Comparison of Esophagectomy and Chemoradiation for Patients With cN0-pT1b Stage Esophageal Squamous Cell Carcinoma

2019-10-28 13:57:15 | BioPortfolio


The ad-ESD trial is phase III randomized trial to compare adjuvant esophagectomy and chemoradiation for patients with clinical stage N0 and pathological stage T1b squamous cell carcinoma (after endoscopic submucosal dissection).


Esophagectomy is still the primary treatment for pathological T1b esophageal squamous cell carcinoma. However, esophagectomy is associated with high mortality and morbidity and decreased quality of life. Endoscopic resection followed with chemoradiation had showed uncompromised oncological outcomes with esophagectomy. But there is no well-designed, phase III trial to compare the two treatment for patients with pT1b squamous cell carcinoma.

The ad-ESD trial is a multi-center prospective superiority trial, combied of a randomized clinical trial and a prospective registry.

The experimental design produces two randomized arms; (1) esophagectomy and (2) chemoradiation. An additional registry arm will be based on surgeons/patients that do not want to be randomised because of their own experience on adjuvant therapy, including esophagectomy; chemoradiation and active surveillance.

The primary endpoint is to evaluate the difference of 5-year overall survival rate between definitive chemoradiation and esophagectomy, in patients with cN0-pT1b esophageal squamous cell cancer (ESCC) after endoscopic resection.

The secondary endpoints are to evaluate the difference of quality of life and oncological outcomes including 3-year overall survival (OS) and 3, 5-year relapse free survival (RFS) between the two treatments.

Medical and Biotech [MESH] Definitions

A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions.
