Prevalence and Impact of Frailty in Pancreatic Cancer: A Systematic Review and Meta-Analysis Based on 35,191 Patients

Abstract

Background: Frailty has been associated with increased mortality among patients with pancreatic cancer. Nevertheless, several lines of evidence regarding the prevalence of frailty in patients with pancreatic cancer and mortality in patients with pancreatic cancer and frailty have not been thoroughly investigated and require clarification.

Methods: A systematic review and meta-analysis of studies indexed in PubMed, Scopus, Web of Science, and Embase through March 2023 were conducted, and the pooled prevalence and relative risk (RR) estimate were calculated.

Results: A total of 18 studies containing 35,191 patients with pancreatic cancer were included. The prevalence of frailty in pancreatic cancer was 45% (95% CI = 29-62; I2 = 99.9%; p = 0.000). In patients with pancreatic cancer, frailty was associated with increased relative risk for mortality (RR = 1.70; 95% CI = 1.30-2.22; I2 = 84.8%, p = 0.000).

Conclusions: Frailty prevalence in pancreatic cancer is common and exerts a significant negative impact on the survival of patients with pancreatic cancer. Our findings are characterized by significant heterogeneity, and caution is warranted in their interpretation. However, these findings highlight the importance of evaluating frailty, which may provide prognostic data and inform decision-making priorities.
