Core Tip

Core Tip: Recurrent hepatocellular carcinoma (HCC) with inferior vena cava tumor thrombus (IVCTT) is a great challenge for oncologists and has a poor prognosis. The safety and efficacy of programmed cell death ligand 1 inhibitors are still unknown. To the best of our knowledge, the first case is the first report of successful treatment of recurrent and metastatic HCC with inferior vena cava tumor thrombus with atezolizumab. We reported two other cases of HCC with IVCTT at the first diagnosis, for which patients were treated with a programmed cell death protein 1 inhibitor after surgery or recurrence, and both patients achieved a good outcome. Anti-programmed cell death ligand 1 therapy in HCC patients with IVCTT and metastasis is associated with relatively good patient outcomes.
