Laboratory examination revealed the following: hematology: pancytopenia (WBC 2,900/μL, RBC 335 × 104/μL, Hb 10.2 g/dL, Plt 10.1 × 104/μL); blood biochemistry: slight deterioration of liver function and electrolyte abnormalities (AST 37 U/L, ALT 30 U/L, LDH 250 U/L, ALP 454 U/L, γ-GTP 214 U/L, Na 132 mmol/L, Cl 95 mmol/L), and significant increase in serum CRP (CRP 32.76 mg/dL); blood coagulation profile: elevation of serum levels of FDP (FDP 22.5 μg/mL); serum tumor marker levels: within normal range. Here, CRP is linked to neoplasm.
