Brief summary
The goal of this observational study is to learn about the long-term effect of surgery in metastatic gastric cancer patients who are accessed as having opportunity for surgery under Multi-disciplinary Team (MDT) evaluation. The main question it aims to answer is: Does surgery extend survival time in metastatic gastric cancer patients who are accessed as having opportunity for surgery under Multi-disciplinary Team (MDT) evaluation?
Detailed description
Select metastatic gastric cancer patients that have the opportunity to undergo any forms of surgery through MDT. Then further evaluate these patients' risks and benefits. Let patients make their finally decision through shared-decision making (SDM). According to the actual decision, the patients are divided into surgery group and non-surgery group.
