Hepatocellular carcinoma (HCC) involving the inferior vena cava (IVC) and/or right atrium (RA) is a rare and intractable disease. A standard treatment has not been established yet, owing to the rarity of disease and difficulties in the therapeutic treatment. Herein, we report the case of a patient who had recurrent HCC (after a prior lobectomy) involving both IVC and RA and underwent multimodality treatments including external beam radiotherapy and transarterial chemotherapy, followed by sorafenib treatment. The disease was well controlled with local treatments and sustained for 7 years until last follow-up after the systemic treatments. Our case shows a possibility of long-term survival for patients affected by HCC involving IVC and/or RA, after a rigorous multimodality treatment strategy.
Advanced hepatocellular carcinoma (HCC) with tumor thrombus extending through the hepatic veins, inferior vena cava, and right atrium (RA) is very rare. However, whether active treatments such as radiation, transcatheter arterial chemoembolization, and sorafenib in advanced HCC with RA involvement prolong survival is uncertain. We present a rare case of advanced HCC with tumor thrombus nearly occupying the entire RA that was treated with sorafenib. The patient received 400 mg sorafenib twice daily. However, her liver enzyme levels continued to increase and abdominal computed tomography showed an increase in the tumor size in the liver and RA.
In the present case, active treatment with sorafenib was ineffective; thus, palliative care may be more beneficial in advanced HCC with extensive RA involvement.

In patients with advanced hepatocellular carcinoma (HCC), tumor thrombus in inferior vena cava (IVC) and right atrium (RA)
are not uncommon findings and are usually associated with extremely poor outcome. Although aggressive surgical interventions
such as extracorporeal circulation and tumor excision have been performed, the reported results were still unsatisfactory. Herein,
we report the favorable result of combined treatment with radiation therapy and transarterial chemoembolization in a patient with
advanced HCC with extensive tumor thrombus through the IVC into the RA. In conclusion, noninvasive combined modalities,
such as transarterial chemoembolization and radiation therapy may sometimes provide effective palliation for patients with far
advanced HCC with IVC/RA tumor thrombus and who are not candidates for alternative treatment options.
Hepatocellular carcinoma (HCC) with extension of its tumor thrombus into the inferior vena cava (IVC) and
right atrium has been regarded as beyond the realm of surgical resection. It could cause sudden death due to
pulmonary embolism or heart failure by the detached fragments of tumor thrombus. In recent years, successful
surgery has been reported for hepatic malignancies with its tumor thrombus to the IVC and right atrium by some
centers of Taiwan and Japan. We also did a successful en bloc resection of the liver tumor and its tumor
thrombus in the IVC and right atrium using cardiopulmonary bypass and report herein.
A 52 year-old-male patient was admitted to our hospital due to hematemesis. Ten years ago, he had been diagnosed chronic hepatitis B and he was heavy alcoholics. He was in the state of SB tube insertion and we had esophagogastroduodenoscopy and found out cardiac varix bleeding and injected history1. On abdominal ultrasonograpy, large hypoechoic mass in left lobe of liver was noted and the mass invaded into hepatic vein, inferior vena cava (IVC), and right atrium. On hepatic arteriography, large hypervascular mass in left lobe of the liver and several small dodules in right lobe were noted. We performed chemoembolization to the nodules in right lobe but cannot performed to the lesion in left love due to arteriovenous shunt. We inserted the chemport catheter to proper hepatic artery and started the intra-arterial chemotherapy (IACT) with 5-FU 250 mg and cisplatin 10 mg for 5 days. After the second cycle of IACT, tumor thrombus in right atrium was disappeared and thrombus in IVC and tumor mass in left lobe were decreased in size. We believed that hepatocellular carcinoma of this patient should be sensitive to chemotherapy and planned the additional IACT treatment.
