Feasibility Study of Laparoscopy-assisted D2 Distal Gastrectomy to Treat Advanced Gastric Cancer (COACT_1001)

October 5, 2015 updated by: Young-Woo Kim, National Cancer Center, Korea

A Multicenter Randomized Phase II Clinical Trial of Laparoscopy Assisted Versus Open Distal Gastrectomy With D2 Lymph Node Dissection for Advanced Gastric Cancer

The purpose of this study is to evaluate the oncological feasibility of laparoscopy-assisted distal gastrectomy with D2 lymph node dissection for advanced gastric cancer.

Study Overview

Status

Unknown

Conditions

Intervention / Treatment

Detailed Description

To test oncological feasibility, compliance of nodal dissection was selected as a primary end point. When there are more than two missing nodal station(no lymph nodes in dissected area), it is defined as a non-compliant nodal dissection. Other secondary outcomes will be supplementary to evaluate feasibility of D2 dissection.
