Brief Summary:
Resection of liver metastasis is potentially curative in patients with colorectal cancer bearing liver metastasis. However, early recurrence occurs in up to 30% in 3 months after liver resection. To optimize patient selection, the investigators propose to evaluate the the value of incorporating circulating tumor cells enumeration to clinical factors in a prospective study

Condition or disease Intervention/treatment
Metastatic Colorectal Cancer Circulating Tumor Cell Diagnostic Test: Circulating tumor cell

Detailed Description:
This is a single-center prospective study to evaluate the predictive value of circulating tumor cells (CTC) in patients with metastatic colorectal cancer who are planned to have curative resection of liver metastasis. Blood will be taken from patients within 7 days before liver resection. CTC enumeration is done by a highly-sensitive microfluidic platform for which CTC can be subsequently enumerated with or without sequencing performed. Patients are then followed up regularly with contrast CT scan for recurrence. The primary study endpoint is to define the cutoff value of CTC count in patients with early relapse < 6months after liver resection. Seventy-seven patients will be recruited in 24 months.

Intervention Details:
  • Diagnostic Test: Circulating tumor cell
    Circulating tumor cell enumeration and sequencing

Primary Outcome Measures :
  1. Cutoff value of CTC counts [ Time Frame: Progression free survival at 6 months ]
    to identify patients with early relapse (<6 months) after liver resection as determined by the AUC under the ROC curve

Secondary Outcome Measures :
  1. A immuno-clinical scoring system [ Time Frame: Progression free survival at 6 months ]
    A system combining CTC count with clinical factors to stratify patients before liver resection

  2. Progression free survival [ Time Frame: up to 5 years ]
    Time from liver resection to date of relapse or date of death, whichever is earlier

  3. Overall survival [ Time Frame: up to 5 years ]
    Time from liver resection to date of death

Biospecimen Retention:   Samples With DNA
blood in Streck tube will be processed for isolating circulating tumor cells and its DNA content for subsequent sequencing if feasible
