The purpose of the study is to evaluate the maximal cycle of effective neoadjuvant chemotherapy for resectable gastric cancer, to determine what is the best cycle of neoadjuvant chemotherapy for the patients who receive neoadjuvant chemotherapy.
The study is a non-randomized clinical trial. The protocol has been approved by the Ethics Committee of Beijing Cancer Hospital. MRI and enhanced CT are used to evaluate the clinical response of the tumor. The primary endpoint is the maximal cycle of effective neoadjuvant chemotherapy for resectable gastric cancer.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| experiment group | Experimental | Neoadjuvant chemotherapy(NACT) are performed for locally advanced gastric cancer. The clinical response is evaluated by MRI and enhanced CT. The cycle of neoadjuvant chemotherapy is decided by the doctor and the patents together with shared decision making(SDM). Radical gastrectomy with D2 lymph node dissection are performed after neoadjuvant chemotherapy. Adjuvant chemotherapy(ACT) are preformed after surgery. Questionnaires are preformed to evaluate the involvement emotion and reason for the decision of stopping neoadjuvant chemotherapy. |
