Macrovascular invasion, such as tumor thrombus in the major portal vein (mPVTT) or major hepatic vein (mHVTT), is regarded as indicative of an advanced stage of hepatocellular carcinoma (HCC). To date, no effective treatment has been established for this kind of HCC. We herein present a case of huge HCC with intrahepatic metastasis, mPVTT, and mHVTT. The patient was successfully treated with surgical resection-based multidisciplinary treatment. The clinical presentation, treatment strategy, and outcome of this case were presented.

| > Introduction|| |
A large number of hepatocellular carcinoma (HCC) patients have intrahepatic metastasis together with major portal vein tumor thrombus (mPVTT) or major hepatic vein tumor thrombus (mHVTT) at diagnosis., However, the optimal treatment for HCC patients with intrahepatic metastasis and mPVTT/mHVTT remains controversial.,,,
Evidence from studies suggests that surgical resection-based multidisciplinary treatment (MDT) including transcatheter arterial chemoembolization (TACE), radiofrequency ablation (RFA), or sorafenib in patients with HCC may provide better outcomes than each approach alone.,, We herein report a case of huge HCC with intrahepatic metastasis, mPVTT, and mHVTT who was successfully treated with surgical resection-based MDT.
| > Case Report|| |
A 56-year-old Chinese man was found to have advanced HCC. The patient is a hepatitis B virus (HBV) carrier but does not have liver cirrhosis. His initial symptom was significant weight loss. The patient did not claim any abdominal discomfort. The patient underwent TACE 1 month before admission to our hospital. Contrast-enhanced computed tomography (CT) revealed a huge carcinoma in the right lobe with areas of lipiodol deposition. Another lesion in the segment 2 was also detected. Tumor thrombi were found in the left and right portal vein, the main portal vein trunk, and the right hepatic vein [Figure 1]. Magnetic resonance images and positron emission tomography/CT showed similar findings to CT. Preoperative biochemical examinations showed alpha-fetoprotein (AFP) was 6427 ng/mL, HBV-DNA was <5.0 × 102 copies/mL. The patient's Child-Pugh score was five points (Class A), the model for end-stage liver disease score was eight, and the Eastern Cooperative Oncology Group (ECOG) Performance Status was zero. The patient was classified by the barcelona clinic liver cancer system as Stage C and tumor, node, metastasis staging system as IIIb.

The patient subsequently underwent nonanatomic resection of the right liver and segment 2. Macroscopically, the liver was almost normal. The main tumor was about 12 cm × 12 cm. In the segment 2, a 3 cm × 3 cm metastatic lesion could be found. For PVTT, the right and left portal veins were exposed and incised, and thrombectomy was performed, respectively. For HVTT, the right hepatic vein was ligated at root site and the HVTT was resected en bloc with the tumor [Figure 2].

The postoperative course was uneventful. The AFP level was decreased to 458 ng/mL on the 13th postoperative day [Figure 3]. The patient was discharged on the 19th postoperative day. Two months after surgery, metastatic lesions in the liver segment 5, left portal vein, and lung were detected. The patient then underwent three times TACE and twice RFA for liver and portal vein lesions successively, and once RFA for lung lesions. During this period, the patient has taken sorafenib (800 mg/day) in combination with S-1. Antiviral drug was also taken. Serum AFP assays were performed every 1–2 months and showed a gradual decrease but increased again in the latest 9 month [Figure 3]. Contrast-enhanced CT scan was also performed every 2–3 months for evaluation of treatment efficiency. Until April 2016, the patient had been alive for 20 months with an ECOG performance status of zero. This article was approved by the Ethics Committee at our institute. Informed consent was obtained from the patient.

| > Discussion|| |
In the present report, the patient, who was found to have a huge HCC with intrahepatic metastasis, mPVTT, and mHVTT, underwent aggressive MDT combining surgery with the subsequent administration of sorafenib, repeated TACE and RFA. The patient achieved an acceptable survival of more than 20 months. So far, two studies of sorafenib as an adjuvant therapy for HCC resection have been reported., Although these two studies have an opposite conclusion, both of them did not include patients with macrovascular invasion, which is one of the indicators of advanced HCC. Conversely, other five cases reported in Japan utilized sorafenib as adjuvant management of surgery for HCC with macrovascular invasion., In those cases, surgical resection-based combination treatment provided long-time survival. However, because both of these reports come from Japan, we cannot get the English full text of them. To the best of our knowledge, this is the first case report of huge HCC with intrahepatic metastasis as well as macrovascular invasion in both portal vein and hepatic vein undergoing surgical resection and adjuvant MDT including sorafenib, TACE, and RFA.
Sorafenib is an oral multikinase inhibitor that has been proven to improve survival in patients with advanced HCC and extrahepatic spread or macrovascular invasion., Unfortunately, survival among these patients was modest, with the median overall survival of about 6 months in East Asian population.,, In contrast to sorafenib alone, either the combination of locoregional therapies or the combination of locoregional therapy with sorafenib has been reported with promising survival benefit for advanced HCC., Zhu et al. studied the efficacy of TACE combined with sorafenib in patients with HCC and PVTT. They found that combination therapy with TACE and sorafenib showed significant survival benefits compared with TACE alone. Liu et al. reported that the combination of RFA with TACE is better than TACE alone in treating advanced HCC. These studies suggest that combination therapies utilizing multimodal approaches may provide acceptable outcomes in advanced HCC patients. However, the optimal treatment for patients with HCC and intrahepatic metastasis as well as macrovascular invasion remains controversial.
Surgical resection with complete extirpation of tumor gives the best chance of a cure for patients with HCC. Owing to the improvement in surgical techniques and perioperative care, hepatectomy has become a reasonably safe treatment option with an acceptable mortality rate. Aggressive surgical resection for HCC with macrovascular invasion has been proposed from some centers with acceptable outcomes.,, In 2010, Shi et al. reported the median survival time of 78 HCC patients with mPVTT in their center was 10 months. What's more, Roayaie et al. reported a median survival time of 13 months in 165 HCC patients with mPVTT who were treated with surgical resection. On the other hand, Kokudo et al. retrospectively analyzed HCC patients with mHVTT or inferior vena cava tumor thrombus (IVCTT) in their center, and found that surgical resection, especially R0 resection, is associated with a good prognosis. Their data showed a median survival time of 3.95 years in mHVTT group and 1.39 years in IVCTT group. All these data suggest that surgical resection plus thrombectomy may offer a chance of long-time survival in HCC patients with macrovascular invasion.
In the present case, the patient was initially treated with TACE. However, after TACE, not only the tumor was not controlled, but also intrahepatic metastasis and mPVTT/mHVTT emerged. Under this condition, we performed surgical resection plus thrombectomy combined with administration of sorafenib, repeated TACE and RFA. The patient had been alive for 20 months after the treatment. Our case was consistent with the survival of patients treated with surgery mentioned above. Huge HCC with intrahepatic metastasis and mPVTT/mHVTT has been demonstrated to have higher incidence in tumor recurrence and mortality. The patient in our case has experienced tumor recurrence since the 2nd month after surgical resection. However, through treatment with sorafenib and locoregional therapies, the patient kept long-time survival with an ECOG performance status of zero. Besides, compared with the published literature [Table 1], our treatment strategy had a better outcome.,,, Thus, our case showed that the combination of surgery with the following sorafenib oral taking, TACE and RFA may result in an acceptable survival.

| > Conclusion|| |
We reported here a huge HCC case with intrahepatic metastasis, mPVTT, and mHVTT, who was treated with surgical resection-based MDT, achieved a relatively long-term survival. Further studies are needed to evaluate the benefits of this treatment strategy for HCC patients with intrahepatic metastasis, mPVTT, and mHVTT.
