CRP and neoplasm: Advanced tumor status (p < 0.001), tumor stage (p < 0.001), skin invasion (p < 0.001), bone invasion (p < 0.001), and tumor depth ≥10 mm (p < 0.001) and advanced pathologic nodal status (p = 0.006) and lymphatic invasion (p = 0.068) were significantly correlated with CRP elevation (CRP ≥ 5.0 mg/L).
