Hepatocellular carcinoma (HCC) has become a growing health concern globally. Microvascular invasion and high tumor burden are key factors limiting the cura
This case study reports a 49-year-old woman who was diagnosed with China Liver Cancer Staging (CNLC) IIIa HCC and > 15 cm tumor diameter. Initially, due to insufficient future liver remnant and vascular invasion, the tumor was unresectable; however, radical hepatectomy was performed after successful conversion therapy with SIRT using yttrium-90 (90Y) resin microspheres followed by hepatic arterial infusion chemotherapy (HAIC) with tyrosine kinase inhibitor (TKI) and anti-programmed death-1 (PD-1) antibody. SIRT using 90Y resin microspheres was given by the right hepatic artery and chemoembolization was simultaneously performed in the tumor’s feeding vessels from the right diaphragmatic artery. HAIC was followed every three weeks with lenvatinib and tislelizumab. At 4 months post-SIRT, the tumor was downstaged to CNLC Ib and the patient successfully under
This case study provides evidence for an integrated treatment strategy combining SIRT and HAIC with TKI and anti-PD-1 antibodies for patients with large HCC and microvascular invasion. Further confirmatory trials are re
Core Tip: Although selective internal radiation therapy (SIRT) has been used to treat unresectable hepatic cancers for more than 20 years, it is mainly employed to treat patients with ≤ 8 cm tumor size. This research reports a hepatocellular carcinoma patient with > 15 cm hepatic mass, microvascular invasion, and China Liver Cancer Staging (CNLC) IIIa who received radical hepatectomy after successful conversion therapy with SIRT using yttrium-90 resin microspheres followed by hepatic arterial infusion chemotherapy using anti-programmed death-1 antibody and tyrosine kinase inhibitor. After 4 months of SIRT, the tumor was downstaged to CNLC Ib and the future liver remnant increased from 434 mL to 802 mL.
