The patients with higher RDW values had more advanced cancer stages (p=0.005), poorer PS (p=0.001), other diseases (p=0.006), higher WBC counts (p<0.001), lower hemoglobin levels (p<0.0001), lower MCV (p<0.001), higher platelet counts (p=0.045), lower albumin levels (p<0.0001), higher CRP levels (p<0.001), and higher cytokeratin 19 fragment (CYFRA) levels (p<0.001). Here, CRP is linked to cancer.
