CEACAM5 and colorectal carcinoma: In the meantime, multivariate analysis identified that high IMFA (Male ≥ 14.39 cm2, Female ≥ 27.78 cm2) (HR = 1.769, 95% CI 1.049–2.983, p = 0.033) and high CEA level (HR = 2.207, 95% CI 1.217–4.000, p = 0.009) were independent prognostic factors for poor DFS in CRC patients in the training set (Table 3).
