Minimally invasive techniques, especially robotic surgery, yield better results for gastric cancer patients.

• Textbook outcome achieved in 31.4% of open cases, 56.8% of laparoscopic, and 68.6% of robotic.
• Hospital stays were shorter for laparoscopic and robotic procedures.

Achieving a textbook outcome is linked to improved 1-year survival rates across all techniques.

• Robotic gastrectomy showed superior oncological resection with a higher R0 rate.
