Tolerable Doses of Radiation in Patients with Liver Cancer or Metastases to the Liver in Patients with Good vs. Compromised Liver Function.
time frame: 6 years
Tumor Response to Doses of Radiation in Patients with Liver Cancer or Metastases to the Liver, in Patients with Good vs. Compromised Liver Function.
time frame: 6 years
All participants at least 18 years old.
Inclusion Criteria: 1. Hepatocellular carcinoma (as defined by biopsy or alpha-fetoprotein (AFP) greater than 1000ng/dL with appropriate imaging) or liver metastases from colorectal cancer or other tumor (as defined by biopsy or elevated CEA or a positive PET scan in conjunction with a mass on CT or MRI in a patient with previously resected cancer). Patients with at least one measurable liver lesion and no more than 3 are eligible if they meet all other eligibility criteria including the dose constraints on the composite plan. 2. ECOG performance status of 0-1. 3. Patients are not candidates for definitive surgical resection because of tumor location, hepatic function, or other medical or personal reasons. 4. Patients with HCC who are being considered for liver transplant may be entered as a bridge to transplant if it is considered by the transplant team that an ablative therapy would be of value while awaiting transplant. 5. If cirrhosis is present, patients will have Child-Pugh score of A or B (see Appendix A in the Master Protocol). 6. Patients will have tumors not optimally treated with radio-frequency ablation by interventional radiology, or by GI/transplant surgery. This could be for reasons of size, tumor location, or other reasons. 7. Ability to place fiducial markers in the vicinity of the tumor to allow for radiographic tracking of respiratory motion and tumor localization. Fiducial placement will generally be done by interventional radiology. 8. Estimates of hepatic tolerance must meet the criteria as defined in Section III. This eligibility will not be able to made definitively until the patient has agreed to participate. in the study and the appropriate scan analyses and dosimetry have been performed. No more than one decrement in dose from the planned dose level will be allowed for an individual patient because of exceeding the maximal liver doses before the patient is declared ineligible for study. 9. Adequate bone marrow and renal function as assessed by the following: - Absolute neutrophil count (ANC) > 1000/mm3 - Platelet count > 80,000/mm3 - Creatinine < 2.0 mg/dL OR Creatinine clearance > 45 mL/min based on Cockcroft-Gault formula). 10. Patients with extra hepatic metastatic disease are eligible if it is the opinion of the treating physician that local therapy to the liver may produce worthwhile clinical benefits 11. Patient is able to understand fully the potential risks and benefits of this approach and signs an appropriate informed consent. 12. Male and female of >18 years of age. Male or female patients capable of reproduction must agree to use medically acceptable methods of contraception, such as an intrauterine device, diaphragm, with spermicide, condom with spermicide or abstinence. Inclusion of females of childbearing potential requires a negative pregnancy test within 14 days prior to study initiation. Exclusion Criteria: 1. Child-Pugh Class C cirrhosis 2. Patients with clinically apparent CNS disease. 3. Medical or psychiatric illness that would not allow the patient to tolerate the proposed treatment including inability to lie flat for an extended period of time, severe claustrophobia or other reasons. 4. Uncontrolled or significant cardiovascular disease including: myocardial infarction within 6 months, uncontrolled angina within 6 months, Class III-IV New York Heart Association (NYHA) congestive heart failure, grade 3 cardiac valve dysfunction 5. Evidence of decompensated liver disease as evidenced by: clinically significant ascites refractory to diuretic therapy) evidence of hepatic encephalopathy, coagulopathy not corrected by conservative measures. 6. A history of CTC Grade 3 bleeding esophageal or gastric varices within the past 2 months. Prior variceal bleed permitted if patient has undergone banding or sclerotherapy and there has been no evidence of bleeding for 2 months. Patients at risk for varices (based on the following: known history of esophageal or gastric varices; evidence of hepatic cirrhosis and/or portal hypertension including biopsy-proven cirrhosis, hypersplenism, or radiographic findings of varices) will be screened for esophageal varices. If varices are identified that require intervention (banding), patient will not be eligible until varices adequately treated. 7. Prisoners or patients who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness must not be enrolled into this study. 8. Uncontrolled intercurrent illness. 9. Inability to comply with study and/or follow-up procedures. 10. A patient with Child-Pugh Class A will not be eligible for study if the liver dose constraint described in Section 3.2 cannot be met after two decrements in dose per fraction as described above. 11. A patient with Child-Pugh Class B will not be eligible for study if the liver dose constraint described in Section 3.2 cannot be met after two decrements in dose per fraction as described above.
|Official title||A Dose-finding, Safety and Preliminary Efficacy Study of Stereotactic Radiosurgery for Hepato-cellular Carcinoma and Metastatic Disease to the Liver.|
|Principal investigator||Joel Tepper, MD|
|Description||The CyberKnife system has been cleared by the U.S. Food and Drug Administration (FDA) to treat lesions, tumors and conditions anywhere in the body when radiation treatment is indicated. In order to treat tumors during the respiratory cycle (vs. increasing the margin of treatment around the tumor to compensate for movement or requiring the patient to breath hold during the delivery of each beam), the Synchrony™ option, a system option that enables dynamic radiosurgery during respiration, will be used. The purpose of this study is to determine a tolerable dose of radiation delivered by the CyberKnife in two groups of patients with hepatocellular carcinoma (HCC).Group 1: Patients with HCC and Childs A cirrhosis, and patients with colorectal liver metastases. Group 2: Patients with Childs B cirrhosis. Patients will be irradiated with radiation doses using the CyberKnife system in 3-5 radiation fractions using guidance from fiducials placed by interventional radiology. Treatments will be delivered with standard CyberKnife procedures to account for respiratory motion and set up variations. The fiducial location will be the prime determinant of the delivery site and respiratory motion and fiducial markers will be placed via percutaneous approach by interventional radiology.|
