Pancreatic exocrine insufficiency and pancreatic enzyme replacement therapy in patients with advanced pancreatic cancer: A systematic review and meta‐analysis

A total of 11 studies were included; seven studies reported the prevalence of pancreatic exocrine insufficiency and seven the effect of pancreatic enzyme replacement therapy in advanced pancreatic cancer. The pooled prevalence of pancreatic exocrine insufficiency in advanced pancreatic cancer was 72% (95% confidence interval: 55-86%), being significantly higher when tumours were located in the pancreatic head (relative risk = 3.36, 1.07-10.54; <i>p</i> = 0.04) six studies investigated the impact of pancreatic enzyme replacement therapy on survival/quality of life. Pancreatic enzyme replacement therapy was associated with 3.8 months (95% confidence interval: 1.37-6.19) survival benefit. Patients receiving pancreatic enzyme replacement therapy had a trend towards a better quality of life.<b>Conclusions</b> The prevalence of pancreatic exocrine insufficiency in advanced pancreatic cancer is substantial and its treatment can improve the outcomes of these patients.
