Frailty Score and Postoperative Morbidity in Colorectal Cancer Surgery

Summary

This prospective observational study aims to evaluate the independent predictive value of the Edmonton Frailty Index (EFI) in estimating postoperative morbidity among older patients undergoing elective colorectal cancer surgery. Frailty, characterized by a decline in physiological reserves and increased vulnerability to stressors, has been recognized as a stronger predictor of adverse postoperative outcomes than chronological age alone. While the relationship between frailty and surgical outcomes has been extensively investigated in general surgical populations, data specifically focusing on patients with colorectal cancer remain limited. In this study, patients aged 65 years and older scheduled for elective colorectal cancer surgery will undergo preoperative frailty assessment using the validated Edmonton Frailty Index (EFI). Postoperative complications, length of intensive care unit (ICU) stay, total hospital stay, and 30-day adverse outcomes, including mortality, myocardial infarction, pulmonary embolism, sepsis, and the need for reoperation, will be recorded and analyzed. The primary objective is to determine whether frailty, as measured by the Edmonton Frailty Index, serves as an independent predictor of postoperative morbidity in this specific patient population. Secondary objectives include exploring associations between frailty and intraoperative variables such as blood loss, fluid administration, and vasopressor requirements. By addressing this gap, the study aims to contribute to the growing body of evidence supporting the routine incorporation of frailty assessment into preoperative risk stratification protocols for older patients with colorectal cancer. The ultimate goal is to enhance perioperative risk assessment, optimize perioperative care, and improve patient outcomes.
