Recent international publications remark the association about carcinoma of the colon and cholelithiasis. These two entities with similar geographical distribution can be seen frequently in the modern western societies, being the cause as aetiological factors the low content in dietetics fiber. Different studies about the carcinoma of the colon and cholelithiasis pathogenesis had lead the possibility that the abnormal degradation of bile acids for the colonic bacterias, could be responsible of each one of these illness. The exposition of colonic mucosa to products of degradation of bile acids, specially secondary bile acids, may play a role in the etiopathogenic of colon carcinoma. It was analysed 135 patients with colon carcinoma or adenomatosis polyps, 42 with cholelithiasis or cholecystectomized for the same cause (31.1%), although in the control group, only 2(5%) had cholelithiasis. The female predominated the group of colon carcinoma and cholelithiasis, as well as cholecystectomized for that cause. The most frequent associated pathology was the diverticulosis.

In a retrospective study, the frequency of occurrence of gallstones and cholecystectomy in 479 patients with colorectal cancer was compared with that of 483 matched control patients with other malignancies. The mean interval between cholecystectomy and colon cancer diagnosis was 15.1 +/- 9.9 yr (range 2-53 yr), and there was no statistically significant difference, compared with the control group at 13.9 +/- 8.2 yr (range 2-31 yr). In patients with colon cancer, the general increased relative risk of concomitant diagnosed gallstones (relative risk 1.73, p = 0.0123) and the relative risk of cholecystectomy (relative risk 2.08, p = 0.0074) was statistically significant. However, when the data with regard to sex were analyzed, significant differences were observed only in women. Women affected by right colon cancer also had a statistically significant higher incidence of previous cholecystectomy (relative risk 2.86, p = 0.0096), but no significantly higher incidence of concomitant gallstones. The general increased relative risk in patients with right colon cancer and decreased risk in patients with left colon cancer of concomitant gallstones and prior cholecystectomy was statistically significant. Our data provide evidence for the hypothesis that both gallstones and cholecystectomy increase the general risk of large bowel cancer. Therefore, they are also compatible with the possibility that common risk factors causes the association between gallstones and large bowel cancer.

There are major differences in cholecystectomy rates between different countries. We prospectively recorded all gallbladder operations in L'Aquila, Italy (a small town in central Italy with a population of about 98,700 inhabitants) from June 15, 1987 to June 14, 1988. During that year 210 cholecystectomies were performed (women and girls = 71.4%), for a calculated yearly incidence rate of 0.212%. Cholecystectomy was elective in 85.2%, urgent in 8.6%, and was performed in the course of other abdominal operations (mainly colon cancer) in the remaining 6.2%. Half (44.3%) of the patients were operated on because of at least one episode of biliary colic, and 9.0% because of an acute complication. Respectively 16.2% and 30.5% were operated on because of dyspeptic symptoms or to prevent symptoms or complications. Gallstones were not found in six, while exploration of the common bile duct revealed gallstones in seven patients. The chemical analysis showed that 84.7% were cholesterol stones (mixed or pure). We presume that most observed differences in cholecystectomy rates between different Western countries are more likely owing to differences in indications for surgery rather than to differences in prevalence of gallstones.

The relationship between selected aspects of medical history and the risk of colorectal cancer was analysed using data from a case-control study of 673 cases of colon cancer, 405 of rectal cancer and 1501 controls in hospital for acute, non-neoplastic, non-digestive tract conditions, unrelated to known or suspected risk factor for large bowel cancer. Significantly elevated risks (RR) were observed for history of cholelithiasis (RR = 1.5 [95% confidence interval (CI) 1.1-2.1] for colon; 1.6 [1.2-6.4] for rectum) and diabetes (1.6 [1.1-2.3] for colon; 1.3 [0.8-2.0] for rectum), and a significant protection emerged for history of drug allergy (0.6 [0.4-0.9] for colon; 0.6 [0.5-1.0] for rectum). No significant association was found with thyroid disease, gastroduodenal ulcer, liver cirrhosis, hepatitis, pancreatitis, gastrectomy, appendicectomy, treatment with cimetidine/ranitidine, treatment with chenodesoxycholic acid or with blood transfusions. The associations with cholelithiasis, diabetes and drug allergy were not materially modified by allowance for major identified potential confounding factors, and were not restricted to the diseases diagnosed within 5 or 10 years before large bowel cancer diagnosis. Thus, the analysis of this large dataset offered further quantitative evidence suggesting a possible, however moderate, association between gallbladder disease and colorectal cancer risk, which may be related to enhanced or continuous secretion of secondary bile acids. The associations with diabetes and drug allergy were unexpected, and probably indirect, lacking previous epidemiological support or any obvious biological interpretation. Thus, they should be simply regarded as working hypotheses worthy of further consideration.

Evidence from case-control and cohort studies and animal research is reviewed to examine whether oral contraceptive (OC) use is related to cancer of the kidney, colon, rectum, gall bladder, extrahepatic bile ducts, benign or malignant pituitary tumors or prolactinemia. While animal research suggests possible hormone sensitivity, there are only 2 cohort studies available on renal adeno-carcinoma; result are contradictory. Colon and rectal cancer are sometimes studied separately and sometimes together despite different etiologic factors. Colon cancer is less common in women of higher parity, and associated with other female sex hormone related cancers. 3 case-control studies have produced no consistent results except for a possible higher risk of right colon cancer in OC users. Cohort studies on colorectal cancer resulted in very few cases and no significant increase in risk for these very common malignancies among OC users. Gallbladder cancer is associated with gallstones, a condition known to be enhanced by estrogens, yet 1 case-control study found no change in risk. In contract, cancer of the extrahepatic bile duct, usually more common in men, was found to be elevated in OC users in 1 small study. The question of pituitary tumors is complicated by difficulties in diagnosis, differentiating between hyperplasia, microadenomas, galactorrhea, prolactinemia and cycle irregularity. Basic research indicates that estrogens stimulate prolactin secretion and development of pituitary tumors. Yet of 6 case-control studies only 2 reported relative risks significantly above 1. Only 6 cases have been found in 3 large cohort studies. Therefore it is probable that any association of pituitary tumors with pills is largely due to their prescription for women with menstrual irregularity, some of whom had pre-existing pituitary adenomas.

Six cases of lung cancer combined with the disease which has needed semi-emergency operation, two cases of unstable angina, two of ileus due to colon cancer, one of impending rupture of abdominal aortic aneurysm and one of purulent cholecystitis with cholelithiasis, were discussed. Mean age was 62.0 years (range, 36 to 73); four were male and two were female. Case 1 and 2 were admitted with anterior chest pain, Case 3 with lumbago and abdominal pain, Case 4 and 5 with an abnormal shadow on chest x-ray film and Case 6 with abdominal pain. Of the two with unstable angina, one was operated on with right upper lobectomy during the first months after aorto-coronary bypass. Of the two with colon cancer, one was operated on with right upper lobectomy during about 5 weeks after right hemi-colectomy. Case 3 with abdominal aortic aneurysm operated on with left upper lobectomy during 4 weeks after replacement of abdominal aorta. Case 4 with cholecystitis was operated on with left pneumonectomy during about 3 weeks after cholecystectomy. The postoperative course of 4 cases and the post-chemotherapy condition of 2 cases were uneventful.

People who refuse to eat meat animal products mostly adhere to vegetarianism, veganism, crudivorism or macrobiotism, But these food habits are only one part of life-style chosen for spiritual, ethic or hygienic and healthy motivations. Except vitamin B12 deficiencies these regimens do not produce other deficiencies if they are correctly followed and if the energy intake is in agreement with the RDA'S. They reduce the risks of metabolic diseases, coronaropathies, arterial hypertension, colon cancer, diverticular disease of the colon, kidney and gallstones. Nevertheless crudivorism and macrobiotism are associated with high risks of deficiencies especially in children and pregnant women.

The authors draw attention to the high incidence of carcinoma of the large intestine in conjunction with cholecystectomy. The increased incidence of this disease was observed in patients after cholecystectomy (17.69%). The authors processed data from a group of 260 patients with colorectal carcinoma during the ten-year period from 1979 to 1988, in 46 with cholelithiasis during previous period cholecystectomy was performed, i.e. in 17.69%. It is assumed that the stimulating effect in carcinogenesis of the large intestine are changes in the bile acid metabolism occurring after cholecystectomy. Hitherto valid indications for cholecystectomy do not change, however, but make us consider these relationships in clinical practice and call for further analyses.

Our recent studies have shown a significant association between lithiasic biliary disease and colorectal cancer. This could be due to the existence of risk factors common to both disease or to a cause-effect correlation between them. This latter hypothesis is supported by the observation in gallstone patients of the increase of biliary and fecal concentrations in secondary biliary acids. These could have co-carcinogenic effect on the colon. With a view to singling out further elements which might help us to understand more clearly the possible cause-effect correlation between cholelithiasis and colon cancer, we examined 12 patients affected by both diseases. In these, we evaluated the composition of the gallbladder stones, by means of spectrophotometry and diffractometry. Bile samples were taken from the gallbladder and used to examine the lipidic composition and the cholesterol saturation index according to Carey. In addition bacteriological examinations were carried out. The results were compared with those of 10 patients with cholelithiasis but not cancer, 10 with cancer but not cholelithiasis and 10 with neither. Analysis of the results did not reveal significant differences in gallstone and bile composition between colon cancer patients with concomitant gallstones and control groups. However, in cancer patients with gallstones a higher incidence of bile bacteria (35.7%) was observed than in the other groups. Bile bacteria were observed more frequently in right colon cancer patients who had pigment stones in 75% of the cases. The results seem to evidence peculiarities in patients with a cancer of right colon.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of biliary deoxycholate as an endogenous colon carcinogen and the possible association between cholelithiasis and/or cholecystectomy and the subsequent development of large bowel cancer is unclear. This paper describes biliary bile acids analysis performed on 13 patients undergoing cholecystectomy for gall stones, 10 patients undergoing colonic resection for colon cancer, and eight control patients. For all 31 patients the total bile acids concentration was highly variable (8.3 mg/ml-106.5 mg/ml). The median ratio of primary to secondary bile acids was 2.7:1. The biliary bile acid ratios were similar in both control patients (3.7:1) and those with colon cancer (3.1:1), whereas patients with gall stones had significantly higher secondary bile acid levels in their biliary bile (ratio 1.9:1, p = less than 0.05). This result indicates that raised biliary deoxycholate concentrations are not present in patients with colon cancer and are therefore unlikely to be a major predisposing factor in the aetiology of this disease. It is unlikely that cholelithiasis and/or cholecystectomy predispose to the subsequent development of colon tumours.
