What this trial studies

This study investigates the relationship between unintentional weight loss (UWL) and cancer detection using the GRAIL Galleri test, an investigational pan-cancer early detection test. Participants aged 40 to 80 will track their weight weekly using a Fitbit Aria Smart Scale for three years. Those who experience a weight loss of 5% or more will undergo further assessments, including the GRAIL Galleri test, health history evaluations, and necessary imaging or screenings. The goal is to determine if combining UWL detection with GRAIL testing can enhance early cancer detection rates.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 40 to 80 who can use a compatible device for weight tracking and are willing to participate in the study.

Not a fit: Patients currently diagnosed with cancer or actively trying to lose weight through medications or surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier detection of malignancies in patients experiencing unintentional weight loss.

How similar studies have performed: While the specific combination of UWL tracking and GRAIL testing is novel, similar studies have shown promise in early cancer detection methodologies.
