The purpose of this protocol is to provide TheraSphere treatment for patients with liver cancer who cannot be treated by surgery. The effect on the tumor and any side effects of TheraSphere treatment will be examined. This study will provide supervised and limited access to TheraSphere treatment at University California Irvine Medical Center.

TheraSphere is a medical device containing yttrium-90 (Y-90), a radioactive material that has been used previously in the treatment of liver tumors. When Y-90 is incorporated into very tiny glass beads (TheraSphere), it can be injected to the liver through blood vessels supplying the liver. This allows a large dose of radiation to be delivered to the tumor with less risk of toxic effects from radiation to other parts of the body or to healthy liver tissue. The radiation from TheraSphere is contained within the body and becomes minimally active within 7 days after treatment due to physical decay. The glass beads remain in the body, but do not cause any health problems. TheraSphere has been approved for use in the treatment of liver cancer in the United States by the Food and Drug Administration on a limited basis.

Primary Outcome Measures:
  • The protocol allows for prospective collection of data. There is no randomization to an alternative form of therapy. However, we measure tumor response after treatment based on CT scans and tumor markers. [ Time Frame: Every 3-6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evaluate for side effects [ Time Frame: Every 1-2 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 130
Study Start Date: May 2002
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: TheraSphere® treatment

TheraSphere® treatment will be performed in the outpatient setting.

Within two weeks (14 days) of initial treatment, a catheter will be placed and liver angiography will be performed to confirm eligibility, followed by a Technetium-99 Macroaggregated Albumin (Tc-99m MAA) study. If either study indicates an uncorrectable risk of flow to the gastrointestinal organs or risk of shunting to the lungs, TheraSphere® treatment will not be administered. In this event, the patient will receive alternative treatment (chemoembolization) or no treatment, as previously defined in the treatment plan. If the patient remains eligible, TheraSphere® will be administered within two weeks.

All patients will be evaluated at 30 days post-treatment to assess clinical experience and adverse experiences. Subsequently, patient status will be followed via communication with the referring oncologist to determine disease status and survival. Survival surveillance will continue up to 24 months.

Device: TheraSphere
Given IV

Detailed Description:

This protocol provides TheraSphere treatment for patients with liver cancer who cannot be treated by surgery. Patients with hepatocellular carcinoma will be evaluated for eligibility for this treatment with the following: physical examination, medical history, blood tests requiring approximately 2 tablespoons of blood, EKG, CT or MR of chest to examine lungs, CT or magnetic resonance (MR) of abdomen to evaluate liver, stomach and intestines, and bone scan to rule out spread of disease to bones. If eligible on initial screening, patients will proceed to a second stage of screening, including an hepatic angiogram to confirm treatment can be provided safely and to highlight the blood vessels supplying the liver, and a nuclear medicine study (Tc-99m MAA scan) to display the blood flow to the lungs, stomach and intestines.

When it is determined treatment can be delivered safely, patients will receive TheraSphere via the hepatic artery through blood vessels supplying the liver on an outpatient basis.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed diagnosis of intrahepatic carcinoma. The histopathology confirmation criterion may be waived in patients with a radiographically identifiable liver mass, known laboratory or clinical risk factors for cancer or elevated tumor markers such as Alpha-fetoprotein assay (AFP) (clinical diagnosis).
  • The cancer must be unresectable.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status Score 0 - 2
  • Age ≥ 18 years.
  • Able to comprehend and read the study information sheet in accordance with institutional and federal guidelines.

Exclusion Criteria:

  • Any pre-treatment laboratory findings within 15 days of treatment demonstrating:

    • Absolute granulocyte count ≤ 1,500/ul
    • Platelet count ≤ 75,000/μl
    • Serum creatinine ≥ 2.0 mg/dl
    • Serum bilirubin ≥ 2.0 mg/dl
  • Any of the following contraindications to angiography and selective visceral catheterization:

    • History of severe allergy or intolerance to any contrast media, narcotics, sedatives, or atropine
    • Bleeding diathesis, not correctable by usual forms of therapy
    • Severe peripheral vascular disease that would preclude catheterization.
  • Portal hypertension with portal venous shunt away from the liver.
  • Evidence of potential delivery of greater than 16.5 millicurie (mCi) (30 Gy absorbed dose) of radiation to the lungs on either: 1) first TheraSphere administration; or 2) cumulative delivery of radiation to the lungs > 30 Gy over multiple treatments.
  • Evidence of any detectable Tc-99m MAA flow to the stomach or duodenum, after application of established angiographic techniques to stop such flow.
  • Significant extrahepatic disease representing an imminent life-threatening outcome.
  • Severe liver dysfunction or pulmonary insufficiency.
  • Active uncontrolled infection.
  • Significant underlying medical or psychiatric illness.
  • Pregnant women may not participate.
