Abstrakt: | Introduction: The transcriptional activity of the UGT1A1 gene is modulated by a variable number of repetitions of the dinucleotide (TA) within its promoter region. By comparison to the most common allele (TA) Material and Methods: All patients treated for colorectal cancer in a tertiary care centre, between January 2009 and December 2013, who had routine UGT1A1 genotyping for irinotecan dose-adjustment were included. Data were retrospectively collected. Results: 292 patients were enrolled, including 23 UGT1A1*28/*28 homozygous (7.9%), 137 wild type homozygous (46.9%) and 132 heterozygous (45.2%). There were no significant differences in phenotypic colonic characteristics between homozygous and heterozygous patients carrying the UGT1A1*28 allele as compared to *1/*1 homozygous. Patients treated with aspirin were significantly more common in the UGT1A1*28/*28 homozygous group than in the other groups (7/23 (30.4%) compared to 22/269 (8.2%), p = 0.001). Conclusion: Dinucleotide polymorphism in the promoter region of the UGT1A1 gene is not associated with a specific colonic phenotype in patients with sporadic colorectal cancer.
