研究目的:

验证前期已构建的基于血浆外泌体和机器学习的模型辅助乳腺癌筛查的临床应用价值:本研究前期收集87例对照和126例乳腺癌患者血浆,检测外泌体中3个乳腺癌关键基因含量,进行初步建模,后续将再收集179例对照和253例乳腺癌患者血浆,检测外泌体中3个乳腺癌关键基因含量,纳入前期已建立的三种乳腺癌筛查模型进行预测,将预测结果与影像诊断数据进行比较、分析,再应用“金标准”病理结果综合评价模型预测结果的准确定和稳定性。最终筛选出其中一种最佳的乳腺癌患筛查模型。本研究有望为辅助乳腺癌筛查提供准确、微创、易行的新评估方法,为更好的实现乳腺癌患者的“早诊断,早治疗”提供支持。  

Objectives of Study:

Validation of the Clinical Application Value of a Plasma Exosome and Machine Learning-Based Model for Assisting Breast Cancer Screening:In the preliminary phase of this study, plasma samples from 87 control subjects and 126 breast cancer patients were collected to measure the expression levels of three key breast cancer genes within exosomes. An initial model was developed based on these data. Subsequently, plasma samples from an additional 179 control subjects and 253 breast cancer patients will be collected to measure the same three key gene levels. These data will be integrated into three previously established breast cancer screening models for prediction. The predictive results will be compared and analyzed against imaging diagnostic data. A comprehensive evaluation of the accuracy and stability of the model predictions will then be conducted using the "gold standard" pathological results.Ultimately, the study aims to identify the optimal breast cancer screening model among the three tested. This research is expected to provide a novel, accurate, minimally invasive, and practical assessment method to assist in breast cancer screening, supporting the goal of "early diagnosis and early treatment" for breast cancer patients.

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:

本研究采用病例报告表(Case Report Form,CRF)收集数据,完成的CRF由1人独立数据录入,1人审校,校对不一致时,核查原始数据确保数据信息准确。录入数据后CRF将封存以便将来审查和核对数据。数据分析将由独立的专业的生物统计学人员分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study collects data using a Case Report Form (CRF). The completed CRF will be independently entered by one person and reviewed by another. In cases of discrepancies, the original data will be verified to ensure data accuracy. After data entry, the CRFs will be sealed for future review and data verification. Data analysis will be performed by independent professional biostatisticians.
