ObjectiveTo analyze the value of combined detection of tumor markers, neutrophil to lymphocyte ratio (NLR), D-dimer and T lymphocyte in the diagnosis of colon cancer.MethodsThis is a retrospective study. A total of 80 patients with colon cancer and 80 patients with benign colon mass admitted to Baoding NO.1 Central Hospital from June 10, 2021 to December 10, 2022 were divided into the study group and the control group. Further comparison was performed on the tumor markers, NLR, D-dimer and T-lymphocyte levels between the two groups, associated with the comparison of corresponding levels of colon cancer at different stages. In addition, correlation analysis was carried out focusing on the above indicators with colon cancer.ResultsCarcinoembryonic antigen (CEA), CA199, NLR, D-dimer and CD8+ cell count levels in the study group were significantly higher than those in the control group, while CD4+ cell count and CD4+/CD8+ ratio were obviously lower (P<0.05). Among I-IV colon cancer, the highest levels of CEA, CA199, NLR, D-dimer, CD4+ and CD4+/CD8+ ratio were found in patients with Stage-IV colon cancer, while the level of CD8+ was the lowest (P<0.05). Correlation analysis indicated that CEA, CA199, NLR, D-dimer and CD8+ were positively correlated with whether the patient had colon cancer (r=0.841, 747,991,889,565, all P<0.05), but negative correlations with CD4+ and CD4+/CD8+ ratio (r=-0.999, -0.994, all P<0.05).ConclusionThe detection of tumor markers combined with NLR, D-dimer and T-lymphocytes has reference value in the diagnosis of colon cancer.Copyright: © Pakistan Journal of Medical Sciences.
