Table 2 Comparing key features of the LEGACY study and DOSISPHERE trial

LEGACY
DOSISPHERE
Study designMulti-center single-arm retrospective studyMulticenter randomized control phase ii trial
ObjectiveTo assess clinical outcomes of Y-90 glass microsphere treatment in patients with unresectable solitary HCC lesionsTo compare clinical outcomes of lobar TARE using 120 Gy (SDA) versus > 205 Gy (PDA) in patients with intermediate/advanced HCC
Inclusion criteriaUnresectable solitary lesions (≤ 8 cm); BCLC A or C (ECOG 0-1); Child-Pugh score A≥ 1 unresectable lesion ≥ 7 cm; BCLC A, B, or C
Exclusion criteriaPatients with vascular or extrahepatic disease, significant ascites, encephalopathy, or prior LRT, LT, resection, or systemic therapyPatients with micro-aggregate albumin (MAA) studies demonstrating poor tumor targeting
Overall survivalAt 3 yr, 86.6% for patients treated with TARE alone (median dose 410 Gy) and 92.8% for patients who down-staged via TAREOverall survival was improved in the personalized dosimetry group (26.6 mo vs 10.7 mo)
Downstaging21% successfully down-staged to LT; 6.8% to resection.36% patients in the PDA group and 3.5% (1/28) in the SDA group down-staged to resection1
