Objectives of Study: |
Primary Objective: To evaluate the superiority of Laparoscopic Proximal Gastrectomy with Tubular-based Right-Opening Single-Flap Plasty (LPG-tbROSF) compared to Standard Laparoscopic Total Gastrectomy (LTG) in improving postoperative nutritional outcomes for patients with localized proximal gastric cancer. Secondary Objectives: 1.To investigate the effectiveness of LPG-tbROSF in improving postoperative quality of life. 2.To explore the efficacy of LPG-tbROSF in controlling postoperative gastroesophageal reflux. 3.To assess and compare the perioperative safety profiles of the two surgical approaches. 4.To compare the long-term oncological outcomes between LPG-tbROSF and LTG. |

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的分配方式。由独立于研究团队的统计学家使用计算机随机数生成程序(如IBM SPSS Statistics 26.0软件)预先生成随机分配序列。随机序列采用区组随机化方法(区组大小=4),并按参与中心进行分层,以确保各中心两组例数均衡、控制潜在的中心效应。随机种子数由统计人员设置以保证不可预测性。所有随机序列密封于不透明编号信封中保存,各中心设专人(研究协调员)根据患者入组顺序开启信封,进行随机分组隐藏和通知。同时,研究将使用统一的电子数据采集系统(Electronic Data Capture, EDC)录入随机结果并建立患者身份与分组的对应,以确保分配过程的准确记录。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study will employ a central randomization method for treatment allocation. The random allocation sequence will be generated in advance by a statistician, who is independent of the study team, using a validated computer-based random number generator (e.g., IBM SPSS Statistics 26.0). The sequence will be generated using a blocked randomization method (with a block size of 4) and will be stratified by participating center. This approach aims to ensure balanced sample sizes between the treatment groups within each center and to control for potential confounding center effects. A random seed will be set by the statistician to ensure the unpredictability of the sequence. Allocation concealment will be ensured using sequentially numbered, opaque, sealed envelopes (SNOSE). At each center, a designated research coordinator will be responsible for opening the next available envelope in sequence upon a patient's confirmed enrollment to reveal the group assignment. Concurrently, the allocation result will be entered into a centralized Electronic Data Capture (EDC) system, which will link the patient identifier to their assigned group. This process ensures an accurate and auditable record of the patient allocation. |

盲法: |
所有术后随访评估(如生活质量问卷、内镜结果判读)均由不知晓患者分组的独立评估员执行 。此外,数据统计分析也由独立的盲态统计师完成 ,数据和安全监察委员会(DSMB)在审阅数据时同样保持盲态 。任何意外的盲态破坏都将被记录并报告 。 |
|
Blinding: |
To mitigate bias, all post-operative follow-up assessments (e.g., quality of life questionnaires, interpretation of endoscopic findings) will be conducted by independent assessors who are blinded to patient group assignments. Additionally, a separate, blinded statistician will perform the data analysis. The Data and Safety Monitoring Board (DSMB) will also remain blinded during its data reviews. Any unintentional unblinding will be documented and reported. |
