WITHDRAWN: A Case Series of Liver Abscess Formation after Transcatheter Arterial Chemoembolization for Hepatic Tumors

Background and AimAlthough the treatment effect and availability of therapeutic options for advanced hepatocellular carcinoma (HCC) are limited, the downstaging strategy may improve patient prognosis. This study aimed to investigate the potential of combination therapy as a downstaging strategy for treating advanced HCC with portal vein tumor thrombus (PVTT).MethodsThis retrospective case series included patients having advanced HCC with PVTT, who received the combination therapy of sorafenib, camrelizumab, transcatheter arterial chemoembolization (TACE), and stereotactic body radiation therapy (SBRT) from January 2019 to December 2019 in Xiangya Hospital, Central South University. The downstaging rate, treatment responses, progression-free survival (PFS), overall survival (OS), disease control rate, and toxicities were evaluated.ResultsOf the 13 patients, HCC downstaging was achieved in 4 (33.3%) patients who later received hepatectomy. The overall response rate was 41.7%, and the disease control rate was 50.0%. The median PFS time was 15.7 months, with a 1-year PFS rate of 58.3%, whereas the median OS was not reached after 1 year (1-year OS, 83.3%). No severe adverse events or grade 3–4 adverse effect was observed in 12 of the 13 enrolled patients; therapy had to be discontinued in only one patient due to adverse events, who was excluded from the study. The most common adverse effect was fever (n = 4, 33.3%), followed by skin reaction (n = 3, 25%).ConclusionA combination therapy comprising sorafenib, camrelizumab, TACE, and SBRT is an effective downstaging strategy for advanced HCC with PVTT and is associated with few adverse events.

Objective: To investigate the incidence and risk factors for liver abscess formation after treatment with drug-eluting bead chemoembolization (DEB-TACE) in patients with metastatic hepatic tumors (MHT). Methods: The current study is a retrospective analysis of the clinical data of 137 patients with metastatic hepatic tumors who received DEB-TACE treatment in our institute between June 2015 and September 2020. Patients were evaluated for the presence or absence of post-DEB-TACE liver abscess. Univariate and multivariate analyses were used to identify risk factors for liver abscess formation. Results: The incidence of liver abscess formation after the DEB-TACE procedure was 8.76% per patient and 5.53% per procedure. Univariate analysis showed that larger maximum tumor diameter (p = 0.004), Grade one artery occlusion (p < 0.001) and systemic chemotherapy within 3 months before the DEB-TACE procedure (p < 0.001) were all associated with liver abscess formation. However, only systemic chemotherapy within 3 months before the DEB-TACE procedure (OR 5.49; 95% CI 0.34–13.54; p < 0.001) was identified by multivariate analysis to be an independent risk factor. Conclusions: Tumor size, Grade one artery occlusion and recent systemic chemotherapy may all be associated with increased risk of liver abscess formation following DEB-TACE treatment in patients with metastatic hepatic tumors. Advances in knowledge: Identification of risk factors for liver abscess formation following DEB-TACE in patients with MHT. These findings suggest the need for caution and consideration of the aforementioned risk factors on the part of interventional radiologists when designing DEB-TACE strategies and performing post-procedure patient management.
