Abstract

Abstract: Background: Undifferentiated embryonal sarcoma of the liver (UESL) is a rare liver tumour that occurs mainly in children. Herein, we aimed to identify any differences in clinical characteristics and survival between adult and paediatric patients with UESL. Methods: From 1975 to 2015 in the Surveillance, Epidemiology and End Results (SEER) database, patients diagnosed with UESL were identified and divided into paediatric (<18 years) and adult (≥18 years) groups. We then compared the clinical characteristics, management, and overall survival (OS) of adults and children diagnosed with UESL. Results: We analysed 113 patients with UESL (81 children and 32 adults). UESL was significantly more common in adult male than paediatric male patients (71.9% vs. 48.2%; P = 0.022). When compared to adult patients, paediatric patients were more likely to receive chemotherapy (93.8% vs. 65.6%; P < 0.001). Adults had a significantly worse OS than paediatric patients (5‐year OS, 30.0% vs. 81.2%; P < 0.001). Univariate analysis found that adult age, surgical therapy and chemotherapy were associated with OS. Multivariate analysis revealed that adult age, SEER summary stage and surgical therapy were independent prognostic factors for OS. Conclusions: UESL had a male predominance among adult patients. Moreover, the prognosis of adult patients with UESL was significantly worse than that of paediatric patients. Surgery and chemotherapy should be considered in the treatment of patients with UESL. Abstract : In this study, by using SEER database, we compared clinical characteristics and survival between adult and pediatric patients with undifferentiated embryonal sarcoma of the liver.
