The aim of the present study was to investigate the outcomes of esophageal cancer (EC) patients with isolated synchronous brain oligometastasis (oligo-BM) treated with chemoradiotherapy (CRT) of the primary site and localized treatment of the BM with surgery, radiotherapy (RT) or radiosurgery. Of 125 EC patients investigated, seven patients (6%) had solitary BM. Six patients were diagnosed prior to, and one patient was diagnosed during, treatment. All patients were treated with neoadjuvant chemotherapy and whole-brain RT (WBRT) for BM. All but one patient received definitive CRT with a median RT dose of 50.4 Gy using conventional fractionation RT. The median age at diagnosis was 59 years (range, 48-77 years). Six patients succumbed to mortality, and one continued to receive systemic chemotherapy at the last visit. The median survival time of the patients was 18.9 months (range, 10.0-27.2 months). Median time to progression after completion of the treatments was 8 months (range, 3-9 months). Two patients had progression of the primary tumor, and one patient had progression of the BM. The neurological status of three patients with BM who were identified during the staging work-up did not deteriorate as a consequence of WBRT. In conclusion, the present study has demonstrated that aggressive treatment of the primary tumor and oligo-BM in patients with EC may prolong the survival time.
