Aspirin and other non-steroidal anti-inflammatory drug prescriptions and survival after the diagnosis of head and neck and oesophageal cancer

摘要

Background: Aspirin and other NSAIDs are widely used as analgesics and the former is a preventative agent for vascular events. It is unclear whether their long-term use affects cancer risk. Data on the chemopreventative role of these drugs on the mortality in patients with upper aerodigestive tract cancer (UADT) are insufficient. The aim of this study was to investigate the effect of aspirin and other NSAIDs on survival in UADT cancer patients.
