研究目的: |
主要目的: 评估在BCG灌注治疗期间,采用低谷氨酸饮食是否能显著降低非基底层型NMIBC患者的1年复发率(基于膀胱镜+活检确认)。 次要目的: 1.比较两组患者的24个月无复发生存期(RFS)、无进展生存期(PFS,进展至肌层浸润或转移)和疾病特异性生存率(DSS)。 2.评估低谷氨酸饮食联合BCG治疗的安全性谱。 探索性目的: 1.动态监测尿液谷氨酸水平及血清氨基酸谱,分析其与饮食依从性及复发风险的相关性。 2.对符合条件的二次活检肿瘤组织,利用多重免疫荧光(mIHC)分析肿瘤微环境内CD8+ T细胞、Treg、巨噬细胞等免疫细胞浸润密度和空间分布的变化。 |

|
Objectives of Study: |
Primary Objective: To evaluate whether adopting a glutamate-lowering diet during BCG instillation therapy significantly reduces the 1-year recurrence rate (confirmed by cystoscopy plus biopsy) in non-basal subtype NMIBC patients. Secondary Objectives: 1.To compare the 24-month recurrence-free survival (RFS), progression-free survival (PFS; progression to muscle invasion or metastasis), and disease-specific survival (DSS) between the two patient groups; 2.To assess the safety profile of combining a glutamate-lowering diet with BCG therapy. Exploratory Objectives: 1.To longitudinally monitor urinary glutamate levels and serum amino acid profiles, analyzing their correlations with dietary adherence and recurrence risk. 2.For eligible tumor tissues from repeat biopsies, to analyze changes in immune cell infiltration density (e.g., CD8+ T cells, Tregs, macrophages) and spatial distribution within the tumor microenvironment using multiplex immunohistochemistry (mIHC). |

随机方法(请说明由何人用什么方法产生随机序列): |
采用计算机生成的区组随机化序列,通过独立的中央随机系统(如IWRS)实施。根据肿瘤分期(Ta vs. T1) 和是否伴有CIS 进行分层随机,以确保两组间基线风险均衡。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A computer-generated block randomization sequence was implemented via an independent centralized randomization system (e.g., IWRS). Stratified randomization was performed according to tumor stage (Ta vs. T1) and presence of carcinoma in situ (CIS) to ensure balanced baseline risks between treatment groups |
