Results from a study in The Netherlands involving 13,715 patients showed that aspirin use after a cancer diagnosis significantly improved overall survival in patients diagnosed with a gastrointestinal cancer. In total, 30.5% of patients used aspirin pre-diagnosis, 8.3% were solely post-diagnosis users, and 61.1% had not taken aspirin at all. The commonest sites for tumours were colon (42.8% of patients), rectum (25.4%), and oesophagus (10.2%). Median follow-up time for all patients was 48.6 months, with 28% of patients surviving for at least five years. Patients using aspirin after their diagnosis had a chance of survival twice as high than that of those who did not use it in the same circumstances.
