Aspirin Shows No Benefit and Potential Harm in Colorectal Cancer Liver Metastases, Phase 3 Trial Finds
- Daily adjuvant aspirin at 160 mg failed to improve disease-free survival in patients with colorectal cancer liver metastases compared to placebo in the randomized phase 3 ASAC trial.
- The aspirin group showed a numerically higher risk for death that nearly reached statistical significance, with more adverse events and serious complications.
- Results indicate the protective effects of aspirin observed in non-metastatic colorectal cancer do not translate to patients with liver metastases.
- Researchers plan subgroup analyses for PIK3CA, PTEN, and KRAS mutations to identify potential patient populations who might benefit from aspirin therapy.
