How to handle brain tumors after esophagectomy with curative intent: A single center 20-year experience

In total, 2131 patients underwent esophagectomy with curative intent, of which 72 patients (3.4%) developed BT. Pathological diagnosis was obtained in 26 patients (1.2%), of which 2 patients were diagnosed with glioblastoma. On multivariate analysis, radiotherapy (OR, 7.71; 95%CI: 2.66-22.34, p < 0.001) was associated with an increased risk of BT and early-stage tumors (OR, 0.29; 95%CI: 0.10-0.90, p = 0.004) with a decreased risk of BT. Median overall survival was 7.4 months (95%CI: 4.80-9.96). BT treated with curative intent (surgery or stereotactic radiation) had a significantly better median overall survival (16 months; 95%CI: 11.3-20.7) compared to those without (3.7 months; 95%CI: 0.9-6.6, p < 0.001) CONCLUSIONS: Advanced stage tumors and radiotherapy seem related to the development of brain tumors after esophagectomy with curative intent. However, an important diagnostic uncertainty remains in these patients as pathological diagnosis is only obtained in a minority of cases. Tissue confirmation can be useful to inform a patient-tailored multimodality treatment strategy in select patient.
