What this trial studies

This study aims to monitor non-small cell lung cancer (NSCLC) patients undergoing immunotherapy by quantifying cell-free DNA (cfDNA) through digital PCR. The primary goal is to evaluate the predictive value of cfDNA levels at the first reevaluation for clinical benefit. Additionally, the study will assess the early predictive value of cfDNA quantification before the second immunotherapy treatment and its correlation with disease progression. This longitudinal approach seeks to establish a robust biomarker for NSCLC treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with stage IIIA, IIIB, or IV non-small cell lung cancer who are undergoing immunotherapy.

Not a fit: Patients with other concurrent cancers or those who have had another cancer in the last 5 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable biomarker for predicting treatment response in NSCLC patients receiving immunotherapy.

How similar studies have performed: Other studies have shown promise in using cfDNA as a biomarker in cancer treatment, suggesting potential success for this approach.
