Screening of tumoral markers showed an elevated cancer antigen 19-9 (CA19-9) (171 U/mL (normal range: <35.0 U/mL)) and carcinoembryonic antigen (CEA) (7.23 ng/mL (normal range: <3.00 ng/mL)), but chromogranin A (CgA) was within normal range (20 ng/mL (normal range: 11.80–88.00 ng/mL)). This evidence concerns the gene CEACAM5 and cancer.
