Tumor markers for gastric cancer include carcinoembryonic antigen, CA199, CA125, CA724, etc. It is recommended to consult a specialist.
Gastric cancer is a malignant tumor in the stomach. Tumor marker tests generally cannot diagnose gastric cancer, but can be used for follow-up and prognosis determination.
1. Carcinoembryonic antigen: Carcinoembryonic antigen has low specificity, it is elevated in some gastric cancer patients and can be decreased after the condition improves, it can evaluate the prognosis of gastric cancer and the effect of chemotherapy, it is often used for follow-up, but it is not recommended to be used for census and diagnosis in general.
2. CA199: It is an independent prognostic indicator for gastric cancer patients, and can determine the abdominal implantation and peritoneal recurrence of gastric cancer. With the combination of carcinoembryonic antigen and CA199, the diagnosis rate of gastric cancer can reach 85%.
3.CA125: some gastric cancer patients also have certain positivity.
4. CA724: combined with carcinoembryonic antigen, it can improve the sensitivity and specificity of gastric cancer diagnosis, but normal people can also be positive.
To diagnose gastric cancer, it is recommended to use endoscopy, imaging, histopathology and other examination methods to clarify.
If gastric cancer is suspected, it is recommended to diagnose it in a timely and correct way, and to diagnose and treat it in time.
