Most patients present with advanced, high-risk disease and 90 % are less than five years old. The burden of morbidity and mortality is high and is quantifiable by measures of health-related quality of life (HRQL). Measuring quality of life in under five-year-old children is a particular challenge that has been met with the development of the Health Utilities Pre-School (HuPS) instrument. Quality of life studies in children with cancer are scarce in low- and middle-income countries and are usually conducted at a single center, thus limiting any conclusions drawn. This pilot study aimed to assess the health-related quality of life of children at the time of diagnosis of high-risk neuroblastomas.</p><p><strong>Method: </strong>This prospective cross-sectional multicentric study assessed the quality of life of children with high-risk neuroblastoma. The Health Utilities Pre-School instrument was applied to under five-year-olds, and the related Health Utilities Index Mark 3 instrument to over five-year olds.</p><p><strong>Main results: </strong>Eleven patients participated in this study. There was a high burden of morbidity at diagnosis, often equating to severe disability, indicative of states of health with scores worse than being dead in two under five-year-old children.</p><p><strong>Conclusion: </strong>The results of the current study will help to set research priorities for subsequent investigations and provide a basis to improve supportive care for children with high-risk neuroblastoma.</p>","PeriodicalId":94026,"journal":{"name":"Hematology, transfusion and cell therapy","volume":" ","pages":"S228-S233"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142304627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
