Arms & Interventions
Tislelizumab plus Chemotherapy
In the single experimental arm, patients with locally nonresectable disease were subjected to receive neoadjuvant tislelizumab (200mg) plus chemotherapy (FP regimen) for conversion therapy. If conversion therapy succeeds, patients would proceed to surgery and adjuvant therapy. Otherwise, if patients were still not resectable after the conversion therapy, they will be treated by tislelizumab plus chemotherapy with or without palliative radiotherapy .
Intervention: Tislelizumab
Tislelizumab plus Chemotherapy

If conversion therapy succeeds, patients would proceed to surgery and adjuvant therapy. Otherwise, if patients were still not resectable after the conversion therapy, they will be treated by tislelizumab plus chemotherapy with or without palliative radiotherapy .
Intervention: 5-FU

Outcomes
Primary Outcomes
Incidence of translational treatment AE
Time Frame: up to 2 years
Translational treatment-related AEs resulted in rates of surgery that were more than 30 days late or inoperable than originally planned
MPR
Time Frame: up to 2 years
The proportion of patients whose primary tumor cell residual was less than 10% in the total number of patients enrolled after transformation therapy
pCR
Time Frame: up to 2 years
Pathological complete response refers to that no tumor component or a small amount of carcinoma in situ component can be found on the horizontal line of pathological section after systemic treatment and surgical resection of the lesion.
Secondary Outcomes
- Disease-free Survival，DFS(up to 2 years)
- R0 resection rate(up to 2 years)
