FLOT combined with PD-1

EXPERIMENTAL

The enrolled patients will receive 4 cycles of FLOT regimen + teriprizumab treatment before surgery Q2W. If the transformation is successful, the patient undergoes R0 surgical resection of D2 lymph node dissection, and will continue to receive 4 cycles of FLOT regimen + Teripril after surgery. Anti-treatment, the treatment plan is the same as before. After completing the 4 cycles of treatment, oral Tiggio Capsule (S-1) and Teriprizumab were maintained for 1 year.
