What this trial is about
This study aims to investigate the impact of immunotherapy on the immune status of tumor microenvironment and peripheral blood of chest cancer patients. To do so, the investigators plan to collect tumor tissue and peripheral blood samples before and after immunotherapy, and use single-cell RNA sequencing, Multiplex immunohistochemistry, and flow cytometry. The investigators will analyze changes in the proportion of cancer cell-specific T-cell subpopulations related to treatment response before and after therapy, and seek biological markers that can predict the efficacy of immunotherapy.
