Extracorporeal hepatic resection and autotransplantation using temporary portocaval shunt provides an improved solution for conventionally unresectable HCC

摘要

Hepatic resection is the gold-standard treatment for hepa-tocellular carcinoma (HCC). In East Asia, however, only 20 % of patients with HCC are eligible for hepatectomy [1]. In a small subset of patients, surgical resection using conventional techniques is extremely challenging. In these marginal cases, the tumor size, extension of the lesion, and proximity of the tumor to critical structures are important factors determining how to proceed. For tumors considered unresectable by conventional means, extracorporeal hepatic resection with autotransplantation (ECHRA) has been proposed to be an alternative [2]. ECHRA has been used to treat hepatic pathologies including giant hemangioma [3], liver metastases [4], and sarcomas [2]. However, few studies have reported on its application as a treatment for HCC [5]. Herein we report a case series involving three consecutive patients with HCC who were successfully treated with ECHRA as curative therapy for otherwise unresectable HCCs.
