Introduction/Objective. Locally advanced lung cancer is often accompanied by atelectasis of either a part or the entire lung. The aim of this study was to establish the benefits of brachytherapy on the patients’ quality of life, the length of the progression-free survival (PFS), and the overall survival (OS) as related to the presence or absence of atelectasis after the applied treatment. Methods. The total of 100 patients with locally advanced lung cancer or endobronchial metastasis of other malignancy were treated with the high-dose-rate endobronchial brachytherapy (HDR-EBB) in 2017. For observing the patients’ clinical characteristics, the PFS and OS, the patients were classified into four groups according to the presence of atelectasis before and after HDR-EBB. Results. After HDR-EBB alone or combined with other treatment modalities, a statistically significant symptom alleviation was registered for all the symptoms except cough (p < 0.05). The significantly highest PFS value was registered among the patients with atelectasis prior but not after HDR-EBB. The longest survival was registered in the patients who had atelectasis prior to, but not after HDR-EBB, as well as among the patients without atelectasis either before or after EBB. Conclusion. HDR-EBB is an efficient method that improved the quality of life of most patients. There were improved rates of re-aeration after HDR-EBB treatment alone and as a part of combined treatment. Reaeration after EBB is a positive prognostic factor with respect to PFS and OS of these patients.
