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.

The aim of this study was to investigate a possible relationship between occupational exposure to vehicle exhaust and cancer risk. For this purpose, a cohort of 14,225 truck drivers was followed throughout a ten-year period with regard to cause-specific mortality. Comparisons were made with another cohort of unskilled male laborers. Both of the occupational groups compared were identified at a census and no supplementary data on individual exposure history were available. The study showed an increased mortality for lung cancer (standardized mortality ratio (SMR) 160, 95% confidence interval (CI) 126-200) and multiple myeloma (SMR 439, 95% CI 142-1,024). It seems likely that exposure to diesel exhaust has contributed to the increased lung cancer risk observed. The possible relationship between multiple myeloma and certain constituents of vehicle exhaust may be worth attention in future investigations.

In a group of 10 patients (six with acute lymphatic leukaemia, one patient with Ewing's sarcoma, one patient with lung cancer, one patient with a myeloma and one patient with Hodgkin's lymphogranuloma) treatment with leucocytic growth factors (Neupogen Hoffman La Roche) was started only after the onset of leukopenia. Even after this mode of administration of leucocytic growth factors septic conditions in leukopenic patients were more easily controlled and it was thus possible to complete chemotherapy with planned doses in the planned time interval. In five patients with acute lymphatic leukaemia the leucocytic growth factors participated in the achievement of remission, in patients with myeloma and lymphogranuloma they contributed to marked improvement of the general condition and reduction of the time spent in hospital.

We assessed the survival after surgery in 153 patients with extremity metastases and 88 with spinal metastases. The survival rate for the whole series of 241 patients was 0.30 at 1 year, 0.15 at 2, and 0.08 at 3 years. The 1-year survival rate was the same for the extremity metastases group and the spinal group. Univariate analysis showed that 1-year survival was related to metastatic load, site of primary tumor, and presence of pathologic fracture. Multivariate regression analysis showed that pathologic fracture, visceral or brain metastases, and lung cancer were negative prognostic variables. Solitary skeletal metastases, breast and kidney cancer, myeloma, and lymphoma were positive variables. A prognostication model based on these variables stratified the patients into 3 groups with a 1-year survival ranging from 0.5 to 0.0. These prognostic variables can be used for differentiating the treatment of cancer patients with pathologic fracture or epidural compression.

Perhaps the best example of the integration of chemotherapy and biotherapy is autologous stem cell rescue following high dose chemotherapy. This analysis was undertaken to determine the outcome for patients treated in an autologous bone marrow transplant program, which was initiated in January 1989, and to illustrate the impact which biological response modifiers have had on the toxicity, survival, and costs associated with this aggressive treatment approach. Patients with metastatic cancer and good performance status were treated according to disease-specific treatment protocols. Peripheral blood stem cells [PBSC] came into use in 1990, hematopoietic colony stimulating factors [CSFs] in 1991. Outcome was monitored prospectively from the inception of the program. Five years after the program's inception, 75 patients had undergone 96 intensive chemotherapy treatments followed by autologous PBSC rescue. This included 35 patients with breast cancer, 15 with lymphoma or Hodgkin's Disease, five ovary, four melanoma, three sarcoma, three lung cancer, three leukemia, three testicular, two myeloma, one non-lung small cell carcinoma, and one medulloblastoma. Twenty-one patients underwent back-to-back cycles of intensive therapy and rescue; 14 of whom had breast cancer. Twelve patients were treated in 1989, 14 in 1990, 18 in 1991, 14 in 1992, and 17 in 1993. While four of the first 12 patients died within 60 days of reinfusion of cells in 1989, no patients have died within this time frame as a direct result of therapy during the subsequent four years. No patients have been lost to follow-up. Median survival was only eight months in 1989, but has not been reached for subsequent years. For all patients, median failure-free survival (FFS) is 17.2 months; 1-year FFS is 57%, 2-year 36%, and 3-year 29%. Median overall survival (OS) is 30.4 months; 1-year OS 66%, 2-year 52%, and 3-year 42%. From 1990-1993, for patients with metastatic breast cancer (21), and recurrent lymphoma (15), FFS and OS are comparable to the best results published from academic teaching hospitals. Twenty-one patients have survived over two years, 18 of whom continue in remission. Patients were hospitalized for an average of 31 days in 1989, 28.9 in 1990, 24.5 in 1991, and only 13.0-14.0 days in 1992-1993. Two patients were treated entirely as outpatients. Average hospital charges for the 96 treatments have been $120,000 with a range of $15,000 to $461,000, and currently average around $100,000.(ABSTRACT TRUNCATED AT 250 WORDS)

Mortality has been studied in 15,577 ankylosing spondylitis (AS) patients diagnosed between 1935 and 1957 in the UK, of whom 14,556 received X-ray treatment. By January 1, 1992 over half of the cohort had died. Among the irradiated patients, cancer mortality was significantly greater than expected from the national rates for England and Wales, with a ratio of observed deaths to expected (relative risk, RR) of 1.30, and significant increases individually for leukaemia, non-Hodgkin's lymphoma, multiple myeloma and cancers of the oesophagus, colon, pancreas, lung, bones, connective and soft tissue, prostate, bladder and kidney. Among the unirradiated patients, cancer mortality was lower than expected from national rates (RR = 0.79). Among irradiated patients, the RRs for leukaemia, lung cancer, and all other neoplasms all decreased significantly with increasing time since first treatment following an initial increase. By 35 years after first treatment, the radiation-related excess for lung cancer had completely disappeared, while for other neoplasms the RR remained significantly raised, although at a lower level than in earlier periods. Most irradiated patients received several courses of treatment within a 5-year period. Based on a 1 in 15 random sample, the mean total body dose received in this period was 2.64 Gy, with the heaviest dose to the vertebrae. A linear dose-response model for all neoplasms except leukaemia gave an excess RR of 0.18 Gy-1 in the period 5-24.9 years after first treatment, which decreased significantly to 0.11 Gy-1 in the period more than 25 years after first treatment. There was no evidence that a linear-quadratic model fitted the data better than a linear model. There were significant dose-response relationships individually for cancers of the lung, oesophagus, colon, pancreas, prostate, bladder and kidney.

We studied mortality among 8,878 employees who worked at any time from 1965 to 1988 at a synthetic fibers plant in North Carolina that used a finishing agent containing glycerol polyglycidyl ether. Some glycidyl ethers are mutagenic and tumorigenic in laboratory animals. The main route of exposure to workers was inhalation of the spray mist, although there was also skin contact. We identified 553 deaths in the cohort and the standardized mortality ratio (SMR) from all causes of death combined was 0.80. For most causes of death, mortality rates in the cohort were similar to mortality rates in the U.S. population. Among categories with at least five observed deaths, the largest effect estimate was for cancer of the central nervous system (SMR = 1.77), and the SMR for lung cancer was 0.94. The cancer categories of central nervous system (brain) and "other" lymphopoietic cancers (lymphoma and myeloma) showed weak associations with duration of employment. In case-control analyses in which we utilized work history data to compute effect estimates by duration of exposure, we found no increased risk of lung cancer or brain cancer among employees with more than 5 years of exposure. Effect estimates for lymphoma and myeloma tended to increase with duration of exposure, although there were only seven deaths in this category and the effect estimates were very imprecise. To date, this study has identified no clear carcinogenic effect of glycerol polyglycidyl ether, but plausible induction periods have not yet elapsed. The cohort should continue to be monitored to obtain more precise estimates after moderate or long induction times.

Mortality data have been updated for a further 12 years for a cohort of workers in the reinforced plastics and composites industry with exposures to styrene monomer and other chemicals. The cohort consisted of 15,826 male and female employees who were exposed to styrene for at least six months between 1948 and 1977 at 30 participating manufacturing plants in the United States. A total of 1628 deaths were reported during the extended observation period, 1948-89. Mortality from several causes showed significant increases--namely, all causes, all cancers, oesophageal cancer, lung cancer, cancer of the cervix uteri, cancer of other female genital organs, hypertensive heart disease, certain non-malignant respiratory diseases, motor vehicle accidents, and homicides. When, however, mortality data were examined in terms of duration of employment, durations of styrene exposure, and cumulative styrene exposure no upward trend was detected in any of these causes of death. Most of the increases in mortality were among workers who were employed for only six months to a year or who had very low cumulative exposure (< 10 ppm-years). Therefore, the increased mortality was not likely to be related to exposure to styrene. Several explanations for the increased mortality are offered, including low socioeconomic class, smoking, and lifestyle factors characteristic of short term workers. There was no increased mortality from lymphatic and haematopoietic cancers overall or from any specific haematological malignancies. In particular, no increase in mortality from non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, or leukaemia was found. Furthermore, detailed exposure-response analyses did not show any relation between exposure to styrene and any of these haematological malignancies. The lack of an exposure-response relation further supports the conclusion that workers in the reinforced plastics industry in this study did not experience any increased risk of lymphatic and haematopoietic cancers as a result of their exposure to styrene.

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.

The risk of cancer was evaluated among 77,952 asthma patients with bronchial asthma. The series was obtained through linkage of two registers: the Finnish Social Insurance Institution's file of asthma patients and the Finnish Cancer Registry. There was a significant excess risk of lung cancer in both sexes, the standardized incidence ratio (SIR) being 1.32 among men and 1.66 among women. In women, the risk of cancer of the rectum was significantly increased (SIR 1.42), whereas the risks of cancer of the corpus uteri and multiple myeloma were lower than expected (SIR 0.76 and 0.53, respectively). In men, the incidence of cancer of the larynx was significantly reduced (SIR 0.63) and that of the bladder increased (SIR 1.25). When both sexes were combined, cancers of the colon (SIR 1.17) and rectum (SIR 1.28) also showed a significantly elevated risk. A reduction in risk was seen in stomach cancer (SIR 0.88) and lymphatic leukaemia (SIR 0.55). The increased lung cancer risk may be due to local inflammatory changes. It is possible that differences in the immune system, e.g. natural killer cell activity, explain some of the reduced cancer risks.
