Official title
A Multicenter, Observational Clinical Study Evaluating the Application of Multi-Omics Tumor-agnostic Technology for Localizing Postoperative Local Recurrence and Distant Metastasis in Colorectal Cancer
Overview
With high incidence and mortality rate, the effective therapeutic options of colorectal cancer remain limited. Up to 50% of patients with colorectal cancer will develop metastatic disease. Recurrent lesions can be diagnosed and characterized only when tumors have reached a certain volume by present radiologic imaging techniques such as CT and MRI. The exploration of differentiated clinical applications specifically for local recurrence versus distant metastasis remains an unmet need. The aim of this study is to explore methylation, fragmentomic, and cfRNA markers associated with local recurrence and distant metastasis of colorectal cancer by multi-omics approaches. By constructing a predictive model for the localization of post-treatment recurrence and metastasis, this study will compare the accuracy of different technical approaches in predicting the localization of recurrence and metastasis after colorectal cancer treatment.
Primary outcome measures
- Area Under the Receiver Operating Characteristic Curve (AUC) of the prediction models based on methylation, fragmentomics, and cfRNA data for local recurrence and distant metastasis localization in colorectal cancer [Time frame: At baseline (at the time of study enrollment, prior to any surgical or anti-tumor treatment)]
Secondary outcome measures (2)
- Accuracy of the prediction models based on methylation, fragmentomics, and cfRNA data for colorectal cancer recurrence and metastasis localization [Time frame: Baseline (at enrollment)]
- Sensitivity and specificity of individual omics technologies (methylation, fragmentomics, and cfRNA) [Time frame: Baseline (at enrollment)]
