研究目的:

1. 构建基于国产放疗设备的短期疗效预测模型:以国产创新放疗平台(如联影CT加速器、大医TAICHI系统)采集的放疗前后CT影像为基础,提取设备适配的影像组学特征,构建专属国产设备的疗效评估模型,预测短期复发/进展风险,为宫颈癌患者提供早期风险分层依据; 2. 开展国产设备影像特征的生物机制验证:采集治疗前后肿瘤组织样本,通过转录组测序(bulk/scRNA-seq)及免疫组化,解析国产设备影像特征驱动的高风险评分所对应的分子机制(如免疫微环境抑制、DNA损伤修复增强等),验证国产设备成像的生物学表征能力; 3. 实现国产技术生态的闭环优化:将机制分析发现的分子特征反馈至模型构建,优化国产设备影像特征选择与模型结构,提升预测性能与可解释性,支撑国产智能放疗平台(如在线自适应系统)的临床决策精准化。  

Objectives of Study:

1. Construct a short-term efficacy prediction model based on domestically produced radiotherapy equipment: Using pre- and post-radiotherapy CT images collected from domestic innovative radiotherapy platforms (such as United Imaging CT accelerators and DHC TAICHI systems), extract radiomics features compatible with the equipment, and build efficacy assessment models specific to domestic devices to predict short-term recurrence/progression risk, providing early risk stratification for cervical cancer patients; 2. Conduct biological mechanism validation of imaging features from domestic equipment: Collect tumor tissue samples before and after treatment, and through transcriptome sequencing (bulk/scRNA-seq) and immunohistochemistry, analyze the molecular mechanisms corresponding to high-risk scores driven by imaging features from domestic equipment (e.g., immune microenvironment suppression, enhanced DNA damage repair), validating the biological representational capability of imaging from domestic devices; 3. Achieve closed-loop optimization of the domestic technology ecosystem: Feed the molecular features discovered from mechanism analysis back into model construction, optimize the selection of imaging features and model structures for domestic equipment, enhance predictive performance and interpretability, and support precise clinical decision-making for domestic intelligent radiotherapy platforms (such as online adaptive systems).
