We performed a relaxed lasso model building procedure using standard laboratory data derived from a routine clinical setting (albumin, erythrocyte, platelet and leucocyte count, hemoglobin, CRP, GGT, alkaline phosphatase (AP), LDH, and fibrinogen), common tumor markers (CA125, cancer Antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA)) and patients’ age at diagnosis. This evidence concerns the gene CEACAM5 and cancer.
