Exclusion criteria
Exclusion criteria: 1.Patients who have previously received surgery, radiotherapy, chemotherapy, targeted therapy, or immunotherapy for esophageal squamous cell carcinoma; 2.Patients with distant organ metastasis; 3.Patients with esophageal squamous cell carcinoma who have had active bleeding from the primary lesion within 2 months; patients with tumors that may invade the bronchus or major blood vessels and have a bleeding tendency. 4.Patients who have received systemic corticosteroids (more than 10 mg prednisone or equivalent per day) or other immunosuppressive agents (including but not limited to cyclophosphamide, methotrexate, thalidomide, etc.) within 14 days before the first drug administration, or are expected to require such treatment during the study period. However, physiological doses of corticosteroids (i.e., 150 mmHg and/or diastolic blood pressure >100 mmHg) and considered clinically significant by the investigator; b) History of hypertensive crisis or hypertensive encephalopathy; c) History of intracranial or spinal hemorrhage; d) Current evidence of bleeding tendency or severe coagulopathy (without anticoagulant therapy) or tumor involvement of major blood vessels; e) Hemoptysis within 1 month before the first dose (each episode with >= 1/2 teaspoon of bright red blood) or a history of gastrointestinal bleeding that is deemed ineligible by the investigator; f) Current evidence of free abdominal air; g) Current presence of severe, non-healing, or open wounds, or untreated fractures; h) Any other disease that, in the investigator's judgment, may lead to an unacceptable risk of adverse events during the study treatment. 7.Subjects with any of the following cardiovascular diseases are excluded. a) Myocardial infarction, unstable angina, pulmonary embolism, acute/sustained myocardial ischemia, cerebrovascular accident, transient ischemic attack, or other clinically significant/medication-requiring arteriovenous thromboembolic or ischemic events within 6 months before the first drug administration; b) Past and/or current NYHA class III~IV congestive heart failure; c) Past and/or current severe arrhythmia requiring drug treatment; d) Mean QT interval (QTcF) >470 ms on 12-lead ECG before the first drug administration. 8.Concomitant tumors in other organs; 9.Acute or chronic hepatitis B or C virus infection; 10.HIV-positive patients; those who have received antituberculosis treatment within one year before the first study treatment; HBsAg-positive individuals with HBV DNA >= 2000 IU/ml or 104 copies/ml; HCV antibody-positive individuals with positive HCV RNA. 11.Known active tuberculosis; known active
