随机方法(请说明由何人用什么方法产生随机序列):

对符合入选标准并签署知情同意书的患者进行中央化随机。随机采用按?N分期(N0?vs?N1)分层的区组随机法,区组长度为6。独立统计师使用 SAS?9.4预先生成随机序列,按1:1比例将受试者分配至新辅助化疗组(实验组)和直接手术组(对照组)。生成的随机号以Excel工作簿形式保存,含随机序号、区组号及对应治疗组别。Excel 文件由指定的随机化管理员保管:当中心确认受试者符合条件并完成知情同意后,管理员从相应工作表按顺序提取下一行随机号,通过微信或电子邮件反馈给研究中心,避免跳号或重复。提取后的行在Excel中即时做“使用”标记并锁定,形成纸质及电子双重痕迹,所有操作留下签名和时间戳。本研究为开放标签设计(未设盲),因化疗和手术方案的操作差异,无法对研究者和受试者设盲,但围术期结果、病理评估、远期预后等均由对治疗分组不知情的独立评估者按盲法进行,从而降低观察者偏倚。

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

Centralized randomization will be performed for patients who meet the inclusion criteria and have signed the informed consent form. Randomization will use a block randomization method stratified by N stage (N0 vs N1), with a block size of 6. An independent statistician will generate the random sequence in advance using SAS 9.4, and subjects will be assigned to either the neoadjuvant chemotherapy group (experimental group) or the direct surgery group (control group) at a 1:1 ratio. The generated random numbers will be saved in an Excel workbook containing the random sequence number, block number, and corresponding treatment group. The Excel file will be kept by the designated randomization administrator: once the center confirms that a subject meets the criteria and completes informed consent, the administrator will extract the next row of random numbers from the corresponding worksheet in sequence and provide it to the study center via WeChat or email, avoiding skipped or duplicated numbers. The extracted row will be immediately marked as "used" and locked in Excel, creating both paper and electronic traces, with all operations leaving a signature and timestamp. This study is an open-label design (no blinding). Due to operational differences in chemotherapy and surgical procedures, blinding of investigators and subjects is not possible, but perioperative outcomes, pathological assessment, and long-term prognosis will be evaluated by independent assessors who are blinded to treatment groups, thereby reducing observer bias.
