Consecutive autopsies (5241) performed in the Trieste area and consecutive autopsies (6511) performed in the Tokyo-Chiba area were analyzed to study the frequency of liver metastases in cirrhotics. The Italian material included 500 cases and the Japanese material included 529 cases of liver cirrhosis. Both of these groups were matched for sex and age with a control group. The results were similar in both areas and confirmed the widely held but disputed opinion that metastases in cirrhotic liver are rare. These results seem to be clinically important since they agree with the fact that most neoplasms in cirrhotic liver are primary. From a biologic and epidemiologic point of view, these results call for reconsideration of the complex relationship existing between cancer and liver cirrhosis, in relation to major causative factors such as alcohol and hepatitis B virus (HBV) infection.

Over a 9-year period, major resection was successfully performed on 51 occasions with total vascular exclusion using supra- and infrahepatic caval and portal vein clamping. The main indications for hepatic resection were centrally located tumor in liver metastases (62%) and hepatocellular carcinoma with no evidence of co-existing cirrhosis (25%). Major resections included extended and regular right hepatectomy, extended left hepatectomy, and segmentectomy. The mean duration of vascular exclusion was 46.5 +/- 5.0 minutes (range 20 to 70 minutes) and mean blood transfusion requirement was 1.4 +/- 0.4 units during vascular exclusion. There were significant correlations between postoperative fall in factor II levels and the number of segments removed (r = 0.37, p = 0.015) and between serum alanine aminotransferase levels at day 2 and the duration of vascular exclusion (r = 0.35, p = 0.02). One patient died 45 days after the procedure of multi-organ failure and sepsis. Nonfatal complications occurred in 7 patients (14%) and included respiratory infection (7 patients), biliary fistula (3 patients), and collection at the site of hepatic resection (3 patients). Total vascular exclusion is a safe and useful technique in resection of major hepatic lesions that involve hepatic veins.

Between 1982 and 1986, liver segmentectomies were performed in 19 patients with liver tumors, including ten hepatocellular carcinomas, six liver metastases, one cholangiocarcinoma, and two benign tumors. During surgery, patients received a mean (+/- 1 SD) of 1050 +/- 150 mL of packed red blood cells and 860 +/- 80 mL of fresh-frozen plasma. There were no operative deaths. The only complication was a prolonged leakage of ascites through the abdominal drain in one patient with cirrhosis. Seven patients with hepatocellular carcinoma were still alive at this writing, with a follow-up ranging from two months to four years. The four patients with metastases from colorectal carcinomas were alive after follow-up times ranging from six to 24 months. These results suggest that liver segmentectomy is a safe procedure and should be considered as the operation of choice for resection of limited liver tumors.

The authors reviewed the liver histopathology and the clinical features of eight patients with liver metastases from colorectal cancer who were treated by hepatic arterial infusion chemotherapy (HAIC) via an implantable pump (Infusaid). Before HAIC, these patients had no evidence of hepatitis, and results of liver biopsies performed on three patients showed only minor morphologic alterations. All the liver tumors responded to HAIC, but all patients developed hepatitis. Clinical findings included nausea, vomiting, abdominal pain and jaundice. Serum transaminases, alkaline phosphatase and bilirubin levels were increased. Clinical observations suggested that 5-fluoro-2'-deoxyuridine (FUDR), the predominant drug given, was the hepatotoxic agent. Toxic effects were hepatocyte necrosis, steatosis, cholestasis, central vein sclerosis, and alterations in the portal triad. In addition, central vein lesions like those in veno-occlusive disease, and micronodular cirrhosis resembling that induced by alcohol, were encountered. Although individual susceptibility to FUDR appeared to vary, portal triad fibrosis was present in all eight cases and, together with central vein sclerosis and cirrhosis, appeared to be related to the dose and duration of HAIC.

Technetium-99m galactosyl-neoglycoalbumin ( [Tc]NGA) is a radiolabeled ligand to hepatic binding protein, a receptor which resides at the plasma membrane of hepatocytes. This receptor-binding radiopharmaceutical and its kinetic model provide a noninvasive method for the assessment of liver function. Eighteen patients were studied: seven with hepatoma, eight with liver metastases, four with cirrhosis (two had concurrent hepatoma and one chronic active hepatitis), and one patient with acute fulminant non-A, non-B hepatitis. Technetium-99m NGA liver imaging provided anatomic information of diagnostic quality comparable to that obtained with other routine imaging modalities, including computed tomography, angiography, ultrasound, and [Tc]sulfur colloid scintigraphy. Kinetic modeling of dynamic [Tc]NGA data produced estimates of standardized hepatic blood flow, Q (hepatic blood flow divided by total blood volume), and hepatic binding protein concentration, [HBP]. Clinical correlation was by classical Child-Turcotte criteria (CTC). Significant rank correlation was obtained between [HBP] estimates and CTC scores (rs = -0.72, p = 0.001). This correlation supports the hypothesis that [HBP] is a measure of functional hepatocyte mass. The combination of decreased Q and markedly reduced [HBP] may have prognostic significance; all three patients with this combination died of hepatic failure within 6 wk of imaging.

The presence of HBsAg was detected in the serum of 1 out of 13 patients with chronic hepatitis, in 2 out of the 7 patients with liver metastases, but in none of the 10 patients with hepatocellular carcinoma (HCC) investigated. HBsAg could be visualized by orcein staining in the liver cells of 66.6% of the HCC patients, in 50% of the patients with liver metastases and in 40% of the patients with liver cirrhosis. The prevalence of anti-HBs was low both in HCC patients and in the control groups. The possible significance of these findings is discussed.

In a series of 2,538 cases of cirrhosis seen at laparoscopy there were 140 primary liver carcinomas and 19 cases of metastases to a cirrhotic liver out of a total of 167 extrahepatic neoplasms associated with cirrhosis. In an autopsy series of 1,073 cases of cirrhosis there were 190 primary liver carcinomas and 22 cases of metastases to a cirrhotic liver out of a total of 98 extrahepatic neoplasms. In another autopsy series of 498 cases of cirrhosis there were 71 primary liver carcinomas and 18 cases of metastases to a cirrhotic liver out of a total of 58 extrahepatic neoplasms. The laparoscopy series showed a predominance (31.8%) of esophageal tumors associated with cirrhosis, but these tumors rarely gave rise to liver metastases (3.7%); in the autopsy series there was a predominance (35.3%) of tumors of the portal territory, giving rise to metastases in cirrhotic livers in 35.2% of cases.

Two investigators were asked to evaluate independently the echogenicity, coarsening and inhomogeneity of the hepatic echo pattern in a semi-quantitative manner; they had no knowledge of the diagnosis and used the same apparatus. The three subjective criteria were largely independent from the observer. Approximately three-quarters of all patients with slightly increased echogenicity showed a subjective appearance of coarsening; the impression of inhomogeneity increased significantly with increasing echogenicity. This is of importance in the sonographic evaluation of cirrhosis of the liver and in the diagnosis of diffuse liver metastases in a fatty liver. Grey scale analysis within a region of interest showed satisfactory correlation between the measured mean grey scale and echogenicity. Standard deviation within the grey scale was redundant, and there was no correlation between the other subjective characteristics and quantitatively measurable values.

To evaluate the diagnostic accuracy of fibronectin levels in ascites to differentiate malignant from non-malignant ascites, the authors studied 30 patients with sterile uncomplicated ascites in chronic liver disease, 18 patients with malignant ascites and four patients with spontaneous bacterial peritonitis. Fibronectin concentration was significantly higher in malignant ascites than in sterile ascites (P less than 0.001). High values (greater than 85 mg/l) were found in four of six cases of hepatocellular carcinoma in liver cirrhosis with negative cytologic examination, and in six of seven peritoneal carcinomatoses. Low values (less than 85 mg/l) were found in four patients with liver metastases and in one patient with intrahepatic biliary duct carcinoma in cirrhosis. In four patients with infected ascites, the fibronectin level was low. Among all other parameters (total protein concentration, lactate dehydrogenase, gamma-glutamyl-transpeptidase, pH, amylase, triglycerides, leukocyte count, and cytologic examination), fibronectin yielded the best degree of discrimination (diagnostic accuracy, 79%).

Tumor surgery in this field is no longer such a high risk as previously. Prolonged survival can be achieved by resection of hepatocellular carcinomas in non-cirrhotic livers (3-year survival 58%, n = 54 patients) and for colorectal liver metastases (3-year survival 44%, n = 124 patients). But surgery is rarely successful for the most frequent type of liver malignancy, the hepatocellular carcinoma in cirrhosis. Central bile duct carcinomas are now resected more frequently than in the past. Liver grafting seems indicated in special cases of liver and bile duct tumors. The future developments of operating on the in situ-perfused liver was discussed and the first operation on an ex situ-liver was demonstrated.
