Mean Platelet Volume as a Prognostic Marker in Metastatic Colorectal Cancer Patients Treated with Bevacizumab-Combined Chemotherapy

Abstract

The MPV was significantly higher in the patients with mCRC compared to those with non-mCRC (7.895±1.060 versus 7.322±1.136, p=0.013). The benefit of bevacizumab on PFS was significantly greater among the patients with low MPV than those with high MPV. The hazard ratio (HR) of disease progression was 0.41 (95%CI, 0.174-0.986; p=0.04). In conclusion, despite the retrospective design and small sample size, MPV can be considered a prognostic factor for mCRC patients treated with bevacizumab-combined chemotherapy.
