Sitzende Tätigkeit und Rektum-Sigma-Karzinom

Abstract

Whether there is a relationship between sedentary occupation and the occurrence of rectal and sigmoid cancer was studied. Patients (105) with histologically proven rectal cancer were questioned; patients (55) with gastric carcinoma and 99 patients with cholelithiasis served as control groups. The percentage of patients with a sedentary occupation is significantly higher in the group with rectal cancer. The mean duration of the sedentary occupation is also longer. A direct relationship between the sedentary occupation and the tumor stage is obvious. A sedentary occupation-which leads to changes in the motility of the large bowel-is a risk factor in the occurrence of rectal and sigmoid cancer.
