摘要
Colorectal cancer (CRC) is one of the most common malignant cancers worldwide. Patients with CRC are diagnosed based on various predictors, including performance status, clinicopathological factors and TNM classification. The aim of the present study was to analyze the neutrophil and lymphocyte counts, as well as the neutrophil-to-lymphocyte ratio (NLR) in pre- and postoperative blood samples of patients with CRC in correlation with specific anatomical variables and disease- free survival (DFS). The variables pre- and postoperative neutrophil count (preNEU and postNEU, respectively), lymphocyte count and NLR were significantly higher in cancer patients than those noted in healthy subjects (all P<0.001). PreNEU count correlated with tumor size, necrosis and tumor budding (R=0.204, P=0.014; R=0.189, P=0.023; R=-0.174, P=0.036, respectively). Moreover, postNEU was associated only with the histological type (R=0.174; P=0.047). The PreLYMPH count was correlated with distant metastasis (R=-0.153, P=0.046). PreNLR and postNLR were associated with the expression of various histological markers of disease progression. Analysis of DFS indicated that the postNEU count in the low group exhibited a tendency to lower DFS duration, although the results were not significant (P=0.055). In conclusion, the present study indicated a significant correlation between the factors analyzed in blood samples of CRC patients and the disease progression markers.
