While routine blood tests did not reveal major abnormalities, targeted investigations based on clinical and radiological findings demonstrated markedly elevated serum tumor markers: β-hCG at 332,456 mIU/mL, alpha-fetoprotein (AFP) <1 ng/mL, and lactate dehydrogenase (LDH) at 742 U/L (Table 1). This evidence concerns the gene AFP and neoplasm.
