Laparoscopic versus open distal gastrectomy with D2 lymphadenectomy following neoadjuvant chemotherapy for locally advanced gastric cancer (CLASS-03b): protocol for a multicentre, randomised, controlled, non-inferiority trial.

ABSTRACT:

Introduction

Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide, with most Chinese patients diagnosed at a locally advanced stage. Neoadjuvant chemotherapy (NAC) is increasingly used to improve resectability and survival. Laparoscopy-assisted distal gastrectomy (LADG) provides short-term recovery benefits compared with open distal gastrectomy (ODG), but its safety and oncologic efficacy following NAC remain uncertain. This trial aims to determine whether LADG is non-inferior to ODG in terms of long-term survival outcomes in patients with locally advanced distal gastric cancer (LAGC) after NAC.

Methods and analysis

This is a multicentre, randomised, controlled, non-inferiority trial conducted at high-volume GC centres in China. Eligible patients
