Non-invasive early detection of cancer four years before conventional diagnosis using a blood test

X. Chen, J. Gole, et al.

Early cancer detection could drastically improve survival rates. This research, led by a team of renowned authors, reveals that a novel blood test identified multiple cancers in asymptomatic individuals up to four years before traditional diagnoses. The findings harbor significant implications for non-invasive cancer screening.

Abstract
Early cancer detection could significantly reduce mortality. This study uses the Taizhou Longitudinal Study (TZL) data, analyzing plasma samples from 605 asymptomatic individuals (191 later diagnosed with cancer) and 232 cancer patients, plus tissue samples. The PanSeer blood test, based on circulating tumor DNA methylation, detected five common cancers in 88% of post-diagnosis patients (96% specificity) and 95% of asymptomatic individuals who later developed cancer. This suggests potential for non-invasive cancer detection up to four years before conventional diagnosis.
