To help doctors provide their patients with the highest quality care, the American Society of Clinical Oncology ASCO developed a new guideline on using biomarkers to guide the treatment of metastatic breast cancer. A biomarker is a substance that is found in the blood, urine, or body tissues of a person with cancer.
A carcinoembryonic antigen CEA test is a blood test used to help diagnose and manage certain types of cancers. The CEA test is used especially for cancers of the large intestine and rectum. You doctor can also use the test results to help determine if a cancer treatment is working.
HealthCentral writers PJ and Phyllis were lifelines for me when my wife was going through treatment for stage I invasive breast cancer. She is doing great as a seven-year survivor. I remember learning that CEA levels can often fluctuate and be unreliable.
In order to better define clinical usefulness of CEA in breast cancer patients BCP we determined its baseline pre-treatment levels and correlated them with main parameters of primary tumor and metastases. The obtained results have been compared with those of two control groups: clinically healthy women, and patients with other types and locations of cancer. In both cancer groups the parameters of primary tumor size, grade and metastases time interval to metastases, location, size have been determined.
Breast cancer is the most frequent form of malignant cancer in women worldwide 1. While the primary tumor is often treatable, tumor recurrence remains the most frequent cause of breast cancer mortality. Thus, the treatment of metastatic disease is crucial for improving breast cancer survival 2.
Breast cancer is one of the most frequently occurring malignancies in China, with a steadily increasing incidence 1. Although the development of comprehensive therapy has reduced the mortality rate of breast cancer patients 2regional and distant recurrences remain a major threat to breast cancer patients 34. Serum tumor markers have been widely used as non-invasive tools for measuring treatment response, early diagnosis of recurrence and predicting prognosis.

Carcinoembryonic antigen CEA is a protein normally found in very low levels in the blood of adults. The CEA blood level may be increased in certain types of cancer and non-cancerous benign conditions. A CEA test is most commonly used for colorectal cancer. A CEA test may be done: if the doctor suspects there may be cancer to find out if cancer treatment is working to find out if cancer has come back recurred after treatment.
