Quality of Life Instruments and Trajectories After Pancreatic Cancer Resection: A Systematic Review.

ABSTRACT: This systematic review aimed to investigate the instruments available to measure quality of life (QOL) after pancreatic cancer surgery and to describe short- and long-term QOL outcomes. A comprehensive literature search was completed using PubMed, Embase, and Medline from inception to March 2019. Studies investigating QOL outcomes in patients undergoing pancreatic cancer surgery who were 18 years or older were included. The main outcomes of interest were QOL instruments and short (≤6 months) and long term (>6 months) QOL outcomes. The overarching domains of physical, psychosocial, overall QOL, symptoms, and other were used to summarize QOL outcomes. Thirty-five studies reporting on 3573 patients were included. Fifteen unique QOL instruments were identified, of which 4 were disease-specific instruments. Most of the included studies reported no changes in QOL at short- and long-term follow-ups for the overarching domains. No difference in QOL outcomes was reported between different surgical approaches, except laparoscopic versus open distal pancreatectomy, and pancreaticoduodenectomy versus distal pancreatectomy. There are a wide range of instruments available to measure QOL outcomes in pancreatic cancer surgical patients, although only few are disease-specific. Most of the included studies reported no significant changes in QOL outcomes at short- or long-term follow-ups.
