Twenty patients with focal malignant obstruction of the major bile ducts (6 cholangiocarcinoma, 8 colorectal, 3 hepatoma, 2 unknown primary, and 1 gastric cancer) were treated on a protocol examining the toxicity and efficacy in relieving jaundice of external beam radiation therapy (4500 cGy in 300 cGy fractions) combined with continuous hepatic arterial (15 patients) or peripheral venous (5 patients) fluorouracil infusion. Toxicity of this regimen consisted of anorexia with mild nausea and vomiting in 55% of patients and gastric ulceration (responsive to medical management) in 15% of patients. One patient exhibited transient grade 2 hepatic toxicity and one had asymptomatic grade 4 leukopenia. Of 14 patients treated without prior biliary drainage, 8 exhibited a decrease in bilirubin levels from a mean of 14.5 mg/dl to 1.5 mg/dl. Four of six patients with biliary drainage catheters at the start of treatment were able to have them removed without reobstruction. For the 8 responding patients among those who did not have cholangiocarcinomas, the median response duration was 5 months with a median survival from treatment of 6.5 months. For the 4 responding patients with cholangiocarcinoma, the median response duration was 16 months with a median survival from treatment of 20 months. All responders did not have a return of jaundice due to reobstruction of the major ducts (until death or to the present). All responders who have died did so due to tumor progression outside of the treated field except for one who died of unrelated causes. The mean number of proven or presumed episodes of cholangitis per patient was virtually identical in those without (1.8) and those with stents/tubes (1.4, p = 0.561). This regionally focused combined modality cytotoxic therapy was able to relieve obstruction in the majority of patients without excess morbidity (including a lack of any detectable increase in sepsis). Thus, it appears feasible to consider randomized studies of this cytotoxic approach versus standard mechanical drainage procedures to define the relative risks and benefits of each.

A retrospective cohort study was carried out in 1982-1983 among 28,460 benzene-exposed workers (15,643 males, 12,817 females) from 233 factories and 28,257 control workers (16,621 males, 12,366 females) from 83 factories in 12 large cities in China. All-cause mortality was significantly higher among the exposed (265.46/100,000 person-years) than among the unexposed (139.06/100,000 person-years), as was mortality from all malignant neoplasms (123.21/100,000 versus 54.7/100,000, respectively). For certain cancers, increased mortality was noted among benzene-exposed males in comparison with that among unexposed males; the standardized mortality ratios (SMR) were elevated for leukemia (SMR = 5.74), lung cancer (SMR = 2.31), primary hepatocarcinoma (SMR = 1.12), and stomach cancer (SMR = 1.22). For females only leukemia occurred in excess among the exposed. Risk of leukemia rose as duration to exposure to benzene increased up to 15 years, and then declined with additional years of exposure. Leukemia occurred among some workers with as little as 6 to 10 ppm average exposure and 50 ppm-years (or possibly less) cumulative lifetime exposure (based on all available measurements for the exposed work units). Among the 30 leukemia cases identified in the exposed cohort, the proportion of subjects with acute lymphocytic leukemia was substantially lower and the proportion with acute nonlymphocytic leukemias was higher than in the general population. During 1972 to 1981, the annual incidence of leukemia ranged from 5.83 to 28.33 per 100,000 with higher rates occurring in the interval 1977 to 1981 than in the earlier years of the study period.(ABSTRACT TRUNCATED AT 250 WORDS)

Sixty-eight patients with various malignancy was examined for their natural killer (NK) cell activity against 14 target cell lines. The group consisted of 10 patients with gastric cancer, 10 patients with lung cancer, 8 patients with hepatoma, 11 patients with cancer of female genital organs, 14 patients with malignant lymphoma and 15 patients with acute myelogenous leukemia (AML). The target cells from a variety of lineage were selected to examine the disease-related specificity in NK cell activity. The peripheral mononuclear cells from patients with gastric cancer did not show a decrease in NK activity against 14 targets including gastric cancer cell lines. Other patients except for AML demonstrated low NK activity against one or two target cells out of 14 targets. Whereas, NK activity in patients with AML was remarkably depressed against 10 target cells out of 14. At single cell assay, killing ability rather than binding activity to target was markedly impaired in AML. Comprehensively, the data demonstrated the marked difference in the NK level between the patients with solid tumor and the patients with hematopoietic malignancy. There existed neither disease-related specificity in NK cytolysis, nor correlation in NK levels and clinical severity in the patients with malignancy. These results suggested that it was very difficult to evaluate the anti-cancer capacity in patients with malignancy by NK activity alone.

During the last 6 years, 205 patients with primary hepatocellular carcinoma (HCC) were admitted to our surgical departments. Thirty-eight had HCC smaller than 3 cm in diameter. There were 34 men and 4 women with an average age of 56.5 years. All patients had underlying hepatic disease: liver cirrhosis in 35 patients and chronic active hepatitis with fibrosis in the remaining 3. Pre-operative complications included: oesophageal varices in ten, cholelithiasis in five, peptic ulcer in two, gastric cancer in one, and severe hypersplenism in one instance. A radical resection was performed in 32 cases and palliative resection in 6. Simultaneous operations were carried out for the above mentioned associated conditions: distal splenorenal shunt in six, Hassab's devascularization procedure in one, splenectomy in one, cholecystectomy in four, cholecystolithotomy in one, and partial gastrectomy in one. Four patients had postoperative complications: liver failure, rebleeding, right haemothorax, and upper gastrointestinal bleeding from acute mucosal lesion of the stomach. One patient with liver failure died in coma within 1 month. The operative and in-hospital mortality rates were 2.6 and 7.9 per cent, respectively. Survival rates during the first 4 years in 32 patients with radical hepatic resection were 89.9, 67.2, 58.8, and 58.8 per cent, respectively. We suggest that hepatic resection should be the first choice of treatment for minute HCC even in the presence of liver cirrhosis.

A case of triple cancer involving a tubular adenocarcinoma of the stomach, a squamous cell carcinoma of the esophagus, and hepatocellular carcinoma of the live is reported. These three cancers had been diagnosed while the patient was alive and later were confirmed by autopsy. The esophageal cancer and hepatocellular carcinoma were found almost simultaneously, 6 years after surgery for the gastric cancer. Although many cases of triple cancer have been reported, a triple cancer of this combination is very rare (0.3% of all cases of triple cancer), our case being the fifth such case in Japan.

The present study establishes the in vitro system for studying the oncosuppression activity of parvovirus and discovers that parvovirus H-1 can be grown cytolytically in various human cancer cell lines, which include 4 hepatoma cell lines (QGY-7703, SMMC-7721, Bel-7402, PLC/PRF/5), 3 gastric cancer cell lines (SGC-7901, MGC-80-3, MKN-28) and 1 naspharynx cancer cell line (CNE). The growth of two primary gastric cancer cell cultures from surgical cancer tissue were also inhibited by the infection of H-1. The sensitivity of cancer cells to H-1 may relate to their differentiation states. On the contrary, H-1 can neither be grown cytolytically in normal liver or stomach cells, nor inhibit their growth. Transformation of human skin fibroblasts with Simian Virus 40 activated their sensitivity to H-1. Our results thus indicate that the antineoplastic activity of H-1 in vivo involves at least its direct inhibiting or killing malignant cells.

Ascitic fluid from tumour patients (hepatoma, gastric cancer, gallbladder cancer, colorectal cancer, ovarian cancer) and from non-malignant diseases (liver cirrhosis, congestive heart failure) were compared with respect to their content of determinants of the fibrinolytic system, tissue-type plasminogen activator antigen (t-PAag) and activity (t-PAact), urokinase-type plasminogen activator antigen (u-PA) and plasminogen activator inhibitor activity (PAI). Furthermore, SDS-polyacrylamide slab-gel electrophoresis (SDS-PAGE) was performed to evaluate molecular weight distribution of the detectable fibrinolytic parameters. In malignant ascites, PAI activity was three to four times higher, and increased complex formation of PAI with t-PA could be demonstrated, compared with non-malignant ascitic fluid. Tissue-type plasminogen activator antigen and activity showed a similar concentration in ascites of both study groups. Urokinase-type plasminogen activator antigen was detectable neither in ascites of malignant nor in ascites of non-malignant origin. It is concluded that t-PA is the physiological plasminogen activator in ascites and that increased PAI levels followed by increased complex formation between t-PA and PAI might reflect a reaction of the peritoneum.

Four patients with histologically confirmed parasellar metastases are reported. The main symptoms and signs were persistent right facial pain followed by diplopia (patient 1), headache and minimal right abducens palsy (patient 2), acute, total left ophthalmoplegia (patient 3), and acute, total bilateral ophthalmoplegia (patient 4). Positive radiologic evidence was present only in patient 1: there was bony erosion of the petrous apex and computed tomography scan showed an enhanced parasellar mass. This patient underwent partial surgical removal of the tumor. Patient 3 was treated with irradiation. All patients died within 14 weeks of the onset of the initial symptoms and all were autopsied. Their primary lesions were hepatoma, stomach cancer, lung cancer, and mesenteric liposarcoma.

A case of hepatocellular carcinoma with metastasis to the stomach and hyperlipidemia as a paraneoplastic syndrome was presented. The patient, a 69-year-old man, was admitted to Kurobe City Hospital with a complaint of epigastralgia. He was diagnosed as having hepatocellular carcinoma by an increased plasma AFP and the abnormalities of hepatic scintigram and abdominal angiography. Endoscopic examination of the stomach revealed an ulcerative lesion suggesting Borrmann type 2 gastric cancer and the gastric mucosal biopsy was interpreted as tubular adenocarcinoma. At autopsy, the liver was enlarged and weighed 4,170 g without liver cirrhosis. Histologic finding of the liver tumor was hepatocellular carcinoma of Edmondson's grade 2 and the gastric tumor with bile production was identical to that of liver tumor. The tumor architecture of the stomach, however, was mixed with trabecular pattern and tubular pattern near the site of gastric mucosa, and was concordant with the findings of gastric mucosal biopsy. Multiple tumor thrombi in the portal system suggested that hepatocellular carcinoma retrogradely metastasized to the stomach through the portal system.
