After a median of 20 months of follow-up and 191 iDFS occasions (107 within the aspirin group; 84 within the placebo group), the stratified hazard ratio evaluating aspirin with placebo was 1.27, which was higher than the prespecified hazard ratio for futility of 1.03. There was no distinction noticed between the teams within the frequency of grade 3/4 hostile occasions. Throughout arms, the nonprotocol use of aspirin/nonsteroidal anti-inflammatory medication was comparable and fewer than 14 p.c.
“Though irritation should still play a task in most cancers development, aspirin is just not advisable for prevention of breast most cancers recurrence,” Chen stated in a press release.
