CRP and cancer: The patients with higher RDW values had more advanced cancer stages (p<0.0001), poorer PS (p<0.0001), higher WBC counts (p=0.006), lower hemoglobin levels (p<0.0001), lower MCV (p<0.0001), higher platelet counts (p=0.019), lower albumin levels (p<0.0001), higher CRP levels (p=0.002), and higher CYFRA levels (p=0.002).
