Combined use of tumor markers improves prognostic accuracy in gastric cancer

This study evaluated the combined use of three tumor markers (CEA, CA72-4, and CA19-9) for prognostic assessment in gastric cancer patients. Data from 1,966 patients who underwent curative gastrectomy were analyzed, and hazard ratios were calculated. The results showed that the combined use of tumor markers significantly improved prognostic accuracy compared to using a single marker. The survival prediction model incorporating the combined tumor markers proved accurate and effective, indicating its potential as a practical prognostic tool for clinicians.
