title: [Family anamnesis, cholecystectomy and gastric resection in patients with colorectal carcinoma: a case-control study].
abstract: An increased risk of colorectal cancer has been reported in first-degree relatives of affected patients, and following cholecystectomy or partial gastrectomy for benign peptic ulcer disease. The aim of this study was to examine the incidence of these potential risk factors in 197 patients (127 males, 70 females, mean age 70 years +/- 10.9, range 22-94 years) with cancer of the large bowel and 202 controls (91 males, 111 females, mean age 68 years +/- 14.06, range 17-93 years) who underwent a total colonoscopy, that revealed no colorectal neoplasms. No significant differences were found between the case and control group for a past history of cholecystectomy or gastric surgery, respectively reported by 14 and 12 patients of group 1 and 18 and 8 patients of group 2. Patients with large bowel cancer show a significant excess of both colorectal (21.31% vs 11.9%) and extracolonic malignancies (46.19% vs 26.73) in first degree relatives (p < 0.05). In approximately 7% of them the aggregation of two or more colorectal cancers among relatives is suggestive for a hereditary form of large bowel cancer.
