研究目的: |
旨在从肠道微生物中分离培养与结直肠癌发生发展相关的关键微生物(细菌),同时检测其在不同部位(癌症、癌旁与正常组织)的含量;并进一步探究关键细菌结直肠癌发生发展过程中可能存在的机制研究;由此初步证明关键细菌可能作为结直肠癌临床诊断的判定依据。 |

|
Objectives of Study: |
This study aims to: isolate and identify key bacteria from the gut microbiota that are associated with colorectal cancer (CRC) pathogenesis; quantify their abundance in different tissue sites (cancer, paracancerous, and normal tissues); and 3) investigate their underlying mechanisms in CRC development. Our goal is to provide preliminary evidence supporting the potential of these key bacteria as diagnostic biomarkers for CRC. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection was conducted using a custom-designed electronic Case Report Form (eCRF). All data were entered, stored, and managed via a web-based electronic data capture (EDC) system. This system featured access controls, logical checks, and automated query management to ensure data accuracy, integrity, and traceability. |
