Introduction: CA 15-3 and Carcino Embryonic Antigen (CEA) tumor markers play an important role in the early detection of metastasis and disease recurrence in breast cancer patients. The purpose of this study was to determine the relationship between increasing CA 15-3 and CEA marker values on histopathology grading, breast cancer metastasis, Disease-Free Survival (DFS), and Overall Survival (OS) in breast cancer patients.
Methods: This was an observational analytic study using a retrospective cohort design with a 36 months follow-up period.
Results: A total of 110 samples showed a significant relationship between the increased value of CA 15-3 and an increase in histopathology grading (p=0.032). However, there was no significant relationship between the increased value of CEA and an increase in histopathology grading (p=0.050). There were significant relationships between the increase in the value of CA 15-3 and CEA and the number of metastatic sites (p=0.002 and p=0.001). An increase in CA 15-3 was significantly associated with brain metastasis (p=0.004), while an increase in CEA was associated with liver and brain metastasis (p=0.012 and p=0.032). An increase in the value of CA 15-3 dan CEA also significantly reduced DFS and OS (p
