Abstract

The authors investigated the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in 101 metastatic colorectal cancer patients treated with 5-fluoropyrimidine-based therapy and in 196 healthy individuals by PCR-RFLP method. There was no significant difference in genotype distribution of patients and healthy controls, and between subgroups investigated according to clinical parameters (age, gender, tumor location, grade and treatment type). However, after a 3-30 (median 18.5) months follow-up the survival of patients with T allele proved to be better than that of patients with wild type (CC) genotype (p=0.036). In case of CT and TT genotypes the survival of patients receiving only first line therapy was significantly shorter than that of patients receiving more lines of treatment (p=0.015). Determination of MTHFR C677T polymorphism has prognostic value in case of patients with metastatic colorectal cancer receiving 5-fluoropyrimidine-based therapy, and may help in designing the individual (group) tailored therapy.
