Problem: The pathogenesis of colorectal cancer must be perceived as a complex interaction between the genetic make-up of the individual and the environment. Recent publications stress the association between colorectal carcinoma and cholelithiasis.
Objective: A retrospective study was set up to compare the presence of cholelithiasis/cholecystectomy in patients with colorectal carcinoma vs gastric carcinoma.
Patients: In 481 patients with colorectal carcinoma, and in another group of 126 patients with gastric carcinoma, the incidence of prior cholelithiasis/cholecystectomy was investigated.
Results: In the colorectal carcinoma cases a personal history the cholelithiasis was observed more often than cholecystectomy, 88 vs 8 (P < 0.001) patients, and cholelithiasis was more commonly observed in cases of right-sided colonic cancer, than in cancer of the left colon and rectum. In the group with gastric carcinoma the cholelithiasis incidence was 5.6 percent.
Conclusions: These findings suggest that a relationship was found more often between colorectal cancer and cholelithiasis, that with cholecystectomy.
