This report describes mortality occurring between 1940 and mid-1978 among 29,087 men and women employed in a rubber plant for at least two years. Mortality patterns for the period July 1, 1974, to July 1, 1978, were compared to previously published findings for January 1, 1940, through June 30, 1974. Expected numbers of deaths were based on U.S. general population mortality data. There were excess deaths from bladder cancer and leukemia among white male union members during both follow-up periods. During recent follow-up of white male union members employed for at least five years, there were excesses in deaths from three additional cancers: esophageal cancer (11 observed/4.8 expected), biliary and liver cancer (6 observed/3.3 expected) and lymphoma and multiple myeloma (14 observed/5.8 expected). Evidence from other studies of rubber workers suggests that observed excesses in deaths from bladder cancer and leukemia are related to work-place exposures. The present findings suggest that occupational exposures etiologically relevant to these diseases may not have been reduced in recent years or that sufficient time has not elapsed for such reductions to result in decreased mortality. Further investigation is required to clarify the contribution of occupational factors to observed excesses in deaths form cancers of the esophagus and the biliary passages and liver and from lymphoma and multiple myeloma.

Risk of cancer mortality from 1973 to 1985 in persons born in the Indian subcontinent who migrated to England and Wales was analysed by ethnicity, and compared with cancer mortality in the England and Wales native population, using data from England and Wales death certificates. There were substantial highly significant raised risks in Indian ethnic migrants for cancers of the mouth and pharynx, gall bladder, and liver in each sex, larynx and thyroid in males, and oesophagus in females. There were also substantial raised risks in these migrants of each sex for non-Hodgkin's lymphoma and myeloma. For the mouth and pharynx, and liver in each sex, and gall bladder in females, there were also raised risks of lesser magnitude in British ethnic migrants. For colon and rectal cancer and cutaneous melanoma in each sex, ovarian cancer in women and bladder cancer in men, there were appreciable significantly reduced risks in the Indian ethnic migrants not shared by those of British ethnicity. Appreciable raised risks in British ethnic migrants not shared by those of Indian ethnicity occurred for nasopharyngeal cancer in males, soft tissue malignancy in both sexes and non-melanoma skin cancer in males. In migrants of both ethnicities there were appreciable significantly raised risks in each sex for leukaemia and decreased risks in each sex for gastric cancer, for lung cancer except in females of British ethnicity and in males for testicular cancer. The results suggest the need for public health measures to combat the high risks of oral and pharyngeal cancers and liver cancer in the Indian ethnic immigrant population of England and Wales, by prevention of betel quid chewing and hepatitis transmission respectively. The data also imply that early exposures or early acquired behaviours in India, or exposures during migration, may increase the risk of leukaemia and reduce the risks of gastric and testicular cancers in the migrants irrespective of their ethnicity. Aetiological studies would be worthwhile to investigate the reasons for the sizeable decreased risk of colon and rectal cancer and increased risk of gall bladder cancer in each sex and the increased risk of thyroid and laryngeal cancer in males and oesophageal cancer in females of Indian ethnicity but not of British ethnicity who have migrated from the Indian subcontinent.

Recent observations have suggested that radon in the ambient air may cause cancers at sites other than the lung, but the evidence is indirect. We have studied site-specific cancer mortality in 4320 uranium miners in West Bohemia who have been followed-up for an average of 25 years, and in whom a four-fold radon-related excess of lung cancer has already been established. For all cancers other than lung cancer the number of deaths observed was slightly greater than that expected from national rates, but the increase was not significant statistically (ratio of observed to expected deaths [O/E] = 1.11, 95% confidence interval [CI] = 0.98-1.24) and mortality did not increase with duration of employment underground or with cumulative exposure to radon. Non-lung cancer mortality was significantly raised among men who started mining work aged under 25 but the increase was not related to cumulative radon exposure. When twenty-eight individual sites and types of cancer were examined, significantly increased risks were found for cancers of the liver (O/E = 1.67) and gallbladder and extrahepatic bile ducts (O/E = 2.26). For liver cancer, mortality did not increase with duration of employment underground or with cumulative radon exposure. For cancer of the gallbladder and extrahepatic bile ducts, mortality did not increase with duration of employment, but increased with cumulative exposure to radon. Mortality from multiple myeloma, although not significantly increased overall (O/E = 1.08), increased with cumulative exposure to radon. Mortality from leukaemia was not increased overall (O/E = 0.91) and was not related to cumulative radon exposure, but did increase with increasing duration of employment in the mines. There is no evidence in these miners that a radon-rich atmosphere increases the risk of any cancer other than lung cancer. Possible exceptions are cancer of the gallbladder and extrahepatic bile ducts and multiple myeloma but further study is needed before it can be concluded that the associations found are causal.

Occupation and industry codes on death certificates from 23 states for 1984-1988 were used to evaluate mortality risks among white and nonwhite, male and female farmers. Proportionate mortality and proportionate cancer mortality ratios were calculated using deaths among nonfarmers from the same states to generate expected numbers. Among farmers there were 119,648 deaths among white men, 2,400 among white women, 11,446 among nonwhite men, and 2,066 among nonwhite women. Deficits occurred in all race-sex groups for infective and parasitic diseases, all cancer combined, lung cancer, liver cancer, diseases of the nervous system, multiple sclerosis, hypertension, and emphysema. As reported in other studies, white male farmers had excesses of cancer of the lymphatic and hematopoietic system, lip, eye, brain, and prostate. Excesses of cancers of the pancreas, kidney, bone, and thyroid were new findings. Regional patterns were evident, particularly among white men. Significant excesses for accidents, vascular lesions of the central nervous system (CNS), and cancers of the prostate tended to occur in most geographic regions, while excesses for mechanical suffocation, non-Hodgkin's lymphoma, and cancers of the lip, brain, and the lymphatic and hematopoietic system were limited to the Central states. Increases among nonwhite men were similar to those in white men for some causes of death (vascular lesions of the CNS and cancers of the pancreas and prostate), but were absent for others (lymphatic and hematopoietic system, lip, eye, kidney, and brain). Women (white and nonwhite) had excesses for vascular lesions of the CNS, disease of the genitourinary system (white women only), and cancers of the stomach and cervix (nonwhite women only). Cancer of the buccal cavity and pharynx was slightly elevated among women, and white women had nonsignificant excesses of multiple myeloma and leukemia. Excesses for leukemia and non-Hodgkin's lymphoma occurred among white men and women, but not among nonwhites. Excesses for several types of accidental deaths were seen among all race-sex groups.

Longer and better survival of End-Stage Renal Disease (ESRD) patients undergoing renal replacement therapy (RRT) is now associated with a higher prevalence of new elderly patients receiving renal replacement therapy (dialysis). In order to help clarify the association of cancer risk with RRT, the incidence of cancer in a population-based cohort of uraemic patients in the Region of Lombardy, northern Italy, was undertaken using data from the Lombardy Regional Dialysis and Renal Transplant Registry. A total of 479 cases of cancer of all sites was recorded in this population. There were statistically significantly elevated risks of primary liver cancer, kidney cancer, thyroid cancer, lymphoma and multiple myeloma. When the data were examined according to primary renal diseases, there did not appear to be any particular association between excess cancer risk and the underlying pathology. While some caution must be expressed in interpreting these data, due to the relatively small numbers of cases expected in many of the disease entities, the results indicate an excess of renal-cell and liver carcinomas and lymphomas in patients receiving RRT and highlight the necessity of careful follow-up and awareness of these associations, together with the need for early detection of such tumours.

Using data from a case-control study in the United States (the Selected Cancers Study), we examined the relationship between non-Hodgkin's lymphoma (NHL) and family history of different cancers. Cases were 1,511 men aged 31 to 59 years and diagnosed pathologically with non-Hodgkin's lymphoma during 1984-88. Controls were men, frequency-matched to cases by age range and cancer registry (n = 1,910). All study subjects with acquired immunodeficiency syndrome were excluded from analyses. Our results showed that the risk of NHL is associated with a history of lymphoma (odds ratio [OR] = 3.0, 95 percent confidence interval [CI] = 1.7-5.2) and hematologic cancer (OR = 2.0, CI = 1.2-3.4) in first-degree relatives after adjustment for age, ethnic background, and educational level. Further analyses were performed for the subgroups defined by age at diagnosis (younger than 45 years cf 45 years or older). The association of NHL with a family history of lymphoma and hematologic cancer was found primarily among men aged 45 and older (OR = 4.1, CI = 1.9-8.8 for lymphoma and OR = 2.3, CI = 1.3-4.0 for hematologic cancer). The association among men aged 45 and older did not vary by whether or not there were any familial patients diagnosed at the age of 45 or older. No significant associations could be found for a family history of lung cancer, breast cancer, prostate cancer, colon cancer, skin cancer, liver cancer, stomach cancer, brain cancer, thyroid cancer, or myeloma. This study suggests that the familial risk of NHL is influenced primarily by hematolymphoproliferative malignancies rather than other cancers. The familial effects of hematolymphoproliferative malignancies may be stronger for men aged 45 to 59, compared with those aged 31 to 44.

Six patients with multiple myeloma (MM) and a second non-hematological neoplasm (solid tumor) are documented in this study. Two patients had a previous history of adenocarcinoma of the colon prior to MM diagnosis; in three patients a second neoplasm (lung cancer, adenocarcinoma of the urinary bladder and adenocarcinoma of the colon) appeared at the time of MM diagnosis; one patient, a woman with a six-year history of MM, developed hepatoma. The two patients who had had a neoplasm of the colon ten years before and the patient with bladder carcinoma, responded to MM therapy. The patient with lung cancer and the patient with adenocarcinoma of the colon died; the last patient, with MM and liver cancer, is alive but with aggressive disease. In conclusion we have found that in MM patients a second neoplasm may develop or co-exist, in greater frequency than that of the general population.

Analysis of familial cancer risks between discordant sites provides etiologic understanding on genetic and environmental risks factors of site-specific cancers. We used the Swedish nation-wide Family-Cancer Database to analyze familial risks in discordant cancers of offspring and parents. Familial risk ratios (FRRs) were calculated for cancer in offspring aged 15 to 53 years at 22 sites, discordant from parental sites. We confirmed many reported associations. Consistent novel findings associated parental-offspring sites of pancreas-breast, breast-testis and uterus-nervous system. For these, the FRRs were modest, 1.2 to 1.5 in the whole Database, but the FRRs increased in those whose parents were diagnosed before age 50. Pancreas and liver cancers showed FRRs of 2.5 to 3.3 in offspring of women and of 1.3 in offspring of men. One or both of these cancers was/were associated with cancers of stomach, colon, breast, uterus, ovary and prostate. Melanoma was associated with pancreas, breast, skin and nervous-system cancers and with leukemias. Myeloma showed a concordant FRR of about 4.0 and was associated with prostate cancer and non-thyroid endocrine-gland cancers. Mutations in known cancer-related genes may explain some of these findings, but new susceptibility genes are yet to be found. For melanoma, pancreatic and liver cancer, environmental factors are important etiologic factors and may contribute to the familial effects observed.

To explore the role of DDE, the major and most persistent DDT derivative, in cancer etiology, we examined the association of the 1968 adipose DDE levels of population samples from 22 U.S. states with age-adjusted mortality rates between 1975 and 1994 for multiple myeloma; non-Hodgkin lymphoma (NHL); and cancer of the breast, corpus uteri, liver, and pancreas. Separate analyses were conducted by gender and race. Covariates in the regression models included average per-capita income, percent metropolitan residents, and the population density. Liver cancer mortality increased significantly with adipose DDE levels in both sexes among whites, but not among African Americans. No association was observed for pancreatic cancer and multiple myeloma. Breast cancer mortality was inversely correlated with adipose DDE levels among both white and African American women. Significant inverse correlations were also observed for uterine cancer among white women, whereas no association was observed for African Americans and for NHL among whites (men and women) and African American women. The results for pancreatic cancer, multiple myeloma, NHL, breast cancer, and uterine cancer did not support the hypothesis of an association with past adipose levels of the DDT derivative DDE. The multivariate analysis confirmed most findings. The association between liver cancer and DDE observed among whites, particularly in view of the occurrence of hepatic neoplasms in laboratory animals exposed to DDT, warrants further investigation.

Trichloroethylene is an organic chemical that has been used in dry cleaning, for metal degreasing, and as a solvent for oils and resins. It has been shown to cause liver and kidney cancer in experimental animals. This article reviews over 80 published papers and letters on the cancer epidemiology of people exposed to trichloroethylene. Evidence of excess cancer incidence among occupational cohorts with the most rigorous exposure assessment is found for kidney cancer (relative risk [RR] = 1.7, 95% confidence interval [CI] 1.1-2.7), liver cancer (RR = 1.9, 95% CI(1.0-3.4), and non-Hodgkin's lymphoma (RR = 1.5, 95% CI 0.9-2.3) as well as for cervical cancer, Hodgkin's disease, and multiple myeloma. However, since few studies isolate trichloroethylene exposure, results are likely confounded by exposure to other solvents and other risk factors. Although we believe that solvent exposure causes cancer in humans and that trichloroethylene likely is one of the active agents, we recommend further study to better specify the specific agents that confer this risk and to estimate the magnitude of that risk.
