Liver Transplant in Children with Hepatoblastoma

In this paper, the results of liver transplant due to hepatoblastoma in 10 pediatric patients at Istanbul Şişli Memorial Hospital Transplantation Center are presented.We retrospectively evaluated medical records of pediatric patients diagnosed with hepatoblastoma and who underwent liver transplant at our clinic between January 2009 and March 2014. We examined age, weight, chemotherapy regimen, graft type for liver transplant, duration of hospital stay, complications, follow-up duration, and survival information.The median age of the 10 patients included in our study was 13.5 months (range, 8-120 mo), and the median weight was 10 kg (range, 6.5-30 kg). Two of the patients were twins. Five patients had pretreatment extent of disease III (centrally placed cases), and five had pretreatment extent of disease IV hepatoblastoma. Preoperative chemotherapy was given to 7 patients as cisplatin plus doxorubicin and to 3 patients per the International Childhood Liver Tumors Strategy Group 3 High-Risk Protocol at external centers. These protocols were administered according to treatment center preference. Nine patients received transplants from living donors. Two grafts were right lobes, and 7 were left lateral segments. In the remaining patient, a whole liver was received from a deceased donor. The histopathologic subgroups were epithelial in 5 patients, with others being of mixed type. Postoperative complications occurred in 3 patients as infection, intra-abdominal fluid collection, and acute rejection. The median follow-up was 32 months. One patient died because of lung metastasis within 9 months after transplant.Centers should offer liver transplant to patients with centrally located tumors. For centers that have an insufficient number of deceased donors, living-donor liver transplant with optimal planning and early treatment can be performed.
