Tumour markers, such as serum alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), carcinoma antigen 125 (CA 125), neuron-specific enolase (NSE), and carbohydrate antigen 19-9 (CA 19-9), were examined because we also thought it might have been possible that the tumour did not originate from the adrenal gland. This evidence concerns the gene CEACAM5 and neoplasm.
