Who cares for adolescents and young adults with cancer in Brazil?

Abstract

Objective: Approximately 6% of all cancers arise in adolescents and young adults. Currently, the ward type best placed to treat this patient group remains controversial. The aim of this study was to evaluate exactly where adolescents and young adults with cancer are treated in Brazil. Methods: Data were extracted from 271 Brazilian hospital-based cancer registries (2007–2011), including all five national regions (North, Northeast, Midwest, South, and Southeast). Variables included gender, age, ethnicity, National Code of Health Establishment, hospital unit state, and region. Tumors were classified according to the World Health Organization classification for adolescents and young adults with cancer. Odds ratios with 95% confidence intervals were computed by unconditional logistic regression. Results: Most patients were managed on medical oncology wards, followed by pediatric oncology and then by non-specialist wards. Of patients aged 15–19 years, 49% were managed on pediatric wards; most of the older patients (96%; aged 20–24) were managed on adult wards. Patients were more likely to be seen in medical oncology wards as their age increased (OR = 2.03 [1.98–2.09]), or if they were based in the South (OR = 1.50 [1.29–1.73]). Conversely, bone tumors were less likely to be treated (decreased OR) on medical oncology wards, regardless of age, gender, and region. Conclusion: An elevated risk of treatment on medical oncology wards was observed for older patients and those treated in the South. Bone tumors were generally treated in pediatric oncology wards, while skin cancers were treated in medical oncology wards, regardless of age, gender, and region.
