Abstract:

Objective: To summarize and analyze the treatment process, long-term efficacy and clinical economics of children’s hepatoblastoma (HB) in multi-disciplinary team (MDT) mode, so as to provide basis for the rational choice of diagnosis and treatment.Methods: From January 2014 to February 2019, 13 cases of hepatoblastoma in children who completed the whole treatment course in the Pediatric Hematology Tumor Ward of Peking University First Hospital were collected and analyzed, and were followed up until June 30, 2020. There were 9 males and 4 females who were diagnosed and treated according to the MDT process in the hospital. The median age was 16 months (2-54 months), 69.23% (9/13) were under 2 years old. The characteristics, diagnosis and treatment process and treatment effect of the cases were summarized, and the cost of clinical treatment was analyzed.Results: According to the pretreatment extent of disease(PRETEXT), there were 1, 9 and 3 children with stages Ⅱ, Ⅲ and Ⅳ. 76.92% (10/13) of the patients had the largest tumor diameter > 10 cm. All the patients received preoperative neoadjuvant chemotherapy (8 patients received 4 cycles of chemotherapy, and 6 patients changed the chemotherapy plan), surgical treatment and postoperative chemotherapy, the tumor volume decreased by more than 50% (64%-95%) in 12 cases, except 1 case with no significant increase of alpha fetal protein and multiple lesions .The median length of stay was 87 days (68-214 days), the median cost of stay was 200 000 yuan (115 000-500 000 yuan), the median length of stay was 7 days (5-17 days), the median cost of stay was 20 000 yuan (15 000-60 000 yuan), and the incidence of postoperative complications was 7.69% (1/13). All the patients were followed up for 16-69 months. All the patients survived.Conclusion: Under the MDT mode, the treatment is seamless connection, the long-term prognosis of children with HB is good, and the total hospitalization cost and time are within the acceptable range. Standard preoperative neoadjuvant chemotherapy can significantly reduce the tumor, improve the resection rate, reduce postoperative complications, reduce the total individual expenditure, shorten the total hospital stay, and further improve the long-term disease-free survival rate.
