CEACAM4 and neoplasm: In addition, CEACAM4 and HAMP were revealed to express differently across T stage (p‐value; CEACAM4: 1.47e−06; HAMP: 8.02e−08), N stage (p‐value; CEACAM4: 2.34e−06; HAMP: 6.41e−10), M stage (p‐value; CEACAM4: 5.52e−04; HAMP: 9.69e−05), tumor stage (p‐value; CEACAM4: 3.06e−05; HAMP: 4.71e−07), and tumor grade (p‐value; CEACAM4: 3.92e−05; HAMP: 1.58e−06) (Figure 6B).
