Esophageal Squamous Cell Carcinoma
Conditions
Brief summary
This study used an open single center study design to observe the efficacy and safety of Penpulimab combined with Chemoradiotherapy(CRT) in preoperative T2,3,4aN0-1-2M0 esophageal squamous cell carcinoma (ESCC).
Interventions
DRUGPenpulimab Combined With CRT
1. Penpulimab: 200mg, intravenous infusion, once every two weeks. After completing two courses of CRT, continue to send Penpulimab 200mg every two weeks on the first and 14th days after the completion of CRT, two courses of treatment, a total of four courses. 2. Radiotherapy 40gy/20fx, once a day from Monday to Friday, completed in 4 weeks; 3. PC regimen: Paclitaxel 50mg/m2, intravenous drip, carboplatin AUC=2mg/ml/min, intravenous drip, once a week during radiotherapy, a total of 4 courses, the specific time is D1, 8, 15, 22 days after the beginning of radiotherapy. 4. Gastrointestinal reactions such as nausea and vomiting should be routinely prevented before chemotherapy. Dexamethasone 10mg should be used 30 \ 60 minutes before paclitaxel, and intramuscular injection should be stopped immediately in case of drug or infusion reactions.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| pathological complete remission（pCR）rate | 3 to 4 months | Proportion of subjects who achieved pathological complete remission (PCR)，PCR was defined as the microscopic absence of tumor cells in the pathological evaluation of excised esophageal cancer lesions and regional lymph node samples after surgery. |
| safety（AE or SAE） | 2 to 3 years from baseline | Incidence of adverse events or serious adverse events |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Event free survival（EFS） | 2 to 3 years from baseline | Date of first administration to date of first recording of relevant events |
| Tumor regression grade（TRG） | 3 to 4 months | Evaluation of the focus of primary tumor after radiotherapy and chemotherapy |
| Disease free survival（DFS） | 2 to 3 years from baseline | Date from the operation to the first recording of relevant events |
| Overall survival（OS） | 2 to 3 years from baseline | Date of first administration to date of death due to any cause |
| R0 resection rate | 3 to 4 months | Proportion of subjects reaching R0 resection. resection was defined as no tumor cells remained within 1mm of the two cutting edges of the esophageal cancer lesions removed during the operation. |
