Summary

Story summary

Researchers at Mass General Brigham created HPV-DeepSeek, a blood test that can detect HPV-related head and neck cancers up to 10 years before symptoms arise.
HPV is responsible for approximately 70% of these cancers in the U.S., with no existing screening methods leading to late diagnoses.
The test employs whole-genome sequencing to find HPV DNA in blood, achieving 99% specificity and sensitivity.
In a study of 56 samples, it identified cancer in 22 of 28 patients who later developed the disease, with the earliest positive result from 7.8 years before diagnosis.
Ongoing validation studies will assess the test's effectiveness and inform future screening protocols.
