Popis: This retrospective study aimed to evaluate the impact of atezolizumab plus bevacizumab–transcatheter arterial chemoembolization (TACE) sequential therapy in unresectable hepatocellular carcinoma (HCC), especially in patients with intermediate-stage HCC. A total of 212 patients were enrolled and categorized into the Atez/Bev-TACE sequential therapy (n = 23) or Atez/Bev monotherapy group (n = 189) between 2020 and 2024. Of these, patients with intermediate-stage HCC were categorized into the Atez/Bev-TACE sequential (n = 18) or Atez/Bev monotherapy group (n = 91). The best objective response rate, disease control rate, and median progression-free survival (PFS) after TACE were 73.9%, 82.6%, and 6.1 months, respectively. The PFS after TACE was significantly higher in the Atez/Bev sequential therapy group than in the no-Atez/Bev-administration group after TACE (6.9 months vs. 5.0 months, p = 0.025). The median overall survival (OS) was significantly higher in the Atez/Bev-TACE sequential therapy group than in the Atez/Bev monotherapy group for intermediate-stage HCC (34.9 months vs. 17.8 months; p = 0.016). Independent factors associated with OS were low alpha-fetoprotein levels, modified albumin–bilirubin 1 or 2a levels, and Atez/Bev-TACE sequential therapy. Atez/Bev-TACE sequential therapy improved prognosis compared with Atez/Bev monotherapy in patients with intermediate-stage HCC. Moreover, Atez/Bev should be readministered after TACE.
