The significance of the C-reactive protein to albumin ratio as a marker for predicting survival and monitoring chemotherapeutic effectiveness in patients with unresectable metastatic colorectal cancer
Inflammation has been reported to play an important role in cancer progression and various inflammatory markers have been reported to be useful prognostic markers. The aim of this retrospective study was to evaluate the significance of the C-reactive protein to albumin (CRP/ALB) ratio in colorectal cancer patients who received palliative chemotherapy. We performed a retrospective review of 99 patients who underwent palliative chemotherapy for unresectable colorectal cancer between 2005 and 2010. The cutoff value of the CRP/ALB ratio was determined based on a receiver operating characteristics curve analysis. The relationship between the CRP/ALB ratio and survival was assessed. The cutoff value for the CRP/ALB ratio was 0.183. The high pretreatment CRP/ALB ratio group showed significantly worse overall survival. Patients with a high pretreatment CRP/ALB ratio and in whom the CRP/ALB ratio normalized after chemotherapy tended to have better overall survival than those in whom both the pretreatment and posttreatment CRP/ALB ratios were high. The CRP/ALB ratio is a useful marker for predicting survival and monitoring chemotherapeutic effectiveness in patients with unresectable metastatic colorectal cancer.
