Systemic therapy is the mainstay of treatment for patients with unresectable hepatocellular carcinoma (HCC). This month we will review publications that report outcomes of patients treated with immunotherapy.
Verset and colleagues reported results from cohort 2 of the phase 2 KEYNOTE-224 trial, which investigated first-line pembrolizumab in patients with unresectable HCC. Fifty-one patients were included in cohort 2. The overall response rate (ORR) was 16% [95% CI 7-29] and was similar across key subgroups. Median duration of response was 16 months (range 3-24+), and disease control rate was 57%. The median progression-free survival (PFS) was 4 months (95% CI 2-8), and median time to progression was 4 months (95% CI 3-9). Median overall survival (OS) was 17 months (95% CI 8-23). Grade ≥ 3 treatment-related adverse events occurred in 16% of patients. The authors concluded that pembrolizumab is an effective treatment for patients with unresectable HCC and should be studied further in this setting.
Immunotherapy combinations are frequently used in the first-line setting for patients with unresectable HCC. In the past, many patients received immunotherapy in the second- or third-line settings. Sharma and coworkers reported patient outcomes following immunotherapy (immune checkpoint inhibitors, ICI). This retrospective, multicenter study examined anticancer treatment received after ICI treatment and assessed the impact of systemic treatment on post-ICI survival. A total of 420 patients with HCC were included. Most patients (n = 371; 88.3%) had received at least one prior treatment for HCC before ICI, including at least one line of systemic therapy (n = 289; 68.8%), with most receiving sorafenib (n = 237; 56.4%). Following immunotherapy, 31 (8.8%) died, 152 (36.2%) received best supportive care, and 163 patients (38.8%) received subsequent anticancer therapy. Tyrosine kinase inhibitors (TKI; n = 132; 80.9%), mostly sorafenib (n = 49; 30.0%), were the most common post-ICI therapy, followed by external beam radiotherapy (n = 28; 17.2%), further immunotherapy (n = 21; 12.9%), locoregional therapy (n = 23; 14.1%), chemotherapy (n = 9; 5.5%), and surgery (n = 6; 3.6%). Post-ICI therapy was associated with longer median OS compared with best supportive care (12.1 vs 3.3 months; hazard ratio [HR] 0.4; 95% CI 2.7-5.0). No difference in OS was noted if TKI were administered before or after ICI. The authors concluded that post-ICI therapy is associated with OS greater than 12 months, suggesting a role for therapeutic sequencing. OS from TKI therapy was similar to that reported in registration studies, suggesting preserved efficacy following ICI.
Finally, Ahn and colleagues looked at racial disparities in patients with HCC. In this report, 3248 (81.4%) patients received chemotherapy and 742 (18.6%) patients received immunotherapy as a first-line treatment. Immunotherapy was associated with improved OS compared with chemotherapy (adjusted HR 0.76; 95% CI 0.65-0.88). There were racial and ethnic disparities in access to immunotherapy, with Hispanic (adjusted odds ratio [aOR] 0.63; 95% CI 0.46-0.83) and Black (aOR 0.71; 95% CI 0.54-0.89) patients less likely to receive immunotherapy compared with White patients.
