The incidence of cancer in children in Uruguay is similar to that in industrialized societies but the survival rate is half as great. This study assesses another important measure of treatment effectiveness: the health‐related quality of life (HRQL) of survivors.
All new patients diagnosed in a 3‐year period were eligible if free of disease for at least 2 years after therapy and at least 7 years of age at the time of study. A sample of convenient subjects for comparison was obtained from schools and clinics for well children. During a 7‐month period, Spanish language interviewer‐administered questionnaires were used to collect Health Utilities Index data from survivors and the comparison group (self‐reports), and from proxies (parents, physicians, and teachers).
Of 113 eligible survivors, 95 (84%) participated together with 96 “control” subjects. Control subjects have a higher mean HRQL utility score than survivors (
P< 0.001). The mean score for survivors of acute lymphoblastic leukemia (ALL): 0.72 (n = 49) is higher than the score for survivors of brain tumors: 0.60 (n = 20), as expected. Inter‐rater agreement is highest between survivors and parents, and lowest between controls and physicians or teachers. Conclusions
The burden of morbidity in survivors of childhood cancer in Uruguay is considerable and greater than that in a comparative group of healthy children. Survivors of ALL have better HRQL than survivors of brain tumors, mirroring experience elsewhere. The level of inter‐rater agreement is related to the degree of familiarity of the pair‐members of respondents with each other. Pediatr Blood Cancer 2008;50:838–843. © 2007 Wiley‐Liss, Inc.
