Brief Summary:
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. .

Condition or disease Intervention/treatment Phase
Colorectal Cancer Drug: Mesalazine Phase 2

Detailed Description:
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.

Arm Intervention/treatment
Experimental: 5-ASA
Mesalazine 800 mg orally t.i.d for 3 months
Drug: Mesalazine
Mesalazine cpr 800 mg t.i.d. for 3 months
Other Names:
  • 5-aminosalicylic acid
  • 5-ASA
  • Pentacol

No Intervention: No treatment
no treatment

Primary Outcome Measures :
  1. Molecular analysis of gene expression levels of μ-protocadherin and other related proteins [ Time Frame: 3 months ]
    Molecular analysis (quantitative RT-PCR) of gene expression levels of μ-protocadherin, protocadherin 19, protocadherin 24, cadherin E, TCF7L2, TCF4, c-myc, Cyclin D1, p21waf1, VEGF, CD44, Met, KLF4 e CEBP-α and comparison of the levels assessed at the end of the treatment period with the baseline.

Secondary Outcome Measures :
  1. Evaluation of protein expression level of μ-protocadherin, Ki-67, Caspase-3 and Histone H2AXγ, evaluation of DNA oxidative damage and intra-mucosal concentration of 5-Acetylsalicylic acid [ Time Frame: 3 months ]

    These parameters will be examined using molecular analysis of the oxidation and depurination levels of the DNA and chromatographic analysis of the intra-mucosal concentration of 5-Acetylsalicylic acid, in biopsies of normal mucosa of the colon taken before and after the treatment of patients with 5-Acetylsalicylic acid:

    • quantification of the percentage of cells expressing the following proteins by immunohistochemical analysis: μ-protocadherin, Ki-67, Caspase-3 and Histone H2AXγ;
    • quantification of number of AP sites per 100000 DNA bp
    • quantification of nanograms di 8-OhdG (8-hydroxyguanine) per micrograms of DNA

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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

The following inclusion criteria was deleted according to Amendment n. 01 approved by the Ethical Committee on 19/dec/2014:

- 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
