Abstract
Background: Hepatocellular carcinoma (HCC) is the sixth most prevalent cancer and the fourth leading cause of cancer death in the world. Aims: This study aimed to investigate the efficacy and safety of Lenvatinib + PD-1 inhibitor + TACEHAIC (LePTaHAIC) versus Sorafenib + TACE (SorTACE) for patients with intermediate and advanced HCC. Methods: In this retrospective study, patients diagnosed with BCLC stage B/C HCC were included. All patients were treated with LePTaHAIC (LePTaHAIC group) or SorTACE (SorTACE group) between September 2019 and September 2020. Outcomes, including progression-free survival (PFS), conversion surgical resection rate, objective remission rate (ORR), overall survival (OS), and treatment-related adverse events (AEs) were analyzed and compared between the two treatment modalities. Results: In total, 65 eligible patients were recruited, with 35 assigned to receive LePTaHAIC and 30 assigned to undergo SorTACE. Median PFS (11.4 vs. 5.13 months) and OS (26 vs. 10.08 months) in the LePTaHAIC group were significantly higher compared to the SorTACE group (both P < 0.0001). The ORR (mRECIST standard) of the LePTaHAIC group was markedly higher compared to the SorTACE group (71.4% vs. 40%, P = 0.01). In the LePTaHAIC group, 11 patients underwent surgical resection (BCLC stage B: n = 4, BCLC stage C: n = 7) and 3 patients achieved complete pathological remission (pCR), while one patient in the SorTACE group underwent surgical resection. The conversion surgical resection rate of the LePTaHAIC group was significantly higher compared to the SorTACE group [31.4% (11/35) vs. 3.3% (1/30), P = 0.004]. Patients with LePTaHAIC had more frequent grade 3-4 treatmentrelated AEs, especially thrombocytopenia, compared to the SorTACE group (22.9% vs. 3.3%, P = 0.02). Conclusion: LePTaHAIC exhibited acceptable toxic effects and improved survival compared to SorTACE in intermediate and advanced HCC.
