Brief summary

RATIONALE: Stereotactic radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue. PURPOSE: This phase I/II trial is studying the side effects and best dose of stereotactic radiation therapy in treating patients with liver metastases.

Detailed description

OUTLINE: This is a phase I/II, dose-escalation study. Phase I: Patients undergo either percutaneous placement of metallic fiducial markers within the liver or respiratory-correlated cone-beam computed tomography for stereotactic targeting and planning. Patients then undergo single-fraction stereotactic body radiotherapy over approximately 1 hour within 1 week of the marker placement. Phase II: Patients undergo treatment as in phase I at the maximum tolerated dose. After completion of study treatment, patients will be followed at weeks 4 and 12 and then every 3 months for 2 years. PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.

Inclusion criteria

* Histological confirmation (any histology except lymphoma, leukemia, or hepatocellular carcinoma) of at least one liver lesion that is synchronous to the primary diagnosis of malignancy or metachronous as a recurrence/metastasis or as a failure following previous therapy (except radiotherapy). * One to three metastatic liver lesions =\< 5 cm in dimension. * Intrahepatic cholangiocarcinoma is acceptable for inclusion. * Zubrod Performance Status (PS) 0 or 1. * Please contact study investigator and/or consult protocol document for specific details on laboratory criteria. * Life expectancy \>= 12 weeks. * MELD (Model for End-Stage Liver Disease) score =\< 16. * \>= 1000 cc of uninvolved liver parenchyma as determined by the treating physician. * Determination that the patient is medically inoperable and/or unwilling to undergo liver resection in patients with colorectal carcinoma histology. * Provide informed written consent. * Willingness to return to Mayo Clinic Rochester for follow-up.

Exclusion criteria

* Pregnant women. * Nursing women. * Men or women of childbearing potential or their partners who are unwilling to employ adequate contraception. * Co-morbid systemic illnesses or other severe concurrent disease, defined as those which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens Immunocompromised patients (other than that related to the use of corticosteroids) including patients known to be HIV positive. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. * Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm =\< 7 days prior to registration. * Administration of chemotherapy within 2 wks prior to or 2 wks following SF-SBRT. * Prior radiation therapy to the liver Untreated malignant biliary obstruction (patients treated successfully with stenting are eligible). * Current diagnosis of hepatocellular carcinoma

Participant flow

Recruitment details

Three patients were recruited at Mayo Clinic between January 2010 and May 2010.

Pre-assignment details

This was a phase I/II trial. A total of 3 participants were accrued, all to the phase I portion. This trial was terminated due to poor accrual. No patients were accrued to the phase II portion. No results from the phase II portion are available.
