Multicenter Study on Laparoscopic Total Gastrectomy for Advanced Gastric Cancer

Prospective Randomized Controlled Multicenter Clinical Trial For Comparison Of Long-term Outcomes Between Laparoscopic And Open Total Gastrectomy In Patients With Locally Advanced Gastric Cancer

Sponsor

Shanghai Zhongshan Hospital

Enrollment

1,018 participants

Start Date

Jan 20, 2021

Study Type

INTERVENTIONAL

Conditions

Stomach Neoplasms

Summary

CLASS-07 trial is a prospective, multicenter, randomized controlled trial for comparison of long-term outcomes between laparoscopic total gastrectomy (LTG) and open total gastrectomy (OTG) in patients with locally advanced gastric cancer (clinical stage T2-4aN0-3M0). The primary purpose of this study is to evaluate the overall survival and determine the efficacy of LTG compared with OTG for locally advanced gastric cancer. The second purpose is to evaluate the 3-year overall survival rate, 3-year disease free survival rate, morbidity and mortality rates, 3-year recurrence pattern and postoperative recovery course of the patients enrolled in this study.
