4536 Background: Neoadjuvant chemotherapy has been demonstrated to improve the pathological complete response(pCR) and 5-year survival rate of patients with locally advanced gastric and gastroesophageal junction adenocarcinoma (GC/GEJC). Immunotherapy has become a new promising treatment for advanced GC/GEJC. Therefore, we intended to evaluate the safety and efficacy of Camrelizumab (anti-PD-1 antibody) combined with FOLFOX as the neoadjuvant therapy for patients with locally advanced GC/GEJC. Methods: Eligiblepatients were locally advanced GC/GEJC with clinical stage≥T2 and/or positive lymphoglandula confirmed by endoscopic ultrasonography (EUS) and imaging. They received 4 cycles neoadjuvant therapy which including Camrelizumab(200mg ivgtt D1), FOLFOX(Oxaliplatin 85mg/m 2 ivgtt D1, 5-Fu 400mg/m 2 iv D1, LV 200mg/m 2 ivgtt D1, 5-Fu 2.4mg/m 2 CIV 46 hours) every 14 days. Imaging evaluation was performed in 2-4 weeks after neoadjuvant therapy. Patients without progression disease (PD) received D2 radical gastrectomy. The primary endpoint was pCR, the secondary endpoints were R0 resection rate and safety. Results: From July 24 2019 to January 31 2020, 16 patients were eligible. The median age was 57 years (29-72 years). A total of 11(69%) males and 5(31%) females, ECOG PS 0 (n=9, 56%), ECOG PS 1 (n=7, 44%). All the patients completed 4 cycles treatment and none of them was confirmed PD by image. One of the patients refused gastrectomy and withdraw from the study. The other 15 p...
