CEA, CA19-9, and CA72-4 in Gastric Cancer Diagnosis and Progression: a Chinese Retrospective Case-Control Study

CEA, CA19-9, and CA72-4 were not applicable biomarkers for diagnosis, and the combination did not achieve better diagnosis efficiency. The levels of biomarkers cannot predict advanced GC, lymph node metastasis, and distant metastasis well. The measurements of biomarkers may not effectively identify recurrence after curative radical gastrectomy.
