Objectives of Study:

Primary Objective:To compare the pathological complete response (pCR) rate of neoadjuvant low-dose radiotherapy (16 Gy in 8 fractions) combined with immunotherapy (tislelizumab) and chemotherapy versus neoadjuvant immunotherapy and chemotherapy alone in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Secondary Objectives:To compare event-free survival (EFS), major pathological response (MPR) rate, R0 resection rate, objective response rate (ORR), and overall survival (OS) between the two neoadjuvant treatment groups, and to evaluate the safety and tolerability profiles of the combination therapy.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用中央随机化系统进行随机分组,未设置分层因素。符合入组条件的受试者将按照 1:1比例随机分配至试验组或对照组。随机分配序列由独立人员预先生成,并由中央随机化系统管理,以保证分配隐藏。研究者在完成受试者入组资格确认后,通过中央随机化系统获得随机号及对应治疗分组。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study will use a central randomization system for treatment allocation, with no stratification factors. Eligible participants will be randomized in a 1:1 ratio to either the experimental group or the control group.The random allocation sequence will be generated in advance by personnel independent of the clinical research team and managed through the central randomization system to ensure allocation concealment. After confirming the participant’s eligibility, the investigator will obtain the randomization number and corresponding treatment allocation through the central randomization system.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

本研究采用开放标签(Open-label)设计,受试者和临床医生对分组信息不设盲。但为了保证结果的客观性,采用评价者盲法: 病理评价盲法: 负责评估主要终点(pCR)的病理科医生不获知患者的分组信息。 影像评价盲法: 负责 RECIST 1.1 疗效评价的影像科医生对分组信息设盲。 统计分析盲法: 统计分析人员在分析原始数据时,数据以 A/B 组代号呈现,直至分析完成。

Blinding:

This is an open-label study where participants and clinicians are aware of the treatment assignment due to the nature of radiotherapy and surgery. However, a blinded outcome assessment (PROBE design) is implemented: Pathological Assessment: Pathologists evaluating the primary endpoint (pCR) are blinded to the treatment assignment. Radiological Review: Radiologists performing tumor response assessments (RECIST 1.1) remain blinded to the grouping. Statistical Analysis: The study statistician will remain blinded to the treatment codes until the database is locked and the analysis plan is executed.
