OBJECTIVES: The current retrospective study aimed to evaluate the association between combined preoperative and postoperative C-reactive protein-to-albumin ratio, which is correlated with prognosis in different types of malignancies, and prognosis after curative resection in patients with colorectal cancer.
METHODS: This study enrolled 263 patients who underwent curative resection for stage II/III colorectal cancer. C-reactive protein-to-albumin ratio was calculated within 30 days before and 7 days after surgery. Receiver operating characteristic curve analyses were performed to determine the optimal cutoff values of preoperative and postoperative C-reactive protein-to-albumin ratio. The correlations between combined preoperative and postoperative C-reactive protein-to-albumin ratio and prognosis were analyzed.
RESULTS: The cutoff values of preoperative and postoperative C-reactive protein-to-albumin ratio were 0.223 and 0.813, respectively; higher ratios were significantly associated with poor overall survival, based on the Kaplan-Meier curves (p < 0.001, p = 0.003, respectively). Further, preoperative and postoperative C-reactive protein-to-albumin ratios were correlated with poor progression-free survival (p < 0.001, p = 0.064, respectively). In the multivariate analysis, combined preoperative and postoperative C-reactive protein-to-albumin ratio was an independent predictor of overall survival and progression-free survival (p = 0.012, p = 0.044, respectively). Compared with low preoperative and postoperative C-reactive protein-to-albumin ratio, high ratios of that were significantly associated with poor overall survival (hazard ratio = 3.897, p = 0.006) and progression-free survival (hazard ratio = 2.130, p = 0.029).
CONCLUSIONS: Combined preoperative and postoperative C-reactive protein-to-albumin ratio, useful for prognostic prediction, can be a promising prognostic marker after curative resection in patients with colorectal cancer.
