Exploring biomarkers in lung cancer treatment before surgery

A Prospective Cohort Study to Explore Biomarkers for Response to Neoadjuvant Chemoimmunotherapy in Stage II-III Non-small Cell Lung Cancer

Observational Yonsei University · NCT06907160

This study is testing if blood and tissue samples can help doctors figure out which patients with lung cancer will benefit from treatment before surgery.

What this trial studies

This study aims to analyze tissue and blood-based biomarkers in patients with clinical stage II-III non-small cell lung cancer (NSCLC) undergoing neoadjuvant chemoimmunotherapy followed by surgery. It will involve collecting clinical, pathological, and radiological data from a cohort of patients, along with plasma samples taken before and after the neoadjuvant treatment. The goal is to identify non-responders to immunotherapy at diagnosis and to predict pathological complete response using non-invasive blood tests.

Who should consider this trial

Good fit: Ideal candidates are adults over 19 years old with histologically confirmed clinical stage II-III NSCLC and no driver mutations.

Not a fit: Patients under 19 years of age, those with serious medical conditions affecting compliance, or pregnant women may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment strategies for lung cancer patients, improving outcomes by identifying effective therapies early.

How similar studies have performed: Other studies have shown promise in using biomarkers for predicting treatment responses in lung cancer, suggesting this approach may be effective.

Eligibility criteria

Inclusion Criteria:

* Histologically proven clinical stage II-III lung cancer patients
* No driver mutations (EGFR mutation and ALK alteration)
* Whole body performance (ECOG) 0-1
* Those over 19 years of age
* Subject who submitted Informed consent form

Exclusion Criteria:

* Under 19 years of age
* If there is a history of causing infection or other serious medical problems that impair the patient's function and make it difficult to comply with the study protocol.
* Patients for whom the investigator determines that the patient should not participate in the clinical trial because the patient is judged to be unable to comply with the clinical trial procedures and requirements (a person lacking medical capacity)
* Other patients (pregnant women, etc.) determined by the clinical trial director to be unsuitable for this clinical trial.
