CRP and Sepsis: In the absence of sepsis, PCT levels of patients with metastatic tumor were significantly higher than those without metastasis, in contrast with CRP or leukocyte, where the increases in those markers were not statistically significant [13.6 mg/L (0.8–210.5) vs. 5.8 mg/L (0.5–209.8), p = 0.370, and 8860/μL (2930–24,910) vs. 7730/μL (1100–22,680), p = 0.629], respectively.
