Intervention model description: Patients fulfilling Eligibility Criteria will be included in our study. ESCC participants in this study will be given intravenous administration of SHR-1210 (200mg/3w) combined with albumin paclitaxel (260 mg/m2) plus carboplatin chemotherapy. Every three weeks for a cycle of treatment, which will be conducted twice, and minimally invasive surgery within 5-8 weeks after the last administration. Treatments will be administrated until disease progression, unacceptable adverse events (AE), concomitant diseases that hinder continued treatment.
Primary purpose: TREATMENT

Brief summary: To evaluate the efficacy and safety of camrelizumab combined with albumin paclitaxel and platinum chemotherapy in the preoperative treatment of locally advanced thoracic esophageal squamous cell carcinoma

Detailed description: Primary outcome:

1. Analysis of prognosis efficacy of patients: pathologic complete response (pCR)

Secondary outcome:

Overall survival(OS), Progressive-free survival(PFS), Disease control rate(DCR), Objective response rate(ORR), and the proportion of subjects who completed all treatments and radical resection (R0);

Explorative outcome:

To explore the efficacy of ultrasound gastroscopy, PET/CT, peripheral circulating blood tumor cell (CTC) detection and CTC-based immunofluorescence detection of PD-L1 antibody for the treatment of locally advanced ESCC with camrelizumab combined with albumin paclitaxel and platinum and potential biomarkers for predicting the efficacy of camrelizumab, including but not limited to immunohistochemical detection of PD-L1 expression in tumor specimens, T cell receptor (TCR) sequencing analysis in peripheral blood, and esophageal microbiome Analysis, etc.; patients' quality of life

* Good coagulation function before treatment, defined as International Normalized Ratio (INR) or Prothrombin Time (PT) ≤ 1.5 times ULN; if the subject is receiving anticoagulation therapy, they can also be included in this trail as long as the PT is within the intended range of anticoagulation drugs;
* For female subjects of childbearing age, they should have a negative urine or serum pregnancy test within 3 days before receiving the first study drug administration (cycle 1, day 1). If the urine pregnancy test result cannot be confirmed as negative, blood pregnancy test is required. If there is a risk of conception, male and female patients need to use high-efficiency contraception (ie, a method with a failure rate of less than 1% per year) and continue until at least 180 days after stopping the trial treatment.

For subjects with anti-HBc (+), HBsAg (-), anti-HBs (-) and HBV viral load (-), prophylactic anti-HBV treatment is not required, but virus reactivation needs to be closely monitored; active Subjects infected with HCV (HCV antibody-positive and HCV-RNA level is higher than the lower limit of detection) ;
