TheraSphere® Yttrium-90 microspheres for unresectable liver cancer that cannot be removed by surgery

You may qualify if

• Participants must have histologically or imaging-confirmed confirmed HCC.
• Group 1: Solitary tumor measuring 2-5 cm Or Group 2: 2-3 tumors each ≤ 3 cm in diameter.
• No prior therapy to target tumor(s).
• Not a candidate for surgical resection or thermal ablation after multidisciplinary assessment.
• Age ≥22 years.
• Eastern Cooperative Oncology Group (ECOG) performance status = 0 or 1.
• Demonstrated adequate organ function as defined below:; Total bilirubin ≤3.0 mg/dL, unless elevated due to Gilbert's syndrome and direct bilirubin is within normal limits.; aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) ≤5 X institutional upper limit of normal.; alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT) ≤5 X institutional upper limit of normal.; Creatinine Glomerular filtration rate (GFR) > 30 ml/min.
• Child-Pugh score ≤ B7
• Albumin-bilirubin (ALBI) score 1-2
• Participants who have received systemic therapy for HCC will be excluded from the trial.
• Ability to understand a written informed consent document, and the willingness to sign it.
• Human immunodeficiency virus (HIV)-infected participants on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
• Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.

You can't join if

• Macrovascular tumor invasion or infiltrative appearance of hepatocellular carcinoma.
• History of severe allergy to iodinated contrast agents despite appropriate premedication.
• Is currently receiving any other anti-cancer agents and any previous therapy with a device that uses Y90 as the radioisotope.
• Symptomatic heart failure or severe valvular insufficiency.
• Symptomatic pulmonary hypertension or lung disease.
• Symptomatic ascites.
• Severe uncontrolled coagulopathy International Normalized Ratio (INR) ≥ 3.0 or Platelet ≤ 20,000.
• Main vein thrombosis (portal vein, both bland and tumor thrombus). Note: Less than lobar portal vein thrombosis is allowable only if the thrombus is bland.
• Pregnant women are excluded from this study because TheraSphere emits radiation with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with TheraSphere, breastfeeding should be discontinued if the mother is treated with TheraSphere.
• Lung-shunt fraction (LSF) resulting in anticipated lung dose of >30 Gray (Gy).
• History of sphincterotomy, biliary-enteric anastomosis, or other biliary tract instrumentationExcept: Note: Prior cholecystectomy with or without bile duct exploration is permitted.
• Tumor perfused by extrahepatic collateral arteries.
• Prior partial hepatectomy.
• Psychiatric illness, other significant medical illness, or social situation which, in the investigator's opinion, would limit compliance or ability to comply with study requirements.
• History of or current extrahepatic cancer.
• Pulmonary insufficiency (defined by an arterial oxygen pressure (Pa,O2) of < 60 mmHg, or oxygen saturation (Sa,O2) of < 90%).
