The patterns of cancer risk by religion in the large multidenominational population of Los Angeles County were examined with the method of proportional incidence. Risk estimates for individual cancers by religion were screened and those extreme but stable estimates found were reexamined in light of relative socioeconomic class, nativity, and ethnicity. Within Protestant denominations, gradients which can still best be attributed to religious preference were observed for leukemia, stomach, and cervix cancer. Roman Catholics tend to have high risks of stomach and gallbladder and a low risk of prostate cancer, whereas Eastern Orthodox women trade high risk of stomach cancer for low risk of endometrial and lung cancer. The most extreme pattern of risk, that for Jews, is comprised of lowered risk for cervical cancer and for most sites usually associated with smoking, plus consistently higher risk for lymphomas, thyroid cancer, and bladder cancer among males. Like Jews, Seventh-Day Adventists experience high risk for lymphoma and low risk for cervical and respiratory cancers. Risk to Mormons in Los Angeles differs from that of the standard Protestant population in only minor and inconsistent ways. Neither Mormons nor Adventists showed the previously reported deficits of colorectal or breast cancer. Although the method of proportional incidence may be partly responsible for our failure to confirm previous findings, nonreligious cultural or methodologic factors in the original investigations also provide plausible explanations. More generally, associations of the modest magnitude observed between cancer risk and religion in American populations should probably not be attributed to religious life-style, unless extraordinary circumstances permit the exclusion of other determinants.

Two-hundred and fifty-eight patients treated with high-activity 131I for thyroid cancer and on prolonged follow-up have been reviewed to determine long-term hazards and their relation to the radiation dose received. The expectation of life of those dying from causes other than cancer was slightly reduced in the female patients. A small, significant excess of deaths from cancer of the bladder and from leukaemia was found which, assuming that these were due to radiation, gave inferred risk-rates respectively of 0.4 and 4.9 deaths per 10(4) PYG (patient-year-grays) to the bladder wall and red marrow. Of 31 younger patients (eight male, 23 female), four of the marriages have been infertile. The fertile marriages produced a total of 44 live births. Considerable gonad irradiation (estimated 0.8-2.7 Gy) was compatible with apparently normal fertility. Despite the high level of irradiation of the salivary glands, no malignancies and only one adenoma was found. Impaired pulmonary function occurred in only one of the patients who had diffuse bilateral metastases. In this patient, tumour in the lung was persistent throughout, so that radiation was probably not alone responsible.

A cohort study was conducted of the membership of a large international union of painters and allied tradesmen. The union membership consisted of both painters and associated trades such as glaziers and tile and carpet layers. The study examined the mortality experience of 57 175 current and former union members in four states (California, Missouri, New York, and Texas) in the United States (US) from 1975 through 1979. No excess mortality was observed for the total union membership when compared to that of all US white males. When the study population was subdivided by the trade affiliation, members of locals comprised primarily of painters exhibited a significant elevation in mortality from all malignant neoplasms, lung cancer, and stomach cancer, compared to all US white males. To reduce the impact of potential nonoccupational differences between the study population and all US white males, the data were also analyzed using the entire cohort as the standardization population. Significant elevations continued to be observed for all malignant neoplasms and lung cancer among the membership of painting locals compared to other locals. In addition there was a statistically significant difference in mortality from leukemia and cancer of the bladder observed between the groups.

An association between bladder cancer and employment as an artistic painter was found in two study populations. A proportionate mortality analysis of death certificates of professional artists indicated a greater than twofold excess for bladder cancer mortality among painters. This association was further investigated in a large case-control interview study of bladder cancer patients where an overall relative risk estimate of 2.5 was found among artistic painters. Excess deaths from leukemia and arteriosclerotic heart disease also occurred in the proportionate mortality study. Information was not available to determine exposure to specific substances that may have been responsible for these observations; however, efforts should be made to limit exposure to art materials known to be hazardous.

Workers in the corn wet-milling industry are exposed to grain dusts, pesticides and fumigants, acids, solvents, sulphur dioxide, and other chemicals used in the manufacture of starch, oil, syrup, and dextrins. In a preliminary investigation of the long-term health effects of occupational exposures in this industry, deaths among active and retired corn wet-milling workers were identified from records of a trade union. Underlying cause of death for workers who died between 1947 and 1981 was determined from death certificates. Cause-specific Proportionate Mortality Ratios (PMR's) were computed for white and black males using US males as a comparison with adjustments for age, race, and calendar year of death. There were deficits of deaths from respiratory and digestive diseases. Among whites, mortality from chronic nephritis, bladder cancer, and lymphatic and haematopoietic malignancies was elevated. There was an elevated frequency of deaths due to diabetes and a threefold excess of pancreatic cancer deaths among blacks. Crude work history information indicated a small cluster of pancreatic cancer deaths among whites and blacks who had worked in production processes that convert corn starch to syrup and dextrins. An elevated frequency of deaths from leukaemia was seen among white maintenance workers.

Causes of death among 1598 professional artists were compared with an expected distribution based on the general U.S. population to determine if there were unusual patterns of fatal disease that might be indicative of exposure to hazardous substances in their work environment. Deaths among men and women in the arts were identified from obituaries in Who's Who in American Art published between 1940 and 1969. Among 1253 white male artists, PMRs were significantly elevated for arteriosclerotic heart disease, leukemia and cancers of the bladder, colon, rectum, kidney, and brain. The significant excesses of bladder cancer and leukemia deaths were limited to painters. Proportions of deaths due to colon cancer were significantly elevated among male painters and sculptors. Prostate cancer mortality was slightly higher than expected among painters and significantly elevated among sculptors. Among 345 female artists, painters represented the only specialty category large enough to analyze and excess numbers of deaths due to cancers of the rectum, lung, and breast were noted.

The risk of a second primary cancer developing was evaluated in nearly 20,000 men with cancers of the prostate or testis in Connecticut, 1935-82. Among 18,135 men with prostate cancer, a significant 15% deficit of all second cancers was observed [1,053 vs. 1,241; relative risk (RR) = 0.85; 95% CI = 0.80-0.90], most notably for respiratory (RR = 0.7) and digestive cancers (RR = 0.8). The absence of a colon cancer risk lends little support to the idea of common risk factors such as dietary fat consumption. Only the risk for salivary gland cancer was significantly increased, possibly due to chance. Leukemia was significantly elevated among men observed for 10 and more years (RR = 2.2). In contrast to most other index tumors, the prostate stands out as being associated with an overall low risk of second cancer development. The reasons for these deficiencies have not been explained. Among 1,446 men with testis cancer, a significant twofold risk of second cancers was seen (104 vs. 50.1). A fivefold risk of leukemia (8 vs. 1.5) was not related to treatment or age. Contralateral testis cancer (6 vs. 0.5) was elevated in men treated with and without radiation. Risks for kidney cancer (5 vs. 1.5), bladder cancer (9 vs. 3.4), pancreatic cancer (6 vs. 1.5), non-Hodgkin's lymphoma (6 vs. 1.5), and prostate cancer (12 vs. 5.9) were significantly increased. No trends over time were noted for any cancer. Overall risk of second cancer development tended to be higher in younger men with testis cancer. The relationship of leukemia to testis and prostate cancers should be investigated in future research.

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)

In Denmark, approximately 5% of all malignant neoplasms occur within the lymphatic and hematopoietic tissues. Between 1943 and 1980, 23,367 persons with these diseases fulfilled the criteria for entering the study. The risk of developing a second primary cancer was significantly increased only after Hodgkin's disease [relative risk (RR) = 1.6], whereas no increase was found after non-Hodgkin's lymphoma [(NHL); RR = 1.0] or leukemia (RR = 1.1), and a significant deficit occurred after multiple myeloma (RR = 0.8). All initial cancer sites showed a higher incidence of second primary cancers among males than females. Significant elevated risks for acute non-lymphocytic leukemia occurred after Hodgkin's disease (RR = 17), NHL (3.8), and multiple myeloma (9.1). Among persons initially diagnosed with leukemia, NHL was significantly elevated (RR = 2.6). However, these RR should be regarded as minimum figures due to the likelihood of serious underreporting of second primary hematologic cancers in Denmark. The secondary leukemias were likely induced by the treatment of the first primary cancer (chemotherapy, radiotherapy), but common etiologies, misclassification, or progression of the initial cancer cannot be ruled out entirely. Other second primary cancers found to be above expectation following Hodgkin's disease were cancers of the pancreas, lung, and urinary bladder. The risk for bladder cancer increased with time, which suggested a causal relation to radiation or chemotherapy, or both. Cancers of the colon and rectum following NHL and female breast cancer following leukemia occurred below expectation and remain unexplained.

Comparison between the age-adjusted death rates in 1964-65 from cancers of different sites and the annual consumption of cigarettes, solid fuel, tea and coffee as measured by trade statistics in 20 countries reveals the existence of significant correlations.Cigarette consumption per adult in the population is positively related with lung and bladder cancer in males and insignificantly with lung in females. Negative relations are indicated with the liver and biliary passages, prostate and uterus.Solid fuel is positively related with the intestine, lung and bladder in both sexes, with leukaemia in males and with breast in females. Nagative associations are indicated with the stomach.Tea is positively related with intestine except rectum in both sexes and with larynx, lung and breast in females. Negative associations are indicated with the stomach in both sexes and with uterus and leukaemia in females.Coffee is positively related with the pancreas, prostate and leukaemia in males and with ovary and leukaemia in females.Specially noteworthy were the contrasts between the intestine and stomach in their associations with solid fuel, cigarettes and tea for which a possible explanation has been suggested.
