Relationship Between Systemic Inflammatory Response Exponents, Levels of ADAM10, ADAM17 Proteins and Selected Clinical Parameters in Patients with Colorectal Cancer: Original Research Study.

Chronic inflammation is a confirmed risk factor for colorectal cancer (CRC). Indicators of systemic inflammatory response (SIR), such as neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR), are easily accessible indicators of the generalized inflammatory response. At the molecular level, inflammation-related carcinogenesis involves proteins from the adamalysin family: ADAM10 and ADAM17. The aim of the study was to assess NLR and PLR and their relationship with selected clinical parameters in CRC patients, as well as the correlation between ADAM10 and ADAM17 in tumor tissue and matched surgical margins with NLR and PLR values. Tumor tissue material matched surgical margins, and blood was collected from 66 patients who underwent surgery because of CRC. The concentrations of ADAM10 and ADAM17 in the collected material were tested using the enzyme-linked immunosorbent assay (ELISA) method. SIR parameters (NLR, PLR) were also determined. The results were statistically analyzed and compared with selected clinical parameters. Results: The study showed that PLR was lower in patients with comorbid cardiovascular diseases (CVD). In patients who underwent preoperative treatment, both the NLR and PLR values were higher than in patients who underwent primary surgery. There was also a negative correlation between ADAM17 concentrations in the surgical margin and PLR values. In conclusion, the presence of additional diseases such as CVD or diabetes mellitus type 2 (DMT2) or the use of preoperative treatment should be taken into account when assessing SIR parameters in CRC patients. Moreover, no clear correlations have been found between ADAM10 and ADAM17 and SIR parameters.
