RFA is a safe and effective treatment of small HCC in cirrhotics awaiting OLT, although tumor size (>3 cm) and time from treatment (>1 year) predict a high risk of tumor persistence in the targeted nodule. RFA should not be considered an independent therapy for HCC.

Yttrium-90 radioembolization (Y90RE) is a novel approach to radiation therapy for hepatocellular carcinoma (HCC), never tested in phase 2 studies. Fifty-two patients with intermediate (n.17) to advanced (n.35) HCC were prospectively recruited to assess, as the primary endpoint, efficacy of Y90RE on time-to-progression (TTP). Secondary endpoints were tumor response, safety, and overall survival (OS). All patients were Eastern Cooperative Oncology Group (ECOG) score 0-1, Child-Pugh class A-B7. Y90RE treatments aimed at a lobar delivery of 120 Gy. Retrospective dosimetric correlations were conducted and related to response. Fifty-eight treatments were performed on 52 patients. The median follow-up was 36 months. The median TTP was 11 months with no significant difference between portal vein thrombosis (PVT) versus no PVT (7 versus 13 months). The median OS was 15 months (95% confidence interval [CI], 12-18 months) with a nonsignificant trend in favor of non-PVT versus PVT patients (18 versus 13 months). Five complete responses occurred (9.6%), and the 2 year-progression rate was 62%. Objective response was 40.4%, whereas the disease control rate (78.8%) significantly affected survival (responders versus nonresponders: 18.4% versus 9.1%; P 5 0.009). Tumor response significantly correlated with absorbed dose in target lesions (r 5 0.60, 95% CI, 0.41-0.74, P < 0.001) and a threshold of 500 Gy predicted response (area under the curve, 0.78). Mortality at 30-90 days was 0%-3.8%. Various grades of reduction in liver function occurred within 6 months in 36.5% of patients, with no differences among stages. On multivariate analysis, tumor response was the sole variable affecting TTP (P < 0.001) and the second affecting survival (after Child-Pugh class). Conclusion: Y90RE is an effective treatment in intermediate to advanced HCC, particularly in the case of PVT. Further prospective evaluations comparing Y90RE with conventional treatments are warranted.

. The primary end point was recurrence-free survival (RFS); secondary end points were disease-specific and overall survival. Intention-to-treat and subgroup analysis on adherent patients were conducted. Treatment effects on early/late recurrences were assessed using multiple Cox regression analysis. No patient experienced life-threatening adverse events. There were 28 adherent patients (37%). After 45 months of median follow-up, overall survival was 58.5%, and no significant difference in RFS was detectable between the two study arms (24.3% vs. 5.8%; P ‫؍‬ .49). HCC recurred in 100 patients (48 IFN-treated, 52 controls), with a 50% reduction in late recurrence rate in the treatment arm. HCC multiplicity and vascular invasion were significantly related to recurrence (P ‫؍‬ .01 and .0003). After viral status stratification, while no treatment effect was apparent in the mixed HCV؉HBV population and on early recurrences (72 events), there was a significant benefit on late recurrences (28 events) in HCV-pure patients adherent to treatment (HR: 0.3; 95% CI: 0.09-0.9; P ‫؍‬ .04). In conclusion, IFN does not affect overall prevention of HCC recurrence after resection, but it may reduce late recurrence in HCV-pure patients receiving effective treatment.

A dosimetric treatment planning criterion for Child A patients without complete obstruction of the portal vein was developed.

Diabetes mellitus frequently complicates cirrhosis but the pathogenic mechanisms are unknown. To assess the contribution of reduced insulin action and secretion, 24 cirrhotic-diabetic patients waiting for liver transplant because of an unresectable hepatocarcinoma underwent an oral glucose tolerance test (OGTT) to assess the ␤-cell function and an insulin clamp combined with [3-3 H]glucose infusion to measure whole body glucose metabolism before and 2 years after the transplant. Seven cirrhotic nondiabetic patients, 11 patients with chronic uveitis on similar immunosuppressive therapy, and 7 healthy subjects served as control groups. Cirrhotic patients showed a profound insulin resistance, and diabetics in addition also showed increased endogenous glucose production (P Ͻ .05) and insulin deficiency during the OGTT (P Ͻ .05). Liver transplantation normalized endogenous glucose production and insulin sensitivity but failed to cure diabetes in 8 of the 24 patients because a markedly low insulin response during the OGTT. Age, body mass index, family history of diabetes, immunosuppressive drugs, and pathogenesis of cirrhosis did not predict in whom liver transplant was going to cure diabetes. On the contrary, a reduced secretory response characterized the patients in whom the transplant would not be curative. In summary, insulin resistance was a primary event complicating cirrhosis but additional ␤-cell secretory defects were crucial for development of diabetes. Liver transplantation, lessening insulin resistance, cured hepatogenous diabetes in 67% of cirrhotic-diabetic patients; nevertheless 33% were still diabetics because the persistence of a reduced ␤-cell function, which makes these patients eventually eligible for combined islet transplantation. (HEPATOLOGY 2000;31:694-703.)Cirrhotic patients are characterized by impaired glucose metabolism 1 ; 60% to 80% are glucose intolerant and 10% to 15% develop overt diabetes mellitus. [2][3][4] The development of diabetes following liver cirrhosis seems also to be relatively rapid; during a period of 5 years nearly 15% to 20% of cirrhotic patients develop frank hyperglycemia. 5 The high incidence of diabetes among cirrhotic patients was recognized to be secondary to the hepatic disease since 1906 when the term ''hepatogenous diabetes'' was first coined. 6 Diabetes does not affect short-term survival, but it seems to be significantly correlated with poor prognosis in long-term follow-up, the higher mortality rate being mainly caused by an increased risk of hepatocellular failure. 7 The sequence, the relative importance, and the molecular mechanisms of the pathogenic factors are still largely unknown because liver cirrhosis is characterized by heterogeneous clinical pictures related to etiologic and environmental factors, nutritional state, complex physiologic endocrine interactions, and stage and stability of the liver disease. Recently liver transplantation was found to be an effective treatment for small unresectable hepatocellular carcinomas in patients with cirrhosis,...
