ABSTRACT For decision of adequate surgical therapy and comparison of results differentiation of hepatocellular carcinomas (HCC) in cirrhotic and noncirrhotic livers is important. Liver resection is the treatment of choice for HCC in noncirrhotic liver. Between 4/94 and 8/99 we treated 54 patients with hepatocellular carcinoma (HCC) by subtotal hepatic resection (n = 40) and orthotopic liver transplantation (n = 14). Overall 1- and 3-year survival rates of the resection group were 45 and 25% (median follow up: 3.5 years). One-year survival in the transplantation group was 72% (median follow up: 2.2 years). In patients with HCC in cirrhosis in UICC stage I to III the optimal therapy is a controversial issue. In these patients the results after liver resection are poor due to high operative mortality and recurrence (3-year recurrence-free survival: 30%). Regarding the literature, liver transplantation is the treatment of choice in small (< 3-5 cm, < or = 2 tumors) HCCs arising in cirrhosis with better outcome compared to resection. The data in the literature report 3-year-survival rates after liver transplantation of 60-80%. However, consequent patient selection is necessary for this treatment modality. Due to the limited donor resources liver transplantation is rarely justified in advanced tumors.

    ABSTRACT: This study aims to analyze the outcomes of patients with Child-Pugh A class cirrhosis and a single hepatocellular carcinoma (HCC) up to 5 cm in diameter who underwent liver transplantation vs. resection. During 2007 to 2012, 282 Child-Pugh A cirrhotic patients with a single HCC up to 5 cm in diameter either underwent liver resection (N = 243) or received liver transplantation (N = 39) at our center. Patient and tumor characteristics and outcomes were analyzed. Patients who underwent liver transplantation had a better recurrence-free survival (RFS) vs. those who underwent liver resection. However, the 5-year survival rates after these two treatments were comparable. Similar results were observed when we analyzed patients with a HCC less than 3 cm, and for patients with portal hypertension. In the multivariate analysis, tumor differentiation, difference of primary treatment, and presence of microvascular invasion were associated with postoperative recurrence. However, only differentiation negatively impacted overall survival after operation. Although more recurrences were observed in Child A cirrhotic patients with a single HCC up to 5 cm after liver resection, liver resection offers a similar 5-year survival to liver transplantation, even for patients with portal hypertension.

    ABSTRACT: Surgical resection is not indicated in patients with portal hypertension in the current guideline of Barcelona Clinic Liver Cancer (BCLC) stage. We report a systematic review and meta-analysis to determine the impact of clinically significant portal hypertension on survival in patients with hepatocellular carcinoma (HCC) following hepatectomy. Searched data in PubMed, EMBASE, and the Cochrane Library were reviewed and 11 publications were included in the meta-analysis. The inclusion criteria of clinically significant portal hypertension were esophageal varices and/or thrombocytopenia with splenomegaly. Pooled data were extracted and computed into odds ratios (ORs) for clinical outcome and hazard ratios (HRs) for overall survival. The final pooled data were composed of 2,285 patients. There were 775 patients with clinically significant portal hypertension (PHT group) and 1,510 patients without clinically significant portal hypertension (non-PHT group). Pooled proportion of mortality was 6.1% (95% confidence interval [CI] 0.032-0.116) in PHT group and 2.8% (95% CI 0.014-0.054) in the non-PHT group. The pooled proportion of morbidity was 41.7% (95% CI 0.274-0.575) in PHT group and 34.7% (95% CI 0.243-0.467) in non-PHT group. Pooled data confirmed a significantly higher postoperative mortality in the PHT group, with OR 3.02 (P < 0.001). The PHT group also demonstrated significantly higher occurrence of postoperative complications (OR 1.39, P = 0.008), liver-related morbidity (OR 3.10, P < 0.00001), and liver failure (OR 2.14, P = 0.0005) compared to the non-PHT group. According to the overall survival, pooled analysis demonstrated that the PHT group demonstrated poorer survival than the non-PHT group (HR 1.48, P = 0.007). The analyses support significantly higher rates of postoperative mortality, complications, liver-related morbidity, liver failure, and poorer overall survival in PHT group compared with the non-PHT group. Surgical resection should be selected carefully with strict surgical strategy in patients with clinically significant portal hypertension when surgical resection is planned.

    ABSTRACT: As the leading cause of disease-related deaths, cancer is a major public health threat worldwide. Surgical resection is still the first-line therapy for patients with early-stage cancers. However, postoperative relapse and metastasis remain the cause of 90% of deaths of patients with solid organ malignancies, including hepatocellular carcinoma (HCC). With the rapid development of molecular biology techniques in recent years, molecularly targeted therapies using monoclonal antibodies, small molecules, and vaccines have become a milestone in cancer therapeutic by significantly improving the survival of cancer patients, and have opened a window of hope for patients with advanced cancer. Hypervascularization is a major characteristic of HCC. It has been reported that anti-angiogenic treatments, which inhibit blood vessel formation, are highly effective for treating HCC. However, the efficacy and safety of anti-angiogenesis therapies remain controversial. Sorafenib is an oral multikinase inhibitor with anti-proliferative and anti-angiogenic effects and is the first molecular target drug approved for the treatment of advanced HCC. While sorafenib has shown promising therapeutic effects, substantial evidence of primary and acquired resistance to sorafenib has been reported. Numerous clinical trials have been conducted to evaluate a large number of molecularly targeted drugs for treating HCC, but most drugs exhibited less efficacy and/or higher toxicity compared to sorafenib. Therefore, understanding the mechanism(s) underlying sorafenib resistance of cancer cells is highlighted for efficiently treating HCC. This concise review aims to provide an overview of anti-angiogenesis therapy in the management of HCC and to discuss the common mechanisms of resistance to anti-angiogenesis therapies.
