The sCD14-ST predictive value in the development of adverse outcomes in operated colorectal cancer patients (diagnostic study)

Abstract

Background: The main aim was to analyze dynamic changes in the level of soluble CD14 subtype (sCD14-ST) in blood serum and assess it as a possible risk factor for the development of systemic inflammatory response syndrome, infectious and inflammatory complications, organ dysfunction, and mortality in operated colorectal cancer (CRC) patients. Materials and methods: For the period 2020–2021, 90 operated CRC patients were examined. Patients were divided into two groups: 1 – 50 patients operated on for CRC without acute bowel obstruction (ABO); 2 – 40 patients operated on for tumor ABO caused by CRC. To determine sCD14-ST by the ELISA (enzyme-linked immunosorbent assay) method, venous blood was taken 1 h before surgery and 72 h after it (third day). Results: sCD14-ST levels were higher in CRC patients with ABO, organ dysfunction, and dead patients. If the sCD14-ST level on the third day after surgery is greater than 520 pg/ml, the risk of a fatal outcome is 12.3 times higher than at its lower level [odds ratio (OR): 12.3, 95% CI: 2.34–64.20]. With the increase in the sCD14-ST level on the third day after surgery from baseline or its decrease by no more than 8.8 pg/ml, the risk of organ dysfunctions is 6.5 times higher than with its greater decline (OR: 6.5, 95% CI: 1.66–25.83). Conclusions: This study has demonstrated that in CRC patients, sCD14-ST can be used as a predictive criterion for the development of organ dysfunction and death. Significantly worse results and prognosis were observed in the patients with higher levels of sCD14-ST on the third day after surgery.
