Routine follow-up assessments, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 242 (CA242), and enhanced computed tomography (CT) scans of the chest, abdomen, and pelvis, indicated normal parameters with no signs of tumor recurrence. This evidence concerns the gene CEACAM5 and neoplasm.
