The incidence of colonic polyps was reported to be increased in patients with Helicobacter pylori infection (Breuer-Katschinski et al, 1999) but any relationship between serum hyper-gastrinaemia and adenoma/polyp proliferation remains tenuous.
Previous studies have demonstrated that cyclin D1 is increased in adenomatous polyps and in both sporadic and familial forms of colorectal cancer (Motokura and Arnold, 1993; Bartkova et al, 1994; Arber et al, 1996, 1997).
Previous studies have demonstrated that cyclin D1 is increased in adenomatous polyps and in both sporadic and familial forms of CRC (Motokura and Arnold, 1993; Bartkova et al, 1994; Arber et al, 1996; Sutter et al, 1997).
While the underlying mechanism is not clear, the prevalence of gastric H. pylori infection was found to be increased, especially in colonic adenomas (71.4% in polyps, 55% in cancers) [ 21].
Increase in polyp size, advanced age and location in the distal colon were associated with presence of HGD/adenocarcinoma in large polyps, as identified by multivariate analysis.
There is increasing evidence that inorganic calcium-polyphosphates (polyP) are involved in human bone hydroxyapatite (HA) formation.
The numbers of colon polyps were significantly increased in adiponectin-deficient mice compared with wild-type mice fed a high-fat diet.
The expression of ribosomal protein S12 gene had been reported to increase in adenomatous polyps when compared to normal mucosa (Pogue-Geile et al, 1991).
In both genders there is a significant increase in polyp size detected during screening colonoscopy with increasing age.
In retrospect, it was realized that as he had grade 3 polyps at the start of challenge any response by increase in polyp size was difficult to appreciate and he was given an extra higher dose of lysine aspirin after he had begun to react.
