The authors have presented their observations in 108 pathologically processed cases of primary hepatic carcinoma (PHC). The material includes the period from 1962 to 1990. The most frequent form of PHC was hepatocellular (67.5%), the cholangiocellular (29.5%) and rarest, the mixed hepato-cholangiocellular form (2.9%). X-ray diagnostics were applied (celiacography, arteriography), laparoscopy, ultrasonography, aimed and blind aspirational biopsy, and laboratory examinations (alkaline phosphatase, transaminases, bilirubin, gamma-CT and so on). Somewhat more attention is given to the problem of HBV infection as the cause of primary hepatic carcinoma development. Pre-existing liver tissue diseases are also pleaded for (chronic aggressive hepatitis, hepatic cirrhosis, ect.). Beside the many diagnostic procedures, the diagnosis of primary hepatic carcinoma is usually established too late, and the therapy still remains unsatisfactory.

The probability that routine hematological laboratory tests of liver and pancreatic function can discriminate between malignant and benign pancreatic tumours, incidentally detected during operation, was investigated. The records of 53 patients with a verified diagnosis of pancreatic carcinoma and 19 patients with chronic pancreatitis were reviewed with regard to preoperative total bilirubin, direct reacting bilirubin, alkaline phosphatase, glutamyltranspeptidase, aminotransferases, lactic dehydrogenase and amylase. Multivariate and discriminant analysis were performed to calculate the predictive value for cancer, using SYSTAT statistical package in a Macintosh II computer. Total and direct reacting bilirubin and glutamyltranspeptidase were significantly higher in patients with pancreatic carcinoma. However, only considerably increased levels of direct reating bilirubin were predictive of pancreatic carcinoma.

4'-Epidoxorubicin (Epi-A) administered immediately prior to liver resection has been suggested as treatment for patients with primary liver carcinoma. Long-term toxicity was studied in rats given a single dose of Epi-A intravenously immediately prior to a standard partial hepatectomy (PH). After 52 weeks only 9% of the rats given 5 mg/kg + PH were alive, 79% of the rats given 2 mg/kg + PH and 92% of the PH control survived. The weight gain of the rats given 5 mg/kg + PH was only 17% of that of PH controls. Signs of congestive heart failure were observed in some rats while in others moderate kidney lesions. No histopathological lesions were detected by light microscopy in heart, liver, spleen and bone marrow. For the rats given 2 mg/kg + PH body weight gain, microscopic observations and blood chemistry data (total protein, albumin, alkaline phosphatase, alanine aminotransferase, total bilirubin, creatinine and urea) were comparable to the PH controls. No significant differences in survival were registered between partially hepatectomized and sham-operated rats. The results indicate that Epi-A may be given preoperatively to liver resection without inducing long-term effects on vital organs.

We investigated the effects of once-daily oral administration of 10 mg/kg ursodeoxycholic acid (generic name, ursodiol) on elevated serum enzyme activities, bilirubin, cholesterol, bile acids and symptoms in patients with primary sclerosing cholangitis. A 30-mo, open-label, pilot trial was designed to cover four periods: (a) 3 mo of pretreatment observation (period 1), (b) 6 mo on ursodiol (period 2), (c) 3 mo withdrawal of treatment (period 3) and (d) 18 mo of extended retreatment (period 4). Diagnosis was confirmed by cholangiography and liver biopsy specimens. We enrolled 12 patients with persistently elevated pretreatment alkaline phosphatase and gamma-glutamyltransferase levels (at least twice the upper limit of normal), and observed them for a median of 37 mo. Significant reductions in serum total cholesterol levels and in serum enzyme activities indicating cholestasis and hepatocellular injury occurred during ursodiol treatment in both treatment periods 2 and 4 and relapsed with treatment interruption in period 3. Elevated serum bilirubin and symptoms of disabling fatigue, pruritus and diarrhea were improved by ursodiol. Improvements have continued after 2 yr of treatment in 10 patients (1 patient had a transplantation after he relapsed on withdrawal of ursodiol therapy; another died of postoperative complications of colon resection for carcinoma). No other cases of clinical deterioration were observed in the retreatment period. The longer term reductions of alkaline phosphatase, transaminases, bilirubin and cholesterol after 2 yr of treatment were even greater than the initial reductions after 6 mo of treatment. These results justify initiation of larger, controlled clinical trials, with serial morphological evaluations of the liver and biliary tree.

Computed tomography, ultrasound, nuclear scintigraphy, and laboratory tests (lactic dehydrogenase, alkaline phosphatase, and 5-nucleotidase) were compared in 135 patients with gastro-intestinal carcinoma to define the most useful test to detect hepatic metastases. Thirty-six patients (26.7 per cent) had hepatic metastases at laparotomy. Sensitivities were low: 46.2 per cent for nuclear scintigraphy, 57.6 per cent for ultrasound, 67.7 per cent for computed tomography and 62.9 per cent for lactic dehydrogenase. Accuracies ranged from 62.9 (lactic dehydrogenase) to 77.6 per cent (nuclear scintigraphy). No significant differences were found. Accurate and efficient detection of hepatic metastases is hampered by relatively low sensitivity, specificity and accuracy of the conventional imaging tests and laboratory tests.

Five of 23 patients with recurrent nasopharyngeal carcinoma (NPC) were diagnosed to have bone marrow metastasis. They all had advanced local-regional disease, and were treated with neoadjuvant chemotherapy and definitive radiotherapy after the initial diagnosis. Bone marrow metastasis developed 4-24 months later. The clinical features were anemia (5 of 5), leukopenia (3 of 5), thrombocytopenia (4 of 5), sepsis (3 of 5), tenderness of the sternum (3 of 5), and fever (4 of 5). Patients frequently had elevation of serum lactic dehydrogenase (LDH), alkaline phosphatase (ALK-P), and IgG and IgA antibody titers to Epstein-Barr viral capsid antigen when bone marrow involvement was diagnosed. However, clinical manifestations and laboratory tests were not specific. It is important that three patients had normal bone scans. All five patients had a rapid downhill course; four patients died within 23 days, and the fifth 3 months after the diagnosis of bone marrow metastasis. We concluded that bone marrow was a common metastatic site in NPC patients. Bone marrow metastasis adversely affected patients' survival and required a high index of suspicion for diagnosis. We suggested that bone marrow biopsy should be considered as a routine staging procedure in NPC patients and indicated especially when patients presented with abnormal blood counts, sepsis, bone pain, or tenderness of the sternum. It may be positive in the face of a normal bone scan.

The aim of this study was to produce large liver tumors reliably, and to diagnose the tumors during development. Therefore, New Zealand white rabbits were treated with N-nitrosodiethylamine orally three times per week by gavage and were examined by clinical-chemical assay at regular intervals during the average treatment period of 14 months. The total cumulative dose was 1200 mg N-nitrosodiethylamine over 14 months. After a short treatment period the initial dose of 3 mg/kg had to be reduced to 1.5 mg/kg. In all 11 treated animals (100%) liver tumors were seen at the end of the study. Four control animals did not show any neoplastic changes. Clinical parameters investigated were for an assessment of liver function, total protein, urea, creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin and neuraminic acid as well as some serum electrolytes. The in vivo diagnosis of liver tumors based on changes in these parameters proved to be relatively unreliable. The liver enzyme tests and urea concentration only yielded significant changes when the liver tumors were very large. Changes in neuraminic acid levels were the most reliable indicator for the presence of a liver tumor in this animal model. In the 11 treated animals, serum values of this marker increased towards the end of the study by an average of 300 mg/dl. The induced tumors were mainly hepatocellular carcinomas. Only in 1 animal was a hepatocellular adenoma found. Further primary tumors diagnosed were six adenomas in the kidneys and two uterus adenomas, as well as nasal cavity tumors (two papillomas, one carcinoma, one adenoma and one adenocarcinoma). In 70% of the treated rabbits the hepatocellular carcinomas had metastasized to the lungs.

In order to elucidate the cell characteristics of head and neck squamous cell carcinomas, the cell kinetics and lectin binding patterns were compared with the histological classification and staging of the tumors, using surgically resected materials (maxillary sinus 10, oral cavity 21, pharynx 8, larynx 11). Eight biotinylated lectins (WGA, 1-PHA, ConA, UEA1, RCA1, SBA, DBA, PNA) were applied to the paraffin-embedded sections, and were visualized histochemically by the streptavidin-alkaline phosphatase method. The DNA contents of the isolated carcinoma cells obtained from the adjacent thick sections were evaluated using an epi-illumination cytofluorometer after propidium iodide staining. On lectin histochemistry, the binding pattern of WGA lectin was similar between carcinoma tissues and normal tissues, but the binding was more intense in well differentiated than less differentiated carcinomas. Lymph node metastasis was found to be related to the presence of cells with poor WGA-binding. In the binding patterns of the other lectins, RCA1, SBA and ConA were related to the differentiation of carcinomas, but they were not related to the TNM-classification. DNA cytofluorometry exhibited marked polyploidization, which progressed with the advancement of the clinical and pathological staging of carcinomas. However, the DNA ploidy pattern was not associated with the cell characteristics such as the degree of histological differentiation and the lectin-binding pattern, except that the appearance of aneuploidy had some relationship with the binding-patterns of UEA1 and 1-PHA.

A series of 15 patients with perihilar biliary carcinoma treated by intrahepatic biliary-jejunal anastomosis at our department was studied to determine its adequacy for bilirubin clearance, the decrease of alkaline phosphatase (AKP) value, the duration of relief from jaundice, the length of hospital stay, life quality and survival time of the patients. Intrahepatic bypasses were shown to allow bilirubin to return to normal or nearly normal value. Free from jaundice persisted until death for most cases. The postoperative decrease of AKP value was in an irregular pattern. Postoperative reflux cholangitis was not found in any patients. There was only one death during hospital stay. Most patients survived more than 6 months. A satisfactory palliation was achieved by the intrahepatic biliary-jejunal anastomosis. A new method for palliative diversion of the bile by means of creating an internal fistula between a bile duct in segment v and gallbladder and an anastomosis of the gallbladder to the jejunum was introduced.

Fluosol, a perfluorcarbon emulsion, has the ability to carry oxygen in solution. In conjunction with oxygen breathing and radiation, Fluosol has been shown in animal models to enhance local tumor control. In September 1985, a Phase I/II Study was instituted to evaluate the effect of this adjuvant therapy with radiation in non small cell carcinoma of the luing. Fifty patients were enrolled in the study which was closed for accrual in November 1987. Five patients were withdrawn prior to the institution of radiation: one patient diagnosed with bone metastasis and four patients withdrawn due to mild to moderate reactions to Fluosol. Of the 49 patients administered Fluosol, 34 mild to moderate adverse reactions were noted in 22 patients to either the test dose/infusion (16 reactions including withdrawn patients) or post infusion (18). Flushing, dyspnea and hypertension (test dose/infusion) and chills and/or fever (postinfusion) were the typical symptoms. Transient elevation of blood chemistries (SGOT, SGPT, alkaline phosphatase, BUN) were noted in some patients. Six patients had transient depression of WBC counts (toxicity scores of 1 or 2) and two patients had transient depression of platelets (toxicity score of 1). None of these altered treatment. Forty-five patients received Fluosol of which 34 completed the planned therapy. Six patients were diangosed with metastatic disease during therapy and three patients died of their disease during treatment. One patient was withdrawn due to ineligibility and one patient withdrawn due to moderate reactions to Fluosol during the 3rd and 4th infusions. The total dose of Fluosol was escalated from 42 mL/Kg to 49 mL/Kg in 5, 6, or 7 weekly infusions. Patients breathed 100% oxygen for a minimum of one-half hr prior to and during radiation treatment. Radiation therapy was administered at a daily fraction of 165 to 200 cGy per fraction to a total dose of 5940 to 6800 cGy. Seventeen of 34 patients (50%) achieved a complete response to treatment and 11 patients (32%) had a partial response. Thirteen patients remain alive (range of 12 to 20 months) including 10 of 17 complete responders, 2 of 11 partial responders, and 1 treated with chemotherapy postradiation. The median absolute survival time of the patients completing therapy was 15.5 months and the 12 and 18 month absolute survival rates were 81% and 74%, respectively. The 45 patients starting protocol therapy had a median absolute survival of 9.2 months with a 12-month and 18-month survival of 45% and 35%, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)
