risk for late effects of disease and treatment that may be attributed to multiple causes. This study describes health-related quality of life (HRQOL) in childhood cancer survivors and identifies factors related to poor quality of life outcomes. PROCEDURE: Patients age 8-18 years, who attended the long-term information, follow-up, and evaluation (LIFE) clinic at Childrens Hospital Los Angeles during a 1-year time-period were eligible for the study. Eighty-six survivors (mean time off-treatment=7.8 years) completed the Pediatric Quality of Life Inventory 4.0 Generic Core Scales, a LIFE Clinic Intake Questionnaire and rated their fatigue using a 10-point scale. Oncology nurses independently rated subjects' late effects using a 3-point severity scale. Linear regression procedures were used to evaluate the association between demographic and medical factors and HRQOL. RESULTS: Fatigue and more severe late effects were associated with poorer physical functioning (fatigue, P<0.02; late effects, P<0.01). Fatigue, ethnic minority status, and a brain tumor diagnosis were associated with poorer psychosocial functioning (fatigue, P<0.0001; minority status, P<0.04; brain tumor, P<0.01). Fatigue was the only factor related to both poor physical and psychosocial HRQOL. CONCLUSIONS: Long-term follow-up clinics for childhood cancer survivors are in a unique position to monitor HRQOL over time. Factors associated with poorer HRQOL include fatigue, ethnic minority status, a brain tumor diagnosis, and more severe late effects. Future studies need to clarify relationships between ethnicity, socioeconomic status (SES), and HRQOL in cancer survivors.

The PedsQL Brain Tumor Module: initial reliability and validity.

BACKGROUND: Brain tumors (BT) are second only to acute lymphoblastic leukemia as the most prevalent form of pediatric cancer, with BT 5-year survival rates approaching 70%. With increased survival, quality of life has emerged as an essential health outcome. This investigation examines the internal consistency reliability and construct validity of the Pediatric Quality of Life Inventory (PedsQL) Brain Tumor Module. METHODS: The PedsQL 4.0 Generic Core Scales, PedsQL Multidimensional Fatigue Scale, and PedsQL Brain Tumor Module were administered to 99 families. The average age of the 56 boys and 43 girls was 9.76 years (range=2-18 years). The sample included children with tumors located in the posterior fossa/brainstem (N=62, 62.6%), supratentorial (N=15, 15.2%), and midline (N=22, 22.2%). Children were on treatment (N=46, 46.5%), off treatment<12 months (N=19, 19.2%), or off treatment>12 months/long-term survivor (N=34, 34.3%). Treatment included radiation (N=61, 61.6%), surgery (N=83, 83.8%), chemotherapy (N=87, 87.9%), and bone marrow transplant (N=5, 5.1%). RESULTS: Internal consistency reliability was demonstrated for the 24-item PedsQL Brain Tumor Module (average alpha=0.78-0.92, parent proxy-report, n=99; average alpha=0.76-0.87, child self-report, n=51). Construct validity for the PedsQL Brain Tumor Module was supported through an analysis of the intercorrelations with the Generic Core Scales and Fatigue Scale. CONCLUSIONS: The findings provide support for the measurement properties of the PedsQL Brain Tumor Module.

Parent proxy-reported health-related quality of life and fatigue in pediatric patients diagnosed with brain tumors and acute lymphoblastic leukemia.

BACKGROUND: Pediatric patients with brain tumors (BT) are often excluded from health-related quality of life (HRQOL) studies even though they experience more severe disease and treatment-related sequelae than children with other types of cancer. Parent proxy assessments of HRQOL allow for greater inclusion of children who are developmentally immature, physically ill, or cognitively impaired. METHODS: Parents of children ages 2-18 years who were diagnosed at Childrens Hospital Los Angeles and Children's Hospital San Diego with BT (n = 86) or acute lymphoblastic leukemia (ALL; n = 170) evaluated their children's HRQOL over the previous week using the parent-proxy versions of the Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core scales, the PedsQL 3.0 Acute Cancer Module, and the PedsQL Multidimensional Fatigue scales. Multiple regression analyses were used to determine the independent effect of the child's diagnosis on HRQOL. Separate analyses were conducted for patients receiving treatment, patients who had not received treatment for < 12 months, and patients who had not received treatment for > or = 12 months. RESULTS: Patients with BT exhibited more problems than patients with ALL in the physical, social, psychosocial, school, cognitive, and fatigue domains of HRQOL. The Core Physical Health, Core Psychosocial Health, and Fatigue Total scores for patients with BT demonstrated peak improvements for children who had not received treatment for < 12 months and sharp declines for children who had not received treatment for > or = 12 months. The Core Physical Health and Fatigue Total scores for patients with ALL were highest (better HRQOL) for those who had not received treatment for > or = 12 months. CONCLUSIONS: Pediatric patients and survivors of BT experienced more fatigue and HRQOL problems than patients with ALL, and HRQOL differed by treatment status.
