Quality of life in children with brain tumors post radiotherapy in a lower-middle income country.

Indonesia is a rapidly growing lower-middle-income country (LMIC) located in Southeast Asia. It has 267.3 million inhabitants, with 31.6% (84.4 million) children. According to GLOBOCAN 2020, Indonesia had the highest prevalence of pediatric cancer cases in Southeast Asia (43.5%), and brain tumors had the third-highest incidence in Indonesia. Treating children with brain tumors with radiotherapy is challenging, especially the late treatment effects that can affect their quality of life (QoL). This study aimed to show the QoL in children with brain tumors after radiotherapy in Dr. Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia, based on PedsQL™ 4.0 generic core scale and the possible affecting factors. In this cross-sectional study, 26 of 88 children with brain tumors after radiotherapy were assessed by the PedsQL™ 4.0 generic core scale. Of the 88 patients who had brain tumor radiotherapy in 2014-2019, 31 patients were lost to follow-up, 28 were confirmed dead, and 29 were assured alive. One-year, three-year, and five-year overall survival were 71.6%, 43.2%, and 5.7%, respectively. The mean of children's QoL was 70.686 and 70.152 based on child self-report and parent proxy-report. Family income > 290 USD (regional minimum wage) was a factor that improved the QoL in children with brain tumors after radiotherapy (p = 0.008). QoL in children with brain tumors after radiotherapy could be influenced by family income.
