Overview
- A global consortium published an analysis in Nature that examined tumour samples from 959 men and identified eight distinct mutational footprints that together explain about 85% of prostate cancers.
- Four of the eight footprints were linked to tumours more likely to spread beyond the prostate, giving researchers potential molecular markers of aggressive disease.
- The team found some footprints vary with patient age and ancestry, with certain patterns more common in Black men, which may help explain part of observed risk differences.
- Researchers from the Pan Prostate Cancer Group, which has amassed molecular data on over 2,000 prostate tumours, say the next steps are to build diagnostic assays, develop molecular classification systems and run clinical studies to validate the findings.
- If validated, the work could let doctors identify high‑risk cancers earlier and offer more personalized treatment, but assay development, regulatory review and prospective trials are needed before any change to routine screening or care.
