摘要: Background and aims The enzyme MTHFR plays an important role in folate metabolism, is implicated carcinogenesis due to its DNA methylation, repair, synthesis. We analyze the relationship of C677T A1298C polymorphisms with biological, clinicopathological, genetic epigenetic features tumors, patient outcome after treatment 5-FU-based chemotherapy determine contribution genotypes risk colorectal cancer (CRC) response therapy.
