癌抗原72-4 CA72-4
Cancer Antigen 72-4 (CA 72-4): Tumor Marke
*CA 72-4 is a tumor-associated glycoprotein that is primarily used for the diagnosis and monitoring of gastric cancer, ovarian cancer, and other certain cancers. It is usually secreted during the tumor cell proliferation process, and its levels may rise significantly in some cancer patients.
*Normal Range: < 6.9 U/mL (the range may vary depending on the testing method)
*Causes of Elevated CA 72-4
-Gastric Cancer:
CA 72-4 is sensitive for gastric cancer and is an important marker for diagnosing and monitoring treatment, especially in advanced gastric cancer.
-Ovarian Cancer:
In mucinous ovarian adenocarcinoma, CA 72-4 levels may rise significantly, and it can assist in diagnosis and monitoring.
-Other Cancers:
CA 72-4 may also be elevated in other cancers, including colon cancer, breast cancer, pancreatic cancer, and lung cancer.
-Benign Diseases:
In certain non-cancerous conditions (e.g., liver cirrhosis, gastrointestinal inflammation, or ovarian cysts), CA 72-4 levels may be mildly elevated.
*Uses
-Diagnostic Aid:
Although CA 72-4 has relatively high sensitivity for some cancers, it is not sufficient for cancer diagnosis on its own. It should be used in conjunction with imaging tests and other tumor markers (e.g., CEA, CA 19-9).
-Monitoring Treatment:
In patients already diagnosed with gastric cancer or ovarian cancer, changes in CA 72-4 levels can reflect the effectiveness of treatment. If treatment is effective, CA 72-4 levels typically decrease.
-Detecting Cancer Recurrence:
Regular monitoring of CA 72-4 helps in the early detection of cancer recurrence.
*Health Recommendations
-Further Investigation:
If CA 72-4 levels are elevated, further imaging studies (e.g., gastroscopy, CT scan) or pathological examination are necessary to confirm the tumor's nature and origin.
-Screening for High-Risk Populations:
For individuals with a family history of gastric cancer or ovarian cancer, regular CA 72-4 testing may help in the early detection of these cancers.
*Conclusion
CA 72-4 is an important tumor marker for diagnosing and monitoring gastric and ovarian cancers, among others. However, it is not specific enough for a definitive diagnosis and should be combined with other tests for a comprehensive evaluation. Regular monitoring can also assist in detecting cancer recurrence or assessing treatment response.
