摘要
The aim of the present study was to investigate the association between serum carbohydrate antigen (CA)19-9 and CA125 levels, and human epidermal growth factor receptor 2 (HER2) expression in patients with gastric cancer, as well as to identify any correlation between them and the risk of recurrence and metastasis. A total of 256 patients were enrolled in the present study, and 219 patients were followed-up to investigate recurrence and metastasis of gastric cancer. Immunohistochemistry was used to detect HER-2 in gastric adenocarcinoma and paracancerous tissues. The positive rate of CA19-9 and CA125 in stages III/IV was higher compared with that in stages I/II. The positive rate of HER2 in distinct stages of gastric cancer was not statistically different. Serum CA19-9 and CA125 were not associated with the positive expression of HER2. The recurrence and metastasis of CA 19-9, CA125 and HER2-positive gastric cancer were increased compared with those experienced by CA19-9, CA125 and HER2-negative patients. Age, stage and preoperative tumor markers were associated with 3-year prognosis of gastric cancer. HER2 [odds ratio (OR)=2.55] and CA19-9 (OR=1.22) were independent prognostic factors in patients with gastric cancer. CA19-9, CA125 and HER2 may be used to predict the recurrence or metastasis of gastric cancer. The combined detection may be able to improve the sensitivity and efficiency of predicting the recurrence or metastasis of gastric cancer. Preoperative positive serum for CA19-9 and CA125 were associated with poor prognosis in patients with gastric cancer. CA19-9 and HER2 were independent prognostic factors of gastric cancer.
