Background and purpose: This study describes clinical outcomes of palliative radiation therapy (RT)for children treated in distinct health-care environments—the US where there is advanced integration of palliative resources and Brazil, a country in the process of developing provisions for pediatric palliative care. Methods and materials: Palliative RT cases of pediatric oncology patients aged ≤21-years from 2010 to 2016 in two Brazil-based and one US-based (Johns Hopkins Hospital, JHH)academic centers were reviewed in this study. Results: Eighty-eight pediatric patients were treated to 131 lesions with palliative RT. Forty-nine patients from the JHH cohort comprised 84 cases and 39 patients from the Brazil cohort comprised 46 cases. The most common indication for palliative RT was pain (55% overall, 39% Brazil, 63% JHH). Sixty-seven percent of patients experienced a complete (CR)or partial response (PR)to palliative RT, 12% reported stable symptoms (SS), and 22% reported progressive symptoms (PS). The median survival from the end of palliative RT was 3.6 months (95% confidence interval (CI), 2.3–4.8 months). When treated with palliative RT for pain, 83% of patients experience CR/PR, facilitating reduction or discontinuation of opiates in 46% of these patients. Conclusion: Despite different practices, the clinical results using palliative RT for pediatric patients treated in two unique healthcare environments demonstrated it is an effective tool for pediatric oncology patients across systems.
