Performance of Multi-Cancer Detection Test in Asymptomatic Patients With Neoplastic Lesions
Performance Validation of a Blood-Based Multi-Cancer Early Detection Model in Asymptomatic Patients With Cancer and Precancerous Lesions: A Multicenter Case-Only Study
This multicenter, observational case-only study will evaluate the clinical performance of a blood-based, cell-free DNA (cfDNA) methylation multi-cancer early detection (MCED) test in adults aged 50 to 74 years with confirmed invasive cancer or selected high-risk precancerous lesions/carcinoma in situ.
The study will primarily recruit patients who had no cancer-related symptoms before diagnosis. An additional tissue-of-origin (TOO) model optimization cohort will include patients with urothelial cancer, colorectal advanced adenoma, gastric high-grade dysplasia, or esophageal high-grade dysplasia, irrespective of symptom status.
調査の概要
詳細な説明
Previous case-control studies have shown promising performance in patients with established cancer diagnoses. However, conventional case-control studies predominantly enroll symptomatic patients, whose tumor burden and circulating tumor DNA (ctDNA) levels may differ from those of asymptomatic patients, even at the same cancer stage. Consequently, the sensitivity and tissue-of-origin (TOO) accuracy observed in conventional case-control studies may not fully reflect test performance in the intended screening setting. Further evaluation in asymptomatic patients with cancer is therefore needed to better characterize the technical performance of MCED tests.
This multicenter, observational, case-only study aims to evaluate the performance of a cfDNA methylation-based MCED model in patients with asymptomatic cancers and selected high-risk precancerous lesions or carcinoma in situ. The study will also support targeted optimization of the TOO prediction model for selected disease categories.
Approximately 948 participants are planned for consent and pre-treatment blood sampling. MCED test results will not be disclosed to participants or treating investigators or used to guide clinical management. The study is expected to provide additional evidence on the technical performance of cfDNA methylation-based MCED testing in asymptomatic patients and to support further model development and clinical evaluation.
