Hepatic Function during Repeated TACE Procedures and Prognosis after Introducing Sorafenib in Patients with...

We evaluated the relationship of hepatic function with repeated transarterial catheter chemoembolization (TACE) and prognosis after sorafenib treatment in various patient cohorts.

Study 1 comprised of 212 Barcelona clinic liver cancer stage-B (BCLC-B) HCC patients classified as Child-Pugh A (CP-A) and who had received repeated TACE treatments (r-TACE) (naïve:recurrence = 66:146). Study 2 comprised of 435 patients with unresectable HCC classified as CP-A in who sorafenib was introduced (naïve:recurrence = 37:398; CP score 5:6 = 282:153; macro-vessel invasion [MVI]+: extrahepatic metastasis [EHM]+ both negative = 124:226:143). Changes in hepatic function along with CP and albumin-bilirubin (ALBI) score/grade during r-TACE in Study 1, and prognosis after introducing sorafenib in Study 2 were evaluated.

Hepatic function worsened to CP-B in 9-14% with each TACE procedure, while 18-21% had a change of classification from ALBI-1 to ALBI-2. When the prognosis of patients with the best CP score of 5 was analyzed, those with ALBI-1 (n = 154) had a better outcome than those with ALBI-2 (n = 128) (MST 17.5 vs. 9.9 months; p = 0.01), while ALBI-1 (n = 43) patients also showed a better outcome than ALBI-2 (n = 34) patients with a CP score of 5 without MVI/EHM (MST: 17.5 vs. 10.0 months; p = 0.029). The Akaike's Information criterion for ALBI-grade (MST: grade 1 vs. 2 = 16.9 vs. 10.4 months; p = 0.001) was also better than that for CP (MST: score 5 vs. 6 = 14.4 vs. 10.5 months; p = 0.003) (3195.6 vs. 3197.5) in all 435 patients.

The rate of patients with downgraded hepatic function during r-TACE, especially with regard to ALBI-grade, was not low. ALBI-grade was shown to be a better hepatic function assessment tool than CP in patients receiving sorafenib treatment. Strict judgment of TACE-refractory status in patients with unresectable HCC is needed to improve prognosis before downgrading the hepatic function.
