N2 - BACKGROUND. Esophageal carcinoma rarely metastasizes to the brain. The objectives of the current study were to assess the frequency of brain metastasis from an esophageal primary tumor, to determine correlates of survival, and to describe treatment modalities and their outcomes. METHODS. Between June, 1993 and July, 2001, 1588 patients with a primary esophageal carcinoma registered at The University of Texas M. D. Anderson Cancer Center; of those, 27 patients (1.7%) had a diagnosis of brain metastasis. The authors collected demographic and clinical data and performed a statistical analysis. RESULTS. The median age at the time patients were diagnosed with brain metastasis was 62 years. Tumor histologies were adenocarcinoma in 22 patients (82%), unclassified carcinoma in 3 patients (11%), and squamous cell carcinoma in 2 patients (7%). Twenty patients (74%) experienced symptoms related to the brain metastasis. The metastases were treated with whole-brain radiation therapy (WBRT) alone in 15 patients (56%), and 10 patients (37%) underwent surgical resection, 4 of whom (15%) also received WBRT. Two patients (7%) underwent stereotactic radiosurgery. The median survival for the entire cohort after diagnosis of the primary tumor was 12.6 months (95% confidence interval [CI], 2.17-22.5 months), and the median survival after the diagnosis of brain metastasis was 3.8 months (95% CI, 1.1-6.5 months). The longest median survival observed after the diagnosis of brain metastasis (9.6 months) occurred in patients with a single brain lesion who underwent resection and received WBRT. There was a trend toward worse survival in patients with liver metastases and patients in recursive partitioning analysis (RPA) Class II-III versus RPA Class I (P = 0.10 for both; multivariate Cox proportional hazards model analysis). CONCLUSIONS. Approximately 2% of patients with esophageal carcinoma had a diagnosis of brain metastasis. Improved outcome was associated with single brain lesions in patients who underwent surgery and received WBRT. Known liver metastasis and higher RPA scores were associated with a poorer survival trend.
