Selective portal embolization combined with chemotherapy treatment in non-resectable liver tumors reduces tumor volume and generates contralateral compensating hypertrophy allowing for a full resection while avoiding liver transplantation.

INTRODUCTION Non-resectable liver tumors are one of the most frequent indications of pediatric liver transplantation. However, the usefulness of interventional techniques is still to be exploited. This is the case of a patient with a non-resectable liver sarcoma proposed for liver transplantation, which could be avoided as the tumor was fully resected following selective portal embolization combined with chemotherapy treatment. CLINICAL CASE The patient was a 10-year-old female with a large hepatic mass compatible with undifferentiated PRETEXT III sarcoma treated according to the EpSSG RMS2005 protocol for high-risk tumors, but without achieving any reduction in volume. Given the risk of developing a small-for-size syndrome following a potential resection, a right portal embolization was performed in order to induce left hemi-liver hypertrophy. No response was observed after two months, so the patient was included on the liver transplantation list. However, one month later, a significant reduction in mass volume was noted at a control CT-scan, which meant the tumor could be resected while avoiding transplantation. The one-year follow-up was uneventful. DISCUSSSION Interventional techniques should be considered as the main therapeutic option in non-resectable liver tumors, since they could potentially avoid transplantation in selected patients.
