This study assessed the efficacy and safety of radioactive iodine-125 seed ablation brachytherapy (RSABT) in comparison to microwave ablation therapy (MWAT) for treating inoperable stage I non-small cell lung cancer (NSCLC). We conducted a retrospective analysis of data from stage I NSCLC patients who underwent CT-guided RSABT or MWAT. The primary outcomes measured were progression-free survival (PFS), overall survival (OS), and the occurrence of adverse events. Of the patients included in the study, 71 underwent RSABT and 105 received MWAT. The median follow-up time for these groups was 47.4 months and 60 months, respectively. The PFS rates at 1-year, 3-year, and 5-year for the RSABT group were 87.3%, 72.6%, and 65.8%, while for the MWAT group, they were 89.5%, 69.3%, and 43.7%, respectively (P = 0.011). The OS rates at 1-year, 3-year, and 5-year for the RSABT group were 97.2%, 78.1%, and 66.1%, and for the MWAT group, they were 99%, 75.8%, and 55%, respectively (P = 0.112). Upon multivariate analysis, the treatment modality was identified as an independent predictor of PFS (P = 0.008). Additionally, both sex and T stage were found to be independent predictors of both PFS and OS (P < 0.05). Adverse events, such as pneumothorax, occurred in 50% of the MWAT group and 39% of the RSABT group (P = 0.313). The incidence of pleural effusion was 44% in the MWAT group compared to 14% in the RSABT group (P < 0.001). Needle bleeding was observed in 32% of the RSABT group and 5% of the MWAT group (P < 0.001). We conclude RSABT demonstrates promising efficacy and safety in the treatment of stage I NSCLC. However, further studies are essential to validate these preliminary findings.
