Low-dose aspirin use and cancer characteristics: a population-based cohort study.

ABSTRACT:

Background

Long-term daily use of aspirin has been associated with reduced cancer mortality. To explore this association, we compared tumour TNM characteristics among aspirin users with those among non-users.

Methods

From the Swedish Cancer Register, we identified patients diagnosed with colorectal, lung, prostate and breast cancers between 2006 and 2009 and matched them to the Swedish Prescribed Drug Register to obtain information on low-dose aspirin use prior to diagnosis. Contingency table and logistic regression analyses were used to test for association and obtain odds ratios (ORs).

Results

We identified 17,041 colorectal, 9766 lung, 29,770 prostate and 20,299 breast cancer patients. The proportion of low-dose aspirin users was ~26% among colorectal, lung and pro
