Exclude patients with cervical segment esophageal cancer;
Previous history of allergy to monoclonal antibodies, any component of karelizumab, albumin-bound paclitaxel, carboplatin or other platinum drugs;
patients with moderate or greater chest and back pain and risk of esophageal perforation.
have received or are receiving any of the following treatments in the past: (1) any radiotherapy, chemotherapy, or other antineoplastic agents directed against the tumor; (2) Treatment with immunosuppressive drugs, or systemic hormonal drugs for immunosuppression (doses >10 mg/day prednisone or equivalent) within 2 weeks prior to first use of study drug; inhaled or topical steroids and adrenocorticotropic hormone replacement at doses >10 mg/day prednisone or equivalent are permissible in the absence of active autoimmune disease; (3) Received a live attenuated vaccine within 4 weeks prior to first use of study drug; (4) Major surgery or severe trauma within 4 weeks prior to first use of study drug;
Have any active autoimmune disease or history of autoimmune disease, including but not limited to: interstitial pneumonitis, enteritis, hepatitis, pituitary gland inflammation, vasculitis, nephritis, hyperthyroidism, hypothyroidism (may be considered for inclusion after hormone replacement therapy); patients with psoriasis or childhood asthma/allergies that have been in complete remission and do not require any interventions in adulthood may be considered for inclusion, but patients requiring bronchial Patients who require medical intervention with bronchodilators may not be included;

In the judgment of the investigator, there are other factors that may lead to forced termination of the study in the middle of the study, such as suffering from other serious illnesses (including psychiatric illnesses) that require comorbid treatment, alcoholism, drug abuse, family or social factors that may affect the safety of or compliance with the subject.
