Abstract:

Objective

To investigate the diagnostic performance of ten serum markers of AFP, CEA, CA199, CA724, CA125, CA50, CA242 and PGⅠ, PGⅡ and PGR (PGⅠ/PGⅡ) in gastric cancer.

Methods

67 cases of gastric cancer patients in our hospital from August 2018 to February 2019 were selected as gastric cancer patients. All of the included cases were diagnosed with gastric cancer by gastroscopy and pathological tissue. According to whether sub-abdominal radical resection was performed, it was divided into 30 cases in the preoperative subgroup of gastric cancer and 37 cases in the postoperative subgroup of gastric cancer. In the same period, 30 cases with benign gastric disease were selected as gastritis group, and 20 cases of healthy physical examination were selected as healthy control group. AFP, CEA, CA199, CA724, CA125, CA50, CA242, PGⅠ, PGⅡ and PGR were detected, and the application value of these indicators in the diagnosis and treatment of gastric cancer.

Results

The concentration levels of CEA, CA199, CA724, CA125 and CA242 in the preoperative subgroup of gastric cancer were higher than those in healthy control group, gastritis group and postoperative gastric cancer subgroup (P<0.05), and the levels of PGⅠ, PGⅡ and PGR were lower than those in the healthy control group and the gastritis group, the levels of PGⅠ, PGⅡ were higher than the postoperative subgroup of gastric cancer (P<0.05). The levels of PGI and PGII in the postoperative subgroup of gastric cancer were lower than those in the healthy control group. The results of ROC curve analysis showed that the area under the combined diagnostic curves of PGⅠ, PGⅡ and PGR was 0.759. The area under the combined diagnostic curve of ten serum markers was 0.871.

Conclusions

CEA, CA199, CA724, CA125, CA242, PGⅠ, PGⅡ, PGR have certain clinical value in the diagnosis of gastric cancer and the differential diagnosis of benign and malignant tumors. PGⅠ, PGⅡ, PGR tests are useful for assessing and monitoring gastric mucosal function, The combination of PGⅠ, PGⅡ, PGR and ten serum markers have good diagnostic performance for the diagnosis of gastric cancer.
