RESUMO
Background: The cornerstones of successful treatment of hepatoblastoma (HB) include preoperative chemotherapy followed by complete anatomical resection of tumor, followed by chemotherapy. Advances in chemotherapy in the last 2 decades have been associated with a higher rate of tumor response and possibly a greater potential for resectability. Aims: We analyzed our single center experience with neoadjuvant chemotherapy (NACT) and surgery in HBs. Settings and Design: Our study included all children with HBs who received NACT and underwent surgical excision from January 1997 to July 2004. Materials and Methods: Patient characteristics, clinical features, clinical course, treatment modalities, and long-term outcome were analyzed. Results: There were 9 boys and 3 girls, aged 5-60 months (median age at tumor diagnosis was 24 months). All received NACT containing cisplatin and doxorubicin. Of the 12 children, 9 underwent hepatectomy and among them, 4 patients each had right and left hepatectomy and 1 patient underwent right extended hepatectomy. After surgery, all patients completed rest of the chemotherapy course (total 6 cycles). R0 resection was carried out in all the 9 cases with no life-threatening complications. Conclusions: Our experience of the 9 cases, although less in number, reaffirms the advantages of NACT followed by surgery. The prognosis for patients with resectable tumors is fairly good in combination with chemotherapy.

El hepatoblastoma es el tumor hepático primario maligno más frecuente en el niño; en el adulto, es extremadamente raro y sólo 27 casos han sido descritos en la literatura. El pronóstico de esta neoplasia es malo debido a que habitualmente se descubre en forma tardía. La cirugía, la quimioterapia y el trasplante hepático han sido utilizados como tratamiento con malos resultados. Presentamos dos pacientes adultos a quienes se les diagnósticó hepatoblastoma epitelial. Se hace una revisión de su patogénesis, características clínicas, histológicas y manejo actual
