Objective:To determine the long-term results of liver transplantation for well- or moderately differentiated hepatocellular carcinoma (HCC). Summary Background Data:HCC patient selection for liver transplantation remains controversial, and deciding exclusively on the strength of criteria such as number and size of nodules appears prognostically inaccurate. Methods:Since 1991, preoperative tumor grading has been used at our center to establish whether a patient with HCC is fit for transplantation. Poorly differentiated HCC cases were excluded, while size and number of nodules were not considered as absolute selection criteria. Thirty-three patients with moderately or well-differentiated HCC were prospectively studied after liver transplantation. A group of 15 patients with incidental HCC transplanted during the same period were also evaluated and compared with the 33 patients with preoperatively diagnosed HCC. Results:On histologic examination, 38% of the entire group of 48 patients did not meet the “Milan criteria” and 42% were pTNM stages III and IV. The median follow-up was 44 months. The 5-year actuarial survival rate was 75% and recurrence-free survival was 92%. HCC recurred in only 3 patients (6%). The only histomorphologic variable differing significantly between incidental and nonincidental HCC was nodule size. The timing of diagnosis (incidental vs. nonincidental HCC), the Milan criteria, and the TNM stage revealed no statistically significant impact on overall and recurrence-free survival rates. Conclusions:The routine pre-orthotopic liver transplantation tumor grading may represent a valid tool in the selection of unresectable HCC patients for transplantation.

The GH-related effects are primarily mediated by insulin-like growth factor I (IGF-I), a peptide hormone almost completely produced by the liver. Liver cirrhosis is usually accompanied by a fall in protein turnover. Furthermore, an important consequence of chronic liver disease (CLD) is growth hormone/insulin-like growth factor (GH/IGF) axis modification and growth failure. Nutritional status also suffers in this condition, and IGF-I has been proposed as a marker of hepatocellular dysfunction, malnutrition and survival. CLD is characterised by alterations of various clinical biochemistry laboratory parameters. Aminotransferases, bilirubin, plasma proteins, together with prothrombin time and gamma globulins, are usually examined for laboratory diagnostic and/or monitoring purposes. These traditional parameters are also used in the perioperative liver transplantation, but an early signal of graft functioning has still not been established. The aim of the present work is a review of the possibility offered by the clinical biochemistry laboratory GH/IGF investigation in the outcome of liver transplantation.

Many studies on cirrhotic patients have shown that insulin‐like growth factor 1 (IGF‐1) plasma levels are related to the severity of liver dysfunction. This result suggests that IGF‐1 is probably useful for monitoring liver function in the perioperative course of orthotopic liver transplantation (OLT). Growth hormone (GH), IGF‐1 plasma levels, and routine liver function tests were measured in 15 adult cirrhotic patients undergoing OLT. Measurements were made at the beginning of the operation; during OLT; 24 hours after reperfusion; and in the morning on days 7, 30, and 90. Twenty age‐matched healthy volunteers with normal liver function served as controls. The study group had significantly higher GH levels and lower IGF‐1 levels in the preoperative period compared with the controls. All patients achieved a complete functional hepatic recovery 1 month after OLT, although in 6 of them, the graft had an initial poor function (Group‐IPF). GH and IGF‐1 levels achieved near normal range within 1 week after OLT, and they had no significant correlations with other routine biochemistry tests in this period. IGF‐1 levels in Group‐IPF rose more slowly than in the group with a normal recovery of graft function. Surprisingly, 24 hours after reperfusion, IGF‐1 levels were higher in Group‐IPF than in the group with normal graft function. In conclusion, the severe GH/IGF‐1 axis impairment found in patients with end‐stage cirrhosis reverted very rapidly in the first days after successful OLT. Such a quick, postoperative modulation of IGF‐1 plasma level by the graft suggests that this hormone has the potential to become one of the early indicators of post‐OLT liver function recovery.

The development of effective immunosuppressive drugs and the refinement of surgical procedures have led to remarkable improvements in the long-term success of liver transplantation. This procedure is now widely recognised as an effective, preferable therapeutic option for the treatment of end-stage liver disease. The early diagnosis of dysfunction is an indispensable tool for the successful management of the hepatic allograft recipient. Liver function is usually assessed by biochemical and morphological examinations, usually based on coagulation factors (fibrinogen, fibrinogen degradation peptide, factor V, prothrombin time and prolonged thromboplastin time), transaminases, gamma-GT, ALP, bilirubin and lactic acid, and histology. Liver biopsy is usually performed before the implantation of the graft to assess the viability of the liver and following liver transplantation, whenever clinical events warrant it or as part of a routine biopsy schedule.

BACKGROUND Up to 15% of liver transplant candidates have asymptomatic coronary artery diseases, which increase the risk of cardiac complications during and after transplantation. The aim of this study was to prospectively investigate the usefulness of an integrated cardiological approach in cirrhotic patients undergoing liver transplantation. METHODS Twenty-four consecutive patients undergoing evaluation for liver transplantation were studied by assessing risk factors for coronary artery diseases, electrocardiogram with QTc interval determination, chest X-ray, echocardiography, 24-hour Holter monitor, myocardial perfusion scintigraphy (99mTc)MIBI-GSPECT at rest and after dipyridamole infusion. Cardiac (123)I-metaiodobenzylguanidine (MIBG) scan and coronarography were performed in patients with myocardial perfusion defects. Twenty three of 24 patients underwent successful liver transplantation; one patient died on the waiting list. RESULTS Before liver transplantation, 29% of patients were diabetic and 41% were smokers. Eleven of 24 patients had a prolonged QTc interval, and 3/24 had positive myocardioscintigraphy after dipyridamole infusion: in two coronarography was negative, while the (123)I-MIBG washout was altered. No cardiac events were recorded during the short-and long-term follow-up after surgery. CONCLUSIONS Predictive value of positive cardiac (99mTc)MIBI-GSPECT in patients with liver cirrhosis is low, and this may be due to alterations of cardiac microvascular tone as showed by cardiac (123)I-MIBG scan.

BACKGROUND ProANP(1-126), the prohormone synthesized and secreted by atrial myocites, generates an ANP peptide family, the main forms of which are proANP(1-30), proANP(31-67), proANP(1-98) and proANP(99-126). These molecular circulating forms are involved in hemodynamic and electrolyte homeostasis. In cirrhotic patients, volume homeostasis is almost impaired due to abnormal sodium retention, which results in ascites formation and hemodynamic changes, including high cardiac output and low systemic vascular resistance. During liver transplantation, in the anhepatic phase, hemodynamic instability may occur because of decreased venous return due to surgical manipulation of inferior vena cava, considerable blood loss or cross-clamping. Moreover, marked hemodynamic instability is often observed at the reperfusion of the graft. AIMS The aims of present study are to investigate the changes of ANP during the perioperative phases of Orthotopic Liver Transplantation (OLTx) in end-stage cirrhotic patients. PATIENTS AND METHODS From July to September 1999, 11 cirrhotic patients undergoing to OLTx were included in the study: seven males and four females (average age 46+/-10.4 years) affected by post-alcoholic cirrhosis [Hypertension 15 (1990) 9], post-hepatitis cirrhosis [D.G. Gardner, M.C. Lapointe, B. Kovacic-Milivojevic, C.F. Deschepper, Molecular analisys and regulation of the atrial natriuretic factor gene, in: A.D. Struphers (Ed.), Frontiers in Farmacology and Therapeutics: Atrial Natriuretic Factor, Blackwell, Oxford, England, 1991, pp. 1-22], Wilson disease [Life Sci. 28 (1981) 89] and polycystic disease [Life Sci. 28 (1981) 89], autoimmune cirrhosis [Life Sci. 28 (1981) 89]. In each patient, a hemodynamic assessment was achieved using a Swan-Ganz catheter. Periferical venous samples were performed during and immediately after OLTx for the determination of ANP(1-98) and other biohumoral parameters. RESULTS Mean ANP(1-98) (pmol/ml mean+/-SD) basal levels resulted higher than that recorded in the group of healthy subjects. A significant correlation between 24-h post-reperfusion ANP and intra-operative RBC and RIS requirement was found (p<0.05). The basal values resulted significantly higher than that observed at phase II degrees (p<0.04) and lower than that at phase VI degrees (p<0.05); the anesthetic induction values were significantly lower than that observed at phase VI degrees (p<0.03). CONCLUSIONS ANP(1-98) values may represent a useful marker of hemodynamic derangements during and after OLTx. Further clinical correlations will need a larger patient basis.

A 22‐year‐old Caucasian patient underwent living‐donor liver transplantation (LDLT) for hepatic hemangioendothelioma in a healthy liver. The organ donor was his monozygotic twin brother. Surgery was uneventful in both donor and recipient, who received the same postoperative treatment (i.e. no immunosuppression for the recipient). Although both donor and recipient achieved a full liver function recovery, the volume of the recipients graft increased much more than the donors residual liver in the first postoperative month (1.6‐fold vs. 1.2‐fold). This different growth rate correlated with growth hormone (GH)/insulin growth factor (IGF) axis dynamics: the donor had significantly lower insulin‐like growth factor 1 (IGF‐1), insulin‐like growth factor 2 (IGF‐2) and insulin‐like growth factor binding protein 3 (IGFBP‐3) values than the recipient on postoperative days (POD) 3–30, although they had similar GH values. Other potential regenerative factors, e.g. tumor necrosis α, interleukin 6 (IL‐6), insulin and C peptide did not correlate with liver regeneration rate. The particular endocrine picture of the graft may be explained by a modified GH‐hepatocyte interaction due to cold ischemia during preservation resulting in a higher IGF production. Whether this is a potential molecular tool by means of which transplanted partial livers promote their regeneration remains to be seen in a larger number of patients.
