Neoadjuvant Anti-PD-1 Plus Chemotherapy in Locally Advanced Resectable Esophageal Squamous Cell Carcinoma

Prior treatment

• Pre-treatment stage as cN2-3 or cT4b(non-curatively-resectable verified by the local surgical investigator, AJCC/UICC 7th Edition);
• Patients with another previous or current malignant disease which is likely to interfere with treatment or the assessment of response in the judgement of the local surgical investigator.
• Participation in another intervention clinical trial with interference to the therapeutic intervention during this study or during the last 30 days prior to informed consent;

Other illness

• Patients with advanced inoperable or metastatic esophageal cancer;
• Any patient with a significant medical condition which is thought unlikely to tolerate the therapies. Such as cardiac disease (e.g. symptomatic coronary artery disease or myocardial infarction within last 12 months), clinically-significant lung disease, clinically-significant bone marrow, liver, renal function disorder;
• Allergy to any drugs;

Other

• Patients with non-squamous cell carcinoma histology;
• Pre-treatment stage as cT1-2N0-1M0 (AJCC/UICC 7th Edition);
• Pregnant or lactating women and fertile women who will not be using contraception during the trial;
• Expected lack of compliance with the protocol.

• Histologically-confirmed squamous cell carcinoma of the esophagus;
• Tumors of the esophagus are located in the thoracic cavity;
• Pre-treatment stage as cT3-4aN0-1M0 (AJCC/UICC 7th Edition) (In case of stage cT4a, curative resectability has to be explicitly verified by the local surgical investigator prior to randomization).
• Age is between 18 years and 75 years,
• Eastern Cooperative Oncology Group (ECOG) performance status 0-1;
• Adequate cardiac function. All patients should perform ECG, and those with a cardiac history or ECG abnormality should perform echocardiography with the left ventricular ejection fraction \> 50 %;
• Adequate respiratory function with FEV1≥1.2L, FEV1%≥50% and DLCO≥50% shown in pulmonary function tests;
• Adequate bone marrow function (White Blood Cells \>4x10\^9 /L; Neutrophil \>2.0×10\^9 /L; Hemoglobin \> 90 g/L; platelets\>100x10\^9 /L);
• Adequate liver function (Total bilirubin \<1.5x Upper Level of Normal (ULN); Aspartate transaminase(AST) and Alanine transaminase (ALT)\<1.5x ULN);
• Adequate renal function (Glomerular filtration rate (CCr) \>60 ml/min; serum creatinine (SCr) ≤120 µmol/L);
• The patient has provided written informed consent and is able to understand and comply with the study;
