Eligibility Criteria

Inclusion

  • Aged 18 years or older, regardless of sex.
  • Pathologically confirmed, resectable non-small cell lung cancer (NSCLC); having received neoadjuvant therapy containing immune checkpoint inhibitors prior to surgery; without achieving pathological complete response (non-pCR) upon postoperative pathological assessment.
  • Molecular characteristics: Pre-treatment biopsy specimens tested negative for EGFR mutations and ALK fusions by DNA-based NGS or PCR methods.
  • Sample requirements: Availability of 5-10 formalin-fixed, paraffin-embedded (FFPE) sections prepared from surgical tissue specimens, with ≥5% tumor cell content confirmed by H\&E staining.

Exclusion

  • Failure to meet any one of the requisite eligibility criteria specified in the inclusion criteria.
  • History of a concurrent or prior malignancy at other sites.
  • Failure to complete the planned cycles of neoadjuvant immunotherapy due to treatment-related toxicities.
  • Any other condition that, in the judgment of the investigator, renders the patient unsuitable for participation in this study.
