The aim of this study was to compare carcinoembryonic antigen (CEA) and CA19-9 for the detection of local recurrences and distant metastases after complete resection of gastric carcinoma. At least one postoperative measurement of CEA and CA19-9 was performed in 54 patients. Among these, 32 had recurrence (59%) with a median follow-up of 618 days. Significantly higher sensitivity was observed for CA19-9 in comparison with CEA (68.8% vs 38.2% respectively), but specificity was slightly lower (81.8% vs 95.6% respectively). Increased CEA plasma level never preceded the diagnosis of recurrence while increasing CA19-9 preceded diagnosis in 13 patients (40.6%) from 1 to 22 months (median = 4.5 months). Increasing the normal range of CA19-9 to 80 UI/mL (2.5 x N) raises the specificity to 100% with acceptable sensitivity (53.1%). This study shows that CA19-9, compare with CEA, allows diagnosis of recurrence more often and earlier in the follow-up of resected gastric cancer.
