Is Change in Hemoglobin Level a Predictive Biomarker of Tyrosine Kinase Efficacy in Metastatic Renal Cell Carcinoma? A Turkish Oncology Group Study

Cancer Invest. 2017 Apr 21;35(4):248-255. doi: 10.1080/07357907.2017.1292518. Epub 2017 Mar 23.

Abstract

Background: There are insufficient predictive markers for renal cell carcinoma (RCC).

Methods: A total of 308 metastatic RCC patients were analyzed retrospectively.

Results: The increased hemoglobin (Hb) group had significantly higher progression-free survival and overall survival (OS) compared with the decreased Hb group at 11.5 versus 6.35 months (p < .001) and 21.0 versus 11.36 months (p < .001) respectively. The 1- and 3-year OS rates were higher in the Hb increased group, i.e., 84% versus 64% and 52% versus 35% respectively.

Conclusions: The present study showed that increased Hb levels after tyrosine kinase inhibitor therapy could be a predictive marker of RCC.

Keywords: Hemoglobin; predictive; renal cell carcinoma; survival; tyrosine kinase inhibitor.
