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.
