研究目的: |
本研究旨在探究乳腺癌肺转移过程中,远端肺生态位微生物群落的组成特征及其与生态位结构(如免疫微环境、细胞外基质)的关联性;筛选与肺转移进展相关的特征性微生物标志物,分析其与患者临床病理特征及预后的关系,明确微生物群落调控远端肺生态位促进乳腺癌转移的潜在机制,为揭示微生物在乳腺癌肺转移中的作用及开发预后评估指标提供初步临床依据。 |

Objectives of Study: |
This study aims to investigate the compositional characteristics of microbial communities within the distal lung niche during breast cancer metastasis and to elucidate their associations with niche structures such as the immune microenvironment and extracellular matrix. It further seeks to identify characteristic microbial biomarkers related to lung metastasis progression, analyze their correlations with clinicopathological features and patient prognosis, and clarify the potential mechanisms by which microbial communities regulate the distal lung niche to promote breast cancer metastasis. The findings are expected to provide preliminary clinical evidence for unveiling the role of microbiota in breast cancer lung metastasis and for developing prognostic evaluation indicators. |

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): |
去标识化的原始数据(包括测序数据和临床相关信息)将在主要研究结果发表后 6 个月内通过安全的网络数据库共享(如中国国家基因库 CNGBdb 或 NCBI GEO/SRA),并提供元数据及研究方案。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
De-identified raw data (including sequencing data and clinical metadata) will be shared via a secure web-based public database (e.g., China National GeneBank DataBase, CNGBdb, or NCBI GEO/SRA) within 6 months after publication of the main results. Metadata and protocol will be provided. |
|
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: |
本研究数据由研究医生通过统一设计的纸质病例报告表(CRF)进行手工记录,研究助理负责整理与核查。所有资料均存放于专用档案柜内,定期由独立人员复核,确保数据的真实性、完整性和一致性。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data will be manually recorded using standardized paper Case Report Forms (CRFs). Research assistants will organize and verify the data. All records will be stored in locked archives and regularly reviewed by independent monitors to ensure accuracy, completeness, and consistency. |
