CA 72.4

The test is a blood test used to measure the level of cancer antigen 72.4, a tumor marker often associated with gastric (stomach) cancer and certain other gastrointestinal cancers. It is mainly used to monitor treatment response and detect recurrence in patients already diagnosed with cancer.

The purpose of this test is to:

• Measure CA 72.4 levels in the blood
• Monitor gastric (stomach) cancer and other GI cancers
• Evaluate treatment response
• Detect recurrence of cancer
• Support diagnosis along with other medical tests

CA 72.4 Test Purpose

The CA 72-4 (Cancer Antigen 72-4) Test measures the level of CA 72-4, a tumor marker found in the blood that may be elevated in certain types of cancer, particularly gastric (stomach) cancer. The test is primarily used to monitor treatment response, assess disease progression, and detect cancer recurrence rather than to diagnose cancer on its own.

Healthcare providers commonly recommend the CA 72-4 Test for individuals who have been diagnosed with stomach cancer or who are undergoing treatment for gastrointestinal cancers. It may also be useful for patients with symptoms such as persistent abdominal pain, unexplained weight loss, loss of appetite, difficulty swallowing, nausea, vomiting, early satiety, or gastrointestinal bleeding, especially when cancer is suspected based on clinical findings or imaging studies.

Furthermore, elevated CA 72-4 levels may also be seen in ovarian cancer, particularly mucinous ovarian tumors, and less commonly in colorectal, pancreatic, esophageal, and other gastrointestinal cancers. However, increased CA 72-4 levels can also occur in certain non-cancerous conditions, including gastritis, peptic ulcers, liver disease, pancreatitis, and other inflammatory gastrointestinal disorders.

The CA 72-4 Test is often performed alongside CEA (Carcinoembryonic Antigen), CA 19-9, CA 125, Upper Gastrointestinal Endoscopy, CT Scan, MRI, and biopsy findings to provide a comprehensive evaluation of gastric and ovarian cancers.

CA 72.4 Test is Recommended for Individuals:

• Patients diagnosed with stomach (gastric) cancer.
• Individuals undergoing treatment for gastric or gastrointestinal cancers.
• Patients requiring monitoring for cancer recurrence.
• Individuals with suspected ovarian cancer, especially mucinous ovarian tumors.
• People with persistent abdominal pain, unexplained weight loss, or loss of appetite.
• Patients advised by their oncologist to undergo tumor marker testing.
• Individuals requiring ongoing monitoring of cancer treatment response.

FAQs

1. What is the CA 72-4 Test used for?

The CA 72-4 Test measures the level of Cancer Antigen 72-4 in the blood. It is primarily used to monitor stomach (gastric) cancer, evaluate treatment response, detect recurrence, and support the assessment of certain ovarian and gastrointestinal cancers.

2. Do I need to fast before the CA 72-4 Test?

No. Fasting is generally not required for the CA 72-4 Test. However, always follow any preparation instructions provided by your healthcare provider before sample collection.

3. Does a high CA 72-4 level always mean cancer?

No. An elevated CA 72-4 level does not always indicate cancer. It may also occur in gastritis, peptic ulcers, liver disease, pancreatitis, and other benign gastrointestinal conditions. Your healthcare provider will interpret the results together with your symptoms, imaging studies, medical history, and additional laboratory tests to determine the underlying cause.
