Popis: Purpose The purpose of this study was to analyze the effect of hospital care volume on the overall survival of children with cancer in Southern Brazil. Patients and methods We performed a retrospective cohort study of 1378 cancer patients aged 0-19 years, diagnosed with cancer between August 1, 2009 and December 31, 2015 in Rio Grande do Sul, who received hospital treatment in institutions affiliated with the Universal Health Care System (Sistema Unico de Saude [SUS]). Results Most children and adolescents were male (56.9%) and White (75.8%). The most common types of cancer in our cohort were acute leukemia (40.7%), followed by lymphoma (15.9%) and central nervous system tumors (8.8%). Ninety-five percent of the patients were treated in specialized pediatric oncology centers. The cumulative probability of survival at 5 years for all patients was 73.8% (95% confidence interval [CI] 71.4-76.0%). Survival was significantly higher for patients younger than 4 years of age (P = .012) compared to all other age groups. Patients treated in institutions with a pediatric oncology patient volume of less than 15 patients/year were 41% more likely to die than patients treated in institutions with a volume of 60 patients/year or more (P = .029). Conclusion Cancer is the leading cause of death by natural causes in all age groups in Brazil, but, even so, childhood tumors are rare. This complexity makes childhood cancer care a challenge. In this study, we reiterate that pediatric cancer patients demonstrate better overall survival when treated in high-volume hospitals.
