[Pulmonary Resection for Malignant Tumor after Stereotactic Radiation Therapy].
We describe our experience with 14 patients who underwent surgery for a recurrent malignant lung tumor following stereotactic radiation therapy (SRT). The reasons for selecting SRT were patients'decision in 7 patients, advanced age in 3, reduced lung function in 3, and comorbidity in 1. Eight patients had primary lung cancer and 6 had metastatic lung cancer. Tumor recurrence was diagnosed by chest computed tomography in all patients except for one. The median period from SRT to surgery was 12.2 months. All 14 patients were deemed fit for surgery;5 patients underwent lobectomy, and 9 underwent limited resection. In 13 patients, complete resection was possible. In all 14 patients, lung resection was performed safely, and postoperative course was uneventful. No patients died of cancer during follow-up. Informed consent should be obtained from patients for post-recurrence treatment because tumor recurrence can occur after SRT.
