Tumor markers in the early detection of tumor recurrence in breast cancer patients: CA 125, CYFRA 21-1, HER2 shed antigen, LDH and CRP in combination with CEA and CA 15-3

摘要

Background: Kinetics of CA 15-3 and CEA have a high specificity in the early detection of metastatic breast cancer (MBC). However, this high specificity is associated with a lack of sensitivity. To decrease the number of false negative patients, the additional diagnostic potential of an extended panel of biomarkers was evaluated.
