Stereotactic Body Radiation Therapy (SBRT) for Patients With Hepatic Metastases

NCT ID: NCT01162278

Last Updated: 2020-08-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 60 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2010-07-31
• Study Completion Date: 2017-11-25

Brief Summary

Patients that have had staging studies identifying them as AJCC stage IV with up to five liver metastases will be considered for the study. About 60 patients will take part in this study at UT southwestern, Parkland Health & Hospital System, and Methodist Richardson Cancer Center. There are four dose cohorts for this study and each cohort will enroll a minimum of 7 to a maximum of 15 patients depending on tolerance of therapy. The treatment period will last for approximately 1 day and the follow-up portion of the study will last 5 years.

Detailed Description

If the patient has met all the eligibility criteria, they will be registered to the study After successful registration to the study and treatment planning session, patients will receive a single fraction of radiation. The total dose a particular patient receives will depend on the dose cohort they are enrolled into. Each treatment will last about one hour and will be given in a particular position to help guide the beams of radiation toward the cancer area. Although it is not mandatory, it is recommended that patients receive corticosteroid premedication (e.g. Decadron 4-10 m.g. p.o. in a single dose or equivalent) 15-60 minutes prior to each treatment for the intended purpose of modulating immediate acute inflammatory effects and providing anti-emetic support.

Study Groups

single fraction

Patients in each dose cohort will all be treated as a single group for dose escalation. The starting dose for the dose escalation portion will be 35Gy in one fraction. Subsequent cohorts of patients will receive an additional 5Gy per treatment to a maximum planned dose of 50Gy in one fraction.

Eligibility Criteria

Inclusion Criteria

• Signed study specific informed consent form.
• Age ≥ 18.
• Zubrod Performance Status 0-2.
• Biopsy proven primary malignancy.
• Predicted survival of >6 months.
• AJCC Stage IV disease with up to 5 liver metastases as seen on a contrast- enhanced CT, MRI or PET/CT.
• Ability to spare a critical liver volume as defined by the protocol constraints.
• Tumors must be located outside the Central Liver Zone defined by contouring the portal vein to its bifurcation + a 3-dimensional 2cm margin

Exclusion Criteria

• Patients with a history of prior irradiation or other treatment to the liver or abdomen who after the protocol treatment would have cumulative doses to the liver or other normal tissues greater than the protocol defined constraints.
• Need or plans for concomitant antineoplastic therapy (including surgery, cryotherapy, radiofrequency ablation, chemo-embolization, conventionally fractionated radiotherapy, brachytherapy, and hepatic artery chemotherapy) for the protocol treated lesions except at progression. Adjuvant systemic therapy before and after the protocol therapy per section 7.0, and surgery or other ablative therapy is allowed for lesions appearing after enrollment to this protocol as per section 8.0 is allowed.
• Germ cell or hematologic malignancies.
• History of Crohn's Disease or Ulcerative Colitis.

• Men and women of reproductive potential may not participate unless they agree to use an effective contraceptive method.
• Pregnant or lactating women.
• Severe, active co-morbidity
• Abnormal labs

• Minimum Eligible Age: 18 Years
