Background/aims: Evaluation of the short- and long-term outcome of liver resections for HCC in cirrhotic patients., Methodology: A retrospective analysis was performed on 106 consecutive cirrhotic patients with HCC resected between June 1974 and September 2002. Univariate and multivariate analyses were performed on several clinicopathological variables to analyze factors affecting the long-term outcome and intrahepatic recurrence., Results: Overall mortality and morbidity were 10.7% and 26% respectively. These rates significantly decreased in the last years: from 1997 to 2002 no hospital mortality has been recorded. After a median follow-up of 19 months (interquartile range: 10-36), tumor recurrence appeared in 25 patients (23.5%). The 1-, 3-, and 5-year overall survival rates were 86.6%, 70.3%, and 60.6%, respectively. The 1-, 3-, and 5-year disease-free survival rates were 86.3%, 58.1%, and 40.7%. Univariate analysis showed that viral etiology of cirrhosis (p=0.03), presence of multiple nodules (p=0.02) and vascular invasion (p=0.05) are related to a worse long-term survival. Multivariate analysis showed that only the viral etiology of cirrhosis and the presence of multiple nodules were significant independent prognostic factors., Conclusions: Results after hepatic resection for HCC in cirrhotic patients can be improved by using a limited surgical approach. The viral etiology of cirrhosis, the presence of multiple nodules and vascular invasion negatively affected recurrence rate and long-term survival.

Aims: To compare the prognostic efficacy of the 5th and 6th edition of the TNM staging system for HCC., Methods: We retrospectively applied the old and the new systems to 393 resected patients, comparing the efficacy of both in prognostic evaluation., Results: The 1-, 3- and 5-year overall survival rates were 89.7, 71.1 and 56.3%, respectively. The 1-, 3- and 5-year disease-free survival rates were 79.4, 54.6 and 39.4%, respectively. Among the factors evaluated, Child's grade B and C (p=0.001) and presence of multiple nodules (p=0.01) were found to be related either to a worse long-term survival or to a worse disease-free survival. Stratifying patient survivals according to the old TNM system, we found significant differences only between stages II and IIIA (p=0.001); otherwise stages I and II (p=0.9) as well as stages IIIA and IVA (p=0.9) showed similar survival rates. Analysing the new TNM system, we found a more homogeneous staging stratification, with significant differences both between stage I and II (p=0.02) and between stage II and IIIA (p=0.05)., Conclusions: In the present multicentric study, long term overall and disease-free survival after liver resection for HCC was strongly affected by the number of tumours and the underlying liver disease. Our results suggest that the new classification appears to achieve an accurate stratification of patients, simpler than the previous edition, as well as a more reliable comparative analysis of outcome after hepatic resection for HCC.

To evaluate the short and long term outcome of liver resections for hepatocellular carcinoma in cirrhotic patients. A retrospective analysis was performed on 106 consecutive cirrhotic patients with hepatocellular carcinoma resected between June 1974 and September 2002 at the Department of Surgery "Pietro Valdoni" - University of Rome "La Sapienza" and at the Liver and Multivisceral Transplant Unit of the University of Modena. Univariate and multivariate analyses were performed on several clinicopathological variables to analyze factors affecting the long-term outcome and intrahepatic recurrence. Overall mortality and morbidity were 10.7% and 26% respectively. These rates significantly decreased in the last years: from 1997 to 2002 no hospital mortality has been recorded. After a median follow-up of 19 months (interquartile range: 10-36), tumour recurrence appeared in 25 patients (23,5%). The 1-, 3-, and 5-year overall survival rates were 86,6%, 70,3%, and 60,6%, respectively. The 1-, 3-, and 5-year disease-free survival rates were 86,3%, 58,1%, and 40,7%. On univariate analysis, viral ethiology of cirrhosis (p=0.03), presence of multiple nodules (p=0.02) and vascular invasion (p=0.05) were found to be related to a worse long-term survival. At the multivariate analysis only the viral ethiology of cirrhosis and the presence of multiple nodules were confirmed as indipendent prognostic factors. Early results after hepatic resection for HCC can be improved by using a limited surgical approach. The viral ethiology of cirrhosis, the presence of multiple nodules and vascular invasion negatively affected recurrence rate and long-term survival.

Background: Due to the longer life expectancy of the world's population, the number of elderly cirrhotic patients undergoing surgery for hepatocellular carcinoma (HCC) is increasing. Our study evaluates the benefits of hepatic resections for HCC in cirrhotic patients aged over 65, analysing the early and long-term surgical results., Patients and Methods: We retrospectively considered a series of 46 patients receiving hepatic resection for HCC. The clinicopathological data and surgical outcome of 14 (30.4%) patients aged 65 or older (group I) were evaluated and compared to the 32 (69.6%) younger than 65 (group II)., Results: No operative mortality was recorded in either group. The hospital mortality rate was 7.1% (1 out of 14) in group I and 9.4% (3 out of 32) in group II (p = 1.00). Hospital morbidity did not differ significantly in the two groups (21.4% vs 34.4%; p = 0.50). At follow-up (median 34 months, interquartile range: 12-63) 3 patients from group I (21.4%) and 16 patients from group II (50%) experienced tumor recurrence (p = 0.14). The five-year disease-free survival rate for group I and group II was 71.4% vs 28.2%, respectively (p = 0.05). The overall 5-year survival rate for group I and group II was, respectively, 77.4% vs 41.8%, (p = 0.3)., Conclusion: Elderly cirrhotic patients with HCC can benefit from hepatic resection as well as younger patients; age by itself should not be considered a contraindication to surgery.

Starting from biochemical hypotheses on hepatic encephalopathy, which presuppose at the basis of this disease first of all some modifications of the plasmatic values of octopamine, ammonia, serotonin and of particular aromatic aminoacids, the Authors compared the levels of ammoniemia and of octopaminemia with eegraphic data, in two groups of cirrhotic patients, operated of porto-cava anastomosis (16 patients) ad of mesenterico-cava by-pass (24 patients). All this in order to value if there are significant correlations between these values and the cerebral damage and also if there are differences between the two types of operation. Attained data show a good correlation between neuropsychiatric symptomatology and importance of the cerebral damage noticeable at the E.E.G. As to the possible correlations existing between biochemical data and E.E.G., while as to plasmatic octopamine no significant modifications were found, as to ammoniemia, highest values correspond to findings of greater cerebral compromission. Moreover, it seems that between the two types of operations, the mesenterico-cava by-pass is the one that allows a better clinical and eegraphic evolution.

Recurrent episodes of hepatic encephalopathy (HE) frequently occur in surgically shunted cirrhotic patients. The prevention of these episodes is based mainly on the long-term use of lactulose. Recently, lactitol, a nonabsorbable disaccharide similar to lactulose, has been proposed as an alternative in the management of HE. It has the advantage of being better tolerated and producing a more predictable catharsis. The effects of the two agents were compared in a controlled randomized study lasting six months involving 31 cirrhotic patients with portal-systemic shunt, of whom 40% experienced HE. The PSE index (mental state, EEG, asterixis, Raitan test, and ammonia) was assessed in each patient on entry to the study and every three months during treatment. Episodes of HE, side effects, and the patients' comments on efficacy, tolerability, and palatability were recorded. The dose required to induce two bowel movements per day was 48 +/- 25 ml of lactulose syrup and 36 +/- 7 g of lactitol. During the study, the number of patients who had an episode of HE and the PSE index was similar in both groups. The patients judged lactitol better from the point of view of palatability. Meteorism and flatulence, experienced by patients treated with lactulose, was not reported by the lactitol group. We concluded that lactitol is as effective as lactulose in the long-term prevention of episodes of HE in cirrhotics with portal-systemic shunt and may be better tolerated.
