A 36-year-old woman was admitted to our hospital because of general fatigue. The physical and laboratory findings on admission revealed splenomegaly, pancytopenia, hypocoagulopathy, liver hypofunction with a hepaplastin test of 55% and ICG Rmax of 0.6 mg/kg/min. Diagnostic imaging showed a hypoechoic mass 1.5 in diameter a low density area on the CT scan and a faint tumor stain on the AAG in the posterior inferior area of the liver. On a diagnosis of hepatocellular carcinoma with liver cirrhosis and hypersplenism, partial hepatectomy and splenectomy were performed. The resected hepatic specimen revealed a small liver cancer of 1.9 x 1.5 x 1.3 cm with liver cirrhosis. The specimen consisted of a firm rubbery mass. Macroscopically, the tumor appeared oval and was lobulated with a thin capsule. A fibrous scar was observed in the central area. Microscopically, malignant hepatocytes showed various shapes, ranging from polygonal to spindle form, with eosinophilic granular cytoplasm and were surrounded by abundant fibrous stroma. Orcein stain, revealed that these malignant hepatocytes contained many black granules of copper-binding protein. Immunoperoxidase staining for alpha 1-antitrypsin was also positive in the malignant hepatocytes. However, within this lamellar fibrous regions, there were many cords of tumor cells in which nucleoli were absent and abortive biliary differentiation was suggested. Consequently this tumor was diagnosed as an atypical fibrolamellar hepatocellular carcinoma. We think that this case is the 3rd case reported in Japan and the 2nd case in a Japanese person.

The interferons (IFN) act too slowly to arrest acute viral infections, but interferon-alpha (IFN alpha) preparations have proved useful in some chronic infections and will clearly be used increasingly in these in the future. In the preparations derived from human leucocytes or cultured B lymphoblastoid cells, which are in routine clinical use, mixtures of a number of distinct subtypes of human IFN alpha have been identified. There are also 3 slightly different versions of the same single subtype, IFN alpha-2, made by recombinant DNA procedures in bacteria. IFN alpha preparations are injected intramuscularly or subcutaneously. Dose-related side effects are common but usually tolerable, but prolonged treatment may cause increasing fatigue and depression. Some patients form neutralising antibodies which block the effects of the IFN; these appear to be relatively more common after recombinant IFN alpha-2 than after IFN derived from human cells. Given intranasally, IFN alpha can prevent a subsequent experimental rhinovirus infection, or the spread of natural colds within a family. Repeated administration progressively damages the nasal mucosa, so that long term prophylaxis is not possible. IFN alpha has proved useful in patients with papillomavirus warts of the larynx, ano-genital region (condyloma acuminata) and skin (common warts). Treatment regimens remain to be optimised and are likely to include surgery or other treatments. IFN alpha and zidovudine (azidothymidine) synergistically inhibit the growth of HIV in vitro, and combination are on trial in patients with early AIDS. Very large doses of IFN alpha are effective against Kaposi's sarcoma in some AIDS patients. In chronic hepatitis B, continuing virus replication may lead to cirrhosis or primary liver cancer. Earlier clinical trials with IFN alpha gave inconclusive results, but recent large studies have confirmed that 25 to 40% of patients obtain benefit; this probably results from both the antiviral and the immunomodulatory effects of IFN alpha. In patients with chronic hepatitis C, the biochemical markers usually improve rapidly during IFN alpha administration, but relapse if treatment is stopped after only a few months; to increase the chances of sustained cure, the treatment period is now being prolonged.

From 1977 to 1982, 62 patients with various advanced malignant solid tumors were treated by HD-MTX-CFR therapy and totally 129 courses were given. Majority of the patients suffered from malignant lymphoma (10), osteogenic sarcoma (11), lung cancer (16), esophageal cancer (3), breast cancer (3) and malignant melanoma (4). All were confirmed by cytology or pathology except one primary liver cancer. There were clinically measurable lesions in 59 patients for evaluation of the treatment, and 3 osteogenic sarcoma patients without metastasis were given a postoperative adjuvant chemotherapy. 33 out of 62 had received chemotherapy and/or radiotherapy before. Dose of MTX ranged from 2 to 3 gm per course in most patients and dose of CF, from 9 to 12 mg every 6 hours for 3 days. 2 (3.4%) patients achieved complete remission (1 osteogenic sarcoma and 1 malignant lymphoma) and 8 (13.6%), partial remission (1 osteogenic sarcoma, 5 malignant lymphoma, 1 esophageal cancer and 1 breast cancer) with a total response rate of 15.9%. No response was observed in all 16 lung cancers. The main side effects of HD-MTX-CFR therapy were leukopenia, thrombocytopenia, elevation of SGPT, nausea, vomiting, mucositis, skin rash, fever and fatigue. All patients were followed more than 3 years. 4 patients are still alive (9, 9, 4 and 7 years, respectively), including 3 osteogenic sarcoma patients who received postoperative adjuvant chemotherapy and 1 mycosis fungoides.

Eighteen patients with advanced metastatic gastrointestinal cancer (stomach cancer 7, liver cancer 9, pancreas cancer 2) were treated with human recombinant interferon alpha-2 at doses of 3.0 X 10(6)-10.0 X 10(6) IU/body i.m. daily or every second day, 30 X 10(6) IU/body for five consecutive days every four weeks, or 30 X 10(6) IU/body once weekly. No tumor response was demonstrated in any of our cases. Among fifteen evaluable cases, nine had stabilization of evaluable disease at four weeks, but six showed progressive disease. On the other hand, fever, chills, fatigue, anorexia, nausea and vomiting were pronounced. In two cases, CNS toxicities developed. In some instances, leukopenia, thrombocytopenia, decrease of hemoglobin content and elevation of transaminase were observed. According to these findings, single use of recombinant interferon alpha-2 at the dose schedule outlined above does not seem to be of use for the treatment of advanced gastrointestinal cancer.

Twenty patients with primary or metastatic liver cancer were treated on a clinical and pharmacological study with intrahepatic artery infusion of Thiotepa. Toxicity was tolerable and included nausea and fatigue. Uncommon side effects were myelosuppression, abdominal pain and anemia. One patient with gallbladder cancer had a partial response for 11 (+) months. Recommended dose of Thiotepa for future Phase II clinical trials is 1.0 mg/kg. Pharmacokinetics of intrahepatic Thiotepa revealed an extraction ratio similar to that reported for cisplatin. The data suggest increased hepatic clearance for Thiotepa either by binding or metabolism.

Hereditary hemochromatosis is an autosomal recessive disorder, the gene for which occurs in approximately 10% of Americans, most of whom are unaffected heterozygotes. Approximately 5/1000 white Americans are homozygous and at risk of developing severe and potentially lethal hemochromatosis. The disorder affects numerous organ systems, but the most common symptoms are fatigue, palpitations, joint pains, and impotence; the most common signs are those that relate to hypothalamic, cardiac, hepatic or pancreatic dysfunction, including poor cold tolerance, impotence in males, amenorrhea in females, cardiac arrhythmias, dyspnea, edema, hepatosplenomegaly, spider telangiectases, ascites, deformity, swelling or limitation of motion of joints, weight loss, hyperpigmentation. Characteristic abnormalities of laboratory tests include elevated serum iron concentration, high transferrin saturation, elevated serum ferritin concentration, elevated serum transaminases, hyperglycemia and low values for thyroid-stimulating hormone (TSH) and gonadotropins. Death may be the result of cardiac arrhythmia, congestive heart failure, liver failure or liver cancer. Since many of these complications cannot be reversed once they have developed, early diagnosis and treatment are essential. In view of the high prevalence in the American population (prevalence varies with ethnic background), the low cost of diagnosis and treatment, the efficacy of treatment if begun early, and, on the other hand, high costs and low success rate of late diagnosis and treatment, systematic screening for hemochromatosis is warranted for all persons over the age of 20 years. The initial screening should be by measurement of serum iron concentration and transferrin saturation. The practice guideline provides a diagnostic algorithm for cases in which the serum transferrin saturation is 60% or greater. It also provides guidelines for clinical management.

The complications of iron overload in hemochromatosis can be avoided by early diagnosis and appropriate management. Therapeutic phlebotomy is used to remove excess iron and maintain low normal body iron stores, and it should be initiated in men with serum ferritin levels of 300 microg/L or more and in women with serum ferritin levels of 200 microg/L or more, regardless of the presence or absence of symptoms. Typically, therapeutic phlebotomy consists of 1) removal of 1 unit (450 to 500 mL) of blood weekly until the serum ferritin level is 10 to 20 microg/L and 2) maintenance of the serum ferritin level at 50 microg/L or less thereafter by periodic removal of blood. Hyperferritinemia attributable to iron overload is resolved by therapeutic phlebotomy. When applied before iron overload becomes severe, this treatment also prevents complications of iron overload, including hepatic cirrhosis, primary liver cancer, diabetes mellitus, hypogonadotrophic hypogonadism, joint disease, and cardiomyopathy. In patients with established iron overload disease, weakness, fatigue, increased hepatic enzyme concentrations, right upper quadrant pain, and hyperpigmentation are often substantially alleviated by therapeutic phlebotomy. Patients with liver disease, joint disease, diabetes mellitus and other endocrinopathic abnormalities, and cardiac abnormalities often require additional, specific management. Dietary management of hemochromatosis includes avoidance of medicinal iron, mineral supplements, excess vitamin C, and uncooked seafoods. This can reduce the rate of iron reaccumulation; reduce retention of nonferrous metals; and help reduce complications of liver disease, diabetes mellitus, and Vibrio infection. This comprehensive approach to the management of hemochromatosis can decrease the frequency and severity of iron overload, improve quality of life, and increase longevity.

Liver cancer is a leading cancer in Taiwan, especially in males. Transcatheter arterial chemoembolization (TACE) is a major treatment for these patients, but research examining their fatigue experiences is limited. The purposes of this longitudinal, correlational study were to identify (1) changes in fatigue, symptom distress, anxiety and depression in cancer patients across four time points during the first week of TACE treatment, and (2) factors predicting changes in fatigue across the four time points. Eligible male inpatients with liver cancer were recruited from a medical center in Taipei. Subjects (n=40) were assessed 1 day before (T1), and during days 2 (T2), 4 (T3) and 6 (T4) of TACE. Data were analyzed by descriptive statistics, Pearson's correlations, repeated measures analysis of variance (ANOVA) and the generalized estimating equation (GEE). Subjects had mild to moderate levels of fatigue that peaked at T2, and showed a decrease at T3 and T4 but were still slightly higher than at T1. The GEE analysis showed that greater symptom distress, anxiety and depression, higher Adriamycin dosage, longer duration of previous fatigue, and less education significantly predicted fatigue changes. The results indicate that the pattern of fatigue in TACE during the first week is similar to fatigue in patients receiving chemotherapy. The results also further indicate that fatigue is associated to several factors. The causal relationships between fatigue and these related factors should be examined. Interventions targeting these factors should also be tested in future studies.

Non-alcoholic fatty liver disease (NAFLD) covers a wide spectrum of liver pathology--from steatosis alone, through the necroinflammatory disorder of non-alcoholic steatohepatitis (NASH) to cirrhosis and liver cancer. NAFLD/NASH is mostly related with visceral adiposity, obesity, type 2 diabetes melitus (DM t.2) and metabolic syndrome. Pathogenetic concepts of NAFLD include overnutrition and underactivity, insulin resistance (IR) and genetic factor. The prevalence of NAFLD has been estimated to be 17-33% in some countries, NASH may be present in about 1/3 of such cases, while 20-25% of NASH cases could progress to cirrhosis. NAFLD is now recognized as one of the most frequent reason of liver tests elevation without clinical symptoms. Insulin resistance is considering as having a central role in NAFLD pathogenesis. In hepatocytes, IR is related to hyperglycaemia and hyperinsulinaemia, formation of advanced glycation end-products, increased free fatty acids and their metabolites, oxidative stress and altered profiles of adipocytokines. Early stages of fatty liver are clinically silent and include elevation of ALT and GGTP, hyperechogenic liver in USG and/or hepatomegaly. Among clinical symptoms, abdominal discomfort is relatively common as well as chronic fatigue. NAFLD/NASH is not a benign disease, progressive liver biopsy have shown histological progression of fibrosis in 32%, the estimated rate of cirrhosis development is 20% and a liver--related death is 12% over 10 years. No treatment has scientifically proved to ameliorate NAFLD or to avoid its progression. The various therapeutic alternatives are aimed at interfering with the risk factors involved in the pathogenesis of the disorder in order to prevent the progression to end-stage liver disease. The most important therapeutic measure is increasing insulin sensitivity by an attempt to change a lifestyle mostly by dieting and physical activity in order to loose weight. The most used agent is metformin, the others are under controlled trials or their effectiveness is low. NASH is not a common indication for liver transplantation because of the older age distribution of patients and high prevalence of comorbidity, related to metabolic syndrome. Recurence of NASH in the grafted liver is also a relatively frequent complication.

This retrospective study was undertaken to obtain information regarding the survival and toxicities after Yttrium-90 microspheres treatment in patients with primary liver malignancies. Baseline, treatment, and follow-up data were collected and analyzed for 21 patients treated with Yttrium-90 microspheres. Survival analysis was then performed. The results of this study showed that median survival for all the patients was 120 days. Twenty of 21 patients were categorized as high-risk with a median survival of 114 days. It was also found that one high-risk patient has survived 858 days with no recurrence of disease. Acute grade 3-5 toxicities were recorded for nine patients and consisted of elevations in AST and bilirubin, thrombocytopenia, abdominal pain, ascites, nausea, fatigue, and death. This study concluded that Yttrium-90 is a low-toxicity, outpatient alternative for individuals with liver cancer and without many options. The maximal value, however, may lie in the treatment of low-risk patients.
