Background
Despite the increased risk for nodal disease, definitive endoscopic resection is being increasingly offered for lesions invasive into the submucosa based on the success with intramucosal tumors. The aim of this study was to evaluate survival after esophagectomy alone for confirmed submucosal tumors after endoscopic resection.
Methods
Patients from seven centers in the USA who underwent esophagectomy for submucosal tumors removed with endoscopic resection were analyzed. Nodal involvement was correlated with recurrence and survival.
Results
We identified 23 patients with submucosal esophageal adenocarcinoma. Esophagectomy was performed at a median of 2 months (Interquartile range 1–3) after the endoscopic resection. There was no postoperative mortality. Positive nodal disease was seen in 26 % of patients on final pathology. At a median of 37 months (Interquartile range 25–55), 91 % of patients were alive and free of disease. The disease-specific 5-year survival was 88 %. Disease-specific 5-year survival was 67 % in patients with positive nodal metastases and 100 % in those without (p = 0.159).
Conclusions
Esophagectomy is curative in the majority of patients with submucosal tumors even in the presence of nodal metastases. These data serve as a benchmark for comparison when considering extending the indications for therapeutic endoscopic resection for submucosal tumors in the future.
