Standard Versus Radiobiologically-Guided Dose Selected SBRT in Liver Cancer

Recruiting now · Not applicable

Conditions studied: Hepatocellular Carcinoma, Liver Metastases

In brief

Radiation is a standard treatment option for patients with liver cancer. Unfortunately, the tumour grows after radiation in many patients and radiation can harm normal tissues. A new treatment using a specialized radiation procedure called Stereotactic body radiotherapy (SBRT) may increase the chance to control liver cancer and reduce the chance of harm to normal tissues. SBRT allows radiation treatments to be focused more precisely, and be delivered more accurately than with older treatments. SBRT has become a routine treatment. Further research has found that specialized computer programs can possibly guide the selection of an appropriate SBRT dose. This is called radiobiological guidance. However, this has not yet been proven to improve outcomes and/or reduce toxicity. Therefore, the purpose of this study is to find out if SBRT at standard dose versus SBRT guided by radiobiological techniques is better for you and your liver cancer.

You may qualify if…

Eligible patients include patients with any of the following:
Primary hepatobiliary cancer confirmed pathologically or,
Non-lymphoma liver metastases confirmed pathologically or,
Radiographic liver lesions most consistent with metastases, in a patient with known pathologically proven non-lymphoma cancer and a previously negative CT or MRI of the liver or,
Hepatocellular carcinoma diagnosed with vascular enhancement of the lesion consistent with hepatocellular carcinoma, and with an elevated AFP, in the setting of cirrhosis or chronic hepatitis.
≤ 5 liver lesions measurable on a contrast-enhanced liver CT or MRI performed within 90 days prior to study entry.
Primary liver lesion or liver metastases measuring ≤ 25 cm.
Extrahepatic cancer is permitted if liver involvement is judged to be life-limiting
No contraindications to radiotherapy
Patient must be judged medically or surgically unresectable
Zubrod Performance Scale = 0-3
Age > 18
Systemic treatment including multikinase inhibitors and immunotherapy are allowed.
Multikinase inhibitors must be held 2 weeks prior to radiation and may be restarted 1 week post radiation.
Previous liver resection or ablative therapy is permitted
Chemotherapy must be completed at least 2 weeks prior to radiation therapy and not planned to be administered for at least 1 week (for anthracyclines at least 4 weeks) after completion of treatment.
Life expectancy > 6 months.
Women of childbearing potential and male participants must practice adequate contraception.

You may not qualify if…

Severe cirrhosis or liver failure defined as Child Pugh >B7
Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields
Severe, active co-morbidity, defined as limiting the patient's life to less than 6 months
Active hepatitis or clinically significant liver failure. Treated hepatitis is permitted.
Pregnancy, nursing women, or women of childbearing potential, and men who are sexually active and not willing/able to use medically acceptable forms of contraception; this exclusion is necessary because the treatment involved in this study may be teratogenic.
