Brief summary: The purpose of this study is to analyze esophageal cancer patients who underwent neoadjuvant immunotherapy with chemotherapy followed by esophagectomy to determine whether additional adjuvant therapy is associated with improved survival outcomes.

Detailed description: Eligiled patients with pathologically confirmed thoracic esophageal squamous cell carcinoma and at clinical T1b-3N1-3M0 or T3N0M0 according to the eighth edition of American Joint Committee on Cancer staging will be allocated to neoadjuvant immunotherapy (tislelizumab 200mg d1, q3w × 2 cycles ) and chemotherapy (nad-paclitaxel 260 mg/m2 d1 + carboplatin AUC = 5 d1, q3w × 2 cycles) treatment. Patients with resected (R0) were assigned to receive tislelizumab ( at a dose of 200 mg every 3 weeks for 30 weeks) in pCR patients or adjuvant immunotherapy and chemothearpy for two cycles, and then tislelizumab ( at a dose of 200 mg every 3 weeks for 24 weeks) in non-pCR patients.The primary endpoint for this study is 2-year disease-free survival (DFS) in non-pCR patients.The secondary endpoints include pCR rate, major pathological response (MPR) rate, 2-year DFS in pCR patients, R0 resection rate, adverse events, and overall survival (OS).

Eligibility criteria: Inclusion Criteria:

1. The patient volunteers to participate in the study, signs a consent form, has good compliance, and obeys the follow-up, and is willing and able to follow the protocol during the study;

13. Fertile female subjects are required to have a negative serum or urine pregnancy test no later than 72 hours before starting the study drug administration, and to use effective contraception (such as an IUD, contraceptive pill, or condom) during the trial period and for at least 3 months after the last dose; For male subjects whose partners are women of reproductive age, effective contraception should be used during the trial period and within 3 months after the last dose.

Exclusion Criteria:

1. Unresectable factors, including those who are unresectable for tumor reasons or have surgical contraindications, or who refuse surgery;
2. Patients with supraclavicular lymph node metastasis;
3. Poor nutritional status, BMI\<18.5Kg/m2; Patients could continue to be considered for enrollment if corrected with symptomatic nutritional support before enrollment and after assessment by the principal investigator
4. Allergy to any drugs;
5. Have received or are receiving any of the following treatments; a) any radiotherapy, chemotherapy or other antineoplastic drugs directed at the tumour; b) being treated with an immunosuppressive drug or systemic hormone for immunosuppression (at a dose of \>10mg/ day of prednisone or equivalent) within 2 weeks before the first dose of the study drug; Inhaled or topical steroids and corticosteroid replacement at doses \>10mg/ day of prednisone or equivalent were allowed in the absence of active autoimmune disease; c) received live attenuated vaccine within 4 weeks before the first dose of study drug; d) major surgery or severe trauma within 4 weeks before the first dose of study drug;
6. Human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) active infection or known HIV seropositivity; including HBV or HCV surface antigen positive (RNA)
7. Uncontrolled cardiac symptoms or diseases, including but not limited to: (1) heart failure above NYHA class II, (2) unstable angina, (3) myocardial infarction within 1 year, (4) clinically significant supraventricular or ventricular arrhythmias without or poorly controlled after clinical intervention;
8. Severe infection (CTCAE\>2) occurred within 4 weeks before the first dose of study drug, such as severe pneumonia requiring hospitalization, bacteremia, and infectious complications; Prophylactic antibiotics were excluded if there was active pulmonary inflammation on chest imaging at baseline, if there were signs and symptoms of infection within 14 days before the first dose of the study drug, or if treatment with oral or intravenous antibiotics was required
9. Participation in other drug clinical studies within 4 weeks before randomization;
10. Patients with interstitial pneumonia or interstitial lung disease, or previous history of interstitial pneumonia or interstitial lung disease requiring hormone therapy, or other subjects with pulmonary fibrosis, organized pneumonia (such as bronchiolitis obliterans), pneumoconiosis, drug-related pneumonia, idiopathic pneumonia that may interfere with the judgment and treatment of immune related pulmonary toxicity, or subjects with active pneumonia or severe lung function damage revealed by CT during screening; Active pulmonary tuberculosis;
11. Patients with any active autoimmune disease or history of autoimmune disease and possible recurrence \[including but not limited to autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism (patients who can be controlled only by hormone replacement therapy can be enrolled)\]; Patients with skin diseases that do not require systemic treatment, such as leukoplakia, psoriasis, alopecia, patients with type I diabetes that can be controlled by insulin treatment, or patients with a history of asthma, but have completely relieved in childhood and do not need any intervention, can be enrolled; Asthma patients who needed bronchodilators for intervention could not be enrolled; Patients have previously received an anti-PD-1，PD-L1 or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways;
12. Other malignancies that had been diagnosed within 5 years before the first dose of a study drug were considered unless cancers with a low risk of metastasis or death (5-year survival rate, \>90%), such as adequately treated basal-cell or squamous-cell skin cancer or carcinoma in situ of the cervix, were considered.
13. Pregnant or lactating women;
14. The investigators determined that there were other factors that might have led to the forced discontinuation of the study, such as other serious medical conditions (including mental illness) requiring co-treatment, alcohol, substance abuse, family or social factors, and factors that might have affected the safety or adherence of the subjects.
