Clinical efficacy of new fluorouridine derivative, FF-705, was studied in 108 patients with advanced malignant tumors. Partial responses were observed in 8 of 61 evaluable cases (13.1%): 4 of 9 patients with breast cancer, 1 of 19 patients with gastric cancer, 1 of 15 patients with lung cancer, 1 of 3 patients with kidney cancer and 1 of 1 patient with pancreas cancer. In the analysis of adverse effects of FF-705, gastrointestinal toxicity was major toxicity. Especially, diarrhea was observed in 41 of 108 patients (38.0%) within a total dose of 10 g shortly after drug administration.

The long-term health effects of exposure to thorium are of interest because of the possible increased use of thorium as an energy source in reactors using 232Th to produce 233U. Mortality is described in a cohort of 3039 men who were employed between 1940 and 1973 at a company involved in the production of thorium and rare earth chemicals from monazite sand. Based on deaths ascertained by the Social Security Administration and mortality rates for U.S. white males, the standardized mortality ratio (SMR) for all causes was 1.05 with 95% confidence limits (95% CL) of 0.96 and 1.15. Much of the excess mortality was attributable to non-occupational motor vehicle accidents (SMR = 1.64; 95% CL = 1.16 and 2.23), but SMRs were also high for lung cancer (1.44; 95% CL = 0.98 and 2.02), pancreatic cancer (2.01; 95% CL = 0.92 and 3.82), and diseases of the respiratory system (1.31; 95% CL = 0.92 and 1.83). In a subgroup of 592 men who worked for at least one year in selected jobs (indicative of highest exposure to thorium and thoron) that was followed up more intensively, the SMR for pancreatic cancer was significantly elevated (i.e. 4.13; 95% confidence limits = 1.34 and 9.63). The SMR for lung cancer was 1.68 (95% CL = 0.81 and 3.09), while that for respiratory diseases was 1.20 (95% CL = 0.52 and 2.37). Information on smoking habits in a sample of survivors suggested that smoking could have explained at least part of the excess mortality from lung and pancreatic cancer and from diseases of the respiratory system. Continued follow-up of the cohort through morbidity and mortality studies is needed to evaluate further the possible long-term effects of exposure to radioactivity and chemicals in the thorium extraction process.

CEA producing cell lines were established from human gastric cancer (HGC-Y1), pancreatic cancer (HPC-Y9) and lung cancer (HLC-Y1). The culture medium was used RPMI-1640 supplemented with 10% fetal bovine serum. The secretion of carcinoembryonic antigen (CEA) into the spent medium from these cultured cell lines was modified by several factors, such as theophylline, cyclic AMP (cAMP), dibutyryl cyclic AMP (dbcAMP), Bromodeoxyuridine (BrdUrd), dimethyl sulfoxide (DMSO), Prostaglandin E2 (PGE2) and human interferon (INF). CEA secretion was enhanced by theophylline, cAMP, PGE2 and INF. Theophylline had an optimal dose to maximally enhance CEA secretion. cAMP and INF apparently enhanced CEA secretion dose dependently. PGE2 appeared to enhance CEA secretion, although cell growth was markedly suppressed dose dependently, dbcAMP, DMSO and BrdUrd did not affect CEA secretion. Here, the kinetics of CEA secretion was discussed.

Two hundred and seventy-one sera from patients with lung cancer were checked to determine whether they exerted a blocking or potentiating effect on normal lymphocyte-cytotoxicity against lung cancer targets using a microcytotoxicity assay. A blocking effect was observed in 15 of 49 untreated patients (30.6%), but a potentiating effect was detected in 10 of 49 (20.4%). Such effects were not correlated with stages of the disease or the clinical status of patients. Such a blocking effect was also detected in patients with pneumonia, pulmonary tuberculosis, benign mediastinal tumor and malignancies other than lung cancer, but the potentiating effect could not detected in such patients. Using an indirect membrane immunofluorescence test, IgG antibodies against QG-56 of a lung cancer cell line were detected in 54.3% of potentiating sera and in 20.5% of blocking sera. Such antibodies were cross-reactive with 2 other lung cancer cell lines and one of 4 uterine cancer lines, however, no cross-reaction was observed against 3 breast cancer lines, 3 of 4 uterine cancer lines, one malignant melanoma line and one pancreas cancer line. The effector cells exerting the potentiating effect were identified as non-adherent, Fc receptor-bearing lymphocytes. Therefore, the potentiating effect might be typical antibody-dependent cell-mediated cytotoxicity.

A cohort of 13,114 workers employed during 1930-1975 in two Swedish plants producing tires and industrial rubber goods was investigated with regard to cancer mortality and cancer incidence. Separate analyses were performed on the following subgroups of the cohort: mixers/weighers, other production workers, and white-collar employees. For all causes of death no increase of risk was observed in the population as a whole. Mixers/weighers showed however an increased overall standardized mortality ratio. The pattern of causes of death was not changed in the total cohort. An increased risk to die from liver cancer (risk ratio 4.12) and pancreatic cancer (risk ratio 2.70) was, however, observed for the category other production workers. An increased risk of death from tumors of the respiratory organs was also observed for the categories other production workers (risk ratio 1.89) and white-collar employees (risk ratio 2.63). For tumors in the urinary bladder (risk ratio 2.50) and for ischemic heart diseases (risk ratio 1.27) the death risk was elevated for the category other production workers. The cancer morbidity pattern showed an increase in malignant melanomas (risk ratio 2.50) for the category other production workers and for lung cancer (risk ratio 2.09), as well as for tumors in the nervous system (risk ratio 3.18) for white-collar employees.

Disseminated intravascular coagulation (DIC) was examined pathologically in 4906 consecutive autopsy cases during the last 11 years. The cases having pathologically confirmed DIC showing microthrombi in three or more organs were 88. Of the underlying diseases for these cases, malignant tumor was found in 40 cases and diseases of hematopoietic organs in 19. Of the cases with malignant tumor, 11 had gastric cancer, 7 had lung cancer, and 4 had pancreatic cancer. Thirty-three of the 40 cases with malignant tumor showed metastasis in two or more organs. Cases with pathologically confirmed or suspected DIC that had microthrombi in one or more organs were 319. As for the incidence of pathologically suggestive DIC in each disease, the incidence of malignant tumor was 7.3% and that for diseases of the hematopoietic organ was 10.6%. Infection is an important underlying condition, especially gram-negative bacillus septicemia which may play an important role in the development of DIC. An increase in the number of white blood cells appears to be one of the causative conditions of DIC. Kidney is involved most frequently by the deposition of microthrombi, and 27 out of 88 cases show ischemic lesions induced by intravascular coagulation. There were 109 cases having clinically diagnosed or suspected DIC, but 67 cases showed no microthrombus formation. On the other hand, 63 among 4,797 cases with clinically unsuspected DIC revealed microthrombus formation in three or more organs by the postmortem examination.

We compared the average annual age-adjusted, sex- and site-specific cancer mortality rates among Kentuckians during two five-year time periods: 1971 to 1975 and 1976 to 1980. Lung cancer alone showed a statistically significant increase in mortality rates for both sexes, but significant increases were also found for skin cancer and leukemias among men and for pancreatic cancer and lymphomas among women. Significant decreases in mortality rates were observed for cancer of the rectum and stomach in both sexes, lymphomas among men, and leukemias and liver and uterine (corpus and cervix) cancer among women. Increased lung cancer mortality rates occurred for all age groups of women aged 35 and over, but in men, decreased lung cancer mortality rates were observed for ages 35 to 49 and increased rates only after age 50. All age groups of women experienced substantial declines in cervical cancer mortality rates. Without the dramatic increase in lung cancer mortality during this period, overall cancer mortality rates would have shown almost no change among Kentucky men and would have decreased among Kentucky women.

The concentrations of N-terminal peptide of type III procollagen in the sera of patients with various cancers were measured by radioimmunoassay. The mean value (with standard deviation) in the control group was 9.9 +/- 2.6 ng/ml. Serum levels exceeding 15 ng/ml were defined as positive, and it was found that 94% of 18 patients with primary liver cancer with cirrhosis, 88% of 8 patients with primary liver cancer without cirrhosis, 77% of 13 patients with metastatic liver cancer, 86% of 7 patients with recurrent breast cancer, 86% of 8 patients with colonic cancer, 75% of 8 patients with pancreatic cancer, 70% of 23 patients with stomach cancer, 51% of 35 patients with lung cancer, and 54% of 28 patients with uterine cancer showed positive levels. The concentrations showed great intersubject variations, probably reflecting the activity of tumor growth and/or invasion. The concentrations in the sera of patients with primary liver cancer with cirrhosis were generally higher than those in patients with liver cirrhosis alone or primary liver cancer without cirrhosis. This result suggested that the growth of primary liver cancer complicated by cirrhosis might be detected by serial measurements of this peptide in the serum of patients with liver cirrhosis. Present data suggested that this peptide is not cancer-specific, but assay of the peptide might be of value as an auxiliary means of detecting and monitoring various cancers, especially liver cancer.

The purpose of this study was to investigate mortality patterns of aluminum reduction plant workers. A cohort was formed of 21,829 workers with five or more years employment in 14 reduction plants. Progress of the study was reported quarterly to a Tripartite Committee consisting of representatives from labor, management and government. Although the results of other studies relative to an excess of lung cancer in aluminum workers were not confirmed, there were indications of a higher than expected mortality in pancreatic cancer, lymphohematopoietic cancers, genitourinary cancer, nonmalignant respiratory disease and benign and unspecified neoplasms.

Among 1,047 women fluoroscopically examined in average of 102 times during pneumothorax therapy for tuberculosis and followed up to 45 years (average = 27 yr), no increase in the total number of cancer deaths occurred when these women were compared to 717 women who received other treatments [relative risk (RR) = 0.8]. However, elevated risks of mortality from stomach cancer (RR = 2.3), rectal cancer (RR = 3.8), breast cancer (RR = 1.2), lung cancer (RR = 1.8), and leukemia (RR = 1.2) were observed, but none was statistically significant and all were based on very small numbers of deaths. These increases were balanced by decreases of genital cancer (RR = 0.2), pancreatic cancer (RR = 0.9), lymphoma (RR = 0.6), and all other cancers (RR = 0.1). Average cumulative absorbed doses were 110 rads for the lungs, 33 rads for the trunk, 13 rads for the active bone marrow, and 7 rads for the stomach. The following upper levels of excess risk could be excluded with 95% confidence: 3.5 deaths/10(6) woman-year (WY)-rad for lung cancer, 4.8 deaths/10(6) WY-rad for lymphoma, and 12 deaths/10(6) WY-rad for leukemia. These findings indicated that the carcinogenic effect of multiple low-dose X-ray exposures was not greater than that currently assumed.
