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

  • Number of event-free survival (EFS) in patients who undergo curative-intent resection of CRLM. [Срок оценки: Up to 4 years]
  • Overall survival (OS) n patients who undergo curative-intent resection of CRLM. [Срок оценки: Up to 4 years]
  • Time to surgical failure (TSF) in patients who undergo curative-intent resection of CRLM. [Срок оценки: Up to 4 years]
  • Prognostic value of ctDNA [Срок оценки: Up to 4 years]
  • Prognostic factor(s) for disease recurrence and survival. [Срок оценки: Up to 4 years]
  • Association between ctDNA and clinical features. [Срок оценки: Up to 4 years]

  • Has resected primary tumor or is eligible to primary tumor and CRLM (in case of synchronous metastases) resection within 6 months prior to study inclusion,
  • Has isolated CRLM that is deemed resectable or potentially resectable (extrahepatic metastases excluded, except infracentimetric non-specific lung lesions with largest diameter <1 cm and maximal number of ≤3) as judged by a multidisciplinary team meeting (based on CT scans of chest, abdomen, and pelvis \[or MRI if CT not possible\]),

  • Has definitively unresectable CLRM,
  • Had more than 9 pre-operative cycles of chemotherapy for treatment of metastatic disease planned at inclusion,
  • Has not resected primary rectal tumor (low and middle),
  • 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,
  • Has medical or psychiatric condition or occupational responsibilities that may preclude compliance with the protocol,
