Core Tip

Core Tip: Nowadays, the combination therapy of atezolizumab and bevacizumab is recommended as the first-line systemic treatment for advanced hepatocellular carcinomas. A global phase III study and recent real-world studies demonstrated rare life-threatening adverse events of atezolizumab and bevacizumab. However, our patient underwent acute respiratory distress syndrome and finally died three days after treatment. To the best of our knowledge, this is the first case of severe respiratory failure resulting in death with a very short interval from atezolizumab and bevacizumab administration. Therefore, we suggest close monitoring of lung toxicity after therapy.
