The study aimed to evaluate the effectiveness of two tumor markers, carcinoembryonic antigen (CEA) and CA19-9, in assessing disease stage in colorectal cancer patients.
A total of 155 patients' data from surgeries performed between 2015-2018 were analyzed, showing a significant correlation between CEA levels and disease stage, while CA19-9 showed no significant relationship.
The findings suggest that higher CEA levels are indicative of more advanced colorectal cancer, but neither marker was related to the tumor's anatomical location.
