This study aimed to evaluate the usefulness of the C-C motif chemokine ligand 3 (CCL3) and C-C motif chemokine ligand 7 (CCL7) by assessing their serum concentrations in 40 patients with stage G1 + G2 and stage G3 + G4 renal cancer, as well as in 58 healthy volunteers. Here, CCL7 is linked to renal carcinoma.
