Meanwhile, PD-1 inhibitors, as a major focus of current research, have become an essential component of systemic therapy for non-small cell lung cancer. This case report describes a 72-year-old male patient with advanced non-small cell lung cancer(NSCLC) whose disease progressed despite multiple lines of chemotherapy and radiotherapy. Due to the onset of hemoptysis, he underwent combined treatment with radioactive 125I seeds and a PD-1 inhibitor. Postoperatively, his hemoptysis resolved completely, and notably, the patient achieved a progression-free survival of 40 months, demonstrating sustained clinical benefit. These findings suggest that the combination of 125I seed implantation and PD-1 inhibitors may exert a synergistic antitumor effect, offering a promising therapeutic strategy for elderly patients with advanced NSCLC.Keywords: non-small cell lung cancer, 125I seed implantation, brachytherapy, immunotherapy, synergistic therapy, elderly patients, immunotherapy
