  • women of childbearing age must have a pregnancy test in 7 days before entering the group (in serum), and the results were negative, and willing to use appropriate contraception during the study period and the last 8 weeks after giving drug test; men should have the surgical sterilization, or adopt the appropriate contraceptive methods during the test and the last 8 weeks after giving drug test#

  • No other clinical studies were conducted before and during the treatment

  • participants is willing to participate in this study, sign the informed consent, have good compliance, cooperate with follow-up.

Exclusion criteria

  • Previous history of chemotherapy, radiotherapy, targeted drug therapy or immunotherapy
  • Patients with contraindications for surgical treatment and chemotherapy or whose physical condition and organ function do not allow for larger abdominal surgery
  • patients with metastasis
  • Having any active autoimmune diseases or a history of autoimmune diseases (such as interstitial pneumonia, uveitis, enteritis, hepatitis, pituitary inflammation, vasculitis, myocarditis, nephritis, hyperthyroidism, hypothyroidism, including but not limited to these diseases or syndromes); Patients with vitiligo or cured childhood asthma/allergies who did not need any intervention in adulthood were excluded; Autoimmune hypothyroidism treated with a stable dose of thyroid replacement hormone; Type 1 diabetes with stable doses of insulin
  • A history of immunodeficiency, including HIV testing positive, or other acquired or congenital immunodeficiency disorders, or a history of organ transplantation and allogeneic bone marrow transplantation
  • Accompanied by serious heart, lung, liver, kidney disease; Have nerve, mental disease; Jaundice or obstruction of the digestive tract with severe infection

  • With # magnitude of coronary heart disease, arrhythmia (including QTc protracted between male > 450 ms, women > 470 ms) and cardiac insufficiency
  • Patients have a clear tendency with gastrointestinal bleeding, including the following situation: local active ulcerative lesions, and fecal occult blood (+ +); with melena and hematemesis history in 2 months; and patients with fecal occult blood (+) and unresected gastric primary tumor; patients with the risk of bleeding should take the gastroscopy test, if it is the gastric cancer, and researchers believe that may results in massive digestive tract hemorrhage#coagulation dysfunction (INR(international normalized ratio)>1.5, APTT(activated partial thromboplastin time)>1.5 ULN), with bleeding tendency;
  • Subjects have failed to control good cardiovascular clinical symptoms or disease, including but not limited to: such as: (1) the NYHA class II heart failure (2) above unstable angina pectoris (3) occurred within 1 year (4) have clinical significance of myocardial infarction (mi) room sex or ventricular arrhythmias without clinical intervention on or after clinical intervention is still poorly controlled
  • History of interstitial lung disease (except radiation pneumonia without hormone therapy), and history of non-infectious pneumonia
  • Patients are positive of urine protein (urine protein detection 2+ or above, or 24 hours urine protein quantitative >1.0g);
  • A person who has previously been allergic to any component of camrilizumab or to any component of the drug under study
  • The researchers consider those who were not suitable for inclusion.

Trial design

585 participants in 2 patient groups

neoadjuvant immunochemotherapy group
Description:
The immune checkpoint inhibitors (ICIs) used for neoadjuvant immunotherapy in this study included sintilimab, nivolumab, and camrelizumab. Neoadjuvant chemotherapy regimens were primarily categorized into two- and three-agent regimens. The two-agent regimens included: SOX (S-1 + oxaliplatin), CapeOx (capecitabine + oxaliplatin), AS (S-1 + nab-paclitaxel), FOLFOX (oxaliplatin + fluorouracil) and DS (S-1 + docetaxel). The three-agent regimens included: FLOT (docetaxel + oxaliplatin + fluorouracil), DOS (docetaxel + oxaliplatin + S-1) and POF (paclitaxel + oxaliplatin + fluorouracil). Dosages were calculated based on drug monographs, guidelines, and patient body surface area. The patients underwent LG within 4-6 weeks after completing neoadjuvant therapy.
