CEACAM5 and colorectal cancer: Increased LncRNA MIR4435-2HG expression in colorectal cancer was significantly associated with TNM stage (OR = 1.66 for T1/T2 vs. T3/T4, P = 0.015; OR = 1.68 for N0 vs. N1/N2, P = 0.002), stage (OR = 1.66 for stage1/2 vs. stage3/4, P = 0.003), and CEA level before treatment (OR = 1.70 for <5 vs. ≥5, P = 0.015) (Table 2).
