Evaluating cancer immunotherapy effectiveness in lung and esophageal cancer patients

Investigating the Biomarkers in Tumor Microenvironment and Peripheral Blood Microenvironment to Evaluate the Efficacy of Cancer Immunotherapy in Chest Cancer Patients

Observational The First Affiliated Hospital of Soochow University · NCT06790797

This study is testing how well immunotherapy works for people with lung and esophageal cancer by looking at changes in their immune cells before and after treatment.

What this trial studies

This observational study investigates the impact of immunotherapy on the immune status of patients with lung and esophageal cancer. Researchers will collect tumor tissue and peripheral blood samples before and after treatment to analyze changes in cancer-specific T-cell populations. Techniques such as single-cell RNA sequencing, multiplex immunohistochemistry, and flow cytometry will be employed to identify potential biomarkers that predict the efficacy of immunotherapy. The goal is to understand how these biomarkers correlate with treatment responses and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 80 with a confirmed diagnosis of lung or esophageal cancer who are set to receive PD-1/PD-L1 antibody immunotherapy.

Not a fit: Patients with hematogenic infectious diseases, immediate treatment needs, or severe mental illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prediction of immunotherapy responses, allowing for more personalized treatment plans for cancer patients.

How similar studies have performed: Other studies have shown promise in identifying biomarkers for immunotherapy efficacy, suggesting that this approach may yield valuable insights.
