Hepatoblastoma (HB), is a malignant neoplasm, which originates in the liver. Survival (SV) depends on the extent of disease progression. The objective of this study was to determine differences in overall SV (OS) and disease-free (DFS) in patients with HB, according to the extent of their disease. Case series with follow-up. Patients between 4 and 160 months of age treated at an oncology center in the Ecuadorian Andes (2000-2019) were included. The result variables were affected lobe, lung metastasis, vascular infiltration, PRETEXT stage, risk, histology, alpha-fetoprotein levels (AFP), complete remission (RC), OS and DFS. Descriptive and analytical statistics (Chi2, Fisher's exact and continuity correction) were used. SV analyzes were performed with Kaplan Meier and log-rank curves. In this analysis 28 patients (53.6 % men), with a median age of 40 months, were studied. Lung metastases and vascular infiltration were verified in 25.0 % and 35.7 % of the cases, respectively. Histology, clinical stage, and high risk were mainly epithelial type (42.8 %), PRETEXT II (50.0 %), and high risk (67.8 %), respectively. The mean AFP at diagno- sis was 1055712 ng / ml and 9 patients achieved CR. OS and DFS at 19 years were 33.1 % and 26.0 % respectively. According to their extension, the OS and DFS for standard and high risk patients were 50.0 % and 25.4 % (p = 0.148); and 50.0 % and 14.7 % (p = 0.037) respectively. The verified OS and DFS are lower than those reported in other studies. DFS according to its extension, presented a significant difference, however, this result should be considered with caution due to the small number of patients.
