Screening and differentiating common cancers using blood tests

A Multicenter Prospective Diagnostic Test: Screening and Differentiating Common Cancers (Cancers of Lung, Stomach, Colorectum, Esophagus, Liver, Breast and Pancreas) Based on Peripheral Blood Cell-Free DNA Sequencing

Observational Air Force Military Medical University, China · NCT06036563

This study is testing a blood test that looks for signs of common cancers to see if it can help identify them early in people with and without suspicious lumps.

What this trial studies

This observational study aims to screen and differentiate various common cancers by analyzing cell-free DNA from peripheral blood samples. Participants, both with and without suspicious lesions, will provide blood samples for sequencing to develop a model that can effectively classify cancers, particularly in their early stages. The study will involve the collection of 15-20ml of blood and follow-up calls to monitor participants. The goal is to assess the effectiveness of this liquid biopsy approach in cancer diagnosis.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 20 to 80, either newly diagnosed with specific cancers or those without a cancer diagnosis.

Not a fit: Patients with uncontrolled systemic diseases or those who have undergone cancer treatment in the past three years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier and more accurate cancer diagnoses, improving patient outcomes.

How similar studies have performed: Other studies utilizing liquid biopsy and cell-free DNA sequencing have shown promise in cancer detection, suggesting potential success for this approach.
