Not Applicable
Completed
Conditions
Stomach Neoplasms
Interventions
Procedure: Laparoscopic-assisted gastrectomy with D2 lymphadenectomy
Registration Number
NCT02902575
Lead Sponsor
Fujian Medical University
Brief Summary

The purpose of this study is to explore the safety, feasibility, long-term and oncologicaloutcomes of laparoscopic-assisted gastrectomy for advanced Gastric Cancer after neoadjuvant chemotherapy.

Detailed Description

A prospective single-arm study designed to further evaluate laparoscopic-assisted gastrectomy for advanced Gastric Cancer after neoadjuvant chemotherapy will be performed, to evaluate the safety, feasibility, long-term and oncological outcomes. The evaluation parameters are perioperative mobility and mortality, perioperative clinical efficacy, postoperative life quality, immune function and 3-year survival and recurrence rates.
