RESUMEN
A 63-year-old male complained of right upper abdominal pain and jaundice. Laboratory data on admission showed hyperbilirubinemia, elevation of biliary enzymes and an extraordinarily high value of serum CA19-9 (60,000 U/ml). Diagnostic imaging modalities including abdominal ultrasonogram, abdominal CT and PTC suggested a stone impaction of the common bile duct. Jaundice subsided after PTC-drainage in association with decreasing serum CA19-9 value, which returned to the normal level six weeks later. Spontaneous delivery of the stone via the fistula was confirmed by cholangiography through the drainage tube. Though there are few reports of such a high serum CA19-9 level, the possibility of benign biliary tract disease should be considered in patients showing an extraordinarily high serum CA19-9 value.

Five hundred fifty patients hospitalized to our hospital during 1990 to 1999 were studied. Subjects consisted of 413 males and 102 females and mean age was 62.1 years. Association with HBV infection, HCV infection and both infection was 11.1%, 78.4% and 2.5% respectively. According to the criteria based in Liver Cancer Study of Japan, 5 year survival rate in clinical stage I, II, III was 42.3%, 38.8% and 17.5%. Tumor morphology was nodular type in 78.9%, massive type in 9.1% and diffuse type in 10.5% of cases. Portal tumor thrombus and distal metastasis were observed in 19.9% and 6.3% of all cases. The 1-, 3- and 5-year survival rate in patients received any therapy was 80.8%, 44.6% and 28.7%, respectively. Analysis by the proportional hazard model showed that HBV infection, advanced clinical stage, multiple tumors, a tumor diameter in excess of 5 cm and AFP positivity were shown as significant factors on poor prognosis.

To elucidate a role of TTV infection in patients with acute liver injury, TTV-DNA in the sera from 97 patients with acute liver injury of various etiology were determined according to Okamoto's method. Out of 77 patients with acute liver injury of determined etiology, 31 patients(40.3%) showed TTV-DNA positive, and out of 15 patients with acute liver injury of undetermined etiology, 8 patients(53.3%) showed TTV-DNA positive. These results suggested no evident role of TTV in patients with acute liver injury was shown. Further study including genotype and quantitative determination of TTV-DNA and antibody assay is needed.

AIMS/BACKGROUND: Although serum PIVKA-II has been widely used as a tumor marker for hepatocellular carcinoma (HCC), little information is available concerning tissue PIVKA-II, and detection of tissue PIVKA-II in paraffin-embedded tissue specimens of HCC is also considered difficult. METHODS: Paraffin-embedded HCC tissues obtained at autopsy from 22 patients were subjected to immunohistochemical staining using the antibody MU-3 (Eisai Co., Ltd.) after microwave antigen retrieval. RESULTS: PIVKA-II was mainly detected in the cytoplasm of HCC cells. The intensity of tissue PIVKA-II staining was not correlated with serum PIVKA-II levels or with the histotogical differentiation of HCC. However PIVKA-II staining tended to be more intense in tissue from patients with portal tumor thrombus, distant metastases, or a longer duration of HCC. CONCLUSION: This method of immunohistochemical staining is easy and simple to use and may be helpful for detecting tissue PIVKA-II in paraffin-embedded HCC specimens.
