A mild elevation of both glycoantigen ca242 and CA72-4 is considered a benign lesion of the gastrointestinal tract or reproductive system, and a significant elevation may be a gastrointestinal tumor or ovarian cancer, or a recurrence of a previous tumor.
The glycoantigens ca242 and CA72-4 are tumor markers commonly used in clinical physical examinations, with ca242 overexpressed in patients with pancreatic and colon cancer and the glycoantigens ca72-4 important for the diagnosis of gastric and ovarian cancer.
Tumor markers are one of the mandatory items in physical examinations for middle-aged and elderly people. If the results of blood tests taken during physical examinations reveal: mild elevation of glycoconjugate antigen ca242 and/or CA72-4, it suggests possible lesions of the digestive tract or reproductive system, which are mostly benign diseases at this time, such as ulcerative colitis, colon polyps, ovarian cysts, etc.; if the two tumor markers are significantly elevated, more than 5 times higher than the normal reference range If the two tumor markers are significantly elevated, more than 5 times higher than the normal reference range, the first consideration is gastrointestinal tumor, such as colon cancer, gastric cancer, etc., which needs to be combined with the patient’s clinical symptoms and further pathological biopsy to clarify the condition and guide the subsequent surgical treatment and chemotherapy plan formulation. For patients with a history of malignancy, a significant increase in both tumor markers at the time of review suggests tumor recurrence.
