Overview of Tumor Markers

Tumor markers are substances, often proteins, produced by cancer cells or by the body in response to cancer. They can be found in blood, urine, or tissues and are used to help diagnose cancer, monitor treatment, and check for recurrence. The presence of abnormal levels of these markers can indicate various malignancies or other health conditions.

Diagnostic Criteria for R97.8

1. Clinical Evaluation

• Patient History: A thorough medical history is crucial. This includes any previous cancer diagnoses, family history of cancer, and symptoms that may suggest malignancy (e.g., unexplained weight loss, fatigue, or pain).
• Physical Examination: A comprehensive physical examination may reveal signs that warrant further investigation, such as palpable masses or lymphadenopathy.

2. Laboratory Tests

• Blood Tests: Specific blood tests are conducted to measure levels of various tumor markers. Common markers include:
  • Alpha-fetoprotein (AFP): Elevated in liver cancer and germ cell tumors.
  • Cancer Antigen 125 (CA-125): Often elevated in ovarian cancer.
  • Cancer Antigen 19-9 (CA 19-9): Associated with pancreatic cancer.
• Immunoassays: Tests such as the immunoassay for tumor antigens (e.g., CA-125) are quantitative and help determine the levels of these markers in the blood[6][10].

3. Imaging Studies

• Imaging techniques such as ultrasound, CT scans, or MRIs may be employed to visualize potential tumors or abnormalities that correlate with elevated tumor markers.
