Comparing surgery and radiation for early-stage esophageal cancer
Official title: Adjuvant Esophagectomy Versus Chemoradiation for Patients With Clinical Stage N0 and Pathological Stage T1b (After Endoscopic Submucosal Dissection, ESD) Esophageal Squamous Cell Carcinoma (Ad-ESD Trial): a Multicentric, Open Label, Randomized Trial
Run by Shanghai Chest Hospital · NCT04135664 · Data updated 2026-11-12
This study is testing whether surgery or radiation works better for people with early-stage esophageal cancer to help them live longer and have a better quality of life.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-75 with biopsy-proven esophageal squamous cell carcinoma at clinical N0 and pathological T1b stages.
✕Probably not a fit
Patients with prior treatments for esophageal cancer or other primary tumors, distant metastasis, or those unable to understand informed consent may not benefit from this study.

What this trial studies
This phase III trial aims to compare the effectiveness of esophagectomy versus chemoradiation in patients with clinical stage N0 and pathological stage T1b esophageal squamous cell carcinoma following endoscopic submucosal dissection. It is a multi-center, randomized trial that includes two treatment arms: one receiving esophagectomy and the other receiving chemoradiation. Additionally, there is a registry arm for patients and surgeons who prefer not to be randomized. The primary goal is to assess the 5-year overall survival rate between the two treatment options, while secondary outcomes include quality of life and relapse-free survival rates.
Why it matters
Potential benefit: If successful, this trial could provide a less invasive treatment option with improved quality of life for patients with early-stage esophageal cancer.
How similar studies have gone: Previous studies have indicated promising outcomes for chemoradiation in similar patient populations, but this specific comparison in a phase III setting is novel.
