Abstract | BACKGROUND: METHODS: In this open-label, single-center, randomized trial (ClinicalTrials.gov identifier: NCT04127396), participants with previously untreated HCC and type I-IV PVTT were randomized 1:1 to receive TACE plus lenvatinib (arm L; orally once daily, 12 mg for body weight ≥60 kg or 8 mg for body weight <60 kg) or TACE plus sorafenib (arm S; 400 mg orally twice daily in 28-day cycles). The primary end point was time-to-progression ( TTP; time from randomization to disease progression) and secondary end points included objective response rate and toxicity. Prognostic factors were evaluated using a multivariable Cox proportional hazards model. RESULTS: Between December 30, 2018 and May 31, 2020, 64 patients were randomized (arm L, n = 32; arm S, n = 32); most patients had type I/II PVTT (71.9%), and the median target tumor diameter was 9.8 cm (range, 3.8-21.8). After a median follow-up of 16.1 months, patients in arm L had a higher median TTP (4.7 vs 3.1 months; hazard ratio [HR], 0.55; 95% CI, 0.32-0.95; P = .029) and objective response rate (53.1% vs 25.0%, P = .039) versus arm S. Multivariable analysis showed that TACE plus lenvatinib was significantly associated with higher TTP versus TACE plus sorafenib (HR, 0.50; 95% CI, 0.28-0.90; P = .021). Comparable safety profiles were observed in arms L and S. CONCLUSIONS: TACE plus lenvatinib was safe, well tolerated, and had favorable efficacy versus TACE plus sorafenib in patients with advanced HCC with PVTT and large tumor burden. LAY SUMMARY:
Hepatocellular carcinoma with portal vein tumor thrombus has a poor prognosis. In addition, most phase 3 trials of drugs for hepatocellular carcinoma exclude patients with major portal vein invasion, and treatment options for these patients are limited. Transarterial chemoembolization has shown promising efficacy in these patients, especially in combination with systemic treatment or radiotherapy. However, transarterial chemoembolization plus lenvatinib has not been investigated in this setting. This open-label, single-center, randomized trial showed that transarterial chemoembolization plus lenvatinib is safe, well tolerated, and has favorable efficacy versus transarterial chemoembolization plus sorafenib for the treatment of hepatocellular carcinoma with portal vein tumor thrombus.
