Clinical Trial Summary

This is a pilot study where patients with Hepatocellular Carcinoma (HCC) that have failed Transarterial Chemoembolization (TACE) will be treated with Stereotactic Body Radiation Therapy (SBRT). The focus of the study will be to evaluate safety and efficacy in our population of patients.

Intervention

Radiation:
• SBRT
SBRT will be prescribed according to the Radiation Therapy Oncology Group (RTOG) 1112 protocol using Mean Liver Dose (MLD) as parameter. MLD will be calculated using Liver minus Gross Tumor Volume (GTV). Prescription dose will follow the scheme below: Prescription dose(Gy) / (MLD) (Gy) 50 / 13 45 / 15 40 / 15 35 / 15.5 30 / 16 27.5 / 17 If the dose constraints cannot be met, prescription will be according to the level immediately bellow. Treatment will be delivered in 5 fractions in consecutive working days

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Local Progression Free Survival	Local Progression Free Survival will be measured on triphasic Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) when clinically indicated.; The exam will be performed every 3 months after the end of treatment. The tumor response will be measured according to the modified RECIST (mRECIST) directed to the HCC study.; Local Progression Free Survival will be defined as increase of 20% in the sum of all diameters of the treated lesions.; Time-to-event will be counted from the initiation of SBRT	5 years
Secondary	Distant Progression Free Survival	Distant Progression Free Survival will be measured on triphasic Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) when clinically indicated.; The exam will be performed every 3 months after the end of treatment. The tumor response will be measured according to the modified RECIST (mRECIST) directed to the HCC study.; Distant Progression Free Survival will be defined as the appearance of a new hepatic lesion, tumoral thrombus or distant metastases.; Time-to-event will be counted from the initiation of SBRT	5 years
Secondary	Toxicity	Toxicity will be evaluated according to the Common Terminology Criteria for Adverse Events version 4.0 (CTCAE v.4.0). Toxicity will be evaluated weekly during treatment, monthly in the first 3 months after treatment and every 3 months after.; Acute Toxicity will be defined as toxicity that develops within the first 3 months after initiation treatment.; Chronic Toxicity will be defined as toxicity that develops after 3 months of initiation of treatment.	5 years
Secondary	Overall Survival	Time-to-event will be counted from the initiation of SBRT	5 years
