Pancreatic enzyme replacement therapy (PERT) for malabsorption in patients with metastatic pancreatic cancer

Abstract

Purpose: The diagnosis of metastatic pancreatic cancer (PC) carries a poor prognosis. PC is associated with weight loss and malabsorption in high rates secondary to pancreatic exocrine insufficiency. UK and USA guidelines exist recommending the empiric use of pancreatic enzyme replacement therapy (PERT) for quality of life in these patients. The aim of this study is to review the use of PERT in patients with metastatic PC referred to a specialist palliative care service.

Methods: Retrospective observational study of patients referred to the service between January 2010 and July 2012 with a diagnosis of PC. Information about PERT use, tumour site and frequency of symptoms was collected.

Results: 129 patients were referred, with a higher number in the eighth decade. Only 21% of this study group were prescribed PERT. Over 70% of patients had symptoms that could be attributable to malabsorption, mainly abdominal pain. Other symptoms such as bloating, wind and steatorrhoea were also common.

Conclusions: Guidelines recommending empiric treatment of PERT in patients with metastatic PC are not currently being utilised.
