Ewing Family Tumour (EFT) is a group of rare malignant and aggressive tumour, with a considerably improved prognosis. However, there is lack of study on the outcome of children with EFT in Malaysia. Objectives: The study aimed to evaluate the Overall Survival (OS) rate, Event Free Survival (EFS) rate and identify the prognostic factors that determined the EFT outcome at Hospital Universiti Sains Malaysia (USM). Methodology: A retrospective record review of children aged 0-18 years with EFT was done. Patients were identified from the registration data in the Oncology Unit and Record Office of Hospital USM. For patients with untraceable information or deceased, a letter was sent to State Registry to obtain the outcome of the patient. The association between demographics and patients’ clinical factors was determined using the Cox regression. Survival curves were estimated by the Kaplan-Meier method and were compared using the Log-rank test. Results: There were 51 patients identified but 29 of them were eligible for the study. The mean duration of follow-up was 21 months. The OS rate at 1, 2, 3 and 5 years were 62.1%, 44.8%, 30.2% and 21.6% respectively. The EFS rate at 1, 2, 3 and 5 years were 41.9%, 26.7%, 17.8% and 0% respectively. Multivariate Cox regression analysis showed that the presence of surgical intervention (p = 0.030) and major complications (p = 0.045) were the significant prognostic factors to the survival of EFT. Conclusion: The survival rate of EFT among our patients was comparable to other developing countries, with surgical intervention and the presence of major complications as independent prognostic factors.
