Brief Title: Circulating Tumor DNA Guided Therapeutic Strategies for CRC Patients With Small Pulmonary Nodules
Official Title: Circulating Tumor DNA Guided Therapeutic Strategies for Colorectal Cancer Patients With Small Pulmonary Nodules Suspected to be Metastases: an Open-Label, Prospective, Phase II Cohort Study
Study ID: NCT05495672
Brief Summary: The clinical diagnosis and treatment of small pulmonary nodules (suspected to be lung metastases) in advanced colorectal cancer patients remain controversy. Previous studies have shown that tumor-informed circulating tumor DNA (ctDNA) blood testing can sensitively detect residual cancer. Postoperative ctDNA in colorectal cancer patients is a valuable biomarker to identify minimal residual disease (MRD) after radical resection, which is possibly useful in redefining the risk group of patients and guiding postoperative treatment. This study aimed to explore the clinical value of therapeutic strategies based on tumor-informed ctDNA test in advanved colorectal cancer patients with small pulmonary nodules.
