Abstract
Transarterial chemoembolization (TACE) is the standard of care for intermediate stage hepatocellular carcinoma (HCC). We aimed to identify unsuitable cases who were at risk of ALBI-grade migration by TACE. Consecutive 531 BCLC-B HCC patients undergoing TACE were reviewed, and factors associated with ALBI-grade migration were analyzed. There were 129 (24.3%) patients experienced acute ALBI-grade migration after TACE, and 85 (65.9%) out of the 129 patients had chronic ALBI-grade migration. Incidences of acute ALBI-grade migration were 13.9%, 29.0% for patients within or beyond up-to-7 criteria (p < 0.001) and 20.0%, 36.2% for patients within or beyond up-to-11 criteria (p < 0.001), respectively. HBV infection, tumor size plus tumor number criteria were risk factors associated with acute ALBI-grade migration. Bilobar tumor involvement was the risk factor of chronic ALBI-grade migration in patients with acute ALBI-grade migration. Up-to-eleven (p = 0.007) performed better than up-to-seven (p = 0.146) to differentiate risk of dynamic ALBI score changes. Moreover, ALBI-grade migration to grade 3 has adverse effect on survival. In conclusion, tumor burden beyond up-to-eleven was associated with ALBI-grade migration after TACE, indicating that up-to-eleven can select TACE-unsuitable HCC patients who are at risk of liver function deterioration.
