Analyses of the prognoses of thirty-four patients with hepatocellular cancer, who were treated by hepatic arterial infusion chemotherapy and/or transcatheter arterial embolization (TAE) and/or hyperthermotherapy, were performed by multivariate analysis using Cox's proportional hazard model and generalized Wilcoxon test. In the multivariate analysis on the conditions of patients, nine of fifteen variables were associated with the prognosis of patients who received regional cancer chemotherapy. The variables are: sex, liver cirrhosis, esophageal varices, GOT, GPT, albumin and gamma-globulin. One of three variables was associated with the prognosis in the therapy analysis, and the variable is TAE. Significant differences in survival curves which were estimated by generalized Wilcoxon test were noted in age, portal vein invasion, ascites, GOT and TAE. From these results it is suggested that the conditions of patients with unresectable hepatocellular cancer must be carefully investigated before regional cancer chemotherapy and the good therapy effects is obtained by hepatic arterial infusion chemotherapy combined with transcatheter arterial embolization therapy.

Forty-two patients with small cell lung cancer were treated with a combination of carboplatin, ifosfamide and etoposide. Vincristine was given on day 14 of each course, the courses being repeated every 28 days for a maximum of six. Thoracic radiotherapy was given 4 weeks after the last course of chemotherapy but no prophylactic cranial radiotherapy was administered. Thirty patients had clinically limited state disease, the remaining patients having contralateral neck lymphadenopathy and/or pleural effusions. Elevated enzyme levels (alkaline phosphatase, LDH, ALT, GGT) were noted in 69% of patients. Twenty-four patients (57%) achieved a complete response (CR) when assessed one month after the end of treatment. A further 21% of patients had a partial response (PR). Median duration of CR was 14 months and of PR 8 months. Cerebral metastases were the sole site of relapse in 13% of the CR patients. Myelosuppression was severe with a median nadir of neutropenia of 0.2 x 10(9) cells 1-1. However, 74% of the patient group received all six courses of chemotherapy and only 16 courses (7%) were delayed because of toxicity. There were three deaths associated with treatment-related neutropenia. The median survival of the total group was 14 months, with an actuarial 2 year survival of 37% and a minimum follow-up of 18 months. [A recent analysis, March 1989, demonstrated a 33%, 2 year actual survival.]

All cases of liver tumor referred to the King Faisal Specialist Hospital and Research Centre in Saudi Arabia during 2.5 years were reviewed. Hepatocellular carcinoma, 104 cases, was considerably more common than metastatic carcinoma with unknown primary, 15 cases. Lymphoma presenting as liver tumor occurred in three cases and there were no cases of cholangiocarcinoma. There were only two cases of benign tumor, both hemangioma. Hepatocellular carcinoma was characterized by a male predominance of 6:1, positive hepatitis B surface antigen in 60%, presentation with an enlarged, hard liver in over 90%, a systolic-diastolic bruit over the mass in 45%, a single highly echogenic lesion in the right lobe on ultrasound in 80%, and rapid progression. The serum AST (aspartate aminotransferase, serumglutamic oxalacetic transaminase [SGOT]) was abnormal in 97% and was higher than the alanine aminotransferase (ALT) in 93% of cases compared with 17% in 100 consecutive cases of chronic active hepatitis. Sixty-six percent of patients with hepatocellular carcinoma had serum AFP greater than 200 ng/ml. Excluding five cases of germ cell tumor (none involving the liver), and pregnant patients, serum AFP was less than 200 ng/ml in all other patients in whom it was measured between 1979 and 1981. A practical approach to the diagnosis of hepatocellular carcinoma is outlined. Biopsy does not appear to be indicated in many cases of advanced hepatocellular carcinoma.

In the present investigation, administration of a single i.p. dose of the anticancer drug merbarone [5-(N-phenylcarboxamido)-2-thiobarbituric acid] produced an acute and reversible decrease in renal function in female but not male Fischer 344 rats. The renal lesion in female rats was biochemically characterized as a decrease in p-aminohippuric acid accumulation by renal slices along with polyuria, glucosuria, proteinuria, and enzymuria. These functional changes were accompanied by histopathologic changes of focal tubular necrosis that was confined to the deep cortex and outer stripe of the outer medulla. The changes in these parameters were dose-dependent and were observed at doses as low as 0.2 x MELD(10) (12 mg/kg). This low merbarone dose increased urinary glucose and protein excretion by 26- and 9-fold, respectively, in the initial 16-h urine collection in female rats. This increase was accompanied by a 2- to 15-fold increase in the excretion of N-acetyl-beta-D-glucosaminidase (NAG), gamma-glutamyl transpeptidase (gamma-GTP), and lactate dehydrogenase (LDH) activities. No significant changes in renal function were observed in male rats apart from mild enzymuria after a high dose of merbarone (36 mg/kg). The drug did not increase urea nitrogen levels in male or female rats, reflecting the focal nature of this tubular lesion. Merbarone produced small elevations in serum transaminase activities [i.e., glutamic-oxalacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT)] at doses that produced marked alterations in renal function in female rats, suggesting only mild hepatotoxicity. The present study establishes the kidney as a possible dose-limiting target organ for merbarone toxicity.

In patients with chronic circulatory insufficiency, chronic nonspecific diseases of respiratory system, lung malignancies, as well as in the group of patients with "other diseases" complicated by bacterial pneumonia the total protein and protein fractions, bilirubin, activity of alanine aminotransferase and of aspartate aminotransferase in the blood serum has been determined. The control group consisted of analogous groups of patient without, however, bacterial pneumonia. It has been stated that in patients with lung cancer bacterial pneumonia has been accompanied by the increased concentration of beta-globulin and the decreased concentration of gamma-globulin. In other groups of patients the lowered concentration of albumin and the increased concentration of alpha-globulin has been observed. Chronic nonspecific diseases of respiratory system were, moreover, characterized by the increased concentration of gamma-globulin. In some groups of patients with secondary bacterial pneumonias if compare with analogous++ groups of patients without pneumonia the increased bilirubin concentration and increased activity of alanine aminotransferase and/or aspartate aminotransferase remaining however within normal range has been demonstrated.

Neopterin is a pyrazino-pyrimidine compound which is biosynthesized by macrophages. Increased concentrations of neopterin have been reported in conditions causing a stimulation of cellular immunity, such as viral and other infections, graft versus host disease, autoimmune disease and different malignancies. Recently, urinary neopterin levels have been found increased in patients with acute viral hepatitis and NANB chronic hepatitis. In the present study, neopterin serum levels have been measured in 23 cirrhotic patients (6 HBV related, and 17 cryptogenetic cirrhosis, 7 of them occurring in alcoholic subjects) and in 24 normal subjects. Mean values of serum neopterin were significantly increased in cirrhotics (3.92 +/- 3.28 ng/ml versus 1.24 +/- 0.51 ng/ml in controls, p less than 0.01). Serum neopterin values were not found to be significantly different in cirrhotics assessed in three different clinical classes according to Child's classification and in cirrhotics with and without serological findings of active disease. In fact, in cirrhotic patients, serum neopterin levels did not correlate with the values of serum AST, ALT, ALP, GGT and gamma-globulin. These data show that increased levels of serum neopterin occur in cirrhotic patients, but there is no relation between serum neopterin values and the activity or the clinical severity of the disease. The results are consistent with the hypothesis that activated macrophages are involved in all stages of liver cirrhosis irrespective of its aetiology.

Circulating immune complexes (CIC) were measured at the time of diagnosis in 81 patients with acute leukemia or blast crisis of chronic myeloid leukemia using precipitation by 3.75% polyethyleneglycol. Elevated CIC levels did not adversely influence complete remission duration and survival, patients with normal CIC levels exhibited mostly shorter remission and survival than those with elevated or borderline levels. No significant correlation was observed between CIC levels and Hb, WBC, CBC, platelet count, age, serum bilirubin, total protein, fibrinogen, AST and ALT levels, presence of hepatosplenomegaly and/or lymphadenopathy, HbSAg positivity, complete remission duration and survival. The lack of correlation may be caused by altered immune response in leukemic patients, but the obtained results may also be affected by the nonspecific nature of the method used for the detection. Simultaneous detection of CIC levels by multiple tests and evaluation not only of the number but also of the composition and size of CIC may decrease the incidence of false results. Nevertheless, only the establishment of antigen-specific assays may resolve the controversies in the detection of CIC and thus contribute to a more precise assessment of the role of CIC in prognosis of cancer, as well as to the verification of reliability of using CIC as a tumor marker.

Linkage analysis was conducted in 17 families identified by the familial occurrence of breast and ovarian cancer using a series of 17 serologic and biochemical markers. Lod scores suggestive of linkage of breast/ovarian cancer susceptibility to the RH blood group locus on chromosome 1p were obtained. When the presence of fibrocystic disease of the breast in a first-degree relative of an affected family member was added as an indicator of susceptibility, the evidence for linkage increased. No evidence of linkage to GPT or ABO, both previously suggested to be linked to breast cancer susceptibility, was seen in this study.

The influence of selenium on cis-diamminedichloroplatinum(II) (c-DDP) nephrotoxicity in mice and rats was assessed, using single doses of both compounds. Sodium selenite, 2 mg of selenium per kg, given 1 h before c-DDP, greatly reduced blood urea nitrogen and creatinine levels and morphological kidney damage in both BALB/c mice and Wistar rats, while administration 1 h after c-DDP did not. Liver toxicity of selenium was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase and by routine histology. No liver damage was observed in animals treated with sodium selenite, 2 mg of selenium per kg, and physiological saline or c-DDP. Pretreatment with sodium selenite did not reduce the antitumor activity of c-DDP against MPC 11 plasmacytoma or Prima breast tumor in BALB/c mice. The present results indicate that sodium selenite may provide protection against c-DDP nephrotoxicity, when it is given before c-DDP. Moreover, selenium has an antineoplastic activity against several tumors. The combination of these qualities may open new perspectives in cancer chemotherapy.

Growth of a highly-deviated ascites hepatoma (Yoshida AH-130) in rats caused initial hyperplastic enlargement of the liver, followed by progressive reduction to a size lower than that seen in controls. The time-course of this biphasic change in liver weight roughly corresponded to the exponential and stationary phases of tumour growth. Histologically, scattered small foci of perilobular necrosis were observed during the hyperplastic phase and these were consistently associated with a moderate elevation of glutamate-pyruvate transaminase (GPT) activity in the blood plasma. By contrast, signs of necrosis were absent and plasma GTP levels had returned to normal during the phase of hepatic involution, which was characterized by enhanced apoptosis, a type of single-cell death known to be involved in the regulation of tissue size under both normal and pathological conditions. Biochemically, alterations in liver protein mass resulted from changed rates of tissue protein degradation. The apoptotic bodies could either be lost from the liver via blood, lymph and bile, or phagocytosed and degraded by adjacent cells. Disposal of the apoptotic bodies is likely to account, at least in part, for the enhanced rates of liver protein turnover that characterize hepatic involution.
