Metastatic Colorectal Cancer with Isolated Liver Metastasis
Patients with advanced colorectal cancer with isolated liver metastasis. Primary cancer must be resectable (if no archival exists) and patient must be planned for liver resection with at least 3 cycles of chemotherapy prior to liver surgery.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Sampling Method: | Probability Sample |
Eligibility Criteria:
- Patients must have histologically confirmed CRC with isolated liver metastasis
- Patients must be planned for a hepatic metastasectomy
- Patients must have received at least 3 cycles of chemotherapy (FOLFOX or FOLFIRI with or without Bevacizumab) prior to the planned hepatic metastasectomy
- Primary tumor must be considered resectable with a plan for this to either occur concurrently with the liver resection or subsequent to this.
- If primary has already been resected before liver resection, archival tissue must be available for genomic analysis
- Patients must be 18yrs of age or older
- Ability to understand and willing to sign a written informed consent document
Exclusion Criteria:
- Patients with un-resectable or borderline resectable isolated liver metastases as judged by the multidisciplinary hepatobiliary tumor board at PM or BCCA after a course of pre-operative chemotherapy will be excluded
- Patients with evidence of possible metastatic disease at any sites outside the liver are not eligible
- Patients with any major co-morbidity or co-morbidities that will render liver resection very high risk in investigator's opinion
- Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures.
- Patients with a previous history of another primary cancer treated within 5 years of study entry are not eligible except those with basal cell or squamous cell carcinoma of the skin and intraepithelial neoplasia.
