lenvatinib and Thrombosis

Background: Transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) may enhance the efficacy of treatment for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT); however, it remains unclear. We aim to evaluate the efficacy of TACE combined with TKIs. Methods: A thorough literature search was performed on major databases since their inception until October 2022. Based on the eligibility criteria, eight studies (2103 patients) were included. Results: Meta-analysis showed that TACE+sorafenib/apatinib had a better tumor response (objective response rate (ORR): RR = 4.85, 95% CI 2.68−8.75, disease control rate (DCR): RR = 3.23, 95% CI 1.88−5.56), and prolonged OS (HR = 0.50, 95%CI 0.42−0.60, p < 0.00001) than TACE alone. TACE+lenvatinib was stronger than TACE+sorafenib in ORR (60.7% vs. 38.9%) and TTP (HR = 0.61, 95% CI 0.43−0.86), whereas it was similar in DCR (96.4% vs. 96.3%) and OS (HR = 0.70 95% CI 0.46−1.05). Conclusions: TACE plus sorafenib or apatinib was superior to TACE alone for hepatocellular carcinoma with PVTT; no significant advantage was found between TACE+lenvatinib and TACE+sorafenib, although TACE+lenvatinib performed better in terms of ORR and TTP.

The efficacy and safety of transarterial chemoembolization (TACE) plus lenvatinib in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) have not been evaluated.. 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.. 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.. 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.. 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.

This study evaluated the efficacy and safety of transarterial chemoembolization (TACE) combined with lenvatinib plus programmed death (PD)-1 inhibitor (TACE-L-P) versus TACE combined with sorafenib plus PD-1 inhibitor (TACE-S-P) in the treatment of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).. The clinical data of patients with HCC and PVTT treated with TACE-L-P or TACE-S-P from January 2018 to March 2022 were collected. The Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and modified RECIST (mRECIST) standard were used to evaluate the therapeutic effect. The progression-free survival (PFS) and overall survival (OS) of the two groups were compared. Blood samples were collected before and after treatment to detect the changes of biochemical indicators, and the adverse events (AEs) related to treatment were recorded.. A total of 165 patients were included in the study, including 80 patients receiving TACE-L-P treatment and 85 patients receiving TACE-S-P. Patients in the TACE-L-P group had longer median OS (21.7 months vs. 15.6 months, P = 0.0027), longer median PFS (6.3 months vs. 3.2 months, P < 0.0001), higher objective response rate (41.25% vs. 30.59%, P = 0.008), and higher disease control rate (86.25% vs. 62.35%, P = 0.008) than those in the TACE-S-P group. Multivariate analysis of the TACE-L-P group showed that VP classification of PVTT, Child-Pugh grade, interleukin-17 (IL-17), vascular endothelial growth factor (VEGF), procalcitonin (PCT), and C-reactive protein (CRP) were independent factors significantly affecting patients' OS (P < 0.05). There was no significant difference in the incidence and severity of AEs between the two groups.. TACE-L-P treatment can improve the survival of patients with HCC and PVTT with an acceptable safety, but higher inflammatory indicators will affect the therapeutic effect.

Although the appearance of portal vein tumor thrombus (PVTT) is significantly associated with unfavorable prognosis, there is insufficient evidence to confirm the efficacy and safety of the triple combination of transarterial chemoembolization (TACE), lenvatinib, and programmed cell death-1 (PD-1) inhibitor for patients with hepatocellular carcinoma (HCC) and PVTT. Furthermore, it remains unclear which patient type can obtain the best survival benefit from this combination therapy.. The data of 160 patients with HCC and PVTT treated with TACE combined with lenvatinib plus PD-1 inhibitor (TACE+LEN + PD-1 group) or TACE combined with lenvatinib (TACE+LEN group) were retrospectively collected and analyzed. To estimate the efficacy and safety of combination therapy for patients with advanced HCC, tumor response, progression-free survival (PFS), overall survival (OS), biochemical indices, and adverse events (AEs) were assessed in this study. More importantly, tumor immune-related cytokines were used to identify biomarkers predicting the therapeutic response of combination therapy.. TACE+LEN + PD-1 was superior to TACE+LEN in OS (23.5 vs. 18.3 months, p = 0.0002) and PFS (7.5 vs. 4.3 months, p < 0.0001). Moreover, TACE+LEN + PD-1 achieved more preferable benefits with respect to disease control rate (80.00% vs. 56.67%) and objective response rate (38.57% vs. 24.45%) compared with TACE+LEN in patients with HCC and PVTT (p = 0.025). Multivariate analysis showed that Child-Pugh grade, PVTT classification, treatment option, and interleukin (IL)-6, IL-17, interferon (IFN)-α, and vascular endothelial growth factor (VEGF) levels were independent factors related to OS, whereas PVTT classification, treatment option, and IL-6 and IFN-α levels were independent factors related to PFS. Furthermore, the subgroup analysis illustrated that the inflammatory cytokines VEGF, IL-6, IL-17, and IFN-α might be novel biomarkers for predicting the survival prognosis of patients with advanced HCC and PVTT treated with TACE+LEN + PD-1. The safety in the combination group was acceptable.. Compared with TACE+LEN, the triple combination treatment of TACE+LEN + PD-1 has more promising clinical outcomes and acceptable safety in patients with HCC and PVTT. Child-Pugh grade, PVTT classification, and IL-6, IL-17, IFN-α, and VEGF levels are independent prognostic factors for survival time.

Transarterial radioembolization (TARE) has shown promising results in treating advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT). However, whether TARE can provide superior or comparable outcomes to tyrosine kinase inhibitor (TKI) in patients with HCC and PVTT remains unclear. We compared the outcomes of TARE and TKI therapy in treatment-naïve patients with locally advanced HCC and segmental or lobar PVTT.. This multicenter study included 216 patients initially treated with TARE (n=124) or TKI (sorafenib or lenvatinib; n=92) between 2011 and 2021. Baseline characteristics were balanced using propensity score matching (PSM) or inverse probability of treatment weighting (IPTW). The primary outcome was overall survival (OS). The secondary outcomes included progression-free survival (PFS) and objective response rate (ORR).. In the unmatched cohort, the median OS of the TARE and TKI groups were 28.2 and 7.2 months, respectively (p<0.001), and the TARE group experienced significantly and independently longer OS compared to the TKI group (adjusted hazard ratio=0.41, 95% confidence interval=0.28-0.60, p<0.001). Similar results were observed in the study cohorts balanced with IPTW (p=0.003) or PSM (p=0.004). Although PFS was comparable between the two groups, the TARE group showed a trend of prolonged PFS in a subpopulation of patients with Vp1 or Vp2 PVTT (p=0.052). In the matched cohorts, the ORR of the TARE group was 53.0-56.7%, whereas that of the TKI group was 12.3-15.0%.. For patients with advanced HCC with segmental or lobar PVTT and well-preserved liver function, TARE may provide superior OS compared to sorafenib or lenvatinib.

Patients with hepatocellular carcinoma (HCC) involving portal vein tumor thrombosis (PVTT) are presently lacking effective treatment options. We aimed to compare the efficacy and safety of lenvatinib with or without SBRT for HCC with PVTT.. This retrospective analysis included 37 patients treated with lenvatinib in combination with SBRT and 77 patients treated with lenvatinib alone from August 2018 to August 2021. Overall survival (OS), progression-free survival (PFS), intrahepatic PFS (IHPFS) and objective remission rate (ORR) were compared between the two groups, while adverse events (AEs) was analyzed between the two groups to assess safety profiles.. Median OS, PFS and IHPFS were significantly prolonged in the combination treatment group compared with the single treatment group (median OS, 19.3 vs. 11.2 months, p < 0.001; median PFS: 10.3 vs. 5.3 months, p < 0.001; median IHPFS, 10.7 vs. 5.3 months, p < 0.001). Moreover, a higher ORR (56.8% vs. 20.8%, P < 0.001) were observed in the lenvatinib combined with SBRT group. In subgroup analyses of Vp1-2 and Vp3-4 group, median OS, PFS and IHPFS were also significantly longer in the lenvatinib combined with SBRT group than those in the lenvatinib alone group. AEs in the combined therapy group were mostly manageable and the incidence was not statistically significant compared to the monotherapy group.. Lenvatinib plus SBRT had a significantly better survival benefit than lenvatinib monotherapy in the treatment of HCC patients with PVTT and was well tolerated.

Hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) predicts a poor prognosis. The aim of the present study was to evaluate the efficacy and safety of using lenvatinib and camrelizumab combined with transarterial chemoembolization (TACE) to treat HCC with PVTT.. This was a single-arm, open-label, multicenter, and prospective study. Eligible patients with advanced HCC accompanied by PVTT were enrolled to receive TACE combined with lenvatinib and camrelizumab. The primary endpoint was progression-free survival (PFS), while the secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety.. Between April 2020 and April 2022, 69 patients were successfully enrolled. With a median follow-up time of 17.3 months, the median age of the patient cohort was 57 years (range: 49-64 years). According to modified Response Evaluation Criteria in Solid Tumors, the ORR was 26.1% (18 partial responses [PRs]) and the DCR was 78.3% (18 PRs, 36 stable diseases [SDs]). The median PFS (mPFS) and median OS (mOS) were 9.3 and 18.2 months, respectively. And tumor number >3 was identified as an adverse risk factor for both PFS and OS. The most common adverse events across all grades included fatigue (50.7%), hypertension (46.4%), and diarrhea (43.5%). Twenty-four patients (34.8%) experienced Grade 3 toxicity that was relieved by dose adjustment and symptomatic treatment. No treatment-related deaths occurred.. TACE combined with lenvatinib and camrelizumab is a well-tolerated modality treatment with promising efficacy for advanced HCC with PVTT.

In this report, we describe a case of highly advanced hepatocellular carcinoma with tumor thrombosis extending into the main portal vein of the pancreas that was successfully treated with adjuvant lenvatinib after right hepatic resection with thrombectomy. A 70-year-old woman was referred from the clinic because of elevated hepatobiliary enzymes. The patient was positive for the hepatitis B virus antigen at our hospital. The tumor markers were highly elevated with alpha-fetoprotein (14.5 U/mL) and protein induced by vitamin K absence (PIVKAII) (1545 ng/mL), suggesting hepatocellular carcinoma. Dynamic abdominal computed tomography showed an early enhanced tumor approximately 6 cm in size and portal vein tumor thrombosis filling the main portal vein, but not extending into the splenic or superior mesenteric vein (SMV). On magnetic resonance imaging 1 week after CT, portal vein tumor thrombosis had extended to the confluence of the splenic vein with the SMV, indicating rapid tumor growth. Thus, we performed emergent right hepatectomy with tumor thrombectomy. Postoperatively, we treated the patient with lenvatinib for a tumor reduction surgery. Fortunately, the patient was alive 2 years postoperatively without recurrence. This case report suggests that a favorable outcome may be achieved with multidisciplinary treatment including resection and postoperative treatment with lenvatinib.

We report a 46-year-old male patient with functional liver damage due to hepatitis B virus infection. A 12 cm hepatocellular carcinoma (HCC) in the left lobe and portal venous tumor thrombosis (PVTT) with vp4 (portal vein tumor thrombosis in the main trunk) were detected by computed tomography (CT). He underwent hepatic arterial infusion chemotherapy (HAIC) with cisplatin 100 mg for HCC and received radiation therapy (39 Gy/13 Fr) for PVTT with vp4. Follow-up CT showed reduction of HCC and reduced PVTT volume after 1 month of treatment. He then initiated lenvatinib therapy at 12 mg/day. One month later, follow-up CT showed no change in HCC size and a reduction in PVTT volume. Two months after initiating lenvatinib, follow-up CT showed no change in HCC, but further reduction in contrast effect and volume of PVTT. Three months after HAIC, he underwent drug-eluting-bead transcatheter arterial chemoembolization (DEB-TACE) with 100 mg of cisplatin (CDDP) for the HCC. After DEB-TACE, he received 12 mg/day with 5-days-on/2-days-off due to vomiting. One month after DEB-TACE, blood evaluation showed decreased tumor markers, and CT revealed that the HCC had grown slightly with no change in PVTT. Five months after HAIC, he underwent DEB-TACE with 100 mg of cisplatin for the HCC. A total of 150 days have passed since the start of lenvatinib treatment, and his Child-Pugh A status has been maintained.

Tyrosine kinase inhibitors (TKIs) are widely used for systemic chemotherapy of hepatocellular carcinoma (HCC). Arterial thromboembolism (ATE) has been reported to be an adverse event associated with TKI therapy, but its incidence is rare. Here, we report a case of an HCC patient who developed a thrombus in the superior mesenteric artery (SMA) while on TKI therapy. The patient was a 78-year-old Japanese man with hepatitis C virus-associated HCC with multiple nodules. Several sessions of transarterial chemoembolization therapy caused him to become refractory to the treatment. Sorafenib and regorafenib therapy had also been previously performed, but his disease continued to progress gradually. Therefore, we started lenvatinib therapy. When a contrast-enhanced computed tomography (CT) examination was performed 2 months later, we found a thrombus in the SMA. Retrospective analysis of the CT images revealed that the thrombus formed during the sorafenib-regorafenib sequential therapy and it developed rapidly, especially during the lenvatinib therapy. An HCC patient developed a thrombus in the SMA during TKI therapy. The incidence of ATE is rare in TKI treatment; however, long-term or sequential TKI therapy may increase the frequency of ATE. Further study is needed.
