There is accumulating evidence that free radicals may contribute to various diseases such as cancer or cardiovascular disease. Possible health hazards can to some extent be prevented by the body's multilevel defense system against free radicals, which comprises, besides others, antioxidant vitamins. The 12-year mortality follow-up of 2,974 participants of the Basal Study allowed to test the hypothesis that low antioxidant vitamin plasma concentrations (vitamin A, C, E and carotene) were associated with increased death from cancer of various sites and death from atherosclerosis such as ischemic heart disease and stroke, respectively. For the analysis 204 cancer cases, 132 fatalities from ischemic heart disease (IHD) and 31 deaths from cerebral vascular disease were available. Cancer mortality. Overall mortality from cancer was associated with low mean plasma levels of carotene adjusted for cholesterol (p less than 0.01) and of vitamin C (p less than 0.01). Bronchus and stomach cancers were associated with a low mean plasma carotene level (p less than 0.01). Subjects with subsequent stomach cancer had also lower mean vitamin C and lipid-adjusted vitamin A levels than survivors (p less than 0.05). Calculating the relative risk with exclusion of mortality during the first two years of follow-up, low plasma carotene was associated with an increased risk for bronchus cancer (RR 1.8, p less than 0.05), and the small number of stomach cancer cases (RR 2.95, p less than 0.05) low plasma levels of carotene and vitamin A with all cancer types (RR 2.47, p less than 0.01), and low plasma retinol in older subjects (greater than 60 years) with lung cancer (RR 2.17, p less than 0.05). Studies in other cohorts with a poor vitamin E status revealed an increased risk of subsequent cancer at low vitamin E levels as well. It is concluded that low plasma levels of all major essential antioxidants are associated with an increased risk of subsequent cancer mortality. Cardio-vascular mortality. Plasma carotene concentration below quartile 1 was associated with an increased risk for IHD (RR 1.53, p = 0.02). The same was true for low levels of both carotene and vitamin C (RR = 1.96, p = 0.022). The risk of cerebrovascular death was elevated in subjects with low carotene in the presence of low vitamin C plasma concentration (RR 4.17, p less than 0.01). These data confirm and extend recent findings on an inverse correlation of beta-carotene and vitamin C respectively to CVD.(ABSTRACT TRUNCATED AT 400 WORDS)

Plantwide analyses of the mortality experience of 8147 foundrymen revealed excesses for several diseases including lung cancer. Using indirect measures of smoking, it appeared that most, if not all, of the excess of lung cancer deaths could be explained by smoking habits. To explore further the possible association between these mortality excesses and foundry exposures, jobs were grouped into six work areas on the basis of similarities in production processes. The findings of analyses by work areas support the inferences from plantwide observations. No evidence was found of a relationship between lung cancer and foundry exposures. The pattern of mortality from emphysema and cerebrovascular disease in the different work areas paralleled that of lung cancer, suggesting that mortality from these diseases may have been influenced by a common etiologic agent, probably tobacco smoke. The data also reveal possible associations between metal pattern-making and colon cancer, silica or metal dust and stomach cancer, and carbon monoxide and ischemic heart disease.

Diseases presenting with dyspepsia fall into two general categories: organic and functional. Overall, most patients with dyspepsia have no underlying identifiable disease process. The diagnostic yield of organic causes is less in younger patients, and, conversely, serious organic lesions are common in elderly dyspeptic patients. The commonest organic causes of dyspepsia are peptic ulcer disease, gastroesophageal reflux, biliary tract disease, and gastric cancer. Symptoms and physical signs may help to differentiate these organic causes from functional dyspepsia but endoscopic or radiographic/ultrasound studies are usually necessary to ensure the appropriate diagnosis. Less common organic causes of dyspepsia not to be overlooked include drugs, pancreatitis, malabsorption syndromes, metabolic disorders, ischemic heart disease, and collagen vascular disorders.

A 78-year-old female was diagnosed as having an early gastric cancer of II a (+II c) type with probable sm invasion by gastroscopic examination. Endoscopic polypectomy was carried out due to advanced age, severe ischemic heart disease, and refusal of surgical treatment. Most of the cancerous tissue were removed endoscopically, but biopsy specimens after polypectomy showed some tumor cells leaving at the excisional site. She was treated with local injection of OK-432 endoscopically, PSK orally, Tegafur rectally, and Lentinan intravenously. After about 7 months' treatments, biopsy specimens revealed no residual cancer cells. The total doses administered up to cure for cancer were 70 KE of OK-432, 141 g of PSK, 99 g of Tegafur, and 45 mg of Lentinan. The combination therapy with massive removal of cancer tissue by endoscopy, local injection of anti-cancer agent to residual cancerous lesion and systemic immunochemotherapy will be available and recommendable for poor risk patients with early gastric cancer.

This is an autopsy report of multiple primary cancers observed in a patient who had clinically been diagnosed as chronic arsenic poisoning. An 88-year-old man, non-smoker, had worked in an arsenic mine for 6 years from the age of 47. He had undergone operations for Bowen's disease and gastric cancer at ages 80 and 86, respectively. At autopsy, squamous cell carcinoma of the lung and a polypoid lesion in the piriform recess were found. Furthermore, microscopic examination revealed latent prostatic adenocarcinoma and oncocytoma in the kidney. The polypoid lesion of the piriform recess appeared to originate from the duct of the minor salivary gland in the pharynx, showing an adenoid cystic carcinoma-like pattern with squamous cell carcinoma in part. The cause of death was thought to be respiratory failure due to bronchopneumonia and pulmonary edema as well as hydrothorax, and chronic heart failure following ischemic heart disease. Bowen's disease was followed by four internal malignant tumors, even though the etiological relation between these cancers and arsenic is not clear.

Although the rise in ischaemic heart disease in England and Wales has been associated with increasing prosperity, mortality rates are highest in the least affluent areas. On division of the country into two hundred and twelve local authority areas a strong geographical relation was found between ischaemic heart disease mortality rates in 1968-78 and infant mortality in 1921-25. Of the twenty-four other common causes of death only bronchitis, stomach cancer, and rheumatic heart disease were similarly related to infant mortality. These diseases are associated with poor living conditions and mortality from them is declining. Ischaemic heart disease is strongly correlated with both neonatal and postneonatal mortality. It is suggested that poor nutrition in early life increases susceptibility to the effects of an affluent diet.

Epidemiologic evidence shows a strong relationship between gastric cancer and cerebrovascular disease. It was speculated that salt intake might be the linking factor causing hypertension and vascular damage as well as damage to the gastric mucosa. This study tested whether hypertensive diseases, such as ischemic heart disease and cerebrovascular disease, occurred more frequently in patients with gastric cancer and gastric ulcer than expected by chance alone. In addition, it was studied whether gastric and duodenal ulcer coincided more frequently with other diseases that in the past have been associated with peptic ulcer, such as liver cirrhosis, chronic lung disease, and rheumatoid arthritis. The German statistics of rehabilitation were used to assess the frequency of coincidences. The statistics include a description of the primary, secondary, and tertiary diagnoses leading to rehabilitation. This study confirms the presence of a high coincidence of both ulcer types with liver cirrhosis. In patients with rheumatoid arthritis, both ulcer types also occurred more frequently than expected from their general distribution. Gastric but not duodenal ulcer coincided more frequently with ischemic heart disease than expected. Gastric cancer occurred more frequently in patients who had concomitant ischemic heart disease or cerebrovascular disease. Duodenal ulcer was not associated with an increased risk for any disease related to hypertension. The results of the study support the contention that gastric diseases and diseases related to hypertension share a common etiologic factor.

The specific causes of death for miners and ex-miners of the Rhondda Fach have been examined in detail using the data base provided by the 30 year follow up. The main findings are the lower specific mortality for those with category A, compared with those with categories 0, 1, 2, and 3, for all circulatory diseases (particularly ischaemic heart disease) and the raised mortality for gastric cancer. These results are surprising because a high proportion of those with, especially, categories 2 and 3 developed category A during the 30 years but fail to show the specific death rates typical of those with category A. Possible reasons for this are discussed and an explanation put forward.

In England and Wales there has been an increasing excess of ischaemic heart disease death rates among men and women of social classes IV and V compared with those in classes I and II and this excess is greater in young than in old adults. The male excess over women in IHD death rates is much greater in social classes I and II than in classes IV and V. Although men in professional occupations are at low risk for IHD compared with men in other occupations, women married to professional men are at an even lower risk compared with other women. Also, women married to men in unskilled occupations have relatively higher IHD rates than their husbands. These patterns are not seen for "all causes," cerebrovascular disease, chronic bronchitis, or stomach cancer, where the social class mortality gradients are similar in men and women. There may thus be factors associated with professional occupations that increase the risk of IHD despite the relatively low death rates of men engaged in them. In addition there may be factors operating in women in social classes IV and V that put them at a particularly high risk for the development of IHD.

In a study in 29 health centre districts in Japan 91 540 non-smoking wives aged 40 and above were followed up for 14 years (1966-79), and standardised mortality rates for lung cancer were assessed according to the smoking habits of their husbands. Wives of heavy smokers were found to have a higher risk of developing lung cancer and a dose-response relation was observed. The relation between the husband's smoking and the wife's risk of developing lung cancer showed a similar pattern when analysed by age and occupation of the husband. The risk was particularly great in agricultural families when the husbands were aged 40-59 at enrolment. The husbands' smoking habit did not affect their wives' risk of dying from other disease such as stomach cancer, cervical cancer, and ischaemic heart disease. The risk of developing emphysema and asthma seemed to be higher in non-smoking wives of heavy smokers but the effect was not statistically significant. The husband's drinking habit seemed to have no effect on any causes of death in their wives, including lung cancer. These results indicate the possible importance of passive or indirect smoking as one of the causal factors of lung cancer. They also appear to explain the long-standing riddle of why many women develop lung cancer although they themselves are non-smokers. These results also cast doubt on the practice of assessing the relative risk of developing lung cancer in smokers by comparing them with non-smokers.
