Vanguard: a new blood test approach to screen for multiple cancers

Official title: The Vanguard Study: Testing a New Way to Screen for Cancer

Run by National Cancer Institute (NCI) · NCT06995898 · Data updated 2026-11-12

This study will test two different blood-based multi-cancer detection tests in adults 45–75 without cancer to see if they find cancers earlier than usual care.

Is this trial a fit for you?

Likely a good fit

Adults 45–75 years old without a solid or blood cancer diagnosis in the past five years who can give blood samples and complete consent and questionnaires in English, Spanish, or Arabic are ideal candidates.

Probably not a fit

People currently undergoing cancer diagnostic work-up, those with a recent (within five years) cancer diagnosis, those who are pregnant or breastfeeding, or those already in another investigational cancer screening study are not eligible and would not benefit from participating.

What this trial studies

This randomized feasibility study will enroll adults aged 45–75 without a recent cancer diagnosis and assign them to one of two multi-cancer detection (MCD) blood-test groups or a control group receiving usual care. Participants will provide blood at enrollment and again at one year, and researchers will collect medical record data to track results, follow-up diagnostics, and standard screening behaviors. The trial focuses on feasibility outcomes—recruitment, adherence, representativeness across sites, timeliness of result return, and diagnostic resolution of abnormal tests—rather than definitive effectiveness. Results will guide design and procedures for a larger randomized trial of MCD screening.

Why it matters

Potential benefit: If successful, these blood tests could help find cancers earlier, potentially improving treatment options and outcomes for patients.

How similar studies have gone: Several observational studies of blood-based multi-cancer detection tests have shown promising ability to detect multiple cancer types, but randomized trials proving reduced cancer deaths or clear benefit are still lacking.
