Analysis of tissue from a recent case of fibrolamellar liver cell carcinoma by several staining and spectrophotometric methods demonstrated elevated copper and copper-binding protein (CBP) in malignant hepatocytes. Production of CBP has not previously been described for this or any other type of hepatocellular carcinoma. Identification of CBP in liver cell carcinoma adds further evidence that this protein is a normal synthetic product of liver cells which may reappear in chronic cholestasis or hepatic malignancy. The mechanism of disturbed copper homeostasis in this case is uncertain.

In retrospective review, 31 patients with carcinoma of the gallbladder and 39 patients with carcinoma of the extrahepatic bile ducts (excluding ampullary tumors) were identified. Case records and operative reports of patients seen between 1955 and 1980 were reviewed for the purpose of evaluating clinical features, preoperative studies, and operative treatment of these two disease processes. Similarities and differences between the two malignancies are highlighted. Demographic features of these patients supported findings of previous studies. Preoperative symptoms were typical of calculus disease often with the stigmata of malignancy superimposed. Laboratory findings provided a rather nonspecific confirmation of cholestasis. Roentgenogram examinations proved to be of little value in differentiating either disease process. A variety of surgical procedures was used by several surgeons to attempt cure or palliation in these tumors. Cholecystectomy was the most frequent procedure performed for patients with gallbladder carcinoma (18 cases). Curative cholecystectomy yielded an average 17.8 month survival. More radical procedures produced higher survival rates although the study size is of questionable statistical significance. Biliary-enteric bypass (choledochojejunostomy) was performed most often for patients with bile duct carcinoma (12 cases). The magnitude of the operation failed to affect the duration of patient survival except in patients with carcinomas of the distal common bile duct. Three Whipple procedures were performed for distal bile duct lesions yielding the one five-year survivor of this study but with an associated 30 per cent operative mortality. Operative strategy and options are discussed. The current literature dealing with these two malignancies is reviewed.

The number, intracellular distribution, and staining characteristics of human hepatocellular peroxisomes that had been made visible by cytochemical staining for catalase were evaluated in biopsies from 75 patients with hepatic, inflammatory, or malignant disease and ten normal individuals. Intensity of staining was found to be proportional to enzymatic activity by microspectrophotometry. Scanning transmission electron microscopy (STEM) image analysis demonstrated an inverse relationship between peroxisomal size and contrast. Peroxisomes were more abundant, and often concentrated in a perinuclear configuration in cholestatic and cirrhotic livers. Decreased peroxisomal staining was common in cholestasis, cirrhosis, hepatitis, and in almost all patients with malignancies, both with and without hepatic metastases.

Records of 19 autopsied patients with metastatic carcinoma were studied to elucidate the contribution to the elevation of antemortem plasma carcinoembryonic antigen (CEA) levels (range, 5.9--136,000 ng/ml) of 1) liver pathology and dysfunction, 2) tumor morphology and CEA content, and 3) tumor spread and location. Liver function tests and plasma CEA recorded within 8 weeks of death, autopsy records of tumor spread, liver weight (as an index of liver tumor mass), and histologic sections were reviewed. Tissue CEA was demonstrated in 15 patients by an immunoperoxidase method. Cholestasis was seen in histologic sections of tissue from 8 of 10 patients, and elevated bilirubin was seen in 7 of 10 patients with hepatic metastases and CEA levels greater than 1,000 ng/ml In contrast, histologically observed cholestasis and elevated bilirubin were seen in only 1 of 8 patients with CEA less than 500 ng/ml. A significant correlation was found between the plasma CEA level and histologically observed cholestasis (P less than 0.01). Serum bilirubin also correlated significantly (P less than 0.01), but alkaline phosphatase did not. Liver weight (tumor mass) showed a positive correlation with cholestasis (P less than 0.01) but not with circulating CEA. Markedly elevated plasma CEA levels (greater than 1,000 ng/ml) seen preterminally may partially reflect impaired excretion of CEA by the hepatobiliary system rather than, or in addition to, preterminal increase in CEA-producing tumor.

The effects of timing of a single intragastric application of dibutyltin dichloride, at a dosage of 30 mg/kg body wt, on N-nitrosobis(2-oxopropyl)amine (BOP)-induced pancreatic carcinomas have been studied in female Syrian golden hamsters. Dibutyltin dichloride, which has been shown to produce selected bile duct injury, was administered either 1 week before or 1 week after a single injection of BOP (20 mg/kg body wt). Control hamsters were injected with BOP alone or were given dibutyltin dichloride alone. The incidence of ductal adenocarcinomas strikingly decreased in hamsters when dibutyltin dichloride was ingested after BOP treatment, but remained unaffected when dibutyltin dichloride was given before carcinogen treatment. Two cases of sarcoma were observed in the group treated with dibutyltin dichloride before BOP injection. The incidence of insulomas, which were considered as spontaneous tumors, was not influenced by dibutyltin dichloride. These results showed that intragastric application of dibutyltin dichloride after BOP treatment significantly reduced the induction of pancreatic cancer. These findings do not support speculations based on epidemiologic studies as to a promoting effect of cholestasis.

Two patients with poor-prognosis leukemia were treated with high-dose cytosine arabinoside (Ara-C), 3 g/m2, for induction. Both patients developed serious jaundice in the second posttreatment week. Clinically, the jaundice was characterized by conjugated hyperbilirubinemia, normal amino transferase levels, significant elevation of alkaline phosphatase, and no evidence of obstruction. Microscopic examination of the liver showed only passive congestion with blood, and no bile lakes or plugs. This was believed to be most consistent with drug-induced intrahepatic cholestasis, possibly as a result of injury to the hepatocyte transport system.

In order to assess the prevalence of venocclusive disease in autopsied recipients of bone marrow transplantation, we reviewed coded liver histology from 204 consecutive autopsied recipients transplanted for leukemia (142), other malignancies (5), or aplastic anemia (57). Twenty-seven patients with leukemia, 2 with carcinoma, and 3 with aplasia had venocclusive disease and survived 2-86 days post-transplant. Early lesions showed subintimal edema and hemorrhage within small central venules and centrilobular congestion with hepatocyte degeneration. Later lesions showed subtotal to complete fibrous obliteration of the central venule lumina and centrilobular sinusoidal fibrosis. Thirteen patients had a subclinical course, and 19 were symptomatic. Venocclusive disease was life-threatening or lethal in 13. Typical symptoms developed 1-3 wk post-transplant and consisted of sudden weight gain, hepatic enlargement, ascites, high bilirubin, and encephalopathy. Statistical analyses showed a significantly higher prevalence of venocclusive disease associated with transplantation for leukemia (P = 0.014), pretransplant conditioning with more rigorous chemoradiotherapy regimens (P < 0.001) and three- to fourfold increase of venocclusive disease in patients whose conditioning included dimethyl busulfan (P < 0.005). Abnormal liver tests before transplant were also more prevalent among patients with venocclusive disease. No factors predicted the clinical outcome of established venocclusive disease. Venocclusive disease showed no association with hepatic graft-versus-host disease even among prolonged cases with severe periportal hepatitis and cholestasis. Other centrilobular lesions (hepatocyte degeneration, sinusoidal fibrosis, and phlebosclerosis) were identified in 23 patients. These non-specific changes may occur with viral hepatitis, graft-versus-host disease or chemoradiotherapy effects.

Pruritus is a cutaneous sensation sharing neural receptors and pathways with pain but is characterized by its own precipitants, potentiators, and range of severity. Among patients with generalized pruritus, the prevalence of systemic disease has been reported as 10% to 50%, with renal, hepatic, hematopoietic, or endocrine causes most commonly identified. Malignant neoplasms, neurologic disorders, certain drugs, or advanced age also may be responsible. Although the pathogenesis of pruritus is unknown, clinically AG event potential mediators have been investigated in several settings. Therapy often fails when the underlying disorder cannot be corrected, but por pruritus associated with chronic renal failure or hepatic cholestasis, specific and usually effective treatments exist.

Sonography has become a widely accepted method for noninvasive imaging of abdominal viscera. This report demonstrates the value of ultrasonography in comparison with other methods in diagnosing gastrointestinal diseases. The sonographic demonstration of an abdominal tumor by ultrasound enables to get informations about the extent, and in connection with sonographically guided fine needle aspiration biopsy about the malignancy of the tumor. In cases of clinically suspected gallstones, biliary obstruction or pancreatic pseudocysts sonography allows the definitive diagnosis and determines the further therapeutical proceeding. In the differential diagnosis of cholestasis ultrasonography should be the initial technique. The differentiation between obstructive and "internal" jaundice can be achieved in most cases, through the cause can not be obtained in all cases. The sonographic findings, however, reduce the differential diagnostic possibilities so that further diagnostics can be abbreviated and coordinated in the right and the patient considerate way. In many clinical situations sonography has to be interpreted in connection with clinical and biochemical findings and the results of other investigations.

A middle-aged woman with evidence of chronic cholestasis of several years and no previous abdominal surgery was initially thought to have primary biliary cirrhosis. Clinical evaluation disclosed a well-developed secondary biliary cirrhosis apparently caused by extrahepatic obstruction due to a 1 X 2 cm neoplasm of the periampullary duodenum. Electron microscopy and immunofluorescent studies showed the neoplasm to be a G-cell adenoma. Wide local excision has resolved the biliary obstruction. Bening or slow-growing duodenal tumors, if they involve the ampulla of Vater, may produce prolonged partial extrahepatic obstruction and secondary biliary cirrhosis.
