Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to obtain an "in vivo" confirmation that mesalazine induces the gene expression of μ-protocadherin and other related genes in the colon mucosa, as demonstrated in some "in vitro" experiments. .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pilot Trial, single-blind, parallel group on biopsy specimens of healthy colon mucosa in patients with precancerous lesions of the colon and rectum (adenomas) treated with mesalazine.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with precancerous colorectal lesions (polypoid or nonpolypoid adenomas) that needs of an endoscopic exam of control after 3 months from the removal of the lesions (determined on the basis of the morphological and histological characteristics of the lesions and of the removal technique)
* Ability and willingness to adhere to study regimen
* Written informed consent


\- diverticular disease/diverticular colitis;

The rationale of this change is that the presence of diverticular disease/diverticular colitis does not contribute to the definition of the trial primary end-points and represents a critical point during the patient selection with an impact on duration and conduction of the study.

Exclusion Criteria

* Patients under therapy with Aspirin (\>100 mg/die) or other FANS
* Inflammatory bowel disease (IBD)
* Hypersensitivity to Mesalazine.
* Pregnant or nursing (lactating) women
* Patients who belonging to the category n. 4 of the ASA physical status classification system
* contraindications to mesalazine therapy
