Efficacy and Safety of Arterial Infusion Chemotherapy in Patients with Advanced Hepatocellular Carcinoma and Child-Pugh Class B: A Retrospective Cohort Study

Abstract

<b><i>Introduction:</i></b> Although many treatment options are available for patients with advanced hepatocellular carcinoma (HCC) and Child-Pugh (CP) class A, those for patients with CP class B remain limited. We aimed to assess the safety and efficacy of hepatic arterial infusion chemotherapy (HAIC) using 5-fluorouracil and cisplatin in patients with advanced HCC and CP class B. <b><i>Methods:</i></b> Sixty patients who received HAIC with 5-fluorouracil and cisplatin at Kurume Chuo Hospital between April 2012 and March 2021 were recruited. Cisplatin (30 mg administered over 2 h) and 5-fluorouracil (1,250 mg, 72-h constant infusion) were administered to the tumor-feeding artery every 2 weeks. The primary endpoint was overall survival (OS), while the secondary endpoints were progression-free survival and adverse effects. <b><i>Results:</i></b> Among the 60 patients, CP class A and class B were noted in 30 patients each. OS did not significantly differ between the two classes. After 4 weeks of HAIC with 5-fluorouracil and cisplatin, 12 patients in the class B group exhibited improved CP scores (CPSs) relative to those at the start of treatment. There was a significant difference in OS between patients whose CPSs had improved and those whose scores remained unchanged or had worsened. <b><i>Conclusions:</i></b> HAIC using 5-fluorouracil and cisplatin is effective and safe for patients with CP class B, and improvements in CPSs after 4 weeks of this therapy may represent a predictive marker of treatment efficacy regardless of pretreatment CPS in patients with CP class B.
