Key Takeaway
Consider immune-based combinations over monotherapies for improved survival in advanced hepatocellular carcinoma.

This systematic review and network meta-analysis evaluated the efficacy of immune-based combinations, including ICI-anti-angiogenic and dual-blockade regimens, against monotherapies such as sorafenib in patients with advanced hepatocellular carcinoma. The analysis included 8,138 patients to compare overall survival (OS) and other clinical outcomes.

The study found that sintilimab plus IBI305 demonstrated a significant improvement in OS compared to sorafenib (HR = 0.57; SUCRA = 0.94). Similarly, camrelizumab plus rivoceranib showed improved OS over sorafenib (HR = 0.62; SUCRA = 0.89). While first-line settings compared to sorafenib showed a significant improvement in OS (HR = 0.74; 95% CI: 0.65-0.83), the second-line setting did not show a significant difference or was worse than first-line (HR = 1.09; 95% CI: 0.90-1.30; P = 0.0006).

A primary limitation noted was the lack of direct comparisons for some treatments, which necessitated the use of network meta-analysis. From a clinical perspective, these findings support a tailored continuum of care to guide optimal sequencing based on both efficacy and safety profiles. ICI monotherapy or dual-blockade showed better tolerability than TKI-based combinations, which significantly increased Grade 3 or higher treatment-related adverse events.

How this fits prior evidence

This finding extends the evidence that combination immunotherapy and targeted therapy regimens show favorable survival outcomes versus monotherapies in unresectable hepatocellular carcinoma. It specifically quantifies the benefit of certain combinations like sintilimab plus IBI305 (HR = 0.57) and camrelizumab plus rivoceranib (HR = 0.62). The results also clarify that first-line settings provide a more significant survival advantage than second-line settings, addressing gaps in optimal treatment sequencing.

Living with advanced hepatocellular carcinoma (HCC) is a heavy burden, and finding the right treatment path is vital. A large study of over 8,000 patients looked at different ways to treat this type of liver cancer, comparing several drug combinations against standard treatments like sorafenib.

The research found that certain immune-based combinations performed better than older standards. Specifically, combining drugs like sintilimab with IBI305 or camrelizumab with rivoceranib showed improved survival rates compared to sorafenib. However, the timing of these treatments matters. Patients who received these advanced therapies as a first-line treatment saw significant improvements in survival, while those receiving them as a second-line treatment did not show the same level of benefit.

Safety is also a major factor in choosing a path forward. While immune-based combinations showed better tolerability for patients, some other types of drug combinations were linked to more severe side effects. Because this study relied on indirect comparisons for some treatments, the exact results can vary depending on the specific drugs used. Doctors can use these findings to help create a personalized care plan based on both effectiveness and how well a patient can tolerate the treatment.

What this means for you:
Early use of certain immune-based drug combinations shows better survival for advanced liver cancer patients.

Common questions

Which treatments showed the best results for liver cancer?

The study found that certain immune-based combinations performed better than sorafenib. Specifically, sintilimab plus IBI305 and camrelizumab plus rivoceranib both showed improved survival rates compared to the standard sorafenib treatment.

Does it matter when these treatments are started?

Yes, timing is important. Patients who received immune-based combinations as a first-line treatment saw significant improvements in survival. However, patients who received these same treatments as a second-line treatment did not show the same level of improvement.

Are these new treatments safe for patients?

The study found that immune-based monotherapies and dual-blockades were better tolerated by patients. In contrast, some other combinations significantly increased the rates of severe side effects, known as Grade 3 or higher treatment-related adverse events.

BackgroundWith the rapid introduction of immune checkpoint inhibitors (ICIs) for advanced hepatocellular carcinoma (HCC), optimal treatment sequencing remains unclear. Lacking direct comparisons, we aimed to evaluate the efficacy and safety of systemic therapies across first- and second-line settings.MethodsA frequentist network meta-analysis (PROSPERO: CRD420261296427) was performed using phase III RCTs from PubMed, Embase, Cochrane, and Web of Science (up to January 2026) evaluating systemic HCC therapies. The primary endpoint was overall survival (OS); secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and Grade ≥3 treatment-related adverse events (TRAEs). Subgroup analysis compared treatment-naïve versus refractory populations.ResultsTwelve RCTs comprising 8,138 patients were analyzed. For OS, ICI-anti-angiogenic combinations ranked highest, notably sintilimab plus IBI305 (HR = 0.57 vs. sorafenib; SUCRA = 0.94) and camrelizumab plus rivoceranib (HR = 0.62 vs. sorafenib; SUCRA = 0.89). Combinations consistently outperformed monotherapies in PFS and ORR. Crucially, subgroup analysis revealed a statistically significant difference in the magnitude of survival benefit between first-line (HR = 0.74, 95% CI: 0.65–0.83) and second-line settings (HR = 1.09, 95%CI: 0.90–1.30) when compared to sorafenib (P = 0.0006). Regarding safety, ICI monotherapy/dual-blockade (e.g., pembrolizumab, nivolumab + ipilimumab) demonstrated better tolerability, whereas TKI-based combinations significantly increased Grade ≥3 TRAE rates.ConclusionICI-based combinations offer the most robust survival benefits in HCC via pharmacodynamic synergy, albeit with higher cumulative toxicity. The differing magnitude of survival benefit between first- and second-line settings when compared to sorafenib highlights their distinct clinical contexts. These findings support a tailored continuum of care, guiding optimal sequencing based on pharmacological efficacy and safety profiles.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420261296427, identifier CRD420261296427.
