Brief Summary:
Patients with primary hepato-biliary malignancies or liver metastases from gastrointestinal cancer suffer substantial morbidity and mortality from their hepatic disease. Curative resection is feasible only for selected subgroups of patients. The majority of patients have unresectable and incurable disease. Aggressive arterial and systemic chemotherapy have been used in recent years with improved response and survival. However, a significant number of patients, at least one-third of patients with liver metastases from colorectal cancer and two-third or higher of unresectable hepatobiliary cancer, continue to die of liver failure from progressive disease in the liver. Percutaneous ethanol injections, chemoembolization, cryotherapy and thermal ablation using radiofrequency have been used to treat selected patients with smaller tumors (3-4 cm) in areas away from major blood vessels and the biliary tract. However, most unresectable liver cancers did not fit the criteria for these treatments. Therefore, other regional therapeutic option like external radiation therapy may be considered for local control in the liver or symptom palliation

Arm Intervention/treatment
Experimental: 1
Eligible patient will be treated with 48 Gy in 4 fractions encompassing the entire target lesion in 2 weeks with a minimum of 48 hours between each dose.
Radiation: Stereotactic Body Radiation Therapy
Radiation Dose: 48 Gy in 4 fractions in 2 weeks. A minimum of 48 hours should separate each treatment (e.g. every Tuesday and Friday). The dose is prescribed to the marginal isodose (80-90%) that encompasses the entire target lesion (GTV). Treatment will be delivered using a linear accelerator. For verification of the accuracy of these external skin fiducial markers, 10 patients will also have implanted internal gold coil markers. The implantable gold coil markers will be implanted into the liver in the proximity of the target lesions via a percutaneous transhepatic route under fluoroscopy guidance.

Primary Outcome Measures :
  1. Response rate to SBRT [ Time Frame: 3-6 Months ]

Secondary Outcome Measures :
  1. Treatment Related Toxicity [ Time Frame: 12 months ]
