RESUMO
BACKGROUND: Hepatocellular carcinoma (HCC) patients complicated with portal vein tumor thrombus (PVTT) exhibit poor prognoses and treatment responses. AIM: To investigate efficacies and safety of the combination of PD-1 inhibitor, transcatheter arterial chemoembolization (TACE) and Lenvatinib in HCC subjects comorbid with PVTT. METHODS: From January 2019 to December 2020, HCC patients with PVTT types I-IV were retrospectively enrolled at Beijing Ditan Hospital. They were distributed to either the PTL or TACE/Lenvatinib (TL) group. The median progression-free survival (mPFS) was set as the primary endpoint, while parameters like median overall survival, objective response rate, disease control rate (DCR), and toxicity level served as secondary endpoints. RESULTS: Forty-one eligible patients were finally recruited for this study and divided into the PTL (n = 18) and TL (n = 23) groups. For a median follow-up of 21.8 months, the DCRs were 88.9% and 60.9% in the PTL and TL groups (P = 0.046), res-pectively. Moreover, mPFS indicated significant improvement (HR = 0.25; P < 0.001) in PTL-treated patients (5.4 months) compared to TL-treated (2.7 months) patients. There were no treatment-related deaths or differences in adverse events in either group. CONCLUSION: A triplet regimen of PTL was safe and well-tolerated as well as exhibited favorable efficacy over the TL regimen for advanced-stage HCC patients with PVTT types I-IV.

BACKGROUND: Recently, combination therapy has shown a better trend towards improved tumour response and survival outcomes than monotherapy in patients with hepatocellular carcinoma (HCC). However, research on triple therapy [lenvatinib + sintilimab + transarterial chemoembolization (TACE)] as a first-line treatment for advanced HCC is limited. AIM: To evaluate the safety and efficacy of triple therapy as a first-line treatment for advanced HCC. METHODS: HCC patients with Barcelona Clinic Liver Cancer stage C treated with triple therapy were enrolled. All patients were treated with lenvatinib every day and sintilimab once every 3 wk. Moreover, TACE was performed every 4-6 wk if necessary. The primary outcome of the study was overall survival (OS). The secondary outcomes were the objective response rate (ORR), disease control rate (DCR), and incidence of adverse events. RESULTS: Forty HCC patients who underwent triple therapy were retrospectively analysed from January 2019 to January 2022. With a median follow-up of 8.5 months, the 3-, 6-, and 12-mo OS rates were 100%, 88.5%, and 22.5%, respectively. The ORR and DCR were 45% and 90%, respectively. The median progressive free survival and median OS were not reached. Common complications were observed in 76% of the patients (grade 3, 15%; grade 4, 2.5%). CONCLUSION: Combination therapy comprising lenvatinib, sintilimab and TACE achieved promising outcomes in advanced HCC patients and had manageable effects.
RESUMO
BACKGROUND: The combination therapy of transarterial chemoembolization and radiofrequency ablation (TACE-RFA) shows promising efficacy in large hepatocellular carcinoma (HCC). Data on the clinical efficacy and safety of TACE-RFA for large HCC with barcelona clinic liver cancer (BCLC) stage C are lacking in China. AIM: To determine the safety and efficacy of TACE-RFA for large, advanced HCC. METHODS: Patients of HCC with BCLC stage C who were treated with TACE-RFA or TACE alone at our institute from August 2008 to January 2017 were retrospectively reviewed. The complications were observed. The associations between overall survival (OS) and treatment method were analysed. RESULTS: Data were collected from 102 HCC patients. Among them, 64 underwent TACE-RFA and 38 underwent TACE. The combination of TACE and RFA was safe. All complications were controllable. The median OS in the TACE-RFA group was significantly longer than that in the TACE group (8.0 mo vs 4.0 mo, P = 0.000). The 6-, 12- and 24-mo survival rates of the combination group were 68.8%, 34.4%, and 10.9%, respectively, while those of the TACE group were 36.8%, 7.9%, and 0% (P < 0.05). CONCLUSION: TACE-RFA has an advantage over TACE alone in improving OS in large HCC patients with BCLC stage C.
RESUMO
To retrospectively compare the clinical efficacy and safety of CT-guided percutaneous injection of lobaplatin vs. ethanol for chemical ablation combined with radiofrequency ablation (RFA) in patients with hepatocellular carcinomas (HCCs) in high-risk locations. From January 2017 to June 2018, a total of 41 patients with HCCs in high-risk locations were enrolled and divided into two groups: percutaneous lobaplatin injection (PLI+RFA) group and percutaneous ethanol injection (PEI+RFA) group. The mixture of lobaplatin or ethanol was accurately injected into the high-risk part of the tumors, while RFA ablated the non-high-risk part. The efficacy and safety were compared between the two groups. 41 patients had 51 lesions in high-risk locations, including 24 cases with 30 lesions in PLI+RFA group and 17 cases with 21 lesions in PEI+RFA group. The complete ablation rate was 93.3% (28/30) in PLI+RFA group and 90.5% (19/21) in PEI+RFA group (P=1.000). The 2-year local tumor progression rate of PLI+RFA group and PEI+RFA group was 20.0% (6/30) and 19.0% (4/21), respectively (P=1.000). No significant differences were found in time to progression and overall survival between the two groups (P=0.501 and P=0.424, respectively). The incidence and severity of adverse events between the two groups were similar (P > 0.05). No severe complications were observed in both groups. Percutaneous lobaplatin injection combined with RFA in the treatment of HCC in high-risk locations may achieve the complete ablation rate similar to percutaneous ethanol injection combined with RFA, but further research is needed to confirm.
