Detailed description: To investigate the effect of Terelizumab (aka Tislelizumab) combined with XELOX in Neoadjuvant Therapy for gastrointestinal tumors.

To explore new biomarkers that can predict the efficacy of combined immunotherapy, and to establish a clinical efficacy prediction model by means of bioinformatics to prospectively judge the efficacy and guide the follow-up individualized and accurate treatment.

In this program, women of childbearing age are defined as sexually mature women:

However, the patients who met the following requirements and had measurable lesions outside the central nervous system were allowed to enter the group: asymptomatic after treatment, imaging was stable for at least 4 weeks before the start of treatment (such as no new or enlarged brain metastases). And systemic corticosteroids and anticonvulsant drugs have been stopped for at least 2 weeks.

* There are pleural effusion with clinical symptoms, pericardial effusion or ascites requiring frequent drainage (≥ 1 / month).
