Abstract
Purpose
The CRP/albumin (Alb) ratio, a recently reported predictor, has shown value for prognosis in various human cancers. This study aimed to determine the prognostic value of baseline CRP/Alb and to explore the relevance between postchemotherapy CRP/Alb and the efficacy of chemotherapy in advanced pancreatic cancer patients.
Patients and methods
Five hundred and ninety-five patients diagnosed with locally advanced or metastatic adenocarcinoma of the pancreas were enrolled. Cut-off Finder was used to calculate the best cut‑off value for baseline CRP/Alb. The primary endpoint was overall survival, which was analyzed by Kaplan-Meier survival curves with 95% confidence intervals. The log rank test and Cox proportional hazard model were used to evaluate the univariate and multivariate analyses.
Results
The optimal cut-off value for baseline CRP/Alb was determined to be 0.18. Both the baseline CRP/Alb (CRP/Alb≥0.18 vs. CRP/Alb<0.18, hazard ratio [HR] = 2.506; p<0.001) and postchemotherapy CRP/Alb (CRP/Alb≥0.18 vs. CRP/Alb<0.18, HR = 1.854; p =0.002) were significant predictors of overall survival according to multivariate analysis and were independent of other factors. Patients with a baseline and postchemotherapy CRP/Alb ≥0.18 had the worst prognosis.
Conclusion
CRP/Alb is a strong and useful indicator of prognosis for advanced pancreatic cancer. Both baseline and postchemotherapy CRP/Alb can be used in predicting the survival of patients and monitoring the effectiveness of chemotherapy in clinical practice.
