CRP and infection: The patient was afebrile; however, blood biochemical analysis revealed an elevated white blood cell (WBC) count of 17,000/μL (reference range: 4,000-11,000/μL) and a C-reactive protein (CRP) level of 7.53 mg/dL (reference range: <0.5 mg/dL), thus indicating an inflammatory response likely caused by infection at the extruded portion of the tumor.
