Preoperative treatments aimed at downsizing the tumor and promoting hypertrophy of the future remnant liver may improve resectability and reduce operative morbidity. Here we report the case of a patient with a large hepatocellular carcinoma arising from chronic liver disease. Preoperative treatment, including tumor downsizing with transarterial radioembolization and induction of future remnant liver hypertrophy with right portal vein embolization, resulted in a 53% reduction in tumor volume and compensatory hypertrophy in the contralateral liver. The patient subsequently underwent extended right hepatectomy with no postoperativesigns of liver decompensation. Pathological examination demonstrated a margin-free resection and major tumor response. This new therapeutic sequence, combining efficient tumor targeting and subsequent portal vein embolization, could improve the feasibility and safety of major liver resection for hepatocellular carcinoma in patients with liver injury.展开更多

We describe the case of a cirrhotic Child-Pugh A patient with a segment Ⅳ hepatocellular carcinoma requiring a left hepatectomy. Preoperative angiography demonstrated 2 separated left hepatic arteries, for segment Ⅳ and segments Ⅱ-Ⅲ. This anatomic variant allowed sequential radioembolizations, delivering high-dose ^(90)Yttrium(160 Gy) to the tumor, followed 28 d later by lower dose(120 Gy) to segments Ⅱ-Ⅲ. After 3 mo, significant tumor response and atrophy of the future resected liver were obtained, allowing uneventful left hepatectomy. This case illustrates that, when anatomic disposition permits it, sequential radioembolizations, delivering different ^(90)Yttrium doses to the tumor and the future resected liver, could represent a new strategy to prepare major hepatectomy in cirrhotic patients, allowing optimal tumoricidal effect while reducing the toxicity of the global procedure.展开更多
