Such as: esophageal perforation and active esophageal bleeding, obvious trachea, thoracic large blood vessel invasion； According to the surgeon's assessment, the total lung function can withstand the proposed esophageal cancer resection；
• Age and reproductive status Age ≥18 years old and ≤75 years old； Females of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity of 25 IU/L or equivalent for HCG) within 24 hours prior to initiation of study treatment； Women must be non-nursing；

You may not qualify if…

• Medical condition There is locally advanced unresectable (regardless of stage) or metastatic disease.
• Participants with Grade ≥2 Peripheral Neuropathy； Participants with active, known or suspected autoimmune disease. Participants with type 1 diabetes, hypothyroidism requiring only hormone replacement therapy, skin disorders that do not require systemic treatment (eg, vitiligo, psoriasis, or alopecia), or disorders that are not expected to recur in the absence of external stimuli are eligible to be enrolled； Participants requiring systemic therapy with glucocorticoids (>10 mg prednisone equivalent daily) or other immuno suppressive drugs within 14 days prior to treatment. In the absence of active autoimmune disease, inhaled or topical steroids and adrenal hormone replacement therapy at >10 mg prednisone-equivalent daily are permitted； Known history of positive human immuno deficiency virus (HIV) test or known acquired immuno deficiency syndrome (AIDS)； Participants with serious or uncontrolled medical illness； previous/concomitant therapy； Received chest radiotherapy, chemotherapy, immunotherapy, or surgery of the esophagus, esophagus and gastric junction, or stomach prior to the start of the trial.
• Patients with severe cardiovascular or pulmonary disease, interstitial pneumonia, or previous history of interstitial pneumonia； Patients with obvious esophageal ulcers, moderate pain in the chest and back, and esophageal perforation symptoms； Physical examination and laboratory test results
• Laboratory screening values must meet the following criteria (using CTCAE 4th edition):
• i) WBC < 2000/μL； ii) Neutrophils < 1500/μL； iii) Platelets < 100x103/μL； iv) Hemoglobin < 9.0 g/dL； v) Serum creatinine <1.5 x ULN or calculated creatinine clearance (CrCl) < 50 mL/min (using Cockcroft-Gault formula)； vi) AST >3.0 x ULN； vii) ALT > 3.0 x ULN； viii) Total bilirubin >1.5 x ULN (except for Gilbert syndrome participants, who had total bilirubin < 3.0 x ULN)； Participants had active hepatitis B (positive for hepatitis B surface antigen [HBsAg] or positive for hepatitis C virus (HCV) (positive for HCV RNA)； i) Participants with previous or recovered HBV infection (defined as having hepatitis B core antibody [HBcAb] and no HBsAg) are eligible. HBV DNA from these patients must be obtained prior to treatment. Participants who are HBV carriers or require antiviral therapy are not eligible； ii) Participants positive for HCV antibodies are eligible only if PCR for HCV RNA is negative.； Active malignancy within the past 3 years, except for locally curable cancers that have been significantly cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast； Participants with serious or uncontrolled medical conditions； Allergic Reactions and Adverse Drug Reactions； History of allergic reactions or hypersensitivity reactions to study drug components Other exclusion criteria； Patients who do not understand trial requirements, or who may not comply with trial requirements； Active infection requiring systemic therapy 14 days prior to first dose Some obvious diseases that the researchers believe should be excluded from this study；
