Abstract
Purpose
Associations between the preoperative absolute neutrophil count (NC), lymphocyte count (LC), and monocyte count (MC) in the peripheral blood and the prognosis of colorectal cancer (CRC) patients have not been widely studied.
Methods
We enrolled 361 patients who underwent surgery for CRC between January 2007 and December 2013 to analyze correlations among the LC, MC, and NC and prognosis.
Results
Based on cut-off values determined by a receiver operating characteristic analysis, patients were subgrouped as LymphHigh or LymphLow (cut-off: LC = 1460 cells/µL); as MonoHigh or MonoLow (cut-off: MC = 421 cells/µL); and as NeutHigh or NeutLow (cut-off: NC = 3247 cells/µL). Patients were then given lymphocyte–monocyte–neutrophil (LMN) scores by adding the points of their different subgroups (1 point each for LymphLow, MonoHigh and NeutHigh; 0 points for LymphHigh, MonoLow and NeutLow). The 5-year overall survival rates significantly differed by the LMN score (0: 89.7%, 1: 80.6%, 2: 68.8%, and 3: 57.4%; P < 0.0001). In the multivariate analysis, the LMN score was found to be an independent prognostic indicator.
Conclusions
The combination of the preoperative absolute number of lymphocytes, monocytes, and neutrophils is a useful prognostic indicator in CRC patients.
