In order to achieve complete resolution of the disease,
          surgery was offered. Pre-operative assessment showed that
          the liver function was satisfactory for a major hepatectomy
          (with a 6.6% indocyanine green retention rate at 15 min), and
          there would be an adequate left-liver remnant. Laparotomy    a               b
          was conducted in October 2012. The tumor was found to
          have infiltrated to the right adrenal gland and the whole
          length of the retrohepatic IVC. The left liver lobe had an
          adequate volume and was free of tumor. The right lobe,        c              d
          the caudate lobe of the liver, the right adrenal gland,
          and the IVC were resected en bloc [Figure 2]. Immediate
          reconstruction of the IVC was performed using a cadaveric
          vein graft (5.5 cm long, 2.5 cm wide) [Figure 3]. The entire
          operation lasted 10 h and the total IVC cross-clamping time          e
          was 1 h. There was 1.2 L of blood loss.             Figure 1: Preoperative computed tomographic scans showing tumor invasion

          After the operation, the patient was put on everolimus
          (1 mg daily). He was discharged 12 days after the
          operation. Histopathological examination of the resected
          specimen showed necrotic tumor in the right liver lobe
          and viable metastatic HCC with the involvement of the
          right adrenal gland. No viable tumor was seen in the IVC
          thrombus. The patient was followed-up every 2 months
          after the operation and had remained free of disease
          (radiologically and biochemically) for more than 27 months
          at the time of writing this manuscript.

          DISCUSSION

          At the beginning, the treatment was meant to be either
          palliative or neoadjuvant, depending on the radiological
          and biochemical responses. Ultimately, mixed responses   Figure 2: En bloc resection of the inferior vena cava, right liver lobe, and right
                                                              adrenal gland
          were observed. Disease at the metastatic lymph nodes
          regressed and the AFP level rebounded substantially over a
          period of time after treatment. Aggressive surgical resection
          was offered, and major vascular resection was needed for a
          potentially curative resection. Sorafenib was continued as
          an adjuvant therapy. It is hoped that the efficacy and safety
          of sorafenib in adjuvant treatment of HCC after potentially
          curative treatment will be demonstrated when the results of
          the   STORM (sorafenib as adjuvant treatment in the prevention
          of recurrence of HCC) trial are released. A recent German
          multi-center Phase II trial showed that the combination of
          TACE and sorafenib could achieve a 74.4% disease control
          rate according to the criteria set by the European Association
          for the Study of the Liver. Among the 43 patients, 7% had a
          complete response, 41.8% had a partial response, and 25.6%
          had stable disease.  Downstaging by sorafenib alone was   Figure 3: Reconstruction of the inferior vena cava with a cadaveric vein graft
