Stomach cancer in the United States has decreased over the last 50 years. It is still a major type of neoplasm in Japan, Eastern and Northern Europe, and parts of Latin America. Current concepts suggest that the reduction of gastric cancer in the U. S. stems from an increased consumption of foods with vitamin C on a year round basis, which is shown to antagonize the formation of putative gastric carcinogens. Risk factors for large bowel, breast, and prostate cancer are totally different from those for gastric cancer and thus are amenable to independent controls, with the goal of ultimately reducing the risk and preventing these major cancers in man. Current research aims to identify the nature of the mutagenic materials obtained during the frying of protein-containing foods. This process may be involved in the generation of carcinogens for cancer of the colon, breast, and prostate. Cancer of the colon is subject to somewhat different controlling elements than cancer of the breast because of the nature of the cell kinetics governing these tissues. Thus, the mechanism of action of diet involves lifestyle. The type, quality, and mode of cooking of food, particularly, play important roles in the etiology of the main human cancers in the gastrointestinal tract and the endocrine-sensitive organs.

Incidence rates of selected cancer sites reported by the California Tumor Registry and the New Mexico Tumor Registry are analyzed to study ethnic differences in cancer in the United States. The white majority population shows high incidence of lung and breast cancers. Black males show the highest prostatic cancer rate. Data also confirm the unusually high incidence of nasopharyngeal cancer and low prostatic cancer rates among Chinese males. The Japanese have the highest stomach cancer incidence among all the ethnic groups analyzed. A comparison with the cancer incidence in the same ethnic groups in their native countries reveals the impact of environmental or cultural changes on lung, breast, and stomach cancers, and a possible genetic influence on the high incidence of nasopharyngeal cancer among the Chinese population in the United States.

Cancer incidence rates by race, sex, and cancer site were obtained from the Third National Cancer Survey for the years 1969-71 for residents of Allegheny County, Pennsylvania. When the sex-site-specific rates for 1969-71, as well as incidence rates from surveys in the county in 1937, 1947, and 1957-58, were compared with U.S. rates for 1937, 1947, and 1969-71, a number of significant changes in incidence were observed. Male incidence of cancers of the lung, bronchus, and trachea increased steadily between 1937 and 1969-71 both in Allegheny County and the United States. In the county, female incidence rates for these cancers decreased in the period 1947 to 1957-58 but showed an average annual increased of 9.2 percent in the interval 1957-58 to 1969-71. Incidence rates for county males increased by an average of 4.4 percent per year from 1957-58 to 1969-71. For stomach cancer, incidence rates for both sexes have decreased sharply in the county and in the United States. In the county, stomach cancer rates for females declined by an annual average of 4 percent from 1957-58 to 1969-71, while those formales dropped 2.1 percent. There appears to have been a steady decline over time in cervical cancer in Allegheny County, although the average annual rate of decrease of 2.8 percent for the latest interval (1957-58 to 1969-71) is not as large as the decrease of 3.9 percent per year from 1947 to 1957-58. Breast cancer rates for the county appear to have been steadily, although slowly, increasing at an average rate of about 0.6 percent per year, in contrast to almost constant U.S. rates. The county's breast cancer incidence rate for 1969-71 almost equals the U.S rate. There have been steady increases in prostate cancer incidence in both Allegheny County and the United States since 1937. For all sites combined, male cancer incidence rates increased, while those for females slowly decreased in both Allegheny County and the United States during the interval 1937 to 1969-71. In the county, male rates for the interval 1937 to 1969-71 increased an average of 1 percent per year, while female rates declined approximately 0.3 percent annually.

We examined incidence time-trends for lung, stomach, intestinal, prostate, and breast cancer among Whites diagnosed in the United States between 1973 and 1987. For each sex and five-year age group, we modeled cancer incidence as a log-linear function of diagnosis-year to permit extrapolation over time and simple summarization of trends. Comparisons with nonparametric estimates show that, except for breast cancer, the model performs well. Plots of the annual percent change in incidence cf age illustrate the way in which time trends depend on age. Between 1973 and 1987, stomach cancer incidence decreased by about two percent per year. The annual change in lung cancer incidence progressed from a two to three percent decrease in persons under age 40 to an increase of two percent in men and eight percent in women by age 80. Intestinal cancer incidence decreased annually by as much as three percent in persons under age 50, remained constant in women aged 50 to 74, and otherwise increased about one percent per year. The annual increase in prostate cancer incidence declined from about six percent in men under age 40 to about two percent in men over age 80. After a surge in female breast-cancer diagnoses in 1974, the annual increase in incidence between 1980 and 1987 stabilized at four to six percent.

Regarding 249 bronchial asthma patients having been admitted to our division for the recent 9 years, clinical manifestations of 8 bronchial asthma with primary lung cancer (group A; squamous cell carcinoma--5 cases, adenocarcinoma--2 cases, small cell carcinoma--1 case; 3.2% of 249 cases) and 8 asthma patients with extrathoracic malignancy (group B; gastric cancer--3 cases, malignant lymphoma--2 cases, bladder cancer--1 case, laryngeal cancer--1 case, prostatic cancer--1 case) were investigated. In group A, the mean of asthmatic history was 19 years and all cases were associated with respiratory tract infections. Three of 8 patients, were mild type and other 5 were moderate type. In group B, the mean of asthmatic history was 20 years and all cases were involved with respiratory tract infections. Five of 8 patients were mild type and other 3 were moderate type. The mean smoking (Brinkmann) index (1194) in group A was significantly higher than that (166) in 241 asthmatic patients without lung cancer or that (169) in group B. The median survival duration (more than 26 months) of group A patients was significantly lower than that (more than 77 months) of group B. These results suggested that, in many bronchial asthma patients accompanied by primary lung cancer who have adult-typed infectious asthmatic history, smoking exposure and aging are deeply related to the development of lung cancer.

A cohort of 2,131 male nitrate fertilizer workers was evaluated for cancer morbidity from 1963 to 1986. No significant increase in total cancer, stomach cancer (5 actual vs 6.7 expected cases), or lung cancer (13 vs 13 expected) was found. On the other hand, 26 actual cases of prostate cancer were observed vs 16 expected cases (standardized morbidity ratio, SMR = 161; 95%, confidence interval, CI = 107-239). This risk increase however, was, not enhanced by applying at least a 10-year latency period. In a cohort of 1,148 male fertilizer workers who had never been exposed to nitrate, there was an increased incidence of lung cancer (SMR = 151,95% CI = 103-220) but not of stomach cancer or prostate cancer. There was no association between airborne nitrate exposure dose and total cancer, stomach cancer, lung cancer or prostate cancer, respectively.

Migration of Italians to other parts of the world has a long history and has involved very large numbers of individuals. The study of the health consequences of this migration is made possible by the availability of statistics on mortality and morbidity, both in Italy and in the host countries, and of social and economic information on the various Italian communities abroad. The results of the major studies are reviewed, comparing the rates in immigrants with those in the host countries and in Italy. The differences in cancer rates between Italian and local-born populations--for stomach cancer in both sexes, and for cancer of the colon, lung, and breast in females, and for prostate cancer--are consistent with the direction of differences between rates in Italy and those in the host countries. For colon and rectum cancer in males, there are unexpected findings in most of the United States' studies. Analysis by duration of residence shows changes in the risk for several sites in males, but not in females, according to length of stay in the host country. This finding possibly reflects greater stability of habits and lifestyle in females compared to males.

A review of 14,296 unselected bone scans identified 889 scans showing absent or faint renal uptake. The majority of cases were associated with renal insufficiency (816/889; 91.8%), while widespread metastatic bone disease was the most common cause in a group of patients without renal disease (53/889; 6.0%). Of the 140 patients with prostate cancer, 108 (77.1%) had evidence of bone metastasis, 19 of whom (17.6%) revealed absent or faint renal uptake, demonstrating that poor renal uptake is more frequently associated with prostate cancer than with any other malignancy. Of note was that 162 out of 328 (49.4%) patients with stomach cancer at varying stages showed evidence of bone metastasis, and 14 of them (8.6%) showed poor renal images on bone scan. Interestingly, ankylosing spondylitis and rheumatoid arthritis were occasional causes of lack of renal activity (4 and 3 cases, respectively). A case of adult-form osteopetrosis, showing strikingly increased uptake mainly in the long bones with markedly diminished renal uptake, was also included in this study. Of the 53 bone scans with metastatic disease showing poor renal uptake, 44 (83.0%) revealed evidence of diffuse or multiple metastases in both spine and ribs, while 49 (92.5%) showed malignant involvement in three or more regions and 35 (66.0%) in four or more regions, suggesting widespread bone involvement in most cases.

Mortality rates in the USSR for the major cancer sites have been computed for the period 1986-88 from official numbers of certified deaths and population estimates provided by the World Health Organization databank, and compared with rates for 26 other European countries. Among males, elevated mortality rates (age-adjusted, world standard) were observed for cancer of the oral cavity and pharynx (6.6/100,000), oesophagus (8.4/100,000) and larynx (6.8/100,000). Mortality from cancer of the stomach (38.4/100,000 males and 16.5/100,000 females, for a total of 87,000 deaths per year) was the highest in Europe. Likewise, overall lung cancer rates among males (61.0/100,000, for over 77,000 deaths per year) were among the highest in Europe, and showed substantial rises over the last 2 decades. Lung cancer mortality in females was comparatively low (6.9/100,000), and increased only moderately. Rates for cancers of the intestine (14.6/100,000 males and 10.6/100,000 females) and of the female breast (12.9/100,000) were comparatively low as compared to most other European countries, and those for prostatic cancer (5.9/100,000) were the lowest registered in Europe. In contrast, mortality for cancer of the uterus (9.7/100,000) was among the highest in Europe, probably due to high mortality from cervical cancer. Priorities for cancer control in the Soviet Union are thus reduction of consumption of tobacco and alcohol, which largely explain the high rates for lung and upper digestive and respiratory sites, improvements in diet composition and food storage to reduce the substantial excess of stomach cancer, and rational screening for cervical cancer.

To investigate whether a history of hematolymphoproliferative cancers (HLP) and other cancers among a parent or sibling is a risk factor for specific subtypes of leukemia and non-Hodgkin's lymphoma (NHL), data from a population-based case-control study, in Iowa and Minnesota, of 578 leukemia cases, 622 NHL cases and 1245 controls were evaluated. Having at least one sibling with HLP significantly increased the risk for all leukemias combined (odds ratio (OR) = 2.3) and for NHL (OR = 2.7). In particular, chronic lymphocytic leukemia (CLL) was significantly increased among those reporting a sibling with leukemia (OR = 3.0) or lymphoma (OR = 4.3). Elevated risks of small lymphocytic NHL (SML) (OR = 7.3) and diffuse NHL (DIF) (OR = 5.4) were also observed among subjects who had a sibling with lymphoma (primarily Hodgkin's disease). A significantly increased risk of follicular NHL was noted among those with a sibling history of pancreatic cancer (OR = 4.8) and colorectal cancer (OR = 2.7). Parental history of HLP was not associated with any type of leukemia or NHL. A history of stomach cancer among parents was associated with a 2-fold elevation of CLL and DIF compared to controls. Increased risks of CLL and DIF were also linked to breast cancer among sisters and mothers, respectively. Prostate cancer among fathers increased the risk 2-fold for CLL and 3-fold for SML. This study confirms some familial cancer associations previously reported for leukemia and NHL, and provides new information regarding the various subtypes of leukemia and NHL.
