Of the 68, initial surgery was performed in 15 patients (22.1%), while the remaining 53 (77.9%) received antibiotic therapy initially. In the initial antibiotic group, 45\/53 (84.9%) were cured without relapse (median antibiotic duration 5.3 months). 5\/53 (9.4%) patients were refractory medically (median antibiotic duration 9.7 months), and 3\/53 (5.7%) experienced a recurrence (median time to relapse 35.3 months). In the initial surgery group, 14\/15 (93.3%) were cured and treatment failure occurred in one (6.7%). In the multivariate analysis, the absence of an antibiotic response at 1 month was the only independent factor associated with a poor treatment outcome, with an adjusted odds ratio of 49.2 (95% CI, 3.34\u2013724.30). There was no significant difference in treatment outcome based on the size of the parenchymal lesion, comorbidities, whether intravenous antibiotics were used, antibiotic therapy duration, or whether the initial treatment was surgical.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Antibiotic treatment with or without surgery was effective for treatment of pulmonary actinomycosis.
