Официальное название
Circulating Tumor DNA in Patients With Colorectal Cancer Undergoing Curative-intent Surgery for Liver Metastases: Prospective, Multicenter, GERCOR Cohort
Обзор
This is a prospective multicenter cohort study, was designed to explore the prognostic value of ctDNA as a biomarker of disease response and recurrence or death in patients undergoing curative-intent surgical resection of Colorectal cancer liver metastasis.
Подробное описание
Blood collection times according to specific clinical situations:
* Standard approach * Combined surgery * Reverse strategy * Two-stage hepatectomy

- Has history of another primary cancer within the last 5 years, with the exception of non-melanomatous skin cancer and carcinoma in situ of the cervix,
- Has no more than two surgical procedures planned for complete resection of primary tumor and/or liver metastases,
- Has deficient mismatch repair (dMMR)/ microsatellite instability (MSI) tumors treated with immunotherapy,
- Blood samples cannot be collected if surgical procedure,
- Is pregnant or breastfeeding,
- Cannot be followed-up due to geographical, social, or psychic conditions,
