Growth rate of colon polyps and cancer.

Malignancy potential of colorectal polyps increases with size. The growth rate and destiny of each polyp is virtually unknown. It was recently shown that polyps smaller than 10 mm left in situ may partly regress or partly increase in size, whereas one quarter of polyps are unchanged after 3 years. Polyps smaller than 5 mm show a mean increase in size, whereas polyps measuring 5 to 9 mm show a mean decrease in size. Methodologic problems with the measurement of polyps and cancer are discussed. More studies of polyp growth related to risk factors are warranted.

Proliferative activity of rectal mucosa and soluble fecal bile acids in patients with normal colons and in patients with colonic polyps or cancer.

Rectal biopsies and fecal collections were obtained from a consecutive series of 34 outpatients prior to colonoscopy at a gastroenterology clinic. Subsequently, 14 were found to have no colonic pathology, 13 had adenomatous polyps, (3 of those had a previous history of colon cancer) and 7 were diagnosed with colon cancer. In confirmation of earlier studies the tritiated thymidine labelling index was higher in patients with tumors than in those without pathology (7.9% vs. 5.8% with P = 0.06). The patients with colonic tumors also had significantly higher levels of deoxycholic acid (P = 0.01) and lithocholic acid (P = 0.005) in the aqueous extract of their feces. This study shows that these biochemical measures may indicate colon cancer risk.
