简要总结
Esophageal cancer, the 7th most common cancer globally, accounts for more than half a million deaths each year. The incidence of ESCC, the most common histologic type, has been stable, whereas the incidences of esophageal and gastroesophageal junction adenocarcinomas continue to increase in Western countries.
Neoadjuvant chemoradiotherapy followed by surgery has become a standard of care for patients with locally advanced resectable esophageal or junctional cancer, especially in western countries. In Asia, nCT is considered as the standard of care for Stage II/III ESCC based on JCOG9204 and JCOG9907 trials. The superiority of nCRT/nCT, in terms of long-term survival, remains to be elucidated. For Stage II/III ESCC patients with multiple stations of lymph nodes involvement, nCT might be more appropriate for the inaccessibility of radiotherapy.
There are only limited studies on preoperative immune checkpoint inhibitor in combination with chemotherapy followed by surgery for the locally advanced ESCC. Therefore, this study intends to use Nivolumab 360 mg Q3W combined with standard chemotherapy as the neoadjuvant therapy regimen.

- Background Esophageal cancer, the 7th most common cancer globally, accounts for more than half a million deaths each year. The incidence of ESCC, the most common histologic type, has been stable, whereas the incidences of esophageal and gastroesophageal junction adenocarcinomas continue to increase in Western countries.
Neoadjuvant chemoradiotherapy followed by surgery has become a standard of care for patients with locally advanced resectable esophageal or junctional cancer, especially in western countries. In Asia (especially Japan), nCT is considered as the standard of care for Stage II/III ESCC based on JCOG9204 and JCOG9907 trials. The superiority of nCRT/nCT, in terms of long-term survival, remains to be elucidated. For Stage II/III ESCC patients with multiple stations of lymph nodes involvement, nCT might be more appropriate for the inaccessibility of radiotherapy.
There are only limited studies on preoperative immune checkpoint inhibitor in combination with chemotherapy followed by surgery for the locally advanced ESCC. Therefore, this study intends to use Nivolumab 360 mg Q3W combined with standard chemotherapy as the neoadjuvant therapy regimen. 2. Sample Size The planned sample size is approximately 81 subjects. The sample size calculations are based on the results of neoadjuvant therapy clinical research in our center (Department of Thoracic Surgery, Zhongshan Hospital Affiliated to Fudan University).
In the past two years, about 85% of patients can undergo surgery and complete the entire treatment plan, combining with the results of neoadjuvant immunotherapy in lung cancer. As calculated based on an asymptotic method, 81 patients will be 2:1 randomized to Nivolumab/Chemo and Chemo group, with 80% power to detect a 21% difference in the proportion of patients achieving a pCR at a one-sided α of 0.05, assuming a pCR rate of 25% in the Nivolumab/Chemo group and 4% in the Chemo group. Considering a 10% drop rate, 90 patients will be enrolled.
10-20 more subjects may be added to each group after the evaluation of feasibility and safety as the justification. 3. Research Process 3.1 Screening period 1) Tumor evaluation, including CT/MRI, PET/CT, endoscopy and pathological evaluation should be performed within 14 days before enrollment.

结局指标
主要结局
Pathological Complete Response (pCR) rate
时间窗: Up to the date of pathological reports obtained since the date of randomization, up to 12 months
pCR rate is defined as the proportion of the subjects in the analysis population who have a complete response in postoperative pathology. It is assessed in the resected specimen following neoadjuvant therapy using standardized work up of the resection specimen in the pathology department and standardized histological criteria for tumor regression grading. The Tumor Regression Grade (TRG) is categorized as follow: grade 1, no evidence of vital residual tumor cells (pCR); grade 2, less than 10% vital residual tumor cells; grade 3, 10 to 50%; grade 4, more than 50%.
次要结局
- R0 resection rate(Up to the date of pathological reports obtained since the date of randomization, up to 12 months)
- Events-free Survival (EFS)(Up to the date of death of any causes since the date of randomization, up to 36 months)
- Incidence of Treatment-Emergent Adverse Events(Up to the date of death of any causes since the date of randomization, up to 36 months)
- Overall survival (OS)(Up to the date of death of any causes since the date of randomization, up to 36 months)
