Overview

To evaluate the clinical efficacy of camrelizumab, apatinib Mesylate and nab-paclitaxel combined with oxplatin and S-1 in the neoadjuvant treatment of locally advanced gastric cancer with different genotypes

Interventions

• Drug Camrelizumab
  Camrelizumab One course will last 21 days. Given once every 3 weeks at a dose of 200 mg.
