Stereotactic Body Radiation Therapy (SBRT) for Unresectable Liver Metastases

Study Purpose

This is a Phase II study to determine the efficacy of SBRT to treat liver metastases in patients with Colorectal Adenocarcinoma, Carcinoma of the Anal Canal and Gastrointestinal Neuroendocrine Tumors that are not amenable to surgery. Patients should have no evidence of extra-hepatic disease or have disease that is planned to be treated with curative intent. Therefore, SBRT is being considered as a potentially curative procedure.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT02185443
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
