Prognostic analysis of 48 children with hepatoblastoma after pulmonary metastasectomy / 国际儿科学杂志

ABSTRACT

Objective:To summarize the prognostic characteristics of hepatoblastoma in children undergoing pulmonary metastasectomy.Methods:The clinical data of 48 hepatoblastoma patients with pulmonary metastases who underwent pulmonary metastases resection in our hospital from January 1 2009 to December 31, 2017 were collected, and prognosis of these patients was analyzed.Results:Forty eight cases were diagnosed as hepatoblastoma with pulmonary metastasis, including 30 cases with pulmonary metastasis alone and 18 cases accompany with other high risk factors affecting prognosis. All the 48 patients underwent pulmonary metastasectomy, in which 43 patients were given pulmonary metastases resection completely and 5 patients were given partial resection of metastases. Twenty-five cases recurred after the first pulmonary metastasis resection(25/48, 52.1%), and 2 cases progressed. With the median follow-up time of 45.5 months, survival time of 48 patients with pulmonary metastasectomy was(83.59±7.01)months, and the 3-year overall survival rate was 58%. Of the groups those were patients with pulmonary metastasis alone and patients with other high risk factors affecting prognosis, the survival time and the 3-year overall survival rate showed a significant statistical differences[(95.89±8.19)months vs.(58.95±9.40)months; 79.4% vs.50%; χ2=4.849, P= 0.028)]. The survival time and 3-year survival rate of the two groups between with recurrence or progression and the group without recurrence or progression after pulmonary metastases resection were showed a significant difference[(56.84±7.22)months vs.(112.48±7.08)months; 55.6% vs.90.5%; χ2=11.03, P= 0.001)]. Results of COX regression analysis showed that the main risk factor affecting prognosis was pulmonary metastasis accompany with other high-risk factors for hepatoblastoma patients. The death risk of patients with pulmonary metastasis accompany with other high-risk factors was 3.424 times than that of patients without other high-risk factors( RR=3.424, 95% CI 1.264~9.275). Conclusion:The overall prognosis of patients with pulmonary metastases is not good, and the proportion of postoperative recurrence is very high. Pulmonary metastasis accompanied with other high risk factors is the main risk factor affecting the prognosis of patients with pulmonary metastasectomy.
