NCT07533357

Brief Summary

The goal of this observational study is to to determine whether patients with a high proportion of precursor exhausted T cells (Tpex) in negative tumor draining lymph nodes have longer overall survival. The main question it aims to answer is: Whether precursor exhausted T cells (Tpex) in negative tumor-draining lymph nodes have better predictive efficacy for treatment response than PD-L1 CPS.

  • Any active autoimmune disease or a history of autoimmune disease
  • Disease progression occurs within 3months after PD-1 immunotherapy.
  • Allergic to macromolecular protein preparations, or to any of the ingredients in PD-1 inhibitors for injection.
  • Uncontrolled heart diseases or clinical symptoms
  • Congenital or acquired immunodeficiency (such as HIV infection); active hepatitis B (HBV-DNA≥104 copy number/ml) or hepatitis C (positive hepatitis C antibody, and HCV-RNA is higher than the detection limit of the analytical method); active tuberculosis.
