Efficacy and safety of chemotherapy combined with iodine-125 seed brachytherapy for intermediate and advanced oncogenic driver gene-negative non-small cell lung cancer.

Purpose: To compare the effectiveness and safety of CT-guided iodine-125 seed brachytherapy in conjunction with chemotherapy against chemotherapy alone for the management of intermediate and advanced non-small cell lung cancer (NSCLC) lacking oncogenic driving genes.

Methods And Materials: Retrospective analysis was conducted on clinical data from 128 patients diagnosed with intermediate and advanced non-small cell lung cancer who received iodine-125 combined with chemotherapy or chemotherapy alone due to the absence of oncogenic driver gene mutations. The patients in two groups were compared at 6-month follow-up for objective remission rate (ORR), Disease control rate (DCR), local progression-free survival (LPFS), overall survival (OS), clinical symptom improvement, and adverse events.
