Abstract

Hepatocellular carcinoma (HCC) is the most prevalent cancer of the hepatobiliary tract and the third leading cause of cancer-related mortality worldwide. Atezolizumab and bevacizumab combination is currently considered among the front-line treatment modalities for advanced unresectable HCC. Most studies examining this combination were focused on evaluating its effectiveness. Despite numerous case reports documenting some side effects, there is a limited number of large-scale studies assessing these side effects. In this article, we comment on the case report by Park et al published recently, reporting a fatal intra-tumoral hemorrhage in a patient with HCC who received systemic therapy in the form of the combination of atezolizumab and bevacizumab.

Core Tip: In this article, we comment on the case report by Park et al, published in the recently reporting a fatal intra-tumoral hemorrhage in a patient with hepatocellular carcinoma following successful treatment with atezolizumab/bevacizumab. Multiple predictive factors have been reported to be associated with such condition. They can be categorized as either patient-related (age, systemic hypertension, and use of anticoagulants), liver disease-related (degree of liver decompensation and thrombocytopenia), or tumor-related (portal vein thrombosis). However, future studies are required to assess the long-term safety of this combination in patients with hepatocellular carcinoma.
