A total of 69 bladder cancer, 76 lung cancer and 59 liver cancer deceased cases and 368 alive community controls group-matched on age and sex were studied to evaluate the association between high-arsenic artesian well water and cancers in the endemic area of blackfoot disease (BFD), a unique peripheral vascular disease related to continuous arsenic exposure. According to a standardized structured questionnaire, information on risk factors was obtained through proxy interview of the cases and personal interview of the controls. A positive dose-response relationship was observed between the exposure to artesian well water and cancers of bladder, lung and liver. The age-sex-adjusted odds ratios of developing bladder, lung and liver cancers for those who had used artesian well water for 40 or more years were 3.90, 3.39, and 2.67, respectively, as compared with those who never used artesian well water. Multiple binary logistic regression analyses showed that the dose-response relationships and odds ratios remained much the same while other risk factors were further adjusted.

Age-adjusted mortality rates (MRs) in all four population groups in the RSA (age range 25 - 74 years) for different types of cancer were compared and ranked. Lung and stomach cancer had the highest MRs in white, Indian and coloured males. In white males lung cancer ranked 1st (MR more than twice as high as that for stomach cancer), while in Indian and coloured males stomach cancer ranked 1st and lung cancer 2nd. The MR for lung cancer in coloured males was a little higher than that in white males. In black males oesophageal cancer ranked 1st and liver cancer 2nd. In white females breast cancer ranked 1st and lung cancer 2nd. In coloured females cancer of the cervix ranked 1st followed by cancer of the breast and of the stomach. In black females cancer of the oesophagus and of the liver ranked 2nd and 3rd after cancer of the cervix, and in Indian females the rank order was stomach cancer 1st, breast cancer 2nd, and cervical cancer 3rd. Cancers of the rectum and bladder were low in the rank order in both males and females of all four population groups. The main feature of age-specific MRs for the more common cancers was the fact that MRs for stomach cancer in both coloured males and females were relatively high in the younger age groups. Also, the MRs for cancer of the cervix in coloured and black females were not only higher at all ages (except in the highest age group in blacks) but were particularly high in the younger age groups compared with figures for the other populations.

Extensive follow-up of production workers in the paint and coatings industry failed to indicate any important hazard that was previously unsuspected. The authors are more confident of the results of their original study since studying a subsample of persons lost to follow-up in the original study. Some efforts to investigate certain diseases (skin and liver cancer) more vigorously met with failure, which illustrates the problem of attempting retrospective studies by using death certificates for case ascertainment. Of the successful studies, the leukemia case-control analysis showed a possible relationship to lacquer production, which probably included benzene exposure. For lung cancer, no exposure category was associated with increased risk. The bowel cancer excesses, concentrated in three plants, are probably not job related and in any case do not represent an industry-wide problem. Cerebrovascular accidents showed a mild elevation of risk for vehicle workers. Although strong statements concerning the safety of this industry probably await more studies or further follow-up of this cohort, there is every indication that it is an industry without a major excess of any job-related disease. In drawing this conclusion, however, one must be aware that an individual job or individual plant could harbor health problems that would not be detected by a study of this type.

A 10% increased risk of developing a second cancer was observed among approximately 36,000 persons reported to the Danish Cancer Registry with a cancer of the respiratory system during 1943-80. This estimate is markedly influenced by a striking tendency by physicians not to report or the Cancer Registry not to accept a report of a second lung cancer following a primary lung cancer (14 observed vs. 99 expected). A significant 30% excess of all second cancer was seen after laryngeal cancer (368 vs. 282), whereas the 22% excess following cancer of the nasal cavities and paranasal sinuses did not quite reach the level of statistical significance (95% CI = 0.9-1.6). For cancers of the lung and larynx, second cancers arose mainly in the buccal cavity, bladder, kidney (after lung cancer only) and lung (after laryngeal cancer only). These second cancers may be due to common carcinogenic factors, most likely tobacco. Elevated risks of second cancers of the breast, cervix uteri, and other female genital organs were found consistently. Radiotherapy may have contributed to the increased risk of breast cancer, but the excess risk of cancer of the female genital organs other than the cervix was unexpected. Although not significant, the risk of esophageal cancer following cancer of the larynx was below expectation (1 vs. 4.1), which was surprising because alcohol consumption and smoking are thought to be common risk factors for these 2 sites. Significant excesses of pancreatic cancer were observed following cancers of the lung, larynx, and nasal cavities, which might be due to more careful medical surveillance of these patients or to common risk factors such as cigarette smoking. Finally, the risk of a patient developing liver cancer after lung cancer was significantly elevated (22 vs. 11.6). This increase is unlikely to be due to misdiagnosed metastases from the lung, inasmuch as the risk was generally elevated throughout the observation period.

Selective deposition of lipiodol in primary and metastatic liver cancer, lung cancer, gallbladder cancer, pancreatic cancer and renal cancer was elucidated by plain X-ray film and CT. Selective delivery of anticancer agent, SMANCS was also proved by measurement of its biological activities of removed specimen. Because of these selective delivery of anticancer agent and embolization of neovasculature in the tumor, highly effective chemotherapy of unresectable cancer was established. Drug was given via celiac, the hepatic, bronchial or renal artery mostly 1-5 mg in 1-5 ml of lipiodol once every 3-8 weeks. Antitumor effects of this therapy for hepatocellular carcinoma was confirmed based on decrease in AFP levels (92% of the cases), reduction in tumor size (90% of the cases) and histology. In 76 percent of the patients with the other malignant solid tumors reduction in tumor size was recognized. Decrease in CEA level occurred in 88 percent of the cases with metastatic liver cancer and lung cancer. Major side effect was transient fever in about 50% of cases. Mitomycin C and aclarubicin dissolved in lipiodol showed remarkable antitumor effects for experimental liver cancer.

Primary liver cancer incidence data from 30 populations reported in Cancer Incidence in Five Continents were analyzed. After adjustment for time trends, log incidence increases linearly with log age. Liver cancer risk increases more rapidly with age than that of colon cancer, stomach cancer, or lung cancer in non-smokers; it increases less rapidly than that of prostatic cancer or of lung cancer in smokers. Over the past 20 years, most populations have been found to have increasing age-adjusted liver cancer incidence. There is no correlation between change in rates and magnitude of rates. Male rates are higher than female rates and the ratio of the two tends to be higher in high-risk areas.

The author indicates briefly the results from the statistical and epidemiological studies of cancer in Spain. Between 1903 and 1978 cancer mortality passed from 39.00 per 100.000 to 152.4 per 100.000, and sex distribution from 43% men and 56% women to 57% men and 42% women. Cancer represented 1.52% of the total mortality in 1903 and 18.95% in 1978. The largest incidence of cancer diseases is observed for ages between 45 and 75 years in men, with a maximum at 60, and between 40 and 71 years in women, with a maximum at 55. In all Spanish regions the most frequent mortal localizations are lung cancer among men and mammary cancer among women. The second place corresponds to stomach cancer in both sexes. Other important causes of death are the tumors of the prostate, liver, urinary bladder, larynx, colon and rectum, hematopoietic system, and esophagus in man, and the neoplasms of liver, lung, body of the uterus, colon and rectum, hematopoietic system and gallbladder and bile ducts in women. It is surprising the high frequency of primitive liver cancer in some regions, reaching an incidence of 4.39% in Tarragona and 6.07% in Zaragoza.

A cohort of 13,114 workers employed during 1930-1975 in two Swedish plants producing tires and industrial rubber goods was investigated with regard to cancer mortality and cancer incidence. Separate analyses were performed on the following subgroups of the cohort: mixers/weighers, other production workers, and white-collar employees. For all causes of death no increase of risk was observed in the population as a whole. Mixers/weighers showed however an increased overall standardized mortality ratio. The pattern of causes of death was not changed in the total cohort. An increased risk to die from liver cancer (risk ratio 4.12) and pancreatic cancer (risk ratio 2.70) was, however, observed for the category other production workers. An increased risk of death from tumors of the respiratory organs was also observed for the categories other production workers (risk ratio 1.89) and white-collar employees (risk ratio 2.63). For tumors in the urinary bladder (risk ratio 2.50) and for ischemic heart diseases (risk ratio 1.27) the death risk was elevated for the category other production workers. The cancer morbidity pattern showed an increase in malignant melanomas (risk ratio 2.50) for the category other production workers and for lung cancer (risk ratio 2.09), as well as for tumors in the nervous system (risk ratio 3.18) for white-collar employees.

Overall, the results of the analysis of 12 studies of VC production and polymerization workers demonstrate an enormously elevated risk of liver malignancies, the possibility of a twofold increased risk of brain and central nervous system tumors and perhaps, also, of malignancies of the lymphatic and hematopoietic system. However, the role of other agents cannot be excluded in the etiology of nonhepatic malignancies. Bronchogenic carcinoma does not appear to be increased from exposures to VC monomer, although a relationship to PVC dust was suggested in one study. These conclusions must be considered in light of limited data on workers followed more than 25 years from onset of exposure. Considering the numbers of observed and expected deaths in all studies, it would appear that the excess of malignancies at nonhepatic sites is less than the excess of liver tumors. Data presented elsewhere in this volume (Nicholson and Henneberger, 1983) suggest that exposure reductions in 1974 may have virtually eliminated the VC-associated risk of liver cancer if the current U.S. standard is met. To the extent that VC exposure is associated with other cancers, a similar risk reduction would be expected. Raynaud's phenomenon, acroosteolysis, scleroderma-like skin lesions, hepato- and splenomegaly with noncirrhotic hepatic fibrosis, and severe portal hypertension have been associated with past heavy exposures to VC. Evidence exists that the liver disease and portal hypertension may progress following cessation of exposure. However, all of the above syndromes were found largely in heavily exposed individuals. Their occurrence would be much less likely in workers exposed only to concentrations currently allowed. Pulmonary deficits, X-ray abnormalities, and, perhaps, lung cancer have been associated with VC/PVC exposure. Because of the possible contribution of PVC dust to these findings, engineering controls during polymer drying, bagging and usage are warranted.

The concentrations of N-terminal peptide of type III procollagen in the sera of patients with various cancers were measured by radioimmunoassay. The mean value (with standard deviation) in the control group was 9.9 +/- 2.6 ng/ml. Serum levels exceeding 15 ng/ml were defined as positive, and it was found that 94% of 18 patients with primary liver cancer with cirrhosis, 88% of 8 patients with primary liver cancer without cirrhosis, 77% of 13 patients with metastatic liver cancer, 86% of 7 patients with recurrent breast cancer, 86% of 8 patients with colonic cancer, 75% of 8 patients with pancreatic cancer, 70% of 23 patients with stomach cancer, 51% of 35 patients with lung cancer, and 54% of 28 patients with uterine cancer showed positive levels. The concentrations showed great intersubject variations, probably reflecting the activity of tumor growth and/or invasion. The concentrations in the sera of patients with primary liver cancer with cirrhosis were generally higher than those in patients with liver cirrhosis alone or primary liver cancer without cirrhosis. This result suggested that the growth of primary liver cancer complicated by cirrhosis might be detected by serial measurements of this peptide in the serum of patients with liver cirrhosis. Present data suggested that this peptide is not cancer-specific, but assay of the peptide might be of value as an auxiliary means of detecting and monitoring various cancers, especially liver cancer.
