MUC4 and colorectal carcinoma: Regarding relapse, the MUC4 rs2688513 GG genotype was associated with a high level of CRC relapse-free survival compared to the AA genotype and AA+AG model at both 3 years (GG genotype, adjusted HR = 2.894, 95% CI: 1.078–7.768, P = 0.036; recessive model, adjusted HR = 2.748, 95% CI: 1.059–7.130, P = 0.039) and 5 years (GG genotype, adjusted HR = 0.522, 95% CI: 1.068–7.671, P = 0.038; recessive model, adjusted HR = 2.737, 95% CI: 1.055–7.100, P = 0.040) (Fig 3, S5 and S7 Tables).
