Comparative effectiveness and safety of second-line therapies and dosing regimens for advanced hepatocellular...

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-associated death globally. Second-line therapies are crucial for improving survival and quality of life among individuals suffering from advanced HCC who have not responded to first-line therapies. This study sought to evaluate the safety and efficacy of different second-line therapies for advanced HCC by network meta-analysis. A network meta-analysis was carried out on 26 randomized controlled trials comprising 10 368 people suffering from advanced HCC. The treatments evaluated included cabozantinib, pembrolizumab, brivanib, apatinib, and other targeted therapies. The principal results assessed included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR). The evaluation also encompassed adverse events (AEs) as well as those classified as grade 3-4 AEs. Cabozantinib 60 mg once daily (QD) demonstrated the most significant improvement in OS [mean difference (MD) = 3.36, 95% confidence interval (CI) = 2.01, 4.70] and PFS (MD = 3.26, 95% CI = 2.59, 3.94), ranking highest among the therapies evaluated. Brivanib 800 mg once daily (OD) was most effective in terms of ORR [odds ratio (OR) = 7.13, 95% CI = 1.42, 35.88], while apatinib 750 mg QD ranked highest for DCR (OR = 3.92, 95% CI = 1.76, 8.71). Codrituzumab 1600 mg administered every 2 weeks demonstrated the most advantageous health profile, markedly decreasing AEs and instances of grade 3-4 AEs. Pembrolizumab 200 mg administered every 3 weeks indicated good effectiveness. Alongside a tolerable safety profile, indicating its potential as a reasonable second-line treatment option. Cabozantinib 60 mg QD and pembrolizumab 200 mg Q3W arise as the most suitable second-line therapies alternatives for advanced HCC, offering substantial improvements in survival and disease control with manageable adverse effects. These findings support the integration of both targeted and immune therapies in handling of advanced HCC.
