Abstract
Introduction: New evidence has emerged on the impact of frailty on prognosis in colon cancer, but the findings are not always consistent and conclusive. The aim of this systematic review was to assess the effect of frailty on postoperative complications and mortality in patients with non-metastatic colon cancer (CC) aged 65 years and older. Materials and Methods: We systematically searched for original studies published in the PubMed and Web of Science databases up to June 2021. Two independent reviewers selected the studies and extracted predefined data. A meta-analysis was performed using the random effects model to assess the effect of frailty on 30-day, 3- to 6-month and 1-year mortality, survival, and postoperative complications. Results: The search yielded 313 articles, of which 14 were included in this systematic review. The meta-analysis showed an effect for frailty on 30-day, 3- to 6-month, and 1-year mortality with respective pooled odds ratios (ORs) of 3.67 (95% confidence interval [CI] 1.53-8.79, p = 0.004), 8.73 (95% CI 4.03-18.94, p < 0.0001), and 3.99 (95% CI 2.12-7.52, p < 0.0001). Frailty also had an effect on survival, with a pooled hazard ratio of 2.99 (95% CI 1.70-5.25. p < 0.0001), and on overall and severe postoperative complications with pooled ORs of 2.34 (95% CI 1.75-3.15; p < 0.0001) and 2.43 (95% CI 1.72-3.43; p < 0.0001), respectively. Discussion: Frailty in older patients with CC is a risk factor for postoperative complications and mortality in the short term (30 days), medium term (3-6 months), and long term (1 year).
