Patients who had received TheraSphere
- Alternative two-compartment TheraSphere dosimetry methodology [ Time Frame: Baseline ]Normal tissue absorbed dose using pre-procedural 99mTc MAA (Technetium-99m Macroaggregated albumin) SPECT (Single-photon emission computer tomography) or SPECT/CT (Single-photon emission computer tomography/Computer Tomography) imaging, to allow the mean absorbed normal tissue dose corresponding to a ≤15% probability of Common Toxicities Criteria for Adverse Events (CTCAE) grade 3 or higher hyperbilirubinemia (in the absence of disease progression) to be calculated.
- Tumor dose [ Time Frame: Baseline ]Tumor dose (to tumors ≥3 cm) using pre-procedural 99mTc MAA SPECT or SPECT/CT imaging.
- Serious adverse events [ Time Frame: 3 months ]All serious adverse events (SAEs) assessed as related or potentially related to TheraSphere
- Specific non-serious adverse events (AEs) assessed as related or potentially related to the dose of TheraSphere [ Time Frame: 3 months ]
Specific non-serious adverse events (AEs) assessed as related or potentially related to the dose of TheraSphere, comprising of any of the following events:
- Clinical laboratory assessments [ Time Frame: 6 weeks and 3 months ]Clinical laboratory assessments
- Objective response (OR) of the target lesion and non-target sesions [ Time Frame: 3 months and 6 months ]Objective response (OR) of the target lesion (single largest lesion) and non-target lesion(s) after TheraSphere administration by Modified Response Evaluation Criteria in Solid Tumors (mRECIST) and Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
- Volume changes [ Time Frame: 3 and 6 months ]Volume changes (i.e., perfused liver volume and non-perfused liver volume) from baseline afterTheraSphere administration.
- Overall Survival (OS) [ Time Frame: 6 months ]Overall Survival (OS)
- Target Alpha fetoprotein (AFP) response [ Time Frame: 6 weeks and 3 months ]
Target Alpha fetoprotein (AFP) response (defined as a ≥50% decrease in AFP levels for patients with a baseline AFP level of
- Albumin-bilirubin (ALBI) score [ Time Frame: 6 weeks and 3 months ]Albumin-bilirubin (ALBI) score, a measure of liver function for HCC patients after TheraSphere administration.
- Dose to Portal Vein Thrombosis (PVT) [ Time Frame: baseline, 90 days, 180 days ]Dose to Portal Vein Thrombosis (PVT) based upon pre- and postprocedure imaging (if PVT present).
- Dosimetric analysis time [ Time Frame: baseline ]Dosimetric analysis time (i.e., workflow).
- Dose accuracy [ Time Frame: baseline ]Dose accuracy based upon phantom imaging studies.
- Dose reproducibility [ Time Frame: baseline ]Measurement of inter-observer agreement based on a round robin review of the same 20 patients obtained from a minimum of 8 users (with each user at a different site) and an exploratory assessment of intra-observer agreement based on a review of 10 patients by a minimum of 8 users at least 2 weeks apart. The 10 patients for the intra-observer agreement will be a subset of the patients included in the assessment of inter-observer agreement.
