Association of Albumin-Bilirubin Grade and Sequential Treatment with Standard Systemic Therapies for Advanced Hepatocellular Carcinoma: A Retrospective Cohort Study Using a Japanese Administrative Database.

ABSTRACT

BACKGROUND: Evidence about the relationship between albumin-bilirubin (ALBI) grade and sequential systemic therapy for advanced hepatocellular carcinoma in real-world Japanese clinical practice is limited. OBJECTIVE: The objective of this study was to investigate ALBI grades and sequential treatment for advanced hepatocellular carcinoma in Japanese clinical practice. METHODS: We conducted a retrospective cohort study using a Japanese hospital-based administration database to assess treatment sequence in patients with confirmed advanced hepatocellular carcinoma and first prescription (index line) of lenvatinib (July 2014-June 2019; N = 1558) or sorafenib (July 2014-June 2016 [sorafenib-A; N = 1511] or June 2017-June 2019 [sorafenib-B; N = 1276]). Transition to subsequent line was assessed in patients who completed the index line without transarterial chemoembolization. The ALBI grade and sequential treatment relationships were analyzed in patients with baseline and/or end of index line ALBI scores. RESULTS: Transition to a subsequent line was low (sorafenib-A [n = 1320] 12.6%; sorafenib-B [n = 1049] 40.7%; lenvatinib [n = 786] 27.2%). In patients with baseline ALBI data (combined cohorts; n = 385), overall treatment duration was shorter in those with baseline ALBI grade 2b or 3 vs grade 1 or 2a (median 7.1, 6.7, 4.5, and 3.0 months for grades 1, 2a, 2b, and 3, respectively). In patients with baseline and end of index line ALBI data (combined cohorts; n = 222), ALBI grade worsened during index line regardless of baseline grade. Of these patients in the sorafenib-B or lenvatinib cohorts who completed the index line without transarterial chemoembolization (n = 120), transition to a subsequent line was higher with the end of index line grade 1/2a (66.7/68.4%) than with grade 2b/3 (34.0/11.1%). CONCLUSIONS: Adequate liver function, indicated by ALBI grade, at the start and end of first-line treatment is associated with successful sequential therapy in Japanese clinical practice.
