We analyzed the clinical courses of 271 patients with treatment-refractory MAC-PD who discontinued therapy after at least 12 months. Patients were categorized into two groups\u2014the retreatment group, who resumed antibiotics due to clinical or radiological deterioration, and the stable group, who did not require antibiotics. Of the study patients, 138 (51%) were in the retreatment group, whereas 133 (49%) were in the stable group. In the multivariate analysis models, an elevated erythrocyte sedimentation rate (adjusted hazard ratio [aHR] =1.01), the presence of a cavity (aHR = 1.75), and the number of lobes affected by bronchiectasis (aHR = 1.21) were associated with the need for retreatment. Our data indicated that approximately 50% of the patients with refractory MAC-PD who discontinued antibiotics eventually required retreatment, which was influenced by the extent of lung destruction or inflammation. These findings can aid in determining treatment strategies for patients with refractory diseases.\n            <\/jats:p>\n
