Abstract

AIM: To evaluate changes in pulmonary function tests (PFTs) at different follow-up durations after stereotactic body radiotherapy (SBRT) and surgery in stage I and II non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS: Differences between pre-treatment- and follow-up PFTs were analyzed in 93 patients treated with surgery and 30 patients treated with SBRT for NSCLC. Follow-up durations were categorized into: early (0-9 months), middle (10-21 months) and late (≥22 months). Wilcoxon signed-rank test was used to analyze differences between pre-treatment and follow-up PFTs.

RESULTS: Forced expiratory volume in one second, forced vital capacity and diffusion capacity for carbon monoxide corrected for the actual hemoglobin level significantly diminished after surgery for all follow-up durations: 11-17% of predicted values. After SBRT, PFTs remained stable, but a declining trend of 6% (p=0.1) was observed after 22 months.

CONCLUSION: SBRT might lead to less treatment-related toxicity measured by PFTs than surgery in both the short and long term.
