In a consecutive 440 autopsy cases of hepatocellular carcinoma (HCC), 13 patients (2.95%) were found to have a second primary malignant tumor. All of the patients were male. The age ranged from 40 to 69 years old. (mean: 56.5) Peak incidence occurred in the seventh decade. The associated neoplasms included 4 cases of colorectal adenocarcinoma, 2 cases of thyroid cancer, 2 cases of retroperitoneal sarcomas, 1 case of pancreatic adenocarcinoma, 1 case of esophageal squamous cell carcinoma, 1 case of common bile duct adenocarcinoma, 1 case of renal cell carcinoma, and 1 case of prostatic adenocarcinoma. The organ most commonly involved was large bowel (4 cases). Epithelial origin neoplasms comprised the vast majority (84.6%). Of the 13 cases, 2 associated malignancies existed metachronously, 4 and 5 years before HCC. The others were found at the same time as HCC. The clinical and pathological observations included age, sex, serum alpha-fetoprotein (AFP), serum hepatitis B surface antigen (HBsAg), cirrhosis, gross and histologic appearance. The above presentations were similar in cases with and without second malignancy. We failed to find any factor that was possibly related to the etiology of the second neoplasm. Much more such cases are needed for further evaluation.

From April 1978 to 1st October 1990, 19 patients underwent liver transplantation for primary or secondary cancer of the liver. Eleven patients were transplanted for hepatocellular carcinoma secondary to cirrhosis, generally alcoholic (9 cases), hepatitis B (1 case) or secondary to haemochromatosis (1 cas). Three patients developed hepatocellular carcinoma in a normal liver, including one fibrolamellar cancer and three a proximal bile duct cancer. Lastly, two patients received a graft for secondary cancer from a colonic adenocarcinoma and a carcinoid tumour of the right colon. The operative mortality was nil for the transplantations for cancer in a normal liver, but there were 4 deaths out of the 11 cases of cancer secondary to cirrhosis. The actuarial survival of the overall series was 55% at 1 year and 31% at 2 years. The poorest survival was observed for cancers in a normal liver, with the exception of the fibrolamellar cancer in which recurrence was delayed. The longest survival was observed for cancers secondary to cirrhosis. At three years, the results of liver transplantation were equal to those of hepatic resections with a survival of 37%, despite the fact that the transplantation was generally performed for very large tumours.

Four cases of type 2 hepatitis B virus (HBV-2) infection were demonstrated in the Gizan area of Saudi Arabia during the hepatitis B marker ELISA screening of the 152 native pregnant females, 42 cases of primary hepatocellular carcinoma, 19 cases with an epithelial but non-hepatic malignancy, 16 with a non-epithelial and non-hepatic malignancy and eight with chronic hepatitis. HBV-2 infection diagnosis was based on HBsAg positivity without anti-HBc, anti-HBs and HBeAg in one pregnant female and one patient each with a primary hepatocellular carcinoma, lymphocytic lymphoma and metastatic adenocarcinoma. During neutralisation of HBsAg ELISA reactivity, the respective reduction in absorbance values in sera from the pregnant female and the patient with primary hepatocellular carcinoma were 21% and 76% respectively. HBV-2 specific gene probes would be needed to define its role in pathogenesis of malignant neoplasms and chronic hepatitis. Incorporation of pre-S2 sequences in future hepatitis B vaccines is likely to protect against both, HBV-2 and conventional hepatitis B (HBV-1) exposures.

Immunofluorescent staining of HeLa cells with rabbit antiserum raised against isolated HeLa cell nucleoli showed bright nucleolar fluorescence. Immunoprecipitation of nuclear extracts obtained from HeLa cells labelled with 35S-methionine or 32P-orthophosphate followed by gel electrophoresis of the precipitate revealed a major band of 90 kd. This antigen, called pp90, was judged to be responsible for the nucleolar fluorescence. Serine residues were predominantly phosphorylated in pp90. Similar nucleolar fluorescence was observed commonly in human cells derived from malignant tumors including acute lymphatic leukemia, adult T-cell leukemia, hepatitis B virus-associated hepatoma, adenocarcinoma, and in 5 lymphoid cells derived from Burkitt lymphoma but not in normal human lymphocytes or liver cells. In immunoprecipitation, 32P-labelled pp90 was commonly detected as the major component in all of those cells which showed nucleolar fluorescence. Resting human embryo lung (HEL) cells were negative for both nucleolar fluorescence and pp90 in immunoprecipitation, but turned positive when stimulated to grow, suggesting the involvement of pp90 in cell growth. Antigen pp90 was also induced in human lymphocytes and HEL cells by infection with Epstein-Barr virus in human cytomegalovirus, respectively, which are known to induce cell DNA synthesis in early stages of infection. A cross-reacting nucleolar antigen was detected in 2 monkey cells but not in 3 rodent cells tested.

To determine the prevalence and clinicopathologic features of cholangiocarcinoma (CC) associated with nonbiliary cirrhosis, we performed a clinicopathologic study. Among the 5,563 autopsies in our laboratories during the past 14 years, 85 (1.5%) were CCs. Four (4.7%) were associated with cirrhosis, due to hepatitis B virus in one case and cryptogenic (probably non-A non-B hepatitis virus) in the remaining three. Clinically, patients with CC and cirrhosis were characterized by male preponderance, lower age, past history of liver injury, and elevated values of zinc sulfate and thymol turbidity tests. Pathologically, all CCs with cirrhosis were basically adenocarcinoma; other histologic features included adenocarcinoma resembling bile ductules without mucin (one case), adenocarcinoma with broad areas of signet ring cell carcinoma (one case), adenocarcinoma with extensive sarcomatoid transformation (one case), and adenocarcinoma associated with hepatoliths (one case). Immunohistochemically, immunophenotypes of carcinoma cells of CC with cirrhosis were not different from those of CC without cirrhosis. Carcinoembryonic antigens, CA19-9, DU-PAN-2, and biliary-type cytokeratins were positive and alpha-fetoprotein was negative, suggesting that our CCs are not hepatocellular neoplasms but true CCs. It must be stressed that there are actual CCs arising in nonbiliary cirrhotic livers.

We present a case of primary biliary cirrhosis associated with simultaneous triple cancers: a hepatocellular carcinoma and adenocarcinomas of the common bile duct and gall-bladder. A 70 year old Japanese woman, who had been diagnosed with primary biliary cirrhosis (stage 2 by Scheuer) 15 years before, was admitted to Koseiren Kamo Hospital in a comatose state. Laboratory data were as follows: the ammonia level was high (164.0 micrograms/dL), the antimitochondrial antibody showed a 320-fold increase, a high level of alpha-fetoprotein was indicated (2677 ng/mL), hepatitis B surface antigen was negative and hepatitis C antibody by enzyme immunoassay was negative, although a test for the RNA of hepatitis C virus by polymerase chain reaction was positive (10(3.5) copies/50 microL). The patient's condition gradually worsened and the patient died of liver failure. Autopsy showed triple cancers in the liver (hepatocellular carcinoma; trabecular type, moderately differentiated), the common bile duct (well-differentiated papillary adenocarcinoma) and the gall-bladder (well-differentiated papillary adenocarcinoma) with primary biliary cirrhosis (stage 4). Primary biliary cirrhosis has been believed to be a low risk for the development of hepatocellular carcinoma, despite the high risk of extrahepatic malignancy. The simultaneous occurrence of triple cancers with primary biliary cirrhosis, to the best of our knowledge, has never been reported. The present case may provide additional evidence for a predisposition to malignancy in primary biliary cirrhosis.

We herein present a case of resected synchronous solitary liver metastasis from alpha-fetoprotein (AFP)-producing early gastric cancer. A 61-year-old woman, who was diagnosed at a routine medical checkup as having early gastric cancer with a liver tumor, came to our hospital for surgery. Her serum AFP level was high at 910 ng/ml. An examination was performed to determine whether the liver tumor was primary hepatocellular carcinoma or metastasis from early gastric cancer. She had no evidence of either a hepatitis B or C virus infection, and her liver function was normal. A biopsy specimen from the gastric cancer predominantly revealed moderately differentiated adenocarcinoma, but a focally trabecular pattern compatible with AFP-producing gastric cancer was also observed. Preoperatively, it was concluded that the liver tumor was metastasis from an AFP-producing early gastric cancer. We thus performed distal gastrectomy and a posterior segmentectomy of the liver. Her serum AFP level decreased to the normal range within 2 weeks after the operation. An immunohistological examination revealed that AFP-positive cells were present in both the gastric cancer and liver tumor. One year after the operation, there was no sign of recurrence.

Tumor metastasis to a cirrhotic liver is rare. It has been suggested that colorectal cancer does not metastasize to the cirrhotic liver. We reported a 65 year-old man, a known carrier of hepatitis B surface antigen, diagnosed to have hepatocellular carcinoma with routine screening. A partial hepatectomy with resection of segments VI and VII was performed. The hepatectomy specimen revealed a 4.5 cm diameter HCC in a cirrhotic liver. Incidentally, 0.8 cm diameter ulcer at the descending colon. Histological examination of the left hemicolectomy specimen showed a moderately differentiated adenocarcinoma.

Recently, hepatitis virus-associated chronic hepatitis or cirrhosis has been suggested to be involved in the pathogenesis of cholangiocarcinoma (CC). A 52-year-old man was diagnosed as CC with a background of hepatitis B virus (HBV)-dependent cirrhosis. A minute hepatic tumor was found during the follow-up, and was diagnosed as CC on percutaneous biopsy. The patient died of hepatic failure and an autopsy revealed the tumor to be a well to moderately differentiated adenocarcinoma. An immunohistological analysis of HBV X gene-encoded protein (HBX) was neither detected in the cancerous nor in the noncancerous tissue. No oncogenic role of the virus was verified in this case.

A 41-year-old man with Cronkhite-Canada syndrome presented with multiple juvenile polyps with hyperplastic and adenomatous changes throughout his stomach and entire colorectum. Dysgeusia was recognized and the degree of hypoproteinemia was remarkable. A barium enema study and colonofiberscopy also revealed an advanced cancer in the rectum. Chronic hepatitis B and membranous glomerulonephritis were also present. It was difficult to design a conservative protocol using steroids for the treatment of protein-loosing enteropathy because the patient was a hepatitis B virus carrier. As a result, a subtotal colectomy while preserving the cecum with cecorectal anastomosis was performed. Pathologically, the ulcerated rectal tumor was a moderately differentiated adenocarcinoma with invasion into the muscularis propria. Most polyps showed cystically dilated glands without dysplasia or edematous stroma with inflammatory cell infiltration. A few polyps were juvenile-type polyps with adenoma components. Although no remarkable improvement was observed in the hypoproteinemia postoperatively, an alpha1-antitrypsin clearance test showed a significant decrease in protein loss from the gastrointestinal tract, which was only about one third of the loss seen preoperatively. These findings lead us to conclude that when improvement using conservative treatment can be neither obtained nor is expected, then the use of surgery should be considered when treating patients with Cronkhite-Canada syndrome.
