[Diet and rectocolonic cancers. Results of a case-control study].
In a case-control study performed in an hospital of the North-Eastern Paris area, nutritional intakes of 94 patients with colorectal carcinoma were compared with those of 94 control patients, matched for age and sex. Results were expressed as mean daily nutrients and energy intakes. This dietary survey covered the "present period" (i.e. prior to the hospitalisation) and the "past-period" in case of striking and prolonged changes in dietary habits. Whatever the site of carcinoma (the rectum and sigmoid or the remaining colon) there was no statistically significant difference between patients and controls (in both sexes) for the following parameters: a) total energy intake, b) proportions of lipids, proteins and fat expressed as percentages of total energy intake, c) minerals, d) vitamins and e) dietary fibers. In women with colorectal carcinoma, a decrease in alcohol and lipid consumptions was observed. In patients with rectal or sigmoid carcinoma past alcoholic intakes were higher in both sexes. These results do not allow any clear epidemiological conclusion. In spite of their cost and length prospective studies are probably the only way to answer the difficult question of which dietary factors may be found in colorectal carcinoma.
