  • Patients voluntarily enrolled in this study and signed informed consent forms;
  • Age 18-75 years;
  • Pathologically confirmed gastric adenocarcinoma or gastroesophageal junction adenocarcinoma;
  • MHC-II negative, with <5% tumour cells displaying staining <2+ (grade 2 or stronger);
  • Clinically staged as cT3-4aN+M0 gastric or gastroesophageal junction adenocarcinoma confirmed by CT and/or laparoscopy (per AJCC 8th Edition staging);
  • No prior antineoplastic therapy for current disease (e.g., surgery, radiotherapy, chemotherapy, targeted therapy, immunotherapy);
  • Scheduled for surgical intervention following completion of neoadjuvant therapy;
  • Able to swallow tablets orally;
  • ECOG performance status 0-1;
  • Expected survival ≥6 months.

排除标准

  • Known signs of active bleeding from a lesion.
  • Patients with known dMMR/MSI-H status.
  • Oesophageal or pyloric near-obstruction affecting the subject's ability to eat or gastric emptying, or difficulty swallowing tablets.
  • Subjects with unresolved Grade >1 toxicity related to any prior antineoplastic therapy (excluding persistent Grade 2 alopecia, anaemia, peripheral neuropathy, electrolyte abnormalities correctable with treatment, or endocrine abnormalities controlled and stable with hormone replacement therapy).
  • Known dihydropyrimidine dehydrogenase (DPD) deficiency (or prior fluorouracil-containing therapy resulting in Grade 3 or higher mucositis).
  • Known hypersensitivity to any monoclonal antibody or component of the chemotherapy agents (capecitabine, oxaliplatin) (resulting in Grade 3 or higher hypersensitivity reaction).
