Core Tip
Core tip: In the future, the 7-gene (CPEB4, EIF2S3, MGC20553, MS4A1, ANXA3, TNFAIP6 and IL2RB) logistic regression model that showed the best results can be further verified for more samples. Meanwhile, the causal relations are needed to confirm among the selected genes and colorectal cancer (CRC). The expression signature of these CRC-associated genes can be evaluated for early detection of CRC. Early detection can thus improve survival in patients before symptoms are detectable, during treatment, or during remission.
