Eligibility Criteria

Age 18+ · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Able to understand the information provided Informed consent/assent is a process through which a person voluntarily agrees to participate in a study after being given a full explanation of the study
The person has a cancer that has spread to the liver and no other parts of the body.
This text is saying that microsatellite instability testing must be either MSI-stable or MSI-low.
Participants must have at least one intrahepatic lesion in order to be eligible for SBRT
The participant must be a surgical candidate who is looking to have all of their known diseases eradicated with one additional surgery
If a person had surgery to remove extra-hepatic metastatic disease more than a year ago and now new extra-hepatic disease has been found, they are allowed to participate in the study.
You must be at least 18 years old in order to sign this form.
The tumor must be proficient in mismatch repair, as determined by microsatellite instability or immunohistochemistry for MMR proteins.
To ensure accurate results, IHC for MMR proteins must demonstrate the presence of intact MMR proteins.
Histologic confirmation of a colorectal primary tumor is acceptable if accompanied by radiographic evidence of metastatic disease.
