Preventive immunization is the cheapest and most effective approach to the management of epidemic disease. Certain forms of cancer, including Burkitt's lymphoma, carcinoma of the cervix, primary liver cancer, acute leukaemia and breast cancer show many characteristics of epidemic disease, and the possibility of producing preventive vaccine against these conditions merits serious consideration.

To make a preliminary determination as to whether a potential health hazard exists for workers exposed to dry cleaning solvents (carbon tetrachloride, trichloroethylene, and tetrachloroethylene), we analyzed the causes of death of 330 deceased laundry and dry cleaning workers by the proportionate mortality method. The increased risk for malignant neoplasms resulted primarily from an excess of lung and cervical cancer and slight excesses of leukemia and liver cancer. Although the number of deaths was small, the increased risk of cancer noted in this investigation underscores the need for additional epidemiologic studies of this occupational group.

Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

We compared age-adjusted mortality rates for cancer of selected sites for Chinese, Japanese, and native Indian residents of British Columbia during the years 1964-73 to the corresponding rates for the white population. Mortality from all cancers of the Chinese did not differ significantly from that of whites. Elevated rates are seen for cancer of the nasopharynx in both sexes, of the liver and esophagus in males, and of the lung in females. Chinese males had a lower mortality than whites from stomach, prostate, and bladder cancer and brain tumors, whereas females had a lower mortality from tumors of the colon, breast, and ovary; both sexes had a lower mortality from leukemia. For Japanese males and females, the mortality rates for all cancers combined were similar to those of the white population. The rates for cancer of the stomach and gallbladder were higher in both sexes; males also showed a higher rate of liver cancer. Prostate and breast cancer mortality rates were lower. Native Indian males had a lower mortality rate from all cancers combined; the difference was significant for stomach, colon, lung, and prostate cancers, and for leukemia. Native Indian females showed a lower rate for ovarian cancer and a higher rate of tumors of the gallbladder and uterine cervix, but their overall cancer mortality was similar to that of whites.

Cancer mortality during 1970-85 of immigrants from East and West Africa and the Caribbean to England and Wales is described. Overall cancer mortality was raised in West African males (RR 1.38, 95% CI 1.25-1.54), and non-significantly raised in West African females (RR 1.14, 0.96-1.37) compared to mortality in the England and Wales-born population. Much of the increased risk was due to very high rates of liver cancer in males (RR 31.6, 23.8-41.9), but rates were also raised for a wide range of other cancers in each sex. Only lung and brain cancer had significantly decreased mortality. In East Africans, overall cancer mortality was low in males (RR 0.63, 0.56-0.70), and in females (RR 0.80, 0.72-0.89). Mortality was significantly low for cancers of the stomach, pancreas and testis, and Hodgkin's disease in males, for cervical cancer in females, and for lung cancer and melanoma in both sexes. Cancer sites with significantly raised mortality included oropharyngeal cancer, leukaemia, and multiple myeloma in both sexes. In Caribbean immigrants overall cancer rates were significantly low in males (RR 0.71, 0.68-0.74) and in females (RR 0.76, 0.73-0.80). Mortality was significantly low for many cancers including colorectal, lung, testis and brain cancers. Mortality was significantly raised only for cancer of the prostate in males, of the placenta in females, and of the liver, non-Hodgkin's lymphoma and multiple myeloma in both sexes. Overall, mortality was high from prostatic cancer and liver cancer, and was low from brain cancer, in predominantly ethnic African immigrant groups. Both East and West African immigrants had raised rates of leukaemia. All of the migrant groups had high rates of multiple myeloma and low rates of testicular, ovarian and lung cancer. Genetic and environmental factors that may contribute to these patterns are discussed.

This study is to calculate a risk of lung cancer in a cohort of 1411 sarcoidosis cases which were followed for a 3 year period from 1984 to 1987. The physicians were requested to answer the questionnaire about progress of the disease by mail. Excess death was investigated using standardized mortality ratio (SMR). The expected number of deaths was calculated from Japanese sex-age specific mortality rate in 1985, using person-year method. Death from all causes and cancers did not show any excess. SMR being 0.98 and 0.97 respectively. The SMR of lung cancer was 3.26 (male: 5.56, female: 3.03), being statistically significant. The SMR of lung infection was 4.2, with statistical significance. The SMR of other main causes of death in Japan i.e., cerebrovascular accident, ischemic heart diseases and heart failure was less than 0.88. It is probably that sarcoidosis is a risk factor of lung cancer. The SMR of leukemia and uterine cancer was 5.88 and 8.70, respectively, though the observed number of leukemia was too small to conclude how high the cancer risk is among sarcoidosis patients. Gastric cancer, hepatic cancer and colon cancers were not observed.

This study was conducted to assess the enhanced antitumor effects of natural human tumor necrosis factor alpha (nHuTNF-alpha) and natural human interferon alpha or gamma (nHuIFN-alpha or -gamma), in combination, on ten human cancer cell lines. The cell lines tested were colon cancer (RPMI4788), lung cancer (PC10), gastric cancer (MKN-1 and MKN-28), nasopharyngeal cancer (KB), leukemia (K562), lymphoma (Daudi), Liver cancer (H-7) and breast cancer (ZR-75-30 and ZR-75-1). A mixture of nHuTNF-alpha and nHuIFN-alpha (1:1, by unit) showed cytotoxic effects on nHuTNF-alpha resistant cell lines such as RPMI4788, KB and Daudi or nHuIFN-alpha resistant cell lines such as KB, and ZR-75-1, as well as on nHuTNF-alpha or nHuIFN-alpha sensitive cells. A synergistic antitumor effect occurred in four cell lines (RPMI4788, PC10, Daudi and ZR-75-1) treated with a combination of nHuTNF-alpha and nHuIFN-alpha. Also, a combined treatment with nHuTNF-alpha and nHuIFN-gamma (1:1/100, by unit) showed cytotoxic effects on nHuTNF-alpha or nHuIFN-gamma resistant cell lines such as MKN-1, MKN-28, Daudi, H-7 and ZR-75-1. A synergistic antitumor effect occurred in eight cell lines (RPMI4788, PC10, MKN-1, MKN-28, KB, Daudi, H-7 and ZR-75-1). Thus, the combined treatment with nHuTNF-alpha and nHuIFN-alpha or -gamma expanded the spectrum of sensitive cells. These results indicate that the combined use of nHuTNF and nHuIFN may provide a certain approach to cancer treatment.

Monoclonal antibodies (MAbs) were obtained from hybridoma clones established by cell fusion between P3X63Ag8.653 mouse myeloma cells and spleen cells of mice or rats hyperimmunized against human bladder cancer tissue or BC47 rat bladder cancer cells. RBS-31 and RBS-85 mouse MAbs and RBA-1 rat MAb were raised against BC47 cells and HBP-1 MAb was raised against human bladder cancer tissues. Urinary antigens detected by these MAbs were quantitatively assayed by means of ELISA using 50 microliters of 1:2 diluted urine samples. The cut-off value of the assay was set up as the mean + 4 X SD of the mean using data from the healthy individual urine samples. The reactivity of all healthy control urine samples were under the cut-off value (negative). By contrast, urine from bladder cancer patients reacted positively with the RBS-31 MAb at 72%, with the RBS-85 MAb at 63%, with the RBA-1 MAb at 51% and with the HBP-1 MAb at 35%. The urine samples from some patients with renal calculi, acute cystitis or complicated urinary tract infections showed only a weak reactivity with our MAbs. As for extra-bladder cancers, some patients with renal, renal pelvis, prostate or ureter cancer, but no patients with esophageal, gastric, colon or liver cancer or leukemia, had reactive urinary antigens.

Work history records and fitness reports were obtained for 1,767 marine inspectors of the U.S. Coast Guard between 1942 and 1970 and for a comparison group of 1,914 officers who had never been marine inspectors. Potential exposure to chemicals was assessed by one of the authors (RP), who is knowledgeable about marine inspection duties. Marine inspectors and noninspectors had a deficit in overall mortality compared to that expected from the general U.S. population (standardized mortality ratios [SMRs = 79 and 63, respectively]). Deficits occurred for most major causes of death, including infectious and parasitic diseases, digestive and urinary systems, and accidents. Marine inspectors had excesses of cirrhosis of the liver (SMR = 136) and motor vehicle accidents (SMR = 107), and cancers of the lymphatic and hematopoietic system (SMR = 157), whereas noninspectors had deficits for these causes of death. Comparison of mortality rates directly adjusted to the age distribution of the inspectors and noninspectors combined also demonstrated that mortality for these causes of death was greater among inspectors than noninspectors (directly adjusted ratio ratios of 190, 145, and 198) for cirrhosis of the liver, motor vehicle accidents, and lymphatic and hematopoietic system cancer, respectively. The SMRs rose with increasing probability of exposure to chemicals for motor vehicle accidents, cirrhosis of the liver, liver cancer, and leukemia, which suggests that contact with chemicals during inspection of merchant vessels may be involved in the development of these diseases among marine inspectors.

To evaluate the effects of continuous low-level ionizing radiation on humans, the follow-up data (1980-85) on Japanese thorotrast-exposed patients were analyzed. The patients were 241 war-wounded military personnel registered with and cared for by the Ministry of Health and Welfare since 1979. During this period, a total of 1144 person-years, 94 patients died. Compared with the expected number of deaths calculated from age- and cause-specific death rates in Japan during the same period, the thorotrast-exposed patients were at three times greater risk of death from all causes (P less than 0.001), had 47 times the risk of liver cancer (P less than 0.001), 12 times the risk of leukemia (P less than 0.05), and 20 times the risk of liver cirrhosis (P less than 0.001). Age at time of thorotrast injection, drinking and smoking habits had little effect on these statistics. Analyses of 30 autopsied patients with liver cancer showed statistically significantly increases in hemangiosarcoma and cholangiocarcinoma. The thorotrast-exposed patients' estimated risk of liver cancer by histological type was 21 times that of the general population for hepatocellular carcinoma, 303 times that for cholangiocarcinoma and 3129 times that for hemangiosarcoma.
