Radiological response and inflammation scores predict tumour recurrence in patients treated with transarterial chemoembolization before liver transplantation

¹For radio-histological correlation of the target lesion response, the percentage of necrosis on CTA was re-calculated considering only nodules ≥ 1 cm in diameter. CTA: Cumulative Tumour Area; mRECIST: Modified Response Evaluation Criteria in Solid Tumours; EASL: European Association for the Study of the Liver.
