Abstract

Background: After esophagectomy for esophageal carcinoma, 2-13% of patients develop brain metastases (BM) which are associated with a poor prognosis. Further investigation into treatment and prognosis is beneficial given the limited available literature and varying outcomes.

Methods: Case files of all 339 patients who underwent minimally invasive esophagectomy (MIE) in a single high-volume center between January 2015 and December 2020 were retrospectively reviewed. Patients with BM and isolated brain metastases (iBM) were identified and a survival analysis was performed.

Results: Fifteen out of 339 patients (4,4%) undergoing MIE developed BM of which 9 (60,0%) had iBM. Most patients were diagnosed with squamous cell carcinoma (55,6%), localized in the middle third of the esophagus (66,7%), and had a pathologic complete response (66,7%) after initial treatment. Treatment of iBM consisted of gamma knife (GK) radiosurgery (44,4%), surgical resection (22,2%), GK and surgical resection (11,1%), and best supportive care (22,2%). Median time to diagnose iBM was 8,4 months (range 0,2-37,5) and survival after detection of iBM was 14,3 months (95% CI 0,0-45.9). The 2-year survival rate after detection of iBM was 44,4%.

Conclusions: iBM after esophagectomy for esophageal carcinoma is rare, but when encountered can and should be treated with a curative intent in selected cases in close collaboration with large neurosurgical centers. A large-scale study should be conducted to confirm our findings.
