• Stomach Neoplasms

Intervention

Drug:
• sintilimab
a checkpoint inhibitor via blocking PD-1 (programmed cell death-1) site of signaling.
• apatinib
a multi-target anti-angiogenic tyrosine kinase inhibitor (TKI)
• S1
S-1 is an oral fluoropyrimidine consisting of tegafur (a prodrug that is converted to fluorouracil, mainly in liver microsomes but also in tumour tissue), gimeracil (an inhibitor of dihydropyrimidine dehydrogenase, which degrades 5-FU), and oteracil (which inhibits the phosphorylation of 5-FU in the gastrointestinal tract, thereby reducing the toxic effects of 5-FU in the intestinum).
• Nab paclitaxel
Nab paclitaxel is a albumin-bound well tolerated paclitaxel than traditional paclitaxel

(near CR), single cells or rare small groups of cancer cells; 2. (PR), residual cancer cells with evident tumor regression but more than single cells or rare small groups of cancer cells; and 3. (poor or no response), extensive residual cancer with no evident tumor regression.	up to one year after surgery
