CEACAM5 and neoplasm: We obtained an candidate subset of 6 clinical features (age, M stage, preoperative CA19-9 level, preoperative CEA level, pathological grading and tumor size), 3 primary lesion radiomics features (Lesion_glcm_ldmn, Lesion_glszm_ZonePercentage, and Lesion_glszm_LowGrayLevelZoneEmphases) and 3 peripheral LN radiomics features (Lymph_glrlm_GrayLevelNonUniformity, and Lymph_firstorder_Kurtosis, Lymph_gldm_GrayLevelNonUniformity) (Fig. 2).
