Polyriboinosinic-polyribocytidylic acid (poly I - poly C), an interferon inducer, was administered in multiple doses of 0.3-75 mg/m2 to 26 patients with a variety of solid tumors, 9 with acute leukemia, and 2 with chronic myelogenous leukemia in blast crisis. Forty-four separate drug trials were comprised of various schedules and routes of administration. Toxic reactions included fever (in 66% of the trials), transient elevation of serum glutamic-oxaloacetic transaminase and serum glutamic-pyruvic transaminase (25%), minimal laboratory evidence of coagulation abnormalities (59%), and hypersensitivity (5%). These toxic manifestations did not relate to dose level or magnitude of interferon induction. Poly I - poly C administered iv induced low serum concentrations of interferon in 24/38 trials (63%), but the correlation between drug dose and peak interferon titer was not linear. Poly I - poly C administered iv or im was not effective as an inducer of interferon in the cerebrospinal fluid. Similarly, poly I - poly C administered im or by inhalation did not produce detectable serum levels of interferon. No patients experienced an objective tumor response to the administration of poly I - poly C, and most (76%) had progression of their disease while receiving the drug.

A case of B cell lymphoma with clinical and histological features of malignant histiocytosis was described. A 57-year-old male was admitted to Shinshu University Hospital because of transverse myelopathy. Five months before admission, he noticed urinary disturbance, which progressed to urinary obstruction. The following month, bilateral muscular weakness appeared in his legs. A few days later he could not stand up, and was admitted to a local hospital. Neurological examination revealed sensory disturbances below the level of Th12 in all modalities, and marked weakness and hyperreflexia in the lower limbs. A spinal tumor was suspected. However, myelography showed no abnormality. The patient's condition worsened and he became bed-ridden in February 1990. He was transferred to Shinshu University Hospital for further evaluation. On admission he was poorly nourished with fever, anemia, hepatomegaly, and bilateral pretibial pitting edema. No lymphadenopathy was observed. Neurological examination showed total sensory loss below the level of Th12, spastic paraplegia, hyperreflexia in the legs, and urinary obstruction. Laboratory findings revealed an elevated erythrocyte sedimentation rate, increased CRP, pancytopenia, and hypoalbuminemia. Serum level of IgG, IgA, IgM, LDH, ALP, GPT and total bilirubin were increased. CSF and MRI imaging of the spinal cord were normal. Proliferation of atypical histiocytes with marked erythrophagocytosis, which is a characteristic pathological feature of malignant histiocytosis, was observed in peripheral blood and aspirated bone marrow. Immunoenzyme staining of bone marrow using monoclonal antibody L-26, which is a B-cell marker, revealed B-cell lymphoma.(ABSTRACT TRUNCATED AT 250 WORDS)

We examined the changes in serum human hepatocyte growth factor (hHGF), also called "scatter factor," levels after transcatheter arterial embolization (TAE) and partial hepatectomy (PH) in patients with hepatocellular carcinoma and metastatic liver tumor. In most cases, the serum hHGF levels increased transiently 1-3 days after TAE or PH, and then decreased nearly to the basal levels in 1 wk, suggesting that hHGF may play an important role in liver regeneration in humans. The mean amount of increase in serum hHGF levels after PH was 0.38 ng/ml, which was greater than that after TAE (0.16 ng/ml). In three cases of TAE followed by PH, two showed a greater increase in serum hHGF levels with PH than with TAE, but the third showed the reverse result. Because the rate of increase in serum ALT levels did not affect that of serum hHGF levels, the degree of liver injury induced by TAE or PH does not seem to be a determinant in serum hHGF elevation.

Nonhematopoietic hepatic neoplasms (n = 25) were diagnosed in 21 cats during a 5.5-year period. Thirteen of the neoplasms were benign bile duct adenomas and 12 were malignant, 6 of which were bile duct adenocarcinomas. All cats were greater than or equal to 10 years old, and 14 were male. Main clinical signs were anorexia and lethargy, and 15 of 21 cats had hepatomegaly. All 21 cats were feline leukemia virus-test negative. Although there was a trend toward high activities of serum alanine transaminase and aspartate transaminase, neither clinical signs nor enzyme activity were specific for diagnosis of hepatic neoplasia in the cats of this study.

Clinical efficacy of IPM/CS against urinary tract infections (UTI) was evaluated on 19 patients with malignancies (bladder tumor: 15, prostate cancer: 3, uterus cancer: 1) and 1 patient with a benign disorder (ureter stenosis) who had undergone ureterocutaneostomy between January, 1988 and December, 1990. Their ages ranged from 42 to 79 years. Postoperatively, they had UTI with pyuria of greater than or equal to 5/hpf and bacteriuria of greater than or equal to 10(4)/ml. IPM/CS was administered at a dose of 0.5 g (0.25g/0.25 g) twice a day through intravenous drip infusion. Its efficacy was evaluated according to the UTI criteria for clinical evaluation as ruled by the Japanese Society of Chemotherapy. Overall clinical value was rated "excellent" in 4 (20%), "moderate" in 9 (45%) and "poor" in 7 (35%) cases for a total of 65%. The efficacy by types of infection was 33% and 70.6% in the group of single infection and in the group of mixed infection, respectively. As to bacteriological efficacy 34 of the 38 strains (89.5%) isolated were eradicated following its administration. The eradication rate was 84.6% for P. aeruginosa, and 84.6% for E. faecalis. Microbes which appeared after its dosing amounted to 6 classes of 17 strains, 6 NFB strains of which were identified. As a side effect, elevation of serum GPT (5%) was noted. Regardless of the underlying conditions (malignant diseases and ureterocutaneostomy), clinical efficacy of IPM/CS was appreciable. In addition, the MIC for (P. aeruginosa, E. faecalis) of IPM/CS was lower than that of PIPC.

During the twenty-nine-year period from June 1959 to October 1988, 32 infants and children with histology-proved hepatoblastoma were seen at the Department of Pediatrics, National Taiwan University Hospital (NTUH). The age at diagnosis ranged from four days to six years, with a mean of one year and eight months. Most of the patients (87.5%) were under the age of three. There was no sex predilection (16 males, 16 females). The most common presenting signs were an upper abdominal mass (71.9%) and/or abdominal distention (62.5%). Physically, all the patients revealed hepatomegaly, with or without mass. Laboratory abnormalities included primarily thrombocytosis (64.3%), elevated serum aspartate aminotransferase (75.0%), serum alanine aminotransferase (62.5%), cholesterol (78.3%) and alphafetoprotein (92.3%). According to the classification of Ishak and Glunz, 56.3% of these belonged to the epithelial type; the others belonged to the mixed type. During the follow-up period, 6 patients with complete resection of the tumor remained alive from 2 years to 17 years and 4 months. Twenty-two patients died from 8 days to 16 months after diagnosis. Four patients were lost to follow-up. The two-year survival rate was 21.4% (6/28). Complete resection of the tumor was the key treatment for achieving survival.

Hepatocellular carcinoma patients were categorized into three grades according to the extent of portal vein invasion by the tumor. Correlations between the extent of portal vein invasion and values of alpha-fetoprotein (AFP), and various biochemical tests were examined. The extent of portal vein invasion by the tumor significantly correlated with the values of glutamic oxaloacetic transaminase (GOT), glutamic oxaloacetic transaminase: glutamic pyrubic transaminase (GOT:GPT), lactic dehydrogenase (LDH), alkaline phosphatase, leucinaminopeptidase (LAP), gamma-glutamic transpeptidase (gamma-GTP) and log10AFP. Results of the multivariate logistic regression analysis showed the values of LAP, LDH, log10AFP and GOT:GPT to be statistically significant independent indicators of portal vein invasion by hepatocellular carcinoma. The calculated probability for portal vein tumor thrombus, which was derived from the results of a step wise multivariate logistic regression procedure, revealed high accuracy and specificity for predictability. To design effective therapy and to predict the prognosis, it would be beneficial to obtain additional information from this calculated probability in patients with hepatocellular carcinoma.

Eighty-three patients with primary liver cancer (PLC) having survived over 5 years were investigated. 50.6% (42/83) of them were in Stage I and 49.4% (41/83) were in Stage II. Resection was performed in 94.0% (78/83), and hepatic artery ligation and/or cannulation was done in 6.0% (5/83). By the end of March 1990, 66.3% (55/83), were cancer-free, 4.8% (4/83) were living with the cancer, 20.5% (17/83) died from recurrence or metastasis of cancer, 7.2% (6/83) died from liver failure, and 1.2% (1/83) lost followup. 29 cases survived over 10 years after resection of PLC. A comparison with 811 patients having less than 5 years during the same period demonstrates that early discovery, lower gamma glutamyl transpeptidase (gamma-GT) and alanine aminotransferase (ALT), tumor less than or equal to 5 cm, single nodule, well-encapsulated tumor, radical resection, and alpha fetoprotein (AFP) normalization after resection may contribute to prolonged survival. It is concluded that early detection and early radical resection are essential to improve the therapeutic effects.

This study of hepatocellular carcinoma in a homogeneous rural Transkeian population at high risk consisted of: evaluation of liver biopsies of 246 patients with hepatocellular carcinoma using routine histology and immunoperoxidase for HBV stains; collection of reliable data on alcohol consumption, blood HBsAg and ALT status in asymptomatic controls from an adequate population sample; assessment of maize intended for human consumption for contamination by carcinogenic fungi. Tumour histology of rural Blacks did not differ from those described in other studies. Cirrhotic livers were present in 45.1% and iron overload in 68% of cases. Tissue HBsAg was detected in 57% (45% of non-cirrhotic and 59% of cirrhotic livers). Asymptomatic controls showed 9.5% of HBsAg positivity, 3.5% had elevated ALT and 41.3% admitted to alcohol abuse. Maize had insignificant contamination by Aspergillus flavus and very frequent contamination by Fusarium moniloforme. This study suggests a multifactorial aetiology of hepatocellular carcinoma, with viral infection being of the most importance.

To determine serum thyroxine-binding globulin (TBG) levels, we used radioimmunoassay, and compared the results obtained with other tests in 231 patients with chronic hepatitis B virus infection to evaluate its clinical implications. All of these patients were hepatitis B surface antigen (HBsAg)-positive. Among them, 38 patients had hepatocellular carcinoma (HCC), 18 had chronic persistent hepatitis, 70 had chronic lobular or active hepatitis (grouped as CAH), 31 had active cirrhosis (AC), 25 had inactive cirrhosis, 20 had decompensated cirrhosis, and 29 were "healthy" HBsAg carriers. Twenty-seven patients with acute hepatitis, 12 with cancer metastasis to the liver, and 81 normal adults served as disease or normal controls. The results showed that serum TBG level increased significantly in patients with CAH, AC, or HCC. Serum TBG did not correlate with albumin or bilirubin level, but correlated with alanine aminotransferase (ALT) positively in patients with CAH (p less than 0.001) and negatively in patients with HCC (p less than 0.01) (slope difference p less than 0.05). Serial determination of serum TBG and ALT also showed parallel changes in 15 patients with CAH, but not in nine patients with HCC. In contrast, the fall and rise of serum TBG levels in patients with HCC coincided with tumor resection and recurrence. The data suggest that serum TBG elevation in patients with hepatitis activity is the result of hepatocellular damage, whereas that in patients with HCC is due to increased synthesis. Whether serum TBG elevation without concomitant rise of ALT could be used as a marker of HCC awaits further study.
