Abstract
Purpose: The clinical significance of the red blood cell distribution width (RDW) in patients with rectal cancer undergoing preoperative chemoradiotherapy (CRT) followed by surgery has not been fully evaluated. Methods: In this retrospective study, we investigated the association between the RDW and the prognosis in 120 patients with locally advanced rectal cancer (LARC). We also performed a subgroup analysis limited to patients with pathological TNM stage I–II (ypN[−]) LARC. Results: The RDW standard deviation was used to evaluate the RDW. We set 47.1% as the cut-off value of the RDW for the assessment of the prognosis. The RDW exhibited a significant negative relationship with the serum hemoglobin and albumin levels. An elevated RDW was an independent prognostic factor for the overall survival (OS) and disease-free survival (DFS) in patients with LARC. In addition, an elevated RDW predicted a poor OS and DFS in patients with pathological TNM stage I–II (ypN[−]) LARC. Conclusions: The RDW is a promising predictor of a poor survival and recurrence in patients with LARC treated by CRT.
