Eligibility Criteria:
Inclusion Criteria:
1. Aged 18 years or order.
2. Diagnosed with locally advanced or early stage esophageal squamous cell carcinoma by pathological examinations of the primary lesion and imaging examinations, which are not resectable.
3. Confirmed to be unresectable and unable to tolerate synchronous chemoradiotherapy by multidisciplinary consultation, and has not undergone systemic drug therapy in the past.
4. PD-L1 tumor proportion score or combined positive score of ≥1%.
5. At least one measurable lesion on imaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
6. An Eastern Cooperative Oncology Group (ECOG) performance status score of 0 -2.
7. Expected survival time of more than three months.
8. Adequate organ function defined as the following laboratory indicators:
1. Absolute neutrophil count (ANC) ≥ 1.5×109/L without use of granulocyte colony-stimulating factor in the past 14 days.
2. Platelet count ≥ 100×109/L without blood transfusion in the past 14 days.
3. Hemoglobin \> 9g/dL without blood transfusion or use of erythropoietin-stimulating agents in the past 14 days.
4. Total bilirubin ≤ 1.5×upper limit of normal (ULN).
5. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5×ULN.
6. Creatinine ≤ 1.5×ULN and creatinine clearance calculated using the Cockcroft-Gault formula) ≥ 60 ml/min.
7. Good coagulation function, defined as an international normalized ratio (INR) or prothrombin time (PT) ≤ 1.5×ULN.
8. Normal thyroid function, defined as thyroid-stimulating hormone (TSH) within the normal range. If the baseline TSH is outside the normal range, subjects with total T3 (or FT3) and FT4 within the normal range can still be included.
9. Normal cardiac enzyme spectrum (or clinically insignificant laboratory abnormalities as determined by the investigator)
9. Negative pregnancy test (urine or serum) within 3 days before the first dose of study drug for female subjects of childbearing potential. If the urine pregnancy test cannot be confirmed as negative, a blood pregnancy test is required. Non-childbearing potential female is defined as postmenopausal for at least 1 year or has undergone surgical sterilization or hysterectomy.
10. Willing to sign the informed consent form.
Exclusion Criteria:
Subjects with any of the following conditions cannot participate in the study:
1. A high risk of bleeding or perforation due to clear invasion of adjacent organs (large arteries or trachea) by the tumor, or with fistula.
2. Diagnosed with malignancies other than esophageal cancer within 3 years prior to the first dose (excluding cured basal cell carcinoma or squamous cell carcinoma of the skin and/or radically resected carcinoma in situ).
3. Previous immunological or immunomodulatory drugs as systemic whole-body treatment, including thymic peptides, interferon, interleukins, except for local use to control pleural effusion.
4. Previous chest radiotherapy.
5. A history of allogeneic organ transplantation (except for corneal transplantation) or allogeneic hematopoietic stem cell transplantation.
6. Allergic to the study drug, Sintilimab, or its excipients.
7. A history of human immunodeficiency virus (HIV) infection (i.e., HIV1/2 antibody positive).
8. Untreated active hepatitis B defined as HBsAg positive and HBV-DNA copy number greater than the upper limit of the normal value in the laboratory of the study center.
Note: Patients with hepatitis B who meet the following criteria can also be included:
1. HBV viral load \<1000 copies/ml (200IU/ml) before the first dose; the patient should receive anti-HBV treatment throughout chemotherapy in the entire study to avoid viral reactivation.
2. For patients who are anti-HBc (+), HBsAg (-), anti-HBs (-), and HBV viral load (-), no prophylactic anti-HBV treatment is required, but close monitoring of viral reactivation is needed.
9. Active hepatitis C virus (HCV) infection defined as HCV antibody positive and HCV-RNA levels higher than the detection limit.
10. Having received live vaccines within 30 days prior to the first dose (Cycle 1, Day 1).
Note: It is allowed to receive inactivated virus vaccines for seasonal influenza within 30 days prior to the first dose, but attenuated live influenza vaccines administered intranasally are not allowed.
11. Pregnant or lactating women;
12. Any serious or uncontrollable systemic diseases, such as:
1. Significant and symptomatic abnormalities in rhythm, conduction or morphology on resting electrocardiogram, such as complete left bundle branch block, second-degree or higher heart block, ventricular arrhythmia, or atrial fibrillation;
2. Unstable angina, congestive heart failure, or chronic heart failure classified as New York Heart Association (NYHA) class ≥ 2;
3. Any arterial thrombosis, embolism or ischemic events, such as myocardial infarction, unstable angina, cerebrovascular accident or transient ischemic attack, occurring within 6 months prior to enrollment;
4. Poor blood pressure control defined as systolic blood pressure \> 140 mmHg and/or diastolic blood pressure \> 90 mmHg;
5. A history of non-infectious pneumonia requiring glucocorticoid therapy within 1 year prior to initial treatment, or current clinical activity of interstitial lung disease;
6. Active pulmonary tuberculosis;
7. Active or uncontrolled infections requiring systemic therapy;
8. Active diverticulitis, abdominal abscess, or gastrointestinal obstruction;
9. Liver diseases such as cirrhosis, decompensated liver disease, acute or chronic active hepatitis;
10. Poorly controlled diabetes (fasting blood glucose (FBG) \> 10mmol/L);
11. Urine protein ≥ ++ on routine urinalysis, with confirmed 24-hour urine protein quantification \> 1.0 g;
12. Psychiatric disorders that are unable to comply with treatment.
13. Any other medical histories, disease evidence, treatment, or laboratory values that may interfere with the test results, hinder the full participation in the study, or other situations that the investigator deems unsuitable for inclusion due to potential risks.
