TACE Combined with Lenvatinib and Camrelizumab for Unresectable Multiple Nodular and Large Hepatocellular Carcinoma (>5 cm).

Abstract

The incidence and mortality of hepatocellular carcinoma (HCC) had increased globally over the past decades. Previous studies found that transarterial chemoembolization (TACE) combined with lenvatinib had also shown efficacy in the unresectable HCC. We aimed to evaluate the safety and efficacy of TACE combined with lenvatinib and camrelizumab to treat unresectable multiple nodular and large HCC (>5 cm). Between November 2018 and June 2021, we retrospectively recruited 82 patients with unresectable multiple nodular and large HCC (BCLC stage B or C with a single nodular diameter of >5 cm). Of the patients who had not previously been treated, 33 patients received TACE + lenvatinib + camrelizumab (group A, TLC), and 49 patients treated with TACE + lenvatinib (group B, TLB) as the initial treatment. Related efficacy and safety results were recorded and assessed. The median follow-up periods of groups A and B were 14.5 ± 7.9 months (range, 3-36) and 12.5 ± 8.2 months (range, 3-32), respectively (P = 0.799). The progression-free survival (PFS) of groups A and B was 9.4 months and 5.9 months (P < 0.01), respectively, and overall survival (OS) was significantly longer in group A (16.4 months vs 11.0 months, P < 0.01). In group A, the local response rate (LRR) and disease control rate (DCR) were 51.5% and 81.8%, respectively, which was higher than the corresponding 46.9% and 77.6% observed in group B (P = 0.233; 0.429). Patients with BCLC B stage had better PFS and OS (P < 0.05). The BCLC stage was an independent factor that affected PFS and OS. There were no massive bleeding or treatment-related deaths. In patients with unresectable multiple nodular and large HCC (single nodular diameter of >5 cm), TACE combined with target therapy and immunotherapy is safe and effective.
