Moreover, the median survival time (MST) was statistically significant between the different expression of the three tumor markers (25.03 months versus 18.90 months, p<0.001 for CEA; 24.47 months versus 16.30 months p<0.001 for CA19-9 and 24.97 versus 17.67 months, p<0.001 for CA72-4). The gene discussed is CEACAM5; the disease is neoplasm.
