Prognostic Value of C-reactive Protein-to-albumin Ratio after Curative Resection in Patients with Colorectal Cancer.

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.
