Abstract

<b><i>Introduction:</i></b> Patients with liver cirrhosis develop thrombocytopenia and an increased risk of bleeding events after invasive procedures. Lusutrombopag, a thrombopoietin receptor agonist, can increase the platelet count. This study assessed whether lusutrombopag reduces the risk of hemoperitoneum following percutaneous radiofrequency ablation for hepatocellular carcinoma, compared with platelet transfusion. <b><i>Methods:</i></b> Participants in the present study comprised patients with severe thrombocytopenia (platelet count &lt;50,000/μL) enrolled between November 2012 and March 2020, excluding patients with idiopathic thrombocytopenia or anticoagulant use. Hemoperitoneum rate, hemostasis rate, hemoglobin reduction rate, rate of achieving a platelet count ≥50,000/μL, and increases in platelet count and factors contributing to hemoperitoneum were retrospectively analyzed. <b><i>Results:</i></b> This study enrolled 41 patients, comprising 18 patients administered lusutrombopag and 23 patients who received platelet transfusion. The major hemoperitoneum rate after RFA was tend to be lower in the lusutrombopag group (0%) than in the platelet transfusion group (21.7%). All of the major hemoperitoneum was observed in the platelet transfusion group. Hemoglobin reduction rate was lower in the lusutrombopag group (−0.17%) than in the platelet transfusion group (6.79%, <i>p</i> = 0.013). Hemostasis rate was lower in the lusutrombopag group (0%) than in the platelet transfusion group (21.7%, <i>p</i> = 0.045). The rate of achievement of platelet counts ≥50,000/μL the day after RFA was higher in the lusutrombopag group (100%) than in the platelet transfusion group (60.9%, <i>p</i> = 0.005). <b><i>Conclusion:</i></b> Lusutrombopag may be able to perform RFA more safely with respect to the hemoperitoneum caused by percutaneous radiofrequency ablation compared with platelet transfusion.
