Percutaneous thermal ablation combined with TACE versus TACE monotherapy in the treatment for liver cancer with hepatic vein tumor thrombus: A retrospective study.

ABSTRACT:

Purpose

To investigate the efficacy of percutaneous thermal ablation combined with transarterial chemoembolization (TACE) versus TACE monotherapy in treating primary liver cancer with hepatic vein tumor thrombus (HVTT), and to identify potential factors of overall survival after combination therapy.

Materials and methods

Patients with primary liver cancer and HVTT from 2011 to 2016 at our institute were retrospectively identified. They were divided into two groups (group A and group B). Patients in group A underwent TACE with subsequent percutaneous thermal ablation, while patients in group B who were unsuitable for ablation received TACE monotherapy. Characteristics and survival data of the two groups were analyzed and compared. Relevant factors for overall survival (OS) of group A were explored by univariate analysis.

Results

Twenty-six patients were included and analyzed. The median OS for group A (n = 13) was 18 months, while the 1-, 2- and 3-year survival rates were 58.6%, 46.9% and 46.9%, respectively. The median OS for group B (n = 13) was 6.5 months and the 1-year survival rate was 10.9%. The survival of group A was significantly better than group B (P = 0.02). The following factors were related with overall survival of group A: ablation technique, complete response of tumor and HVTT, Child-pugh grade, pre-operative extrahepatic metastases and lymph node metastases. In group A, patients who achieved complete response had the longest average survival time (42.1 months).

Conclusion

For patients with primary liver cancer and HVTT, percutaneous thermal ablation and TACE present better efficacy than TACE monotherapy. Long-term survival could be achieved in selected patients.

Project description:BackgroundThe objective of this study is to examine factors associated with thrombus extension after early experience with mechanochemical ablation, which combines mechanical damage to the venous endothelium with infusion of a sclerosant.MethodsA retrospective review was performed of patients who underwent mechanochemical ablation to treat saphenous vein insufficiency in the thigh including the saphenofemoral junction. Data abstracted included patient demographics, procedural details, and postprocedural outcomes. Thrombus extension was determined by postprocedural duplex ultrasound and classified as flush closure with the femoral vein and any extension of thrombus into the femoral vein.ResultsSeventy-three patients met inclusion criteria. The mean age of the population was 60, 17.8% were female, and the mean body mass index (BMI) was 30.7. Seven (9.6%) patients who underwent mechanochemical ablation experienced saphenous vein closure flush with the femoral vein. Eleven (15%) patients experience extension of thrombus to less than 50% of the diameter of the femoral vein and one patient experienced complete thrombosis of the femoral vein. There was no significant difference in age, sex, or comprehensive classification system for chronic venous disorders between the group with thrombus extension and the group without, with the exception of BMI. The mean BMI in the group with thrombus extension was 26.8 vs. 32 in the group without (P = 0.02). There was no significant difference between the 2 groups in sclerosant volume used, distance between catheter tip and SFJ, and mean diameter of GSV in the thigh.ConclusionsIn this cohort, the incidence of thrombus extension into the femoral vein with mechanochemical ablation was high relative to rates of thrombus extension associated with reported rates of thermal ablation. Further investigation with larger cohorts, and standardized reporting is required to characterize the true rate of thrombus extension after mechanochemical ablation and identify maneuvers which may prevent thrombus extension.

Project description:PurposeWe report a 10-year experience in cancer therapy with concomitant treatment of percutaneous thermal ablation (PTA) and immune checkpoint blockers (ICBs).Material and methodsThis retrospective cohort study included all patients at a single tertiary cancer center who had received ICBs at most 90 days before, or 30 days after, PTA. Feasibility and safety were assessed as the primary outcomes. The procedure-related complications and immune-related adverse events (irAEs) were categorized according to the Common Terminology Criteria for Adverse Events v5.0 (CTCAE). Efficacy was evaluated based on overall survival (OS), progression-free survival (PFS), and local progression-free survival (LPFS) according to the indication, ablation modality, neoplasm histology, and ICB type.ResultsBetween 2010 and 2021, 78 patients (57% male; median age: 61 years) were included. The PTA modality was predominantly cryoablation (CA) (61%), followed by radiofrequency ablation (RFA) (31%). PTA indications were the treatment of oligo-persistence (29%), oligo-progression (14%), and palliation of symptomatic lesions or prevention of skeletal-related events (SREs) (56%). Most patients received anti-PD1 ICB monotherapy with pembrolizumab (n = 35) or nivolumab (n = 24). The feasibility was excellent, with all combined treatment performed and completed as planned. Ten patients (13%) experienced procedure-related complications (90% grade 1-2), and 34 patients (44%) experienced an irAE (86% grade 1-2). The only factor statistically associated with better OS and PFS was the ablation indication, favoring oligo-persistence (p = 0.02). Tumor response was suggestive of an abscopal effect in four patients (5%).ConclusionsThe concomitant treatment of PTA and ICBs within 2-4 weeks is feasible and safe for both palliative and local control indications. Overall, PTA outcomes were found to be similar to standards for patients not on ICB therapy. While a consistently reproducible abscopal effect remains elusive, the safety profile of concomitant therapy provides the framework for continued assessment as ICB therapies evolve.
