Background/Aim: This study was designed to evaluate the clinical significance of the C-reactive proteinto- albumin ratio (CAR) in patients with rectal cancer undergoing preoperative chemoradiotherapy (CRT) followed by surgery. Patients and Methods: This retrospective study evaluated the correlation between CAR and prognosis in 115 patients with locally advanced rectal cancer. We also carried out subgroup analyses limited to patients with low modified Glasgow prognosis score (mGPS) (score 0) or pathological TNM stage I-II [ypN(-)]. Results: CAR exhibited significant relationships with sex, tumor invasion, recurrence, serum carcinoembryonic antigen, and mGPS. Elevated CAR was an independent prognostic factor for overall survival (OS) and disease-free survival (DFS) among all patients. Elevated CAR also predicted poor OS and DFS in patients with pathological TNM stage I-II [ypN(-)] and low mGPS score. Conclusion: CAR is a promising predictor of survival and recurrence in patients with rectal cancer treated by CRT.
