In the comparison with CEA (Table 2), DA-HNRNPA1 was not different from DA-CEA in both low- and high-stage gastric adenocarcinoma, whereas in CRC, DA-HNRNPA1 was not different from DA-CEA in low-stage CR-adenocarcinoma, but it was significantly lower than DA-CEA in high-stage CR-adenocarcinoma. The gene discussed is HNRNPA1; the disease is adenocarcinoma.
