研究目的: |
以接受内分泌治疗的绝经前乳腺癌患者为研究对象,比较 OFS+AI 与 OFS+TAM 两种方案下,阴道微生物群纵向变化特征及其与 GSM 临床表现的关系,探索乳腺癌内分泌治疗相关 GSM 的阴道微生态机制。 1 描述 OFS+AI 组与 OFS+TAM 组患者在 12 个月随访期间阴道菌群多样性及乳酸杆菌相对丰度的变化轨迹; 2 比较两组患者阴道微生物群特征差异,并评估内分泌方案对阴道微生态变化的独立影响; 3 分析阴道菌群多样性、乳酸杆菌丰度与 VHI、GSM 症状 VAS、ICIQ-SF 评分之间的相关性; 为后续基于阴道微生态的 GSM 防治策略(包括 VMT 或其他微生态干预)提供前期临床证据和靶点依据。 |

Objectives of Study: |
Taking premenopausal breast cancer patients receiving endocrine therapy as the study population, this study aims to compare the longitudinal changes in vaginal microbiota and their association with clinical manifestations of GSM under two regimens, OFS+AI and OFS+TAM, and to explore the vaginal microecological mechanisms underlying endocrine therapy–related GSM in breast cancer. 1 To describe the trajectories of vaginal microbiota diversity and the relative abundance of Lactobacillus in patients in the OFS+AI group and the OFS+TAM group over a 12?month follow?up period; 2 To compare differences in vaginal microbiome characteristics between the two groups and to evaluate the independent effect of endocrine regimens on changes in the vaginal microecology; 3 To analyze the correlations between vaginal microbiota diversity, Lactobacillus abundance, and VHI, GSM symptom VAS, and ICIQ-SF scores; These findings will provide preliminary clinical evidence and potential targets for subsequent GSM prevention and treatment strategies based on the vaginal microecology (including VMT or other microbiota-based interventions). |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
本研究将在主要研究结果论文正式发表后6个月内,通过ResMan临床试验公共管理平台(https://www.resman.org)共享经去标识化处理的个体参与者原始数据。其他研究者可提交数据使用申请,经项目负责人及伦理委员会批准后获取。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
The study data will be made publicly available through the ResMan Clinical Trial Public Management Platform (https://www.resman.org) within six months after the main study results are formally published. Researchers may submit an online request for data access. Access will be granted upon approval by the principal investigator and the original ethics committee. The shared data will be available for non-commercial academic research purposes only. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用标准化病例记录表(CRF),涵盖人口学信息、暴露史、临床检查结果及随访结局等变量。目前数据通过加密电子表格(如 Excel)进行初步管理,并计划在正式数据清理阶段迁移至 ResMan 电子数据采集系统(https://www.resman.org)进行统一质控与归档。所有原始记录由浙江大学医学院附属妇产科医院外科课题组在符合伦理要求的前提下安全保存至少5年。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data are initially recorded on standardized paper CRFs and then entered into encrypted spreadsheets (e.g., Microsoft Excel) for management. The research team plans to migrate the dataset to ResMan (https://www.resman.org), a web-based EDC system, for quality control and long-term archiving prior to data sharing. |
