Trends in cancer incidence and mortality in the United States were analyzed over the period 1969 through 1976. The greatest increase in incidence among whites occurred for lung cancer among females (almost 9%/yr), whereas the incidence of cancer of the uterine corpus increased 6% per year. Cancer of the cervix showed the greatest decrease in incidence, an average of 6% per year. Stomach cancer incidence and mortality showed a substantial decline for each sex, and rectal cancer incidence increased for each sex whereas mortality declined. The incidence of cancer of the female breast increased 1.8% per year without inclusion of the rates for 1974 and 1975, when an unusually large increase occurred. Cancer mortality data were presented for the total United States on the basis of data from the National Center for Health Statistics. Emphasis was focused on the comparability of cancer incidence data over the time period studied, given the fact that cancer incidence was measured by the Third National Cancer Survey for the period 1969-71 and by the Surveillance, Epidemiology, and End Results Program for the period 1973-76. Each survey covered approximately 10% of the U.S. population but had four geographic areas in common. Investigation of the comparability of these two surveys revealed that the incidence rates for whites were sufficiently comparable to permit an analysis of trends in cancer incidence over the entire period 1969-1976. Such comparability was not found for blacks. Therefore, cancer incidence data are presented only for whites, but cancer mortality data are presented for both whites and blacks.

Among 1,047 women fluoroscopically examined in average of 102 times during pneumothorax therapy for tuberculosis and followed up to 45 years (average = 27 yr), no increase in the total number of cancer deaths occurred when these women were compared to 717 women who received other treatments [relative risk (RR) = 0.8]. However, elevated risks of mortality from stomach cancer (RR = 2.3), rectal cancer (RR = 3.8), breast cancer (RR = 1.2), lung cancer (RR = 1.8), and leukemia (RR = 1.2) were observed, but none was statistically significant and all were based on very small numbers of deaths. These increases were balanced by decreases of genital cancer (RR = 0.2), pancreatic cancer (RR = 0.9), lymphoma (RR = 0.6), and all other cancers (RR = 0.1). Average cumulative absorbed doses were 110 rads for the lungs, 33 rads for the trunk, 13 rads for the active bone marrow, and 7 rads for the stomach. The following upper levels of excess risk could be excluded with 95% confidence: 3.5 deaths/10(6) woman-year (WY)-rad for lung cancer, 4.8 deaths/10(6) WY-rad for lymphoma, and 12 deaths/10(6) WY-rad for leukemia. These findings indicated that the carcinogenic effect of multiple low-dose X-ray exposures was not greater than that currently assumed.

The studies of levels of circulating immunoglobulins in cases of solid neoplasia in man have yielded discordant results, especially in cases of colon and rectal cancer. The possible prognostic value of the quantitation of these parameters has been discussed, and some have even suggested that certain fluctuations in immunoglobulin levels may indicate the development of metastases. We studied the behavior of humoral immunity in 88 patients with gastric adenocarcinoma, 63 patients with cancer of the colon and 60 healthy controls. The cancer patients were grouped according to tumor stage. Serum levels of IgG, IgA and IgM were determined in the preoperative period. The results show a significant decrease in IgG titers in all stages of gastric cancer but more so in the initial stages of development. In the cases of cancer of the colon, the IgG reduction was most evident in the advanced stages of disease. IgA levels were significantly elevated in stage III of gastric cancer and all stages of cancer of the large intestine. IgM levels in gastric cancer behave in a similar manner as IgA, and is elevated in the final stages of cancer of the colon.

The incidence of gastrointestinal cancers differ greatly internationally. Blacks have higher rates than whites for esophagus, stomach, liver, and pancreatic cancer in the U.S. Differences also occur between other racial groups. Studies on migrants suggest environmental causes for these differences. Stomach cancer rates have fallen, intestine cancer is stable, pancreatic cancer rates rose, but are now falling in males. The incidence of colon, rectal, breast, corpus-uterus, ovary, and prostate cancer are positively correlated, but colon or rectal and stomach cancer are negatively correlated. Colon and rectal cancer mortality are positively and stomach cancer negatively associated with social class. Esophageal, liver, colon, and pancreatic cancer in males are higher in urban areas. Seventh Day Adventists and Mormons show a low risk of colon cancer. Internationally intake of fat is correlated with colon, rectal, and pancreatic cancer, and starch with stomach cancer.

Urinary pseudouridine/creatinine ratio was determined in 74 patients with gastrointestinal tumours and 34 patients with no known malignant disease. The reproducibility of a single random urine sample was demonstrated. The mean ratio for control patients was 26.9 +/- 7.7 nmol/mumol and no control patient exceeded the mean by 2 standard deviations. There was no difference in the ratio between the sexes. Sixty-five per cent of colon cancer patients and 37.5 per cent of gastric and rectal cancer patients exceeded this upper limit of normality. There was no correlation between pseudouridine/creatinine ratio and histological differentiation, liver involvement or stage in either colorectal or gastric cancer patients. Urinary pseudouridine/creatinine ratio is one of the better non-specific cancer markers and may be particularly useful for detecting colonic cancer.

The relationship between gastrointestinal cancers and genetic influence was investigated. The subjects examined were 1211 cancer cases and 781 non-cancer cases registered to the 1st Department of Surgery of Kagoshima University Hospital from 1972 to 1980. The results were as follows: 1. Malignant cases were found in 266/1211 (22.0%) in the families of cancer probandus. Incidence was significantly (P less than 0.01) higher than that [130/781 (16.6%)] in those of non-cancer probandus. 2. Malignant cases were found in 79/356 (22.2%) in the families of gastric cancer probandus and in 51/189 (27.0%) in those of colo-rectal cancer probandus. 3. The relationship between cancer probandus and malignant cases in the families was classified according to the vertical relationship (grandparents-parents-uncle and aunt-probandus-children) and the horizontal relationship (probandus-siblings-cousin). 4. Incidence in the vertical relationships (159/266: 59.8%) was higher than that in the horizontal relationships (107/266: 40.2%). Incidence of the vertical relationships of female cancer probandus (gastric cancer: 70.4%, esophageal cancer: 55.7%, clorectal cancer: 73.9%) was significantly (P less than 0.05) higher than that in those of male cancer probandus. 5. Incidence of blood B type in male gastric cancer group tended to be less when compared with the control group (P less than 0.05). 6. Incidence of smoking habits in esophageal cancer group (82.2%) and the lung cancer group (63.4%) was significantly (P less than 0.01) higher than that in the control group (46.0%). 7. Incidence of drinking habits in the male esophageal cancer group (84.2%) was significantly (P less than 0.01) higher than that in the control group (53.0%).

Regressive computer analysis was used for prognostic evaluation of immediate and long-term results of radical treatment of gastrointestinal cancer of different localization. The data were derived from 1,630 patients with gastric, colonic, and rectal cancer who were radically operated upon at N.N. Petrov Oncological Research Institute, the USSR Ministry of Health. A prognostic formula was suggested and verified for determination of the period of greatest risk of gastric cancer recurrences and metastases. Formulae were also devised for foreseeing the degrees of postoperative risk in patients with gastric, colonic, and rectal cancer.

Thirteen cases of carcinoid of the GI tract during eleven years seen in our hospital are presented. Prior to surgery, the clinical diagnosis of our 9 cases of gastric carcinoid was as follows: 7 cases were diagnosed as advanced gastric cancer, one case as perforated gastric ulcer, while a minute lesion of less than 1 cm in diameter was correctly diagnosed as a carcinoid. The tumors were all larger than 2 cm in the largest diameter with the exception of a minute lesion that appeared as a submucosal tumor and was diagnosed correctly before operation. Only one case of rectal carcinoid was diagnosed as a carcinoid endoscopically. The other two were diagnosed as rectal polyp and rectal cancer respectively. The lesion arising in the cecum was diagnosed as cecum tumor. The biopsy specimens of most carcinoids revealed adenocarcinoma pre-operatively, and only two cases were diagnosed correctly as carcinoid. In our series, we were unable to detect any symptom or sign of carcinoid syndrome, even in the case with widespread liver metastasis. We have not encountered any case of carcinoid in the appendix, which lesion has been very frequently reported in the Western countries.

Mortality figures for tumours of the stomach and colon-rectum in Italy over a 20 year period and divided by age classes, show a reduction in gastric cancer (-33%) and an increase in colo-rectal cancer (+63%). The incidence of mortality by region (greater in the North, less in the South) and town is analysed. Possible relations between varying customs and the onset of tumours in different sites of the gastro-enteric apparatus are recalled.

Under study was the functional activity of the sympatho-adrenal system in identical surgical interventions in 44 gastric cancer patients and 77 rectal cancer patients, operated under nitrogen monoxide-ether, nitrogen monoxide-fluothane anesthesia and under neuroleptanalgesia supplemented with nitrogen monoxide. The sympatho-adrenal activity was assessed, taking into account the content of total catecholamines (adrenaline and noradrenaline) in blood and urine prior to surgery, intraoperatively before anesthesia, during the most traumatizing moment of the operation and at 1, 3, 6 day after it. It was found that in identical operative procedures stimulation of the sympatho-adrenal system is mostly manifest in patients operated upon under either anesthesia and neuroleptanalgesia. Use of fluothane narcosis in gastric cancer patients produced no marked activation of the sympatho-adrenal system, while in rectal cancer patients it was not so significant as in either narcosis and neuroleptanalgesia.
