Many studies incorporated clinical features such as patient demographics (e.g., age, gender, and race), tumor characteristics (e.g., size, location, and stage), and biomarkers like Cancer Embryonic Antigen (CEA) and Carbohydrate Antigen (CA19-9) levels [5,11,24,29,30,32,33,37,38,42,43]. Here, CEACAM5 is linked to neoplasm.
