研究目的:

本研究旨在开发并验证一个整合表达谱基因组学与临床特征的预测模型,以精准评估中低位局部晚期直肠癌(LARC)患者对新辅助放化疗的敏感性及预后,从而在治疗前识别潜在抵抗的高危患者,为其个体化的强化治疗策略提供依据;同时,通过建设具备完整临床随访信息的LARC生物样本库与数据库,为未来的多组学深入研究奠定资源基础,并计划在权威学术期刊发表成果,以推动该领域的精准医疗发展。  

Objectives of Study:

This study aims to develop and validate a predictive model integrating expression-based genomics and clinical features to accurately assess the sensitivity to neoadjuvant chemoradiotherapy and prognosis in patients with mid-low locally advanced rectal cancer (LARC). The goal is to identify high-risk patients potentially resistant to treatment before its initiation, thereby informing individualized, intensified therapeutic strategies. Concurrently, the project will establish a biorepository and database of LARC samples with comprehensive clinical follow-up, creating a foundational resource for future in-depth multi-omics research. The findings are planned for publication in authoritative academic journals to advance the field of precision medicine.
