Primary Outcome Measures

Name	Time	Method
Main Objective: To evaluate the changes in molecular pathways of cell adhesion (E-cadherin and ß-catenin cellular localization) in colon polyps prior to and after treatment with mesalazine (5-ASA);Secondary Objective: To examine the changes in related chemopreventive pathways<br>(Rac1/PAK-1, PI3K/Akt, ras/raf) in colon polyps prior to and after treatment with mesalazine;Primary end point(s): Increase of the immune reactivity score of membranous E-cadherin in epithelial cells of the polyps before and after mesalazine treatment;Timepoint(s) of evaluation of this end point: Prior to treatment and after 14 days of treatment

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): - Increase of the immune reactivity score of membranous E-cadherin in the normal mucosa before and after mesalazine treatment<br>- Change in the immune reactivity score of membranous ß-catenin in the polyps and in the normal mucosa before and after mesalazine treatment<br>- Changes in related chemopreventive pathways (Rac1/PAK-1, PI3K/Akt, ras/raf) in the polyps and in the normal mucosa prior to and after treatment with mesalazine<br>;Timepoint(s) of evaluation of this end point: Prior to treatment and after 14 days of treatment
