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.

Cancer risk for farmers in Denmark and Italy was studied by linking occupational census data with incidence of cancer in Denmark and with cancer mortality in Italy. Farmers in the two countries had a consistent risk reduction for cancer of the lung, bladder, small intestine, colon, rectum, and prostate. No excess of stomach cancer was found among farmers in the two countries, which is in agreement with the most recent data from other surveys. The risk of oesophageal cancer was reduced among the Danish and increased among the Italian male farmers. This can probably be explained by differences in alcohol consumption between the Danish and Italian farmers compared with the general population. The risk of brain cancer was significantly reduced among Italian farmers. There was a significant risk reduction for Hodgkin's disease and no excess for non-Hodgkin's lymphoma in Denmark, whereas in Italy a statistically significant excess risk was found for the first and a slight excess risk for the second of these diseases. The per capita consumption of phenoxy-herbicides between 1950 and 1970 was lower in Italy than in Denmark but treatments were performed mainly by professional applicators in Denmark and by the farmers themselves in Italy. Risk of leukaemia among Italian female farmers was increased. In Denmark, this increase was limited to women who were themselves owners of a farm. Specific occupations in agriculture showing a high risk for cancers of the lymphopoietic system in Denmark mostly entailed contact with animals.

An historical cohort study was conducted among 4,213 men who worked for 5 or more years at a Soderberg aluminum reduction plant in British Columbia (BC), Canada. Standardized mortality and incidence ratios were used to compare the mortality and cancer incidence of the cohort with that of the BC population and to examine risk by cumulative exposure to coal-tar pitch volatiles (CTPV) and electromagnetic fields. Significantly elevated rates were observed for bladder cancer incidence (standardized incidence ratio [SIR] = 1.69) and brain cancer mortality (standardized mortality ratio = 2.17). The risk of bladder cancer was strongly related to cumulative exposure to CTPV (P less than .01). The risk for non-Hodgkin's lymphoma also increased with increasing exposure (P less than .05), although the overall rate was similar to that of the general population (SIR = 1.06). The lung cancer rate was as expected (SIR = 0.97), but showed a weak association with CTPV exposure that was not statistically significant. No individual cause of death or incident cancer site was related to exposure to electromagnetic fields. Analysis of the joint effect of smoking and CTPV exposure on lung and bladder cancer showed the exposure response relationships to be independent of smoking.

Previous New Zealand case-control studies have found increased risk for leukaemia, non-Hodgkin's lymphoma (NHL) and multiple myeloma in farmers. We report here a further series of New Zealand Cancer Registry based case-control studies of farming and site-specific cancer risks. These involved 19,904 males aged 20 years or more who were registered with cancer between 1980 and 1984. For each cancer site, the registrations for other sites formed the control group. Farmers had elevated risks for malignant melanoma (Odds Ratio [OR] = 1.25, 95% confidence interval [Cl] 1.05-1.50), and for cancer of the lip (OR = 2.43, 95% Cl 1.81-3.27), rectum (OR = 1.19, 95% Cl 1.03-1.38), bone (OR = 1.95, 95% Cl 1.00-3.80), prostate (OR = 1.26, 95% Cl 1.13-1.41) and brain (OR = 1.34, 95% Cl 1.04-1.74). Decreased risks were observed for cancer of the larynx (OR = 0.66, 95% Cl 0.45-0.96), lung (OR = 0.70, 95% Cl 0.63-0.77) and testis (OR = 0.58, 95% Cl 0.39-0.88). Livestock farmers had a relatively high risk for brain cancer, while the risk for cancer of the lip was highest among dairy farmers. Farmers also had increased risks for cancer of the lymphatic and haematopoietic system (International Classification of Disease 9th edn (ICD) 200-208) (OR = 1.24, 95% Cl 1.08-1.42), leukaemia (OR = 1.24, 95% Cl 0.99-1.55) and non-Hodgkin's lymphoma (NHL) (OR = 1.24, 95% Cl 0.99-1.56), as described previously.

Cancer incidence among 8,004 patients hospitalized for epilepsy between 1933 and 1962 in the Filadelfia treatment community in Denmark was compared to that of the general population. Patients received powerful and prolonged treatment with phenobarbital, phenytoin, and other anticonvulsants. This new survey extends the follow-up from 1976 through 1984. Among 7,864 patients with epilepsy not known to have received radioactive Thorotrast, record linkage with national cancer incidence files identified 789 cancers, compared to 664 expected [relative risk (RR) = 1.19; 95% confidence interval = 1.11-1.27]. Significant risks were found for cancers of the brain and central nervous system (RR = 5.7; n = 118) and the lung (RR = 1.4; n = 106). The excess numbers of brain cancer were concentrated within 10 years of hospitalization (RR = 20.7; n = 80) and decreased significantly over time, which suggests that brain tumors account for the seizure disorder and are not due to phenobarbital exposure as suggested by some epidemiologic studies. No overall risk was apparent when brain cancers were excluded (RR = 1.03). Because bladder cancer was significantly decreased (RR = 0.6; n = 18), the excess risk of lung cancer may not have been related to the "anecdotal" heavy smoking reported among confined groups of epileptic patients in the early years of the study period. The incidence of malignant melanoma was also significantly low (RR = 0.5; n = 7), which suggested limited exposure to sunlight among confined patients. The risk of non-Hodgkin's lymphoma was increased, but not significantly (RR = 1.4; n = 16), which is interesting in view of previous reports suggesting an association with phenytoin. Overall, these data provide little evidence that phenobarbital and phenytoin are carcinogenic to humans, but the excess risks of lung cancer and non-Hodgkin's lymphoma among epileptic patients in our study deserve further evaluation.

The mortality experience of agricultural extension agents in the Cooperative Extension Service (CES) of the U.S. Department of Agriculture who died during the period January 1, 1970-December 31, 1979 (n = 1,495 white males) was evaluated in proportionate-mortality and case-control studies. The proportionate-mortality analysis was used to identify cancers that might be elevated in this occupational group compared with the U.S. white male population. All cancers with a significantly elevated proportionate-mortality ratio were more thoroughly evaluated in the case-control study, where there is presumably less of a selection bias in the comparison. In the case-control study, leukemia demonstrated a statistically significant linear trend with duration of employment as an extension agent. Smaller, but nonsignificant, trends were seen for non-Hodgkin's lymphoma, multiple myeloma, and brain cancer. The odds ratio for Hodgkin's disease and cancers of the colon, prostate, and kidney did not vary with the number of years on the job. These patterns resemble cancer risks seen among farmers, suggesting that agricultural factors may also play a role in the origin of these tumors among extension agents.

We calculated 5-year crude and relative survival rates, by age and sex, for patients in Alberta in whom cancer was diagnosed between 1974 and 1978. Cancers with low overall 5-year relative survival rates (less than 35%) included stomach cancer, cancer of the pancreas, lung cancer, brain cancer, multiple myeloma and myeloid leukemia. Cancers with high overall 5-year relative survival rates (more than 70%) included melanoma, breast cancer, cancer of the uterus, cancer of the bladder and Hodgkin's disease. Five-year relative survival rates were generally lower in the highest age group (75 years or more). A strong inverse relation between age and survival was noted for brain cancer, non-Hodgkin's lymphoma, Hodgkin's disease and myeloid leukemia.

The risk of developing a second primary cancer was evaluated in approximately 19,000 persons with initial cancers of the lymphatic and hematopoietic system in Connecticut between 1935 and 1982. Significant excesses for all second cancers were observed among patients with leukemia (34%), Hodgkin's disease (70%), non-Hodgkin's lymphoma (25%), and multiple myeloma (24%). In general, the risk of second cancers was greater in males than in females, even for cohorts not showing an excess of surveillance-related prostate cancer. Among patients with leukemia, significant excesses of cancers of the lung, kidney/ureter, and prostate were noted; cutaneous melanoma was elevated only in males. These excesses did not persist in the small number of long-term survivors. Possible etiologic factors included tobacco smoking for lung and kidney cancers, medical surveillance artifact for prostate cancer, and immunosuppression for malignant melanoma and lung cancer. The large number and good prognoses of patients with chronic lymphocytic leukemia strongly influenced the pattern of second cancers when all leukemias were analyzed together; no evidence was found for an increased risk of second cancer in patients with acute lymphocytic leukemia. A disproportionate number of subsequent cancers, particularly those of the kidney and ureter, were diagnosed incidentally at autopsy. Patients with Hodgkin's disease displayed significant excesses of cancers of the buccal cavity and pharynx, lung, female breast, and thyroid. The latter 3 sites remained significantly elevated in long-term survivors (10 yr or more postdiagnosis), so that radiation therapy may have contributed to their development. Among persons with non-Hodgkin's lymphoma, cancers of the stomach, lung, brain, and connective tissue occurred excessively. The first 3 sites, plus cancers of the urinary bladder, remained elevated among long-term survivors. The brain cancer excess, not previously reported, may represent misclassification of central nervous system lymphoma. The risk of gastric cancer is reminiscent of similar findings in patients with both acquired and genetically determined immunodeficiency disorders. The alkylating agent, cyclophosphamide, used extensively in the treatment of non-Hodgkin's lymphoma, is known to cause bladder cancer in man.(ABSTRACT TRUNCATED AT 400 WORDS)

Despite their generally favorable mortality experience, general occupational surveys of farmers suggest they have elevated risks of cancer of the lymphatic and hematopoietic systems, stomach, prostate, brain, and skin. Since farmers often serve in the role of mechanic, carpenter, welder, pesticide applicator, and veterinarian, they may be exposed to many potentially hazardous substances. The types and levels of exposures have been discussed by others earlier in the program. The evidence is strongest for the association between farming and risk of leukemia. However, the specific leukemogenic agent or agents have yet to be identified. Leukemia excesses among poultrymen and dairy farmers suggest involvement of zoonotic viruses, while associations with crop production is more indicative of pesticide usage. The associations regarding other cancers (i.e., Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, soft-tissue sarcoma, and cancers of the stomach, brain, and prostate) are even less clear. However, the Swedish reports of high risk of soft-tissue sarcomas and lymphomas among persons exposed to herbicides is particularly disconcerting and underscores the urgent need for similar epidemiologic studies in the U.S. Several case-control interview studies are underway that should help clarify the role of agricultural factors in the origin of various cancers. NCI is sponsoring studies of leukemia and non-Hodgkin's lymphoma among men from Minnesota and Iowa. Detailed information on farm practices and pesticide usage is being gathered. A study of soft-tissue sarcoma, Hodgkin's disease, and non-hodgkin's lymphoma also has just been initiated. This investigation is located in Kansas, a major wheat producing area. A wheat producing area was selected because herbicides are more heavily used on this crop than insecticides. The major objective of this project is to evaluate the role of herbicides in the origin of these cancers. A case-control study of brain cancer has also recently been initiated. Although this study focuses on contact with petrochemicals, a complete work history will be obtained and would note any farm experience. These data may help clarify the reported association between brain cancer and farming.

Chronic fatigue syndrome (CFS) has been increasingly associated with immune dysregulation, including depressed natural killer cell activity; this phenomenon is associated with increased susceptibility to cancer. Although anecdotal reports have suggested an association between CFS and cancer, particularly non-Hodgkin's lymphoma and brain cancer, there has been no a priori justification for evaluating such an association and no consideration of relevant parameters, such as length of latent period vs. tumor type. We reviewed data from the Nevada State Cancer Registry subsequent to a reported outbreak of a CFS-like illness in Nevada that occurred during 1984-1986. We concentrated on non-Hodgkin's lymphoma and brain/CNS tumors, with particular emphasis on persons 15-34 and 35-54 years of age. An upward trend in the incidence of brain/CNS tumors, which could be related to a national upward trend for this disease, was noted. No consistent trends were noted for non-Hodgkin's lymphoma. Because of the difficulties inherent in studies of cancer subsequent to various exposures, we evaluated the methodology for determining an association between outbreaks of CFS-like disease and cancer. We propose several approaches that should be considered in future studies for investigation of possible associations between CFS and cancer, including expected latent periods for specific tumors.
