Role of Serum C-C Motif Chemokine Ligand 2 Monocyte Chemotactic Activities in Patients with Non Small Cell Lung Cancer

Abstract

To examine C-C motif chemokine ligand 2 chemotactic activities, expression and clinical relevance in the peripheral serum of non-small cell lung cancer patients is the objective of the study. The non-small cell lung cancer group consisted of 128 patients diagnosed with the disease in our institution between January 2018 and March 2022, while the healthy group consisted of 112 individuals. By using an enzyme-linked immunosorbent assay, the two group’s peripheral serum was examined for C-C motif chemokine ligand 2 expression levels. The monocyte chemotactic activity of blood plasma from the two groups was assessed using the Transwell chamber technique after human monocytic leukaemia cell line THP-1 cells were grown. Analysis was done on C-C motif chemokine ligand 2 expression levels and the relationship between monocyte chemotactic activity and histopathological features in non-small cell lung cancer patients. Age and gender did not significantly connect with the expression level of C-C motif chemokine ligand 2 or its monocyte chemotactic activity (p>0.05); however, smoking, pathological categorization, tumor, nodes and metastases stage, tumor stage, nodes stage and tumor diameter did (p<0.05). The expression level of C-C motif chemokine ligand 2 was 235.4±25.7 pg/ml in the peripheral serum of non-small cell lung cancer patients and 45.7±10.5 pg/ml in the healthy population; the monocyte chemotactic activity of non-small cell lung cancer patients was 236.5 % and that of healthy people was 86.5 %. They differed from one other in a statistically significant way (p<0.05). In comparison to the normal control group (r=0.87), the lung cancer group’s correlation coefficient between blood C-C motif chemokine ligand 2 and monocyte chemotactic activity was considerably lower (r=0.39). Patients with non-small cell lung cancer patients exhibit inadequate monocyte chemotactic activity, which may one day be targeted therapeutically.
