Evaluating a biomarker model for assessing lung nodules

A Combined Biomarker Model for Risk Stratification of Indeterminate Pulmonary Nodules A Multicenter Prospective Observational Pilot Study

Observational Vanderbilt-Ingram Cancer Center · NCT06074133

This study is testing a new combined biomarker model to see if it can better help doctors understand the risk of indeterminate lung nodules compared to the current method.

What this trial studies

This prospective, multicenter observational study aims to estimate the clinical utility of a combined biomarker model (CBM) for risk stratification of indeterminate pulmonary nodules (IPNs). It will compare the CBM score, which includes hs-CYFRA 21-1 and radiomics, to the established Mayo Model. The study also seeks to establish standard operating procedures and protocols for future randomized control trials, ensuring that data collection and analysis are efficient and clinically relevant. Participants will undergo blood collection and chest CT scans as part of the evaluation process.

Who should consider this trial

Good fit: Ideal candidates are adults over 21 with intermediate-risk indeterminate pulmonary nodules measuring 8-30mm.

Not a fit: Patients with pure ground glass nodules, those currently undergoing cancer therapy, or with a history of primary lung cancer in the last 5 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of risk assessment for patients with indeterminate pulmonary nodules, leading to better clinical decision-making.

How similar studies have performed: Other studies have shown promise in using biomarker models for lung nodule assessment, but this specific approach is novel.
