Based on univariable analysis results, clinical features with P < 0.10 (icterus, carcinoembryonic antigen (CEA), cancer antigen 199 (CA199), lesion size, cystic wall thickening, cystic wall enhancement, presence of septation, septation thickening, septation enhancement, and solid component) and the rescaled radiomic score were included in multivariable regression (Figure 2). Here, CEACAM5 is linked to cancer.
