Dynamic Granulocyte Turnover Inferred From cfDNA Methylation Predicts Immunotherapy Benefit in Liver‐Metastatic Small Cell Lung Cancer: A Prospective Biomarker Study
Liver metastases (LM) in small cell lung cancer (SCLC) are associated with a limited response to immune checkpoint inhibitors (ICIs). In this trial, we evaluated the efficacy of first‐line envafolimab plus chemotherapy in SCLC patients with LM and explored potential predictive biomarkers. Patients received envafolimab...
