Abstract

in English, Chinese

Objective: To investigate the clinical features, survival and prognostic risk factors of children with hepatoblastoma (HB).

Methods: Clinical data of 83 children with newly treated HB at the Department of Hematology and Oncology, Children's Hospital, the First Affiliated Hospital of Zhengzhou University from January 2012 to October 2019 were analyzed retrospectively. The sex, age, first clinical manifestations, pretreatment extent of disease (PRETEXT) stages, pathological types, initial alpha-fetoprotein (AFP), treatment methods and treatment outcome of all patients were summarized. The children diagnosed before 2018 were treated with "Wuhan Protocol", and those who diagnosed after 2018 were treated with the "Expert Consensus for Multidisciplinary Management of Hepatoblastoma"(CCCG-HB-2016) protocol. Kaplan-Meier survival analysis was used to calculate the survival rate, Log-Rank test was used in univariate analysis, and the Cox regression model was used in multivariate prognosis analysis.

Results: Among 83 cases, there were 51 males and 32 females. The age of onset was 25.2 (9.0, 34.0) months old, and 64 cases (77%) were under 3 years old. The most common first clinical manifestation was abdominal mass in 45 cases (54%). There were 8 cases of PRETEXT stage Ⅰ, 43 cases of stage Ⅱ, 20 cases of stage Ⅲ and 12 cases of stage Ⅳ. During the follow-up period of 40 (17, 63) months, the 1-year overall survival (OS) rate and event-free survival (EFS) rate were (84±4) % and (79±5) %, respectively, and 5-year OS rate and EFS rate were (78±5) % and (76±5) %, respectively. Fifty-five cases were treated with "Wuhan Protocol", and the 5-year OS and EFS rate were (73±6) % and (71±6) %, respectively. Twenty-eight cases were treated with CCCG-HB-2016 protocol, and the 5-year OS and EFS rate were (88±7) % and (82±9) %, respectively. Multivariate COX regression analysis showed that AFP did not turn negative after 3 courses of postoperative chemotherapy (HR=9.228, 95%CI 1.017-83.692) and PRETEXT stage Ⅳ (HR=6.587, 95%CI 1.687-25.723) were independent risk factors affecting the prognosis of children with HB

. Conclusions: The "Wuhan Protocol" and CCCG-HB-2016 protocol were effective in the treatment of children with HB. AFP did not turn negative after 3 courses of postoperative chemotherapy and PRETEXT stage Ⅳ were independent risk factors affecting the prognosis of children with HB.
