Brief summary: The objective of this study is to evaluate the efficacy and safety of concurrent chemoradiotherapy combined with immunotherapy in patients with potentially resectable pancreatic cancer.

Detailed description: Due to the hidden onset and rapid progression of pancreatic cancer, most patients are already locally advanced or have distant metastasis at the time of diagnosis and lose the opportunity for surgery. Even among operable patients, about 50% will have recurrence and metastasis one year after surgery. Therefore, more and more evidence supports neoadjuvant therapy for patients with high risk factors for resectable pancreatic cancer, and conversion therapy followed by surgery for patients with borderline resectable and locally advanced pancreatic cancer. Therefore, the objective of this study is to evaluate the efficacy and safety of concurrent chemoradiotherapy combined with immunotherapy in patients with potentially resectable pancreatic cancer.

Eligibility criteria: Inclusion Criteria:

1. Age \>= 18 years； 2. Eastern Cooperative Oncology Group (ECOG) score of 0-1; 2. Pancreatic cancer confirmed by histology or cytology; 3. Potentially resectable pancreatic cancer documented by contrast enhanced CT (or MRI) scan; 4. Hematological indexes: Neutrophil count \>= 1.5 x 10\^9/L Hemoglobin \>= 10g / dl Platelet count \>= 100 x 10\^9 / L 5. Biochemical indicators: Total bilirubin \<= 1.5 x upper limit of normal value (ULN); Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) \< 1.5 x ULN; Creatinine clearance rate \>= 60ml / min.

6. Participants of childbearing age need to take appropriate protective measures (contraceptive measures or other methods of birth control) before entering the group and during the test: 7. Signed informed consent; 8. Follow the protocol and follow-up procedures.

Exclusion Criteria:

1. Have received systematic anti-tumor treatment.
2. Previous history of other tumors, except for cervical cancer in situ, treated squamous cell carcinoma or bladder epithelial tumor (TA and TIS) or other malignant tumors that have received radical treatment (at least 5 years before enrollment).

6. Pregnant and lactating women. Pregnant women of childbearing age must be tested negative within 7 days before entering the group.
7. Drug abuse, clinical or psychological or social factors make informed consent or research implementation affected.
8. Allergic to programmed cell death protein-1 (PD-1) monoclonal antibody immunotherapy drugs.
