The AMARA (As Much As Reasonably Achievable) Study

Summary

Subjects with large inoperable liver tumors defined as at least 1 lesion larger than 5cm in maximum diameter. For the purposes of the present study, we define the AMARA principle in intensified regional TARE as a planned irradiated tumor dose \>200Gy by the partition model. The purpose of the study is to evaluate the safety and efficacy of Y90 high dose radioembolization for the management of large inoperable liver tumors. In addition, to correlate the safety and efficacy with the post-treatment dosimetry analysis (by MIM Software Inc) based on 90Y-PET/CT imaging.
