AbstractThe prognostic value of peripheral blood hemoglobin/red blood cell distribution width ratio (HRR) in colorectal cancer (CRC) is unclear. The aim of this study was to analyze the correlation between peripheral blood HRR and the prognosis of CRC. A retrospective study analyzed the medical records of 284 CRC patients who attended Linyi People Hospital between June 1, 2017 and June 1, 2021. The optimal diagnostic cutoff value for hemoglobin (Hb)/erythrocyte distribution width was determined by ROC curve as 3.098, and patients were divided into high- and low-level groups for comparative analysis of clinical data. Kaplan-Meier method was used for survival analysis, and logrank test was used to assess survival differences. In univariate and multifactorial analyses, Cox proportional risk regression models were used to assess independent risk factors for overall survival (OS) and progression-free survival (PFS). All statistical tests were bilateral probability tests with α = 0.05, and P < .05 was considered statistically significant. There were 284 patients who were finally included in the statistical analysis. Gender, tumor stage, Hb, platelets, and CEA were associated with PFS and OS. Tumor stage, Hb, and HRR (P < .05) were independent risk factors for PFS and OS. Low-level HRR was associated with poor patient prognosis. Low-level HRR is associated with poor patient prognosis and is a potential tumor prognostic marker.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
