Abstract:
Objective:To comprehensively analyze the clinical values of serum tumor markers of colon cancer, including carbohydrate antigen 724 (CA724), cytokeratin 19 fragment antigen (CYFRA21-1), carbohydrate antigen199 (CA199) and carcinoembryonic antigen (CEA) in the diagnosis and prognosis prediction of colon cancer in patients.Methods:The clinical data of 160 patients with colon cancer who received treatment in Zhuji Central Hospital from January 2018 to December 2020 (observation group) and the clinical data of 156 patients with benign colon polyps who concurrently received physical examination (control group) were retrospectively analyzed. All patients underwent CA724, CYFRA21-1, CA199 and CEA tumor marker screening. The levels of tumor markers, the positive rate of a single tumor marker, and the positive rate of a combination of four markers were compared between the control and observation groups. The levels of tumor markers were compared among different pathological stages. The levels of serum tumor markers were compared among patients with different prognoses based on 1-year follow-up data.Results:CA199-positve rate, CEA-positive rate, CYFRA21-1-positve rate, CA724-positive rate, and the positive rate of a combination of four tumor markers were 85.63% (137/160), 86.88% (139/160), 71.88% (115/160), 85.00% (136/160), and 95.63%(153/160), respectively, which were significantly higher than those in the control group ( χ2 = 8.64, 10.28, 8.33, 9.93, 7.27, all P < 0.001). Serum CA199, CEA, CYFRA21-1 and CA724 levels in patients with stage III-IV colon cancer were (58.96 ± 13.59) U/mL, (38.69 ± 11.84) μg/L, (14.78 ± 3.68) μg/L, (23.68 ± 5.38) U/mL, respectively, which were significantly higher than those in patients with stage I-II colon cancer [(48.35 ± 9.03) U/mL, (23.96 ± 12.25) μg/L, (9.57 ± 2.53) μg/L, (13.02 ± 4.32) U/mL, t = 10.29, 12.02, 8.47, 10.54, all P < 0.001). One-year follow-up results showed that serum levels of CA199, CEA, CYFRA21-1, CA724 in patients with recurrence and metastasis of colon cancer were (38.68 ± 3.04) U/mL, (17.12 ± 4.96) μg/L, (8.94 ± 2.32) μg/L, (11.22 ± 1.94) U/mL, which were significantly higher than those in patients without recurrence of colon cancer [(30.02 ± 2.95) U/mL, (3.75 ± 1.06) μg/L, (3.06 ± 1.15) μg/L, (6.28 ± 1.53) U/mL, t = 8.73, 11.02, 7.72, 7.57, all P < 0.001]. Conclusion:Serum levels of CEA, CA199, CA724 and CYFRA21-1 can be used as important indicators for diagnosis and prognosis prediction of colon cancer.
