Liver transplantation for hepatocellular carcinoma: Where do we stand?

Table 2 Techniques employed for bridging or downstaging patients with hepatocellular carcinoma before liver transplantation and their efficacy

	Bridging	Downstaging
TACE	0-35% (39)	24%-77% (57)
Radioembolization	NA (49)	11%-43% (57)
RFA	16.8% (50)	NA
SBRT	16.7% (50)	NA
Resection	NA (40, 42)	NA
Combined approach (TACE + RFA or radioembolization)	NA	56% (58)

Bridging column: Percentages (when present) indicate the drop-out rate from list despite bridging therapy; corresponding reference between commas. Downstaging column: Percentages (when present) indicate the success rate with downstaging; corresponding reference between commas. TACE: Trans-arterial chemo-embolization; RFA: Radiofrequency ablation; SBRT: Stereotactic body radiotherapy; NA: Not assessed.
