The Chilean population exhibits a very low risk for colo-rectal cancer. The farm workers have a high-fibre, low-saturated-fat diet and also an extremely low age-adjusted death rate for colonic and rectal cancer, in each sex. A highly significant positive correlation between age-adjusted death rates from arteriosclerotic heart disease in males and colonic and rectal cancer death rates suggests that high levels of saturated fats and/or cholesterol in the diet may be incriminated for high death rates from large bowel cancer. It is concluded that high plant fibre content and low levels of saturated fats and/or cholesterol in the diet may be important factors influencing the very low age-adjusted death rates from colo-rectal carcinoma in Chilean farm workers.

The purpose of this study was to investigate the relationship between life style factors and adult diseases among three ethnic groups, Chinese living in Japan, Koreans living in Japan and Japanese. The mortalities of major cancers and other adult diseases of Chinese and Koreans in Japan were compared with those of Japanese by calculating Standardized Mortality Ratios (SMR) of the two groups using death rates in the Japanese population as the standard. Life style data on smoking, drinking and dietary habits of the three groups were collected by self-administered questionnaire surveys, and age-adjusted proportions were calculated with the truncated world population as the standard. The results are summarized as follows: 1. The mortality rates for liver cancer, lung cancer, diabetes mellitus, heart disease, hypertensive disease, cerebrovascular disease and liver cirrhosis for Koreans of both sexes in Japan were significantly higher than those for Japanese, but the mortality rates of stomach cancer, pancreatic cancer and breast cancer for Korean females were lower than those for Japanese females. 2. The mortality rates for heart disease, diabetes mellitus, hypertensive disease, liver cirrhosis, rectum cancer, liver cancer, lung cancer (females), breast cancer (females) and cerebrovascular disease (females) for Chinese in Japan were higher than those for Japanese, but the rates for stomach cancer, pancreatic cancer (both sexes), uterus cancer (females) and cerebrovascular disease (males) were lower than those for Japanese. 3.(ABSTRACT TRUNCATED AT 250 WORDS)

This study was conducted to investigate the relationship between life style factors and adult disease for Chinese living in Japan. The mortalities of major cancers and other major diseases of Chinese in Japan were compared with those of Japanese by calculating Standardized Mortality Ratios (SMR) for the Chinese using death rates in the Japanese population the standard. The life style data on smoking, drinking and dietary habits for Chinese in Japan were collected by self-administered questionnaire surveys, and age-adjusted proportions were calculated with the truncated world population as the standard. Then the corrected indexes on life style for Chinese in Japan were compared with those of Japanese. The results are summarized as follows: 1. The mortality rates of heart disease, diabetes mellitus, hypertensive disease, liver cirrhosis, rectum cancer, liver cancer (both sexes), lung cancer (females), breast cancer and cerebrovascular disease (females) for Chinese in Japan were higher than those for Japanese, but the rates of stomach cancer, pancreas cancer (both sexes), uterus cancer (females) and cerebrovascular disease (males) were lower than those for Japanese. 2. The prevalence of current smokers for Chinese males in Japan was lower than that of Japanese, and that of females was higher than that of Japanese. The prevalence of non-smokers for Chinese males was higher than that of Japanese, and that of females was lower than that of Japanese. 3. Although the prevalence of regular drinkers for Chinese of both sexes in Japan were lower than that of Japanese, the prevalence of heavy drinkers who drank over 80 ml of ethanol every day for Chinese males was higher than that of Japanese males. 4. Significant differences were not found in the prevalences of frequent consumers of meat, milk, eggs, fish, other vegetables and food using oil between cooks and non-cooks of Chinese of both sexes in Japan. 5. The age-adjusted prevalences of frequent meat and milk consumers for Chinese in Japan were higher than those of Japanese in both sexes, but those of frequent pickled vegetable and MISO soup consumers were lower than those of Japanese. The dietary pattern of Chinese in Japan was different from that of Japanese with intakes of much fat and less salt. 6. It is assumed that the mortalities due to adult disease for Chinese in Japan are related to their heavy drinking and to their dietary habits.

Family history data of colorectal cancer, heart disease, and stroke were obtained on near relatives (parents, siblings, and children) in 702 colorectal cancer cases and 710 age-/sex-matched community controls as part of a large, comprehensive, population-based epidemiological and clinicopathological study of colorectal cancer conducted in Melbourne (the Melbourne Colorectal Cancer Study). There was a statistically significant higher family history rate of colorectal cancer in cases than in controls (relative risk = 2.13; 95% confidence interval = 1.53-2.96; p less than 0.001). This family history effect was more pronounced for colon cancer than for rectal cancer and there was an earlier age of detection of colorectal cancer in those with a family history of this cancer when compared with those without such a history. Dietary risk factors for colorectal cancer, which were previously described in the Melbourne study, were separate and independent from the family history effects. It is concluded that a family history of colorectal cancer is an important indication to screen individuals for this cancer, and also that while heredity has a definite role in the etiology of colorectal cancer, this hereditary effect is either likely to be small, or else likely to be important in only a proportion (perhaps 20%) of cases.

The associations between colorectal cancer risk and several chronic illnesses, operations, and various medications were examined in 715 colorectal cancer cases and 727 age/sex-matched controls in data derived from a large, comprehensive, population-based study of this cancer conducted in Melbourne, Australia. There was a statistically significant deficit among cases of hypertension, heart disease, stroke, chronic chest disease, and chronic arthritis and a statistically significant excess of "hemorrhoids" among cases, and all of these differences were consistent for both colon and rectal cancer and for both males and females. Although no statistically significant differences were found for other cancers, there were twice as many breast cancers among cases (16) than among controls and also there were 9 uterine cancers among cases and only 2 among controls. There was a statistically significant deficit among cases in the use of aspirin-containing medication and vitamin supplements, and this was consistent for both colon and rectal cancer and for both males and females. There was a statistically significant excess of large bowel polypectomy among cases. The modeling of these significant associations simultaneously in a logistic regression equation indicated that hypertension, heart disease, chronic arthritis, and aspirin use were each independent effects and consistent for both colon and rectal cancer for both males and females and also that these effects were independent of dietary risk factors previously described in the Melbourne study. The possible relevance of these findings towards an understanding of colorectal cancer risk and etiology is discussed.

The characteristics of 702 colorectal cancer patients are described in relation to the presence of absence of a family history of colorectal cancer in near relatives. No statistically significant associations were found between those with a family history of colorectal cancer and age at detection, sex, country of birth, religion, number of cancers (single, synchronous, or metachronous), previously removed benign colorectal polyps, and adenomatous polyps found in the resection specimen. The family history rate of colorectal cancer for colon cancer cases was statistically significantly higher than for rectal cancer cases (chi 2(1) = 3.8, P = .05) and there was a gradient of decreasing risk from colon to rectum. The family history rate of colorectal cancer in parents of those who were less than 50 years old was twice that of those 50 or older (P = .07), consistent with the view that earlier age of onset is a characteristic of those with a family history of colorectal cancer. There was a statistically significantly higher family history rate of colorectal cancer in respondents who knew of the disease compared with those who did not (chi 2(1) = 5.5, P less than .05). It is unclear if this effect represents recall bias or self-selection bias. In contrast, the rates for a family history of heart disease and stroke were similar, irrespective of the respondent's knowledge of their colorectal cancer status. Thus in the Melbourne study, the family history rate of colorectal cancer was higher in colon cancer than in rectal cancer, there was a decreasing gradient of risk from colon to rectum, and a tendency for earlier age of onset of colorectal cancer in those with a history of this cancer in a parent.

The easy-to-use statistical package has imposed a new hardship on the clinical researcher: too much complicated analysis. The problem is most acute in the interpretation of multivariate results that select a combination of several factors that "best" predict or explain medical outcomes. For example, these methods give rise to formulas that 1) weigh together the risk factors of smoking, blood pressure, and lipid levels as determinants of heart disease, or 2) construct from pathologic and clinical evidence a prognostic profile for disease-free rectal cancer patients. To help the clinician apply these methods, we propose that, on request, statistical packages also produce two sets of calculations that validate the primary analysis: 1) a set of simple tabulations that show how the factors and outcomes used in the primary analysis relate to one another, and 2) the results of alternative analyses that show factors which every analysis selects, factors which only appear in the primary analysis, and those which tend to substitute for one another.

Body size is associated with the risk of many diseases, including diabetes, heart disease, and some cancers. To evaluate the association of body size with large bowel cancer, height and weight measurements were ascertained by telephone interview from 779 Wisconsin (United States) women with newly reported diagnoses of carcinoma of the colon and rectum. Controls (n = 2,315) interviewed for this case-control study were selected randomly from Wisconsin driver's license files and Health Care Financing Administration files. The effects of weight and height were examined using multiple logistic regression to control for potential confounding variables. In this study, weight adjusted for height increased the risk of colon cancer (odds ratio [OR] for 72.57-148.33 kg cf 36.29-58.05 kg = 1.4, 95 percent confidence interval [CI] = 1.0-1.9) but did not increase the risk of rectal cancer. Height did not influence risk for cancer of either the colon or the rectum. Left-colon subsite analysis showed especially strong associations with current weight and with percent change in weight since age 18. These data suggest that a dose-response relationship exists between body size and risk of colon cancer in women; body size did not appear to influence risk of rectal cancer.

The life expectancy of women currently exceeds that of men by almost seven years, yet women spend approximately twice as many years disabled prior to death as their male counterparts. The diseases that account for death and health care utilization in older women (heart disease, cancer, stroke, fracture, pneumonia, osteoarthritis, cataracts) are also major contributors to disability. This paper reviews the scientific evidence that supports specific recommendations for older women that may prevent or delay these conditions for as long as possible. Risk factors for falls and fractures should be assessed and, where possible, modified. Adequate intakes of calcium, vitamin D, fruits, and vegetables should be encouraged. Weight should be monitored and weight loss discouraged for most women. Screening for B12 deficiency is recommended. Engaging women in a shared decision-making process about the use of hormone replacement therapy for longterm prevention of heart disease and fractures is important, as is regular screening for breast and colo-rectal cancer. Women should be encouraged to engage in enjoyable physical activities, including walking, for 30 minutes daily. These interventions have the potential to delay the onset and improve the course of many chronic conditions that prevail in later life.

The need for cardiac surgery among patients undergoing treatment for advanced digestive cancer is limited to the following situations:(i) heart diseases that can be life threatening if left untreated and that cannot be cured by medicinal treatment alone (e.g., cardiac tumors) and (ii) heart diseases (e.g., infectious endocarditis and pulmonary thromboembolism) occurring after digestive cancer surgery that need emergency treatment and that are resistant to medicinal treatment. We encountered 2 cases that required cardiac surgery.( Case 1) A 68-year-old woman with advanced gastric carcinoma accompanied by pyloric stenosis and left atrial myxoma underwent radical surgery for gastric cancer( Stage IIIA). Subsequently, the left atrial myxoma was resected before adjuvant chemotherapy for the treatment of gastric cancer was administered. One month after the surgery, multiple liver metastases appeared. However, they disappeared after chemotherapy was completed, and the patient survived for more than 3 years with complete response. (Case 2) A 67-year-old woman who underwent a Hartmann operation for obstructive rectal cancer (Stage II) experienced infectious endocarditis after the surgery. Because the endocarditis was resistant to medicinal treatment and acute heart failure was anticipated, cardiac surgery was performed. Approximately 2 months after the surgery, the bacilli( methicillin-resistant Staphylococcus aureus [MRSA]) were not found in blood culture. However, multiple liver metastases appeared immediately after the disappearance of the bacilli, and the patient died 3 months after the surgery. In both cases, cancer recurrence occurred early after cardiac surgery. Excessive surgical stress due to cardiac surgery may have promoted cancer recurrence. A decision pertaining to the timing of cardiac surgery is difficult in cases of patients with advanced digestive cancer and co-existing heart disease, which cannot be cured by medicinal treatment.
