Successful resection for advanced hepatoblastoma, combined with perioperative chemotherapy.
The aim of this study was to evaluate our results of surgical treatment with intensive perioperative chemotherapy for hepatoblastoma in infants and children. Seven patients (mean age, 30 months; range 1 month to 6 years) with hepatoblastoma who were followed-up for more than 3 years were reviewed. All patients underwent hepatectomy, performed using a microwave tissue coagulator, after they had received neoadjuvant chemotherapy comprising up to four cycles of cisplatinum and doxorubicin. The main outcome criteria were the clinical response rates to neoadjuvant chemotherapy and the overall survival. Neoadjuvant chemotherapy markedly reduced the tumor volume on computed tomography (mean regression rate, 73%). Alpha-fetoprotein (AFP) levels also decreased, from a mean value of 138 x 104 to 990 ng/ml (excluding values for one patient with tumor thrombus in the portal vein). The surgical procedures included extended right lobectomy in one patient, extended left lobectomy in two patients, hepatic left trisegmentectomy in one patient, and hepatic subsegmentectomy in three patients. The postoperative clinical courses in all seven patients were good, and no serious complications were observed. No relationship was observed between the DNA ploidy pattern and the histopathological findings of the resected specimens regarding survival. Six patients (excluding the patient with a tumor thrombus in the portal vein) who underwent complete resections survived without any signs of recurrence during a follow-up period ranging from 47 to 150 months. In conclusion, the perioperative chemotherapy greatly improved both the resection rate and overall survival in patients with hepatoblastoma. DNA ploidy pattern analysis may be useful when predicting the prognosis of patients with hepatoblastoma. The use of the microwave coagulator was safe for performing hepatectomy, even in infants.
