Radiotherapy Improves Survival in Difficult Liver Cancer Cases
Among patients with advanced hepatocellular carcinoma (HCC), and especially those with macrovascular invasion, stereotactic body radiation therapy (SBRT) appears to grant a survival benefit when added to systemic therapy. That was the finding from a phase 3 clinical trial presented at the annual meeting of the American Society for Radiation Oncology. For unresectable HCC or cases that cannot be treated with thermal ablation or regional therapy, the current standard of care is systemic therapy. When the study was conducted, the recommended therapy was the sorafenib, a tyrosine kinase inhibitor. But with the publication of the IMbrave 150 study in 2021, atezolizumab plus bevacizumab is now increasingly preferred by some oncologists.
@fritzi-0 the SHARP study found that sorafenib improved median survival, but it provided less benefit for patients with macrovascular invasion. Various studies have addressed the question of whether radiation could improve survival among this patient population, but results have not been encouraging. Direct comparisons between sorafenib and radiotherapy in the SARAH and SIRveNIB studies showed no significant differences in outcomes.
