Only one article [48] reported the simultaneous measurement of four markers for lymph node metastasis, with reported sensitivities of 12.8%, 23.5%, 21.6%, and 15.7% for CA125 for CEA, CA19‐9, CA72‐4, and CA125, respectively. Here, CEACAM5 is linked to metastatic malignant neoplasm in the lymph nodes.
