简要总结
This is a observational, multicenter study, monitoring the circulating tumor DNA (ctDNA) in people who is at risk of cancers,assessing the sensitivity and specificity of ctDNA detection in early screening of pan-carcinoma.
详细描述
2000 patients with positive tumor protein markers or cancer screening were recruited. All patients were tested for ctDNA at enrollment and followed up at 6 months and 1 year. The study was completed at the time of cancer diagnosis or the longest follow-up time (1 year).
