HPB SURGERY. Contemporary Strategies in the Management of Hepatocellular Carcinoma

Shirin Elizabeth Khorsandi and Nigel Heaton

Liver transplantation is the treatment of choice for selected patients with hepatocellular carcinoma (HCC) on a background of chronic liver disease. Liver resection or locoregional ablative therapies may be indicated for patients with preserved synthetic function without significant portal hypertension. Milan criteria were introduced to select suitable patients for liver transplant with low risk of tumor recurrence and 5-year survival in excess of 70%. Currently the incidence of HCC is climbing rapidly and in a current climate of organ shortage has led to the re-evaluation of locoregional therapies and resectional surgery to manage the case load. The introduction of biological therapies has had a new dimension to care, adding to the complexities of multidisciplinary team working in the management of HCC. The aim of this paper is to give a brief overview of present day management strategies and decision making.

TRIALS. Transarterial RAdioembolization versus ChemoEmbolization for the treatment of hepatocellular carcinoma (TRACE): study protocol for a randomized controlled trial

Beatrijs A Seinstra, Luc Defreyne, Bieke Lambert, MarnixGEHH Lam, Helena M Verkooijen, Karel J van Erpecum, Bart van Hoek, Arian R van Erkel, Minneke J Coenraad, Imad Al Younis, Hans van Vlierberghe, and MauriceAAJ van den Bosch

Hepatocellular carcinoma is a primary malignant tumor of the liver that accounts for an important health problem worldwide. Only 10 to 15% of hepatocellular carcinoma patients are suitable candidates for treatment with curative intent, such as hepatic resection and liver transplantation. A majority of patients have locally advanced, liver restricted disease (Barcelona Clinic Liver Cancer (BCLC) staging system intermediate stage). Transarterial loco regional treatment modalities offer palliative treatment options for these patients; transarterial chemoembolization (TACE) is the current standard treatment. During TACE, a catheter is advanced into the branches of the hepatic artery supplying the tumor, and a combination of embolic material and chemotherapeutics is delivered through the catheter directly into the tumor. Yttrium-90 radioembolization (90Y-RE) involves the transarterial administration of minimally embolic microspheres loaded with Yttrium-90, a β-emitting isotope, delivering selective internal radiation to the tumor. 90Y-RE is increasingly used in clinical practice for treatment of intermediate stage hepatocellular carcinoma, but its efficacy has never been prospectively compared to that of the standard treatment (TACE). In this study, we describe the protocol of a multicenter randomized controlled trial aimed at comparing the effectiveness of TACE and 90Y-RE for treatment of patients with unresectable (BCLC intermediate stage) hepatocellular carcinoma.

INDIAN JOURNAL OF MEDICAL RESEARCH. Current status of multimodal & combination therapy for hepatocellular carcinoma

Jian Yang, Lunan Yan, and Wentao Wang

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. Surgery offers the only hope for cure. However, the potentially curable method is only possible for a small proportion of those afflicted, for the rest, palliative treatment is indicated. Despite all the treatment options when used as monotherapy, patients with HCC have a poor long term prognosis. In this setting, multimodal and combination therapy has emerged as an alternative treatment modality for HCC. Studies have looked at various forms of combination therapy, including neoadjuvant/adjuvant/downstaging therapy for surgery and the combined modality of non-operative therapies. The novel molecular targeted therapies are also being used as combination regimens for surgery or other non-operative therapies. Some forms of combination therapies, including downstaging therapy for surgery, salvage transplantation, and molecular targeted therapy have been shown to provide survival benefits for well selected patients, and need to be encouraged in the future. And others such as pre-operative bridging therapy for liver transplantation, adjuvant therapy for hepatic resection and combination of local and regional therapies have also shown some benefits in preliminary results, which need confirmation in further studies. In conclusion, multimodal and combination therapy is an encouraging treatment modality for HCC. Future research should continue to unravel the role of combination therapy with properly selected patients and appropriate end points.

WORLD JOURNAL OF GASTROENTEROLGY. Cerebral lipiodol embolism after transarterial chemoembolization for hepatic carcinoma: A case report

Zhong-Zhi Jia, Feng Tian and Guo-Min Jiang.

We report a case of cerebral lipiodol embolism (CLE) after transarterial chemoembolization (TACE) for unresectable hepatic carcinoma (HCC). A 54-year-old man with unresectable HCC underwent TACE via the right hepatic artery and right inferior phrenic artery using a mixture of 40 mg pirarubicin and 30 mL lipiodol. His level of consciousness deteriorated after TACE, and non-contrast computed tomography revealed a CLE. The cerebral conditions improved after supportive therapy. The complication might have been due to hepatic arterio-pulmonary vein shunt caused by direct invasion of the tumor. Even though CLE is an uncommon complication of TACE, we should be aware of these rare complications in patients with high risk factors.

ISRN GASTROENTEROLOGY. Transcatheter Arterial Chemoembolization: History for More than 30 Years

Yong-Song Guan, Qing He, and Ming-Quan Wang

Transcatheter arterial chemoembolization (TACE) is a minimally invasive technique to treat liver tumors, particularly hepatocellular carcinoma (HCC). TACE was used in early times to treat liver tumor patients with emergencies caused by symptomatic humoral hypercalcemia and develops gradually from the procedures of diagnostic angiography and transcatheter injection of agents and is in particular performed in the treatment of HCC. Since the beginning of this century, TACE has been used extensively in the palliative treatment of unresectable HCC. In recent years, it is indicated in selected patients with early-stage HCC. This review introduces the evolution of TACE for more than 30 years, its role in comprehensive treatment of HCC, the tendency of its refinement in future, and the combination use of TACE with other local ablative methods for the curative result of HCC.

INTERNATIONAL JOURNAL OF ONCOLOGY. First human study in treatment of unresectable liver metastases from colorectal cancer with irinotecan-loaded beads (DEBIRI)

K. Eichler, S. Zangos, M. G. Mack, R. Hammerstingl, T. Gruber-Rouh, C. Gallus, T. J. Vogl

The objective of this pilot clinical study was to assess the safety, technical feasibility, pharmacokinetic (PK) profile and tumour response of DC Bead™ with irinotecan (DEBIRI™) delivered by intra-arterial embolisation for the treatment of metastatic colorectal cancer. Eleven patients with unresectable liver metastases from CRC, tumour burden <30% of liver volume, adequate haematological, liver and renal function, performance status of <2 were included in this study. Patients received up to 4 sessions of TACE with DEBIRI at 3-week intervals. Feasibility of the procedure, safety and tumour response were assessed after each cycle. PK was measured after the first cycle. Patients were followed up to 24 weeks. Only mild to moderate adverse events were observed. DEBIRI is a technically feasibile procedure; no technical complications were observed. Average Cmax for irinotecan and SN-38 was 194 ng/ml and 16.7 ng/ml, respectively, with average t½ of 4.6 h and 12.4 h following administration of DEBIRI. Best overall response during the study showed disease control in 9 patients (2 patients with partial response and 7 with stable disease, overall response rate of 18%). Our study shows that transarterial chemoembolisation with irinotecan-loaded DC beads (DEBIRI) is safe, technically feasible and effective with a good PK profile.

BIOLOGIST. Hepatocellular carcinoma: natural history, current management, and emerging tools

Christopher L Tinkle and Daphne Haas-Kogan

Hepatocellular carcinoma (HCC) is the most common primary liver tumor and represents the third-leading cause of cancer-related death in the world. The incidence of HCC continues to increase worldwide, with a unique geographic, age, and sex distribution. The most important risk factor associated with HCC is liver cirrhosis, with the majority of cases caused by chronic infection with hepatitis B (HBV) and C (HCV) viruses and alcohol abuse, although nonalcoholic fatty liver disease is emerging as an increasingly important cause. Primary prevention in the form of HBV vaccination has led to a significant decrease in HBV-related HCC, and initiation of antiviral therapy appears to reduce the incidence of HCC in patients with chronic HBV or HCV infection. Additionally, the use of ultrasonography enables the early detection of small liver tumors and forms the backbone of recommended surveillance programs for patients at high risk for the development of HCC. Cross-sectional imaging studies, including computed tomography and magnetic resonance imaging, represent further noninvasive techniques that are increasingly employed to diagnose HCC in patients with cirrhosis. The mainstay of potentially curative therapy includes surgery – either resection or liver transplantation. However, most patients are ineligible for surgery, because of either advanced disease or underlying liver dysfunction, and are managed with locoregional and/or systemic therapies. Randomized controlled trials have demonstrated a survival benefit with both local therapies, either ablation or embolization, and systemic therapy in the form of the multikinase inhibitor sorafenib. Despite this, median survival remains poor and recurrence rates significant. Further advances in our understanding of the molecular pathogenesis of HCC hold promise in improving the diagnosis and treatment of this highly lethal cancer.

INTERNATIONAL JOURNAL OF HEPATOLOGY. Milan Criteria and UCSF Criteria: A Preliminary Comparative Study of Liver Transplantation Outcomes in the United States

Supriya S. Patel, Amanda K. Arrington, Shaun McKenzie, Brian Mailey, Michelle Ding, Wendy Lee, Avo Artinyan, Nicholas Nissen, Steven D. Colquhoun, and Joseph Kim

The application of orthotopic liver transplantation (OLT) for patients with hepatocellular cancer (HCC) necessitates highly selective criteria to maximize survival and to optimize allocation of a scarce resource. The objective of this study was to compare the outcomes of OLT for HCC in patients transplanted under Milan and UCSF criteria. The United Network of Organ Sharing (UNOS) database was queried for patients who had undergone OLT for HCC from 2002 to 2007, and 1,972 patients (Milan criteria, ; UCSF criteria, ) were identified. Patients were stratified by pretransplant criteria (Milan versus UCSF), and clinical and pathologic factors and overall survival were compared. There were no differences in age, gender, diabetes mellitus, body mass index, and hepatitis B, or C status between the two groups. Overall survival was similar between the Milan and UCSF cohorts (1-, 2-, 3-, and 4-year survival rates: 88%, 81%, 76%, and 72% versus 91%, 80%, 68% and 51%, respectively, ). Although the number of patients within UCSF criteria was small, our results nevertheless suggest that patients with HCC may have equivalent survival when transplanted under Milan and UCSF criteria. Long-term followup may better determine whether UCSF criteria should be widely adopted.

BMC CANCER. The efficacy of TACE combined sorafenib in advanced stages hepatocellullar carcinoma

Xu-Dong Qu, Cheng-Shi Chen, Jian-Hua Wang, Zhi-ping Yan, Jie-min Chen, Gao-quan Gong, Qin-xin Liu, Jian-jun Luo, Lin-xiao Liu,1 Rong Liu, and Sheng Qian

Background: The long-term survival in hepatocellullar carcinoma (HCC) patients after transarterial chemoembolization (TACE) remains dismal due to local and/or regional recurrence as well as distant metastasis. The efficacy of sorafenib in advanced HCC has been demonstrated and brought great hope. Recently, the use of sorafenib in combination with TACE for BCLC stage B and C HCC patients was recommended. However, data on this dual-modality treatment is little, and its advantage over TACE alone has not been addressed. The present study sought to understand the efficacy of the combination of TACE and sorafenib in the treatment of advanced HCC.

THE SCIENTIFIC WORLD JOURNAL. Quantitative Portal Vein Velocity of Liver Cancer Patients with Transcatheter Arterial Chemoembolization on Angiography

Yung-Jen Ho, Mu-Bai Chang, Yang-Hsien Lin, Chun-Hsu Yao, and Tzung-Chi Huang

Objective. We applied optical flow method (OFM) to quantify relative velocities of blood flow using digital subtraction angiography (DSA) in the vascular analysis of hepatocellular carcinoma (HCC) patients who underwent transarterial chemoembolization (TACE) treatment. Methods. A total of 40 HCC patients treated by TACE were analyzed in this study. DSA imaging with a 12-inch field of view, 1024 × 1024 pixels and 4 frames/second was acquired. OFM developed for motion estimation is applied for blood flow estimation. Two acrylic phantoms were built to validate the method. Results. The relationship between the OFM and Doppler measurements was found linear with 𝑅 2 = 0 . 9 9 for both straight and curved tube phantoms. Quantitative blood flow distribution images of the portal vein region were presented. After TACE, the minimum, maximum and mean velocities in the portal vein all decreased ( 𝑃 < 0 . 0 5 ). Additionally, the velocity in the portal vein is significantly lower with a higher Child-Pugh score ( 𝑃 < 0 . 0 1 ). Conclusions. The present technique provides add-on quantitative information of flows to DSA and the hemodynamic analysis in relative quantifications of blood flow in portal vein of hepatocellular carcinoma patients using DSA.
