What is Tumor Markers

• Definition
• A tumor marker is a biomarker found in blood,
  urine, or body tissues that can be elevated by
  the presence of one or more types of cancer.
  There are many different tumor markers, each
  indicative of a particular disease process, and
  they are used in oncology to help detect the
  presence of cancer.

3

• A tumor marker is a substance that is produced by
  the body in response to cancer, or is produced by
  the cancer itself.
• Some of these markers are specific to one cancer,
  while others are seen in several types of cancer.
  
• These markers are generally used to evaluate the
  patient's response to treatment or to monitor for
  recurrence (return of the cancer after
  treatment).
• There are non-cancerous conditions that can cause
  markers to be elevated, so these must also be
  considered when interpreting the test results.

Common Tumor Markers

• CA15-3 is a sensitive tumor marker for breast
  cancer.
• CA19-9 antigen has been shown to be elevated in
  the blood of some patients with gastrointestinal
  tumors.
• CA-125 is a useful marker for monitoring disease
  progression in ovarian cancers.
• PSA is a useful marker for monitoring disease
  progression in prostate cancers.
• CEA (carcinoembryonic antigen) is useful in
  monitoring patients with various types of
  malignancies, such as gastrointestinal,
  pancreatic, breast, and lung cancers.

Uses

• Tumor markers can be used in conjunction with
  other tests (scans, biopsies, etc.) to help
  diagnose a patient who has symptoms suspicious
  for cancer.
• Some markers can help physicians to determine
  prognosis and treatment.
• Markers could be used as a screening tool for the
  general public. The goal of a screening test is
  to diagnose cancer early, when it is the most
  treatable and before it has had a chance to grow
  and spread.
