Hepatocellular carcinoma (HCC) is one of the most common solid malignancies worldwide, and its incidence is dramatically increasing in the United States. Unlike many other malignancies, treatment of HCC often involves management of two disease processes: liver cancer and cirrhosis. In addition to tumor-specific factors such as tumor size, number, and location, the surgeon also has to consider liver specific factors such as degree of fibrosis/ cirrhosis, extent of portal hypertension, and the size of the future liver remnant. As such, therapy for HCC is complex and can involve resection, transplantation, interventional radiology-based liver-directed therapies, and emerging systemic chemotherapeutic and targeted agents. To successfully treat this group of patients, surgical oncologists should be aware of the many and varied approaches to treating patients with HCC. Specifically, surgical oncologists need to know not only how to select patients and perform hepatic resection in appropriate patients with HCC, but also be familiar with the controversy surrounding management of early HCC and identify those factors that may make one therapeutic modality preferable compared with others. In addition, surgical oncologists need to be familiar with the role of intra-arterial regional therapy as "destination" therapy for unresectable HCC, as well as bridge therapy before transplantation/resection. Finally, surgical oncologists need to be aware of the emerging role of systemic chemotherapy for stage IV HCC, as well as its potential future role as adjuvant therapy. In this issue of Annals of Surgical Oncology, a series of review articles have been solicited to provide evidence-based data to equip the practicing surgical oncologist with the knowledge to understand these complex treatment issues.

Background: The treatment of hepatocellular carcinoma (HCC) is challenging, but transplantation of the liver has emerged as one of the options in the therapeutic armamentarium against this disease. Methods: This article reviews the changing criteria for patient eligibility for liver transplantation for HCC and presents an initial evaluation of institutional treatment outcomes for this treatment modality. A method for evaluating prognosis is also described. Results: Patients are considered for liver transplantation if they meet the Milan criteria for eligibility or a UCSF-attributed expansion of these criteria that includes the "rule of 7," whereby the sum of the size of the largest nodule plus the total number of nodules cannot exceed 7. Preliminary institutional experience suggests a tumor recurrence rate of 11% in 91 patients with HCC who received liver transplants between 1996 and 2008. Conclusions: Liver transplantation offers an opportunity for long-term survival in patients with HCC and chronic cirrhosis whose tumor cannot be resected. Criteria for patient selection for this modality of treatment continue to be upgraded and refined.

The NF-kappa B activating kinase IKK beta suppresses early chemically induced liver tumorigenesis by inhibiting hepatocyte death and compensatory IKK beta's role in late tumor promotion and progression, we developed a transplant system that allows initiated mouse hepatocytes to form hepatocellular carcinomas (HCC) in host liver after along latency. Deletion of IKK beta long after initiation accelerated HCC development and enhanced proliferation of tumor initiating cells. These effects of IKK beta/NF-kappa B were cell autonomous and correlated with increased accumulation of reactive oxygen species that led to JNK and STAT3 activation. Hepatocyte-specific STAT3 ablation prevented HCC development. The negative crosstalk between NF-kappa B and STAT3, which is also evident in human HCC, is a critical regulator of liver cancer development and progression.

Recurrent chromosomal aberrations are often observed in hepatocellular carcinoma (HCC), but little is known about the functional non-coding sequences, particularly microRNAs (miRNAs), at the chromosomal breakpoints in HCC. Here we show that 22 miRNAs are often amplified or deleted in HCC. MicroRNA-151 (miR-151), a frequently amplified miRNA on 8q24.3, is correlated with intrahepatic metastasis of HCC. We further show that miR-151, which is often expressed together with its host gene FAK, encoding focal adhesion kinase, significantly increases HCC cell migration and invasion in vitro and in vivo, mainly through miR-151-5p, but not through miR-151-3p. Moreover, miR-151 exerts this function by directly targeting RhoGDIA, a putative metastasis suppressor in HCC, thus leading to the activation of Rac1, Cdc42 and Rho GTPases. In addition, miR-151 can function synergistically with FAK to enhance HCC cell motility and spreading. Thus, our findings indicate that chromosome gain of miR-151 is a crucial stimulus for tumour invasion and metastasis of HCC.

Postoperative recurrence of hepatocellular carcinoma (HCC) is a major problem after surgical resection. To date, adjuvant chemotherapy or other adjuvant modalities have not been proven effective in preventing or delaying recurrence. The aim of this prospective randomized study was to evaluate the effectiveness of capecitabine as a postoperative adjuvant regimen in inhibiting the recurrence of HCC. Between August 2003 and January 2005, 60 HCC patients who underwent curative resection were randomized into a capecitabine (n = 30) or a control (n = 30) group. The capecitabine group received 4-6 episodes of capecitabine treatment plus routine supportive care. Each episode consisted of 2 weeks of capecitabine followed by 1-week rest. The control group received routine supportive care only. The follow-up was 4-65 months (median: 47.5 months). Cancer recurred in 16 patients (53.3%) in the capecitabine group and in 23 patients (76.7%) in the control group. The median time to recurrence (TTR) was 40.0 months (95% confidence interval [95% CI], 31.0-49.2 months) and 20.0 months (95% CI, 12.8-27.2 months) in the capecitabine and control groups, respectively (P = 0.046). The 5-year overall survival rate was 62.5% and 39.8% in the capecitabine group and control group, respectively (P = .216). Adverse reactions to capecitabine were generally mild and included nausea, vomiting, diarrhea, and decreased white blood cell and/or platelet counts. Postoperative adjuvant therapy with capecitabine is well tolerated, postpones the recurrence of HCC, and reduces the risk of tumor recurrence. In addition, it is likely to improve postoperative survival.

BACKGROUND: Since March 2002, the United Network for Organ Sharing liver allocation policy has given extra priority to patients with hepatocellular carcinoma (HCC) who meet specific medical criteria. This study reviews our experience with liver transplantation for HCC under this system. STUDY DESIGN: Between March 2002 and April 2009, 244 patients with HCC underwent primary liver or liver-kidney transplantation under the current allocation system at the University of Miami. Outcomes including HCC recurrence-free survival (RFS) and patient survival (PS) were assessed retrospectively. Clinical variables that predicted outcomes were analyzed. RESULTS: The median time from listing to transplantation was 48 days. The median follow-up was 27.4 months, with an observed recurrence rate of 10.7%. The RFS rates at 1, 3, and 5 years after transplantation were 96.0%, 89.0%, and 83.6%, respectively. The PS rates at 1, 3, and 5 years after transplantation were 86.3%, 71.5%, and 61.7%, respectively. Among patients diagnosed with T2 HCC, a trend toward improved RFS was observed for those who received preoperative ablative therapy;PS was similar (p > 0.05). Outcomes (RFS and PS) for patients with T3 HCC were similar to those in patients with T2 HCC (p > 0.05). Patients with an alpha-fetoprotein >100 ng/mL had all RFS that was inferior to that in patients with an alpha-fetoprotein <= 100 ng/mL (p < 0.0001). CONCLUSIONS: Under the current allocation system, transplantation for HCC results in excellent RFS;PS depends Oil factors other than HCC;the value of preoperative ablative therapy for patients with T2 HCC is uncertain;the current criteria could be expanded to include selected patients with T3 HCC;and an elevated AFP level is associated with an increased risk of HCC recurrence after transplantation.

Hepatectomy is the principal treatment for hepatocellular carcinoma (HCC); however, some HCCs are not resectable by conventional hepatic resection. In such apparently incurable cases, extracorporeal hepatic resection (ECHR) may offer an option for survival.1 We recently encountered a juvenile patient with faradvanced HCC who was successfully treated by ECHR with favorable long-term survival.

Thrombomodulin (TM) is a key molecule mediating circulation homeostasis through its binding to thrombin. The TM-thrombin complex can activate protein C and thrombin-activatable fibrinolysis inhibitor to form a tight clot. In many cancer tissues, decrease of TM expression may correlate with cancer metastasis. However, the role of TM in hepatocellular carcinoma (HCC) progression is still unclear. We characterized TM expression in HCC cells (HepJ5 and skHep-1 cells) using real-time polymerase chain reaction (PCR) and Western blotting. We then manipulated TM expression using both TM-specific short hairpin RNA (shRNA) and overexpressing it in HCC cells. Transwell migration assay was performed to monitor the migratory ability of HCC cells under different levels of TM expression. We found that TM was ectopically highly expressed in skHep-1 at both transcriptional and translational levels. After silencing TM expression in skHep-1 cells, we found that metastatic capability was dramatically increased. Conversely, overexpression of TM in HepJ5 cells decreased metastatic ability. We investigated the possible mechanism and found that decreased TM-mediated enhancement of cell migration was dependent on upregulation of ZEB1, a repressor of E-cadherin. TM may be a modulator of cancer metastasis in HCC. Downregulation of TM expression may increase ZEB1 and decrease E-cadherin levels.

The incidence of hepatocellular carcinoma (HCC) continues to rise worldwide, and this is related primarily to the prevalence of viral hepatitis.1 Even though the majority of patients with HCC present too late in the course of the disease to be considered for anything other than medical/palliative therapy, there remains a small group of patients who are candidates for potentially curative therapy [liver transplantation (LT), liver resection, or cytoreductive therapy]. Fortunately, there is no absolute resource barrier to liver resection or cytoreductive therapies; however, the same is not true for LT.

Hepatocellular carcinoma (HCC) is a global health problem, although developing countries are disproportionally affected: over 80% of HCCs occur in such regions. About three-quarters of HCCs are attributed to chronic HBV and HCV infections. In areas endemic for HCV and HBV, viral transmission occurs at an early age, and infected individuals develop HCC in mid-adulthood. As these are their most productive years of life, HCC accounts for a substantial burden on the health-care system and drain of productive capacity in the low-income and middle-income countries most affected by HCV and HBV infections. Environments with disparate resource levels require different strategies for the optimal management of HCC. In high-resource environments, guidelines from the American Association for the Study of Liver Diseases or European Association for the Study of the Liver should be applied. In intermediate-resource or low-resource environments, the fundamental focus should be on primary prevention of HCC, through universal HBV vaccination, taking appropriate precautions and antiviral treatments. In intermediate-resource and low-resource environments, the infrastructure and capacity for abdominal ultrasonography, percutaneous ethanol injection, radiofrequency ablation and surgical resection should be established. Programs to provide targeted therapy at low cost, similar to the approach used for HIV therapy in the developing world, should be pursued.
