A collaborative case-control study of nutrient intake and pancreatic cancer within the search programme.

Case-control studies of pancreatic cancer were conducted in 5 populations with moderate to high rates and differing dietary practices, using a common protocol and questionnaire. Comprehensive diet histories were completed for a total of 802 cases and 1669 controls identified in Adelaide (Australia), Montreal and Toronto (Canada), Utrecht (The Netherlands) and Opole (Poland). Positive associations were observed with intake of carbohydrates and cholesterol, and inverse associations with dietary fiber and vitamin C. These relationships were generally consistent among the 5 studies, and showed statistically significant and generally monotonic dose-response relationships. The relative risks for highest vs. lowest quintile of intake were estimated for carbohydrates to be 2.57 (95% confidence interval 1.64-4.03), cholesterol 2.68 (1.72-4.17), dietary fiber 0.45 (0.30-0.63), and vitamin C 0.53 (0.38-0.76). The consistency, strength, and specificity of these associations provides evidence for the hypothesis that some or all of these dietary factors may alter the risk of pancreatic cancer.

[Diabetes mellitus and pancreatic cancer: a case-control study in greater Montreal, Quebec, Canada].

In a population-based case-control study of dietary risk factors in French Canadians in Montreal, a total of 179 cases and 239 controls were interviewed between 1984 and 1988. It was found that the frequency of diabetes was almost three times higher in cases of pancreatic cancer (16%) than in the controls (6%), with an Odds Ratio (OR) of 2.52 and a Confidence Interval (CI) of 1.04-6.11. Fifty per cent of the pancreatic cancer cases had this disease before the cancer was diagnosed, compared with 71% of the controls at the time of the study. Those aged 50 years and over accounted for 75% of the cases and 71% of the controls (diabetic subjects); 68% of the cases were treated with a combination of diet and oral hypoglycemic agents compared with 86% of the controls. Insulin was used by 32% of the cases and 14% of the controls. These results suggest that diabetes may play a major role in the etiopathogenesis of pancreatic cancer in this urban population. A lot of controversy remains about the precise role of diabetes, and further studies are needed for a better assessment and understanding of the mechanisms of this association.

Tobacco, alcohol, and coffee and cancer of the pancreas. A population-based, case-control study in Quebec, Canada.

A population-based, case-control study of pancreatic cancer was carried out in greater Montreal between 1984 and 1988. A total of 179 cases and 239 population-based controls were interviewed. This study was part of the SEARCH program of the International Agency for Research on Cancer of the World Health Organization. A strong positive association was observed between total cigarette smoking and risk of pancreatic cancer (odds ratio [OR] = 3.76; 95% confidence interval [CI], 1.80 to 7.83). The OR for current smokers in the highest quintile of number of cigarettes was 5.15 compared with 3.99 for exsmokers. Those who consumed alcohol were in general at lower risk than nondrinkers. Coffee drinkers were collectively at lower risk than nondrinkers, particularly when coffee was consumed with meals, not on empty stomach.

Nutritional factors and pancreatic cancer in the francophone community in Montréal, Canada.

In a population-based case-control study of dietary risk factors for pancreatic cancer, a total of 179 cases and 239 controls were interviewed between 1984 and 1988. This study demonstrated an increased risk of pancreas cancer associated with high levels of reported energy intake. After adjustment for age, sex, response status, lifetime cigarette consumption and energy intake, there appeared to be an association with total fat intake (odds ratio in highest quartile relative to lowest quartile 2.24 [95% Confidence Interval (0.74, 6.73)] and, particularly, saturated fat [OR = 4.32, 95% CI(1.39,13.7)]. Although dietary cholesterol intake appeared to increase risk and a number of many micro-nutrients were apparently associated with reductions of risk, none were statistically significant. The results are consistent with a role of nutritional factors in the etiology of pancreatic cancer. The magnitude of the risks involved emphasizes the necessity for larger studies of this topic.

[Predictive value of preoperative acidity tests in ulcer recurrence after supraselective vagotomy].

The authors have analysed the predictive value of the basal and peak gastric acidity levels, measured preoperatively, in a series of 27 supraselective vagotomies. They recommend care in the choice of this operation for hypersecretors and they propose criteria for the preoperative selection of the candidates. They suggest determination of the preoperative basal gastric acidity level and a cimetidine suppression test to identify patients at high risk for recurrence of the ulcer.

Gastro-cutaneous syndrome: peptic ulcer/hiatal hernia, multiple lentigines/café-au-lait spots, hypertelorism, and myopia.

We report the familial occurrence in a French Canadian family of peptic ulcer/hiatal hernia, multiple lentigines/café-au-lait spots, apparent hypertelorism, and myopia caused by a pleiotropic autosomal dominant gene with high penetrance and variable expressivity. Other probable but rarer components of the syndrome include ischemic heart disease, congenital heart disease, and maturity onset diabetes. Symptoms of peptic ulcer/hiatal hernia usually started in the second or third decade and were associated, as least in some examined individuals, with relatively increased acid secretion and abnormal dermatoglyphics.

An unusual beta-cell adenoma.

An unusual case of insulinoma in a 51-year-old man demonstrates the difficulties in diagnosing and treating hypoglycemia. From the many laboratory tests and procedures performed, the only findings typical of insulinoma were inappropriate values of plasma immunoreactive insulin in relation to the corresponding values of blood glucose, and these were sporadic. A small beta-cell adenoma in the pancreatic head was the cause of the hypoglycemia.
