Abstract:
Objective:To investigate the efficacy and the prognostic factors in pediatric hepatoblastoma according to the standard diagnostic and therapeutic regimen.
Method:Eighty-four consecutive patients were enrolled in this study between June 2000 and June 2015. Diagnosis and staging was decided by the multi-disciplinary team including oncologists, surgeons, pathologists and sub-specialized radiologists refering to protocol of Children′s Oncology Group(COG) and International Society of Pediatric Oncology Liver Tumor Study Group (SIOPEL) in a case observational study. Univariate analysis was tested by the log-rank and multivariate analysis by COX regression. All consecutive cases were divided into low risk group and high risk group according to grouping criteria. Complete remission was defined as both imaging negative and α fetoprotein (AFP) normalization. Retrospective analysis was performed in clinical features, long-term outcomes and prognostic factors.
Result:Ten patients were excluded because of giving up after less than or equal to three cycles of treatment. A total of 74 cases were included in this study; 45 males and 29 females. The median age at diagnosis was 1.7 years(range 0.2-14.8 years). Untill August 30, 2016, the median follow-up time was 24.2 months (range 4.1-135.3 months); 59 cases achieved complete remission.The estimated five years overall survival (OS) and event free survival(EFS) were 90%(68/74)and 72%(58/74). AFP could be normalized after 5 circles of treatment or 2 circles of postoperation.In univariate analysis , the five years OS and EFS in low risk group were both 100%(18/18), and those in high risk group were 88%(50/56)and 68%(40/56), respectively. The five years OS rates were 75%(15/19) and 95%(53/55) in patients with or without distant metastasis (P=0.016). After 3 cycles of chemotherapy post tumor resection, we divided these patients into 2 groups according to AFP recover or not, the five years OS were 100%(43/43)and 81%(22/26), respectively (P=0.011).
Conclusion:The result of this protocol is reasonable when comparing with other worldwide research. Except for staging, metastasis, pathological subtypes, postoperative AFP recover or not is a prognostic factor after 3 cycles of chemotherapy.
