Introduction Clear cell renal cell carcinoma is characterized by mutation or inactivation of Von Hippel-Lindau suppressor gene. The mutation of Von Hippel-Lindau mechanism is associated with the upregulation of the hypoxia-inducible factor protein, inducing the overexpression of proteins including erythropoietin and vascular endothelial growth factor. Vascular endothelial growth factor receptor-targeted tyrosine kinase inhibitors are widely used in treatment of metastatic renal cell carcinoma. In paradoxical hematological effect with tyrosine kinase inhibitor therapies, hemoglobin level may be increased, but polycythemia requiring phlebotomy is very rare. Case description We present here a case of renal cell carcinoma who received successive treatment with sunitinib, everolimus, and axitinib. While he had a normal hemoglobin level with prior sunitinib treatment, on the sixth week of axitinib treatment, he developed polycythemia and treatment response was seen after axitinib-associated polycythemia. Conclusion Progression-free survival (PFS) was 30 months in our case with third-line treatment axitinib. Higher hemoglobin levels may be associated with longer survival. Polycythemia was the first response to treatment of axitinib in our patient. It may be an indicator of persistent treatment response.

BACKGROUND: Clear cell renal cell carcinoma (CCRCC) is the most predominant renal tumour with unpredictable tumour behaviour. The aim of the study is to investigate the prognostic value of vascular endothelial growth factor A (VEGF-A) expression in CCRCC and to correlate it with other histological parameters as well as with patient's survival.MATERIAL AND METHODS: Tumour blocks were taken from 40 patients with histopathology diagnosis of CCRCC and tissue block from 20 normal kidneys as a control group were examined using the immuno-histochemical staining for VEGF-A.RESULTS: The VEGF A expression in CCRCC was significantly higher than in the normal kidney tissues (U’ = 720, P < 0.0001). VEGF A expression values in CCRCC were positively correlated with Disease Free Survival (r = 0.335, P = 0.034) and the tumor necrosis degree (r = 0.181, P = 0.262). VEGF-A expression values in CCRCC did not correlate with CD 31 expression (r = -0.09, P = 0.549), and Progression Free Survival (r = -0.07, P = 0.838). VEGF A expression values in CCRCC were negatively correlated with the tumor nuclear grade (r = -0.161, P = 0.318); the pathological tumor stage (r = -0.371, P = 0.018); the tumor size (r = -0.361, P = 0.022); the degree of tumor hemorrhage (r = -0.235, P = 0.143); and Cancer Specific Survival   (r = -0.207, P = 0.713).CONCLUSIONS: VEGF-A expression can be used to stratify advanced and metastatic CCRCC patients into low-benefit and high-benefit groups. Based on this study outcome it would be useful to perform IHC staining for VEGF-A expression in all patients with advanced and metastatic CCRCC.
