Prognostic Value of Systemic Inflammatory Markers and Scoring Systems in Predicting Postoperative 30-Day Complications and Mortality in Colorectal Cancer Surgery: A Retrospective Cross-Sectional Analysis.

Abstract

Aim: Cancer-related systemic inflammation causes the increase of proinflammatory markers and acute phase proteins. Activation of systemic inflammatory response has been linked to poorer prognosis in colorectal cancer. This study aims to evaluate the prognostic value of preoperative systemic inflammatory markers and inflammation/nutrition scoring systems in predicting the postoperative early period (first 30 days) complications and mortality outcomes of patients who underwent curative surgery for colorectal cancer in our clinic.

Methods: This study was designed as a retrospective single-arm cross-sectional study. In this study, 300 patients older than 18 years of age who underwent open and laparoscopic surgery for colorectal cancer were included. Demographic characteristics of the patients, preoperative hemogram and biochemical values, operation characteristics, postoperative tumor pathologies and disease stages were recorded.

Results: Neoadjuvant chemoradiotherapy, Systemic Inflammation Score, Modified Glasgow Prognostic Score, Naples Prognostic Score and Prognostic Nutritional Index had a significant effect on the first 30-day mortality (p-values: <0.001, 0.007, <0.001, <0.001, <0.001, respectively).

Conclusions: The results suggest that certain preoperative inflammation and nutrition scores might serve as indicators for potential early postoperative adverse outcomes in colorectal cancer surgery.
