Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	PCR rate	Pathological response were classified into three grades.Grade I signifies that there is little shrinkage in the tumor; only mild regression in the tumor cells is observed under telemicroscope. Grade II shows gross reduction in size of the tumor and marked regression in the cancer cells microscopically, yet viable nests of cancer tissue are still visible. Grade III implies complete or almost total resolution of the tumor on exploration, and disappearance of the tumor tissue microscopically; only remnants of degenerated cancer cells can be seen (so-called ghost cancer cells).	6-8 months
Secondary	Acute chemotherapy/Chemoradiotherapy toxicities	chemotherapy toxicities are evaluated by NCI-CTC version 4.0 and radiotherapy toxicities are graded using the RTOG/EORTC Radiation Morbidity Scoring Schema.	6-8 months
Secondary	surgery complications	During hospital stay and within the first 30 days after completion of surgery.	6-8 months
Secondary	Tumor down-staging	Down-staging was considered as any stage reduction between clinical and pathologic stage.	6-8 months
Secondary	R0 resection rate	The surgical procedure was total or subtotal gastrectomy with recommended D2 lymphadenectomy 4-6 weeks after total neoadjuvant therapy.	6-8 months
