Clinical Efficacy and Safety of Tirelizumab Combined With Chemotherapy in the Treatment of HER-2 Negative Locally Advanced Resectable Gastric Cancer
This study objectively analyzes the safety and survival evaluation of perioperative immunotherapy combined with chemotherapy in locally advanced gastric cancer patients through a prospective randomized controlled trial research method; By comparing the pathological response rate, disease-free survival rate, and incidence of adverse events between the combination therapy and chemotherapy alone group, we aim to verify the efficacy and safety of tirelizumab combined with SOX/XELOX chemotherapy in disease control of locally advanced gastric cancer patients, laying the foundation and providing a basis for large-scale multicenter clinical research.
• The subjects voluntarily joined this study and signed an informed consent form
• Locally advanced gastric or gastroesophageal junction adenocarcinoma confirmed by pathology or histology as HER-2 negative (cT2-4N+M0 Phase II-III)
• The primary lesion can be surgically removed, and the patient is willing to receive surgical treatment
• There are measurable solid tumors (efficacy evaluation standard: RECIST 1.1)
• Tumor evaluation should be conducted through CT scanning or MRI within 28 days before treatment
• ECOG score 0-1
• Life expectancy ≥ 12 months.
