Abstract

Purpose: The role of non-surgical treatments (NS), such as chemoradiotherapy or radiotherapy, for clinical T1N0M0 esophageal cancer (cT1N0M0 EC) has not been well delineated. The aim of this study was to evaluate and compare the feasibility and efficacy of NS and Surgical treatment (S) in cT1N0M0 EC patients. Methods: The medical records of patients who received treatment for cT1N0M0 EC at Asan Medical Center between2003 and 2012 were retrospectively reviewed. The baseline characteristics, treatment outcomes and complications, and survival were compared. Results: There were 264 S and 20 NS patients with respective median ages of 69.5 and 63.0. The main histologic finding was squamous cell carcinoma in both groups (97 and 100 %, respectively). The Eastern Cooperative Oncology Group performance status and Charlson comorbidity index score were poorer in the NS group. With a median follow-up of 49.0 months, 37 S patients (14 %) and 3 NS patients (15 %) exhibited recurrence. The first sites of recurrence for S and NS patients were locoregional (21 vs. 3 patients), distant (6 vs. 0), and both locoregional and distant (9 vs. 0), respectively. The median time-to-recurrence could not be calculated in either group (log-rank test P = 0.831). The estimated median overall survival was 64.4 months (95 % CI 37.2-91.6 months) in the NS group and could not be calculated in the S group (P = 0.056). Conclusions: Non-surgical treatments can be an effective alternative to S for patients with cT1N0M0 EC unfit for radical surgery. The role of NS for early stage EC needs to be further verified with prospective randomized trials.
