Investigating paediatric sarcoma management worldwide: a study protocol

Cancer is the leading cause of non-accidental death among children worldwide. The most common types of paediatric cancers include sarcomas: a group of cancers that are difficult to manage due to their heterogeneity and lack of defining features. We have designed an international multicentre cohort study to assess the management of paediatric sarcomas at tertiary healthcare centres in Nigeria, Pakistan and the UK. The centres will screen patient databases to identify eligible patients under the age of 18 with a clinical or histological diagnosis of sarcoma. Data will be extracted from the patient notes through an anonymized form. Patients will be recruited consecutively into the study from January 2015 to January 2021, with a minimum 12-month follow up period. The primary objectives of the study will be to determine all-cause mortality rates at 30 days, 90 days, 12 months and 3 years. Significant differences in mortality rates between countries will be determined using χ2 analysis or Fisher’s exact test. Univariate and multivariable logistic regression will be used to examine the influence of different factors and patient characteristics on outcomes. At the host centre, this study was deemed to be exempt from ethical committee approval due to the use of anonymized data. At other centres, participating collaborators have gained local approvals in accordance with institutional ethical regulations. Collaborators will present the data to inform decision makers about how sarcoma management may be improved. The results will be submitted for publication in a peer-reviewed journal.
