Brief summary
To evaluate the clinical efficacy (safety, feasibility and long-term efficacy) of robotic radical total gastrectomy and laparoscopic radical total gastrectomy in patients with locally advanced middle and upper gastric adenocarcinoma (CT2-4A, N-/+, M0) .
Detailed description
In the field of gastrectomy, Hashizume et al. first reported robotic gastrectomy in 2002. Since then, reports on the safety and feasibility of the application of robotic surgical system in the treatment of gastric cancer (GC) have gradually increased. Reports of robotic surgery for GC are increasing, especially in Asia. Several studies confirmed the advantages of robotic gastrectomy when compared with laparoscopic gastrectomy. However, whether robotic radical total gastrectomy is noninferior to laparoscopic radical total gastrectomy remains unclear. The investigator first carried out this study in the world to evaluate the efficacy of robotic radical total gastrectomy versus laparoscopic radical total gastrectomy for GC.
Interventions
PROCEDURERobotic radical total gastrectomy with D2 lymphadenectomy
Most surgical procedures are performed using the robot system.
PROCEDURELaparoscopic radical total gastrectomy with D2 lymphadenectomy
Without the robot system, Most surgical procedures are performed using laparoscopic equipment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 3-year disease free survival rate | 36 months | 3-year disease free survival rate |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 3-year overall survival rate | 36 months | 3-year overall survival rate |
| 3-year recurrence pattern | 36 months | Recurrence patterns are classified into five categories at the time of first diagnosis: locoregional, hematogenous, peritoneal, distant lymph node, and mixed type. |
| intraoperative morbidity rates | 1 day | The intraoperative postoperative morbidity rates are defined as the rates of event observed within operation. |
| overall postoperative serious morbidity rates | 30 days | Refers to the incidence of early postoperative complication which is graded as Clavien-Dindo IIIA or higher |
| Morbidity rates | 30 days | This is for the early postoperative complication, which defined as the event observed within 30 days after surgery. |
| postoperative recovery course | 30 days | Duration of postoperative hospital stay in days is used to assess the postoperative recovery course. |
| postoperative nutritional status | 3, 6, 9 and 12 months | The variation of weight on postoperative 3, 6, 9 and 12 months are used to access the postoperative nutritional status. |
| inflammatory immune response | Preoperative 3 days and postoperative 1, 3, and 5 days | The variation of white blood cell count from peripheral blood before operation and on postoperative day 1, 3, 5 are recorded to access the inflammatory and immune response |
| Total Number of Retrieved Lymph Nodes | 1 day | Total Number of Retrieved Lymph Nodes |
