The levels of tumor markers were as follows: lactate dehydrogenase (LDH) 182 U/L, ferritin (FER) 19.6 μg/L, human chorionic gonadotropin (HCG) < 0.5 IU/L, neuron-specific enolase (NSE) 18.7 ng/mL, alpha-fetoprotein (AFP) 6 ng/mL, carcinoembryonic antigen (CEA) 1.7 μg/L, cancer antigen 125 (CA 125) 13.5 kIU/L, cancer antigen 19-9 (CA 19-9) 11.6 kIU/L, and cancer antigen 15-3 (CA 15-3) 9.7 kIU/L. Here, ENO2 is linked to neoplasm.
