Serum copper and ceruloplasmin levels (SCL, SCeL) in 57 patients with advanced cancer of the stomach (35 cases) or large intestine (22 cases) treated with polychemotherapy were studies. In gastroenteric cancer, SCL, which are already high in untreated patients, have a tendency to increase further in cases of progression of the disease, while they seem to significantly decrease in cases of remission. SCeL during the trial appeared to be correlated to the clinical evolution of the disease only in the case of stomach cancer. In large intestine cancer, SCeL did not show any significant variation in relation to the normal range. These observations, in particular on the behavior of SCL in the neoplasms of the digestive tract, are in accordance with the results of other studies. The authors are inclined to attach a diagnostic and prognostic value to the variation in SCL and SCeL in gastrointestinal cancer.

The serum copper levels were investigated in 125 patients with solid tumors: 34 patients with bronchial cancer, 35 with gastric cancer, 31 with breast cancer and 25 with melanoma. Analysis showed that serum copper was extremely high in 82% of the patients with bronchial carcinoma, while in the other examined groups no significant changes were observed. According to these results, serum copper could be a diagnostic factor in patients with bronchial carcinoma.

Sex-specific mortality rates for selected cancer sites (including oesophagus, stomach, liver, lung, colorectum, breast and cervix) and a variety of biochemical indicators of antioxidant status, enzyme activity and oxidative stress (including plasma levels of beta-carotene, alpha-tocopherol, ascorbic acid, selenium, glutathione peroxidase, catalase, superoxide dismutase, iron, copper, zinc, total cholesterol and lipid peroxide) were examined in an ecological study of 65 mostly rural counties in the People's Republic of China. The wide range of both mortality rates and biochemical values and the measurement of a comprehensive set of biochemical indicators permitted both simple correlational and multivariate analyses of the joint and relative effects of each factor on site-specific cancer mortality. Plasma levels of dietary antioxidants were consistently negatively correlated with cancer mortality rates. Ascorbic acid was most strongly negatively associated with most cancers and selenium with oesophageal and stomach cancers. beta-carotene was found to have a protective effect independent of retinol, particularly for stomach cancer.

This study was performed to find out whether copper, zinc, manganese, selenium and iron concentrations in the cancerous and normal stomach tissues of the patients with stomach cancer vary within the malignant stages and Borrmann classification or not, and to investigate the interaction of copper, zinc, manganese, selenium and iron concentrations in blood of these patients. Copper concentration in cancerous tissues was not statistically significant as compared with normal tissues. Plasma and whole blood copper concentration of Stage IV showed a significant higher level than that of stage I. Zinc concentration in cancerous tissues was not statistically significant as compared with normal tissues. Selenium concentration in cancerous tissues showed a statistically significant high level as compared with that in normal tissues. Plasma selenium concentration of Stage III showed a significant lower level than that of stage I. Iron concentration in cancerous tissues showed a significantly lower level than that in normal tissues at stage IV. Whole blood iron concentration was low levels in proportion to the progress of stomach cancer. The correlation of selenium concentration between in cancerous tissues and in whole blood of these patients was significant with the correlation coefficient of 0.340. The correlation of iron concentration between in cancerous tissues and in whole blood of these patients was significant with the correlation coefficient of 0.423. The correlation between iron concentration in cancerous tissues and hemoglobin concentration in whole blood of these patients was significant with the correlation coefficient of 0.361.

An ecological survey on diet, life style and cancer mortality was carried out in 65 rural counties in China, using a questionnaire comprising 285 questions on environmental factors, dietary practices and other life style characteristics; in addition, blood, urine and food were collected and analysed. Two interpretations of preliminary data are presented. One is for the finding of a positive correlation between a latent variable, namely general nutritional status, and cancer mortality rates; the other is for a positive correlation between lipid peroxidation (plasma lipid peroxidase and copper) and oesophageal and gastric cancer mortality, and a negative correlation between dietary oxidants (plasma selenium, ascorbic acid and retinol) and mortality from oesophageal and gastric cancer.

Trace element (TE) content (zinc, copper, selenium, chromium) in different body media during surgery and anesthesia has been studied in 56 patients with esophageal and gastric cancer. It has been established that the components of modern analgesia have different effects on intra- and extracellular zinc, copper, selenium and chromium migration. Hexenal decreases TE blood plasma level and simultaneously increases their erythrocyte concentration. The administration of the first doses of depolarizing myorelaxants causes an increase in blood plasma and a decrease in erythrocyte zinc, copper, selenium and chromium content. Subsequent doses of depolarizing myorelaxants have no such effect. The most traumatic moment of the operation is accompanied by an increase in blood plasma and a decrease in erythrocyte TE content. Upon the operation and anesthesia the TE levels under study reach baseline values. In the first 24 hours after surgical intervention there is a decrease in TE erythrocyte concentration and an increase in their blood plasma and daily urine content.

The immunohistochemical localization of copper, zinc-superoxide dismutase (Cu,Zn-SOD) in human gastric mucosa and gastric cancer was studied using a monoclonal antibody. In gastric mucosa, parietal cells, pyloric glandular cells and foci of intestinal metaplasia showed positive staining in the cytoplasm and/or nucleus. The wide distribution of Cu, Zn-SOD in the gastric mucosa suggests cell function may be vulnerable to active oxygen species. In gastric cancer, 34 of 70 cases showed a positive reaction for Cu, Zn-SOD. There was a relationship between the grade of Cu,Zn-SOD immunoreactivity and the histological type of gastric cancer, well-differentiated types of gastric cancer being more frequently positive. The positive cases of poorly-differentiated adenocarcinoma were characterized by a pattern of diffusely infiltrative invasion. These results suggest that some types of gastric cancer are resistant to active oxygen species.

Cancer mortality was studied among 265 male workers in 40 small plating factories (chromium, copper and nickel) where bicycle parts are plated. The study utilized record linkage with the Osaka Cancer Registry file between January 1, 1965 and December 31, 1979. The results showed that seven workers had died of cancer, and the Standardized Mortality Ratio (SMR) calculated for all cancers, stomach cancer and lung cancer were 1.13, 1.23 and 1.11, respectively, with no significant relationship found between the observed and expected values. The SMR for lung cancer among those workers with a high degree of skin ulceration and with perforation of the nasal septum was high, 11.22 and 5.13, respectively, although not statistically significant because of the small sample size in the study. The results suggest that lung cancer occurs in those subjected to a high degree of exposure to chromium.

The serum copper and zinc Levels of 35 cases of gastric cancer were measured pre- and postoperatively, and Cu and Zn Levels in their gastric juice were also determined Preoperatively. The results Showed that serum copper Levels (SCL) and Cu/Zn ratios of patients with gastric cancer were significantly higher, while serum zinc levels (SZL) lower than those of the control. In addition, SCL of patients with gastric cancer elevated progressively as the cancer advanced. After resection of the tumor, SCL and Cu/Zn ratio declined and SZL elevated again. The Cu and Zn levels in the gastric juice, of benign gastric lesions showed more marked elevation and gastric cancer patients had higher Zn level than those in the normal controls.

Serum zinc and copper levels were evaluated in patients with gastric cancer who had undergone gastrectomy. These patients were divided into two age categories; namely, the aged group, comprising 39 patients over the age of 70 years, and the younger group, comprising 23 patients younger than 50 years. The data before and after surgery were compared between the two groups. Serum zinc levels in the aged group were significantly lower than those in the younger group, both before and after surgery. Serum copper levels, however, did not differ significantly between the two groups. The serum Cu/Zn ratio was also analyzed according to the histological stages of cancer (stages I to IV), and compared between the two age-classified groups. The aged group showed a higher Cu/Zn ratio at all stages, whereas in the younger group, the ratio was significantly higher at stage IV than in the earlier stages. Preoperative serum zinc, copper, and the Cu/Zn ratio were studied in relation to the complication of anastomotic leak after surgery. The Cu/Zn ratio in the aged patients with this complication was significantly higher than that in the aged patients without it. These results suggest that the Cu/Zn ratio may be an important factor in determining nutritional parameters in the aged.
