Patients and Methods: Oligometastases from the esophagus were identified from a dataset of a Japanese survey. The Kaplan–Meier method and Cox regression were applied to perform analyses. Results: A total of 114 patients with 132 pulmonary oligometastases were collected. The 3-year local control rate, freedom from further metastasis (FFFM) rate and overall survival (OS) rate were 70.2%, 25.3% and 37.5%, respectively. Performance status (PS) (PS 1 vs. PS 0, p<0.01), disease-free interval (p=0.03) and history of local therapy for metastasis (p=0.01) had significant relationships with FFFM and only PS was an independent prognostic factor for OS (PS 1 vs. PS 0, p=0.02; PS 2-3 vs. PS 0, p=0.04). Conclusion: SBRT for pulmonary oligometastases from esophageal cancer provided good local control and survival.
