Three-field vs two-field lymphadenectomy in thoracic ESCC patients: a multicenter randomized study (NST 1503).

ABSTRACT:

Background

3-field lymph node dissection (3FL) frequently lead to much more perioperative complications than 2-field lymph node dissection (2FL). This study was designed as a non-inferiority trial to evaluate whether 3FL could be omitted without compromising overall survival (OS) and disease-free survival (DFS) in the patients with resectable thoracic esophageal squamous cell cancer (ESCC) and negative right recurrent laryngeal nerve lymph nodes (RRLN-LNs).

Methods

cT1b-3N0-1M0 thoracic ESCC patients were managed in 3 arms during open or minimally invasive McKeown esophagectomy according to the results of frozen section examination for RRLN-LNs: if positive, direct 3FL (RRLN[+]-3FL); if negative, 2FL (RRLN[-]-2FL) or 3FL (RRLN[-]-3FL) by randomization.
