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.
