Background: Stereotactic body radiotherapy (SBRT) is considered to be an effective and safe treatment in patients with primary lung cancer. If local recurrence is confirmed following SBRT, surgical treatment is a possibility. The present study aimed to clarify the safety and survival outcomes of salvage surgery in primary lung cancer patients with local recurrence following SBRT. Methods: All subjects were patients with primary lung cancer who underwent surgical treatment for local recurrence following SBRT during the period from July 2005 to July 2015. We evaluated the reason for SBRT selection, the surgical procedure, postoperative complications, and prognosis. Results: Of 932 patients underwent SBRT as treatment for primary lung cancer, 48 patients (5.2%) had local recurrence alone and 19 patients (2.0%) underwent salvage surgery. SBRT was selected in eight medically operable patients who refused surgery, and in 11 patients considered medically inoperable by their pulmonologist. Lobectomy was performed in 15 patients. Postoperative complications were documented in 4 patients (21.1%). Incomplete resection was performed in 2 patients. Stage progression was confirmed in 7 patients (36.8%). The 5-year overall survival (OS) was 72.5% and the 5-year disease-free survival (DFS) was 65.2%. Conclusions: We evaluated patients who underwent salvage surgery due to local recurrence of lung cancer following SBRT. We found that salvage surgery could be performed safely without affecting SBRT outcomes. We further infer that cases of complete resection are likely to be associated with good prognosis, and that SBRT should be selected only after careful consideration because complete resection is not possible in all cases.
