The test is intended for use as an aid in monitoring patients previously treated for Stage II or Stage Ill breast cancer. Serial testing for CA 27.29 in the serum of patients who are clinically free of disease should be used in conjunction with other clinical methods used for the early detection of cancer recurrence. The test is also intended for use as an aid in the management of breast cancer patients with metastatic disease by monitoring the progression or regression of disease in response to treatment.",
