Evaluation of percutaneous unilateral trans-femoral implantation of side-hole port-catheter system with coil only fixed-catheter-tip for hepatic arterial infusion chemotherapy

Efficacy and safety of hepatic arterial infusion chemotherapy combined with fruquintinib and tislelizumab for patients with microsatellite stable colorectal cancer liver metastasis following failure of multiple-line therapy

Background and aim

The prognosis of microsatellite stable (MSS)-colorectal cancer liver metastasis (CRCLM) following failure of multi-line therapy remains dismal. The aim of this study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) plus fruquintinib and tislelizumab (HAIC-F-T treatment) for MSS-CRCLM which failed from multiple-line therapy.

Methods

From February 2021 to June 2023, 45 patients with MSS-CRCLM after failure of multiple-line therapy who received HAIC combined with fruquintinib and tislelizumab (HAIC-F-T triple treatment) were enrolled. The combination therapy included HAIC regimens with oxaliplatin and 5-fluorouracil or irinotecan, oxaliplatin, and 5-fluorouracil on days 1-2, intravenous tislelizumab (200 mg) before HAIC on day 1, and oral fruquintinb (3 mg/d) on day 3-21, every 4 weeks. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method.

Results

The follow-up ended on June 22, 2024, with a median follow-up time of 17.5 months. The objective response rate was 42.2%, and the disease control rate was 82.2%. The median OS was 15.3 months (95% confidence interval [CI]:12.634-17.966), and the median PFS was 7.5 months (95% CI:5.318-9.682). The independent risk factors related to worse OS were previous PD-1 immunotherapy (P = 0.021) and the number of HAIC-F-T triple treatment cycles of ≤ 2 (P = 0.007). The incidence of grade 3 or higher adverse events (AEs) was 20%, with the most frequent grade 3 or higher AEs being abdominal pain (3/45, 6.7%).

Conclusion

HAIC combined with fruquintinib and tislelizumab may be an alternative salvage treatment for patients with MSS-CRCLM following failure of multiple-line therapy.

Extrachromosomal circular DNA (eccDNA) characteristics in the bile and plasma of advanced perihilar cholangiocarcinoma patients and the construction of an eccDNA-related gene prognosis model

Extrachromosomal DNAs (eccDNAs) frequently carry amplified oncogenes. This investigation aimed to examine the occurrence and role of eccDNAs in individuals diagnosed with advanced perihilar cholangiocarcinoma (pCCA) who exhibited distinct prognostic outcomes. Five patients with poor survival outcomes and five with better outcomes were selected among patients who received first-line hepatic arterial infusion chemotherapy from June 2021 to June 2022. The extracted eccDNAs were amplified for high-throughput sequencing. Genes associated with the differentially expressed eccDNAs were analyzed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. The differentially expressed bile eccDNA-related genes were used to construct a prognostic model. Across all 10 patients, a total of 19,024 and 3,048 eccDNAs were identified in bile and plasma, respectively. The concentration of eccDNA detected in the bile was 9-fold higher than that in plasma. The chromosome distribution of the eccDNAs were similar between bile and matched plasma. GO and KEGG pathway analyses showed enrichment in the mitogen-activated protein kinase (MAPK) and Wnt/β-catenin pathways in patients with poor survival outcomes. According to the prognostic model constructed by eccDNA-related genes, the high-risk group of cholangiocarcinoma patients displayed significantly shorter overall survival (p < 0.001). Moreover, the degree of infiltration of immunosuppressive cells was higher in patients in the high-risk group. In conclusion, EccDNA could be detected in bile and plasma of pCCA patients, with a higher concentration. A prognostic model based on eccDNA-related genes showed the potential to predict the survival and immune microenvironment of patients with cholangiocarcinoma.

NLCECA score: a serum inflammatory-tumor biomarker score to predict survival of advanced perihilar cholangiocarcinoma after hepatic arterial infusion chemotherapy

Prognostic features in advanced perihilar cholangiocarcinoma (pCCA) patients who received first-line hepatic arterial infusion chemotherapy (HAIC) are unknown. The purpose of our study was to develop an applicable score based on serum inflammatory-tumor biomarkers to predict the survival of advanced pCCA patients who received first-line HAIC. In total, 106 advanced pCCA patients were enrolled as the training cohort. The optimal cutoff values of baseline variables were defined by the receiver operating characteristic method or according to previous publications. According to the results of Cox regression analysis, baseline neutrophil-to-lymphocyte ratio (NLR) > 3.19, carcinoembryonic antigen (CEA) > 10 ng/mL, and carbohydrate antigen 19-9 (CA19-9) > 200 U/mL were identified as independent survival predictors, which were used to develop the NLCECA score (NLR, CEA, and CA19-9). When including the NLCECA score in the multivariate analysis, the NLCECA score was the only independent predictor of survival. The risk of survival decreased by 111.9% for each 1-point increase in the NLCECA score. Additionally, the NLCECA score could also predict survival in another 33 patients in the validation cohort (P < 0.001). In summary, the NLCECA score is a potential biomarker system for predicting the survival of advanced pCCA patients who received first-line HAIC.

Techniques and status of hepatic arterial infusion chemotherapy for primary hepatobiliary cancers

Primary hepatobiliary cancers (PHCs), which mainly include hepatocellular carcinoma (HCC) and biliary tract cancers (BTCs), are mostly diagnosed in the advanced stage and are not candidates for curative surgery or ablation, resulting in a dismal prognosis. Targeted therapies with or without programmed death receptor 1 (PD-1)/PD-L1 inhibitors have been incorporated into first-line treatments for advanced HCC. Systemic chemotherapy is still the mainstay treatment for advanced BTCs, and combining it with PD-1/PD-L1 inhibitors has resulted in prolonged patient survival. Intra-arterial therapies, including trans-arterial chemoembolization, selective internal radiation therapy, and hepatic arterial infusion chemotherapy (HAIC), have been explored and used for advanced hepatobiliary cancers for many years with positive results, particularly when combined with systemic treatments. Recently, an increasing number of phase II/III trials have demonstrated the efficacy and safety of HAIC for the treatment of advanced HCC with portal vein tumor thrombosis and/or a large tumor burden, for the neoadjuvant and adjuvant treatment of HCC with high-risk factors, and for treating advanced intrahepatic and perihilar cholangiocarcinoma. However, the techniques and regimens used for HAIC are diverse and differ greatly between various regions and centers worldwide. This review focuses on these diverse techniques and regimens, as well as the updated evidence on HAIC regarding the treatment of PHCs.

Application of arterial infusion ports in hepatic arterial infusion chemotherapy and embolization for advanced hepatocellular carcinoma

OBJECTIVES

To investigate the safety and feasibility of subcutaneous implantable infusion ports in repeated hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma (HCC) in China.

METHODS

A total of 237 patients who were clinically diagnosed with advanced HCC (CNLC III a/III b) in our hospitals from December 2020 to October 2022 were retrospectively analyzed. The approaches of HAIC were divided into 2 groups: arterial infusion port implantation (group A) and one-time femoral artery catheterization (group B) based on the physicians' suggestion and the patients' intention. The comfort level (evaluated with the General Comfort Questionnaire), complications and average inpatient expenditure were compared between the 2 groups.

RESULTS

116 patients were finally enrolled in the study (group A: 69; group B: 47) and completed HAIC (FOLFOX-4 regimen) according to the dosing schedules (mean: 6±1 cycles). The comfort level of group A was greater than that of group B (p<0.05). The average inpatient expenditure of group A was lower than that of group B (5.4±2.4 vs 10.4±1.9 thousand yuan RMB/cycle, p<0.05). No patients developed port incision infection, hematoma or catheter-related thrombosis in group A, whereas four patients had groin hematomas, one had femoral artery dissection and four had deep vein thrombosis in group B.

CONCLUSION

Hepatic arterial infusion chemotherapy via arterial infusion ports for advanced HCC decreased complications and medical expenditures and improved patient comfort levels compared with indwelling catheters.

Signal enhancement ratio of CE-MRI: a potential biomarker of survival after hepatic arterial infusion chemotherapy in biliary tract cancers

Background

The association of contrast-enhanced MRI (CE-MRI) and the overall survival (OS) of biliary tract cancers (BTC) is ambiguous. Thus, the aim of this study is to evaluate the value of signal enhancement ratio (SER) and its early change in CE-MRI as biomarkers of survival after hepatic arterial infusion chemotherapy (HAIC) in BTC.

Results

One hundred and two BTC patients treated via HAIC with 3cir-OFF regimen between January 2011 and June 2020 were enrolled in this retrospective study. The median progression-free survival (PFS) and OS were 9.8 months [range 1.5–83.3 months, 95% confidence interval (CI) 7.789–11.811] and 14.2 months (range 1.8–83.3 months, 95% CI: 11.106–17.294), respectively. The cutoff value of SER before HAIC (SER0) was 1.04, and both median PFS and OS in the SER0 ≥ 1.04 group were longer than in the SER0 < 1.04 group (median PFS: 10.5 vs. 8.5 months, p = 0.027; median OS: 23.9 vs. 12.3 months, p < 0.001). The median OS in the ΔSER > 0 group was longer than in the ΔSER < 0 group (17.3 versus 12.8 months, p = 0.029 (ΔSER means the change of SER after two cycles of HAIC). Multivariate analysis showed SER0 (p = 0.029) and HAIC treatment cycle (p = 0.002) were independent predictors of longer survival.

Conclusions

SER in CE-MRI before HAIC (SER0) is a potential biomarker for the prediction of survival after HAIC in advanced BTC.

Revisiting Hepatic Artery Infusion Chemotherapy in the Treatment of Advanced Hepatocellular Carcinoma

Hepatic artery infusion chemotherapy (HAIC) is a well-established and common treatment for advanced hepatocellular carcinoma (HCC), particularly in East Asia. However, HAIC is not recognized internationally. Although several trials have demonstrated the safety and efficacy of HAIC, evidence corroborating its overall survival (OS) benefits compared with standard treatments is insufficient. Nevertheless, HAIC may provide prominent benefits in selected patients such as patients with portal vein thrombosis or high intrahepatic tumor burden. Moreover, HAIC has been combined with several therapeutic agents and modalities, including interferon-alpha, multikinase inhibitors, radiation therapy, and immunotherapy, to augment its treatment efficacy. Most of these combinations appeared to increase overall response rates compared with HAIC alone, but results regarding OS are inconclusive. Two prospective randomized controlled trials comparing HAIC plus sorafenib with sorafenib alone have reported conflicting results, necessitating further research. As immunotherapy-based combinations became the mainstream treatments for advanced HCC, HAIC plus immunotherapy-based treatments also showed encouraging preliminary results. The trials of HAIC were heterogeneous in terms of patient selection, chemotherapy regimens and doses, HAIC combination agent selections, and HAIC technical protocols. These heterogeneities may contribute to differences in treatment efficacy, thus increasing the difficulty of interpreting trial results. We propose that future trials of HAIC standardize these key factors to reveal the clinical value of HAIC-based treatments for HCC.

Retrograde embolization technique of the right gastric artery during the implantation of port-catheter system for hepatic arterial infusion chemotherapy

Objective

This study aimed to introduce and evaluate a new embolization technique for the right gastric artery (RGA) during percutaneous implantation of a port-catheter system for hepatic arterial infusion chemotherapy (HAIC).

Methods

From January 2013 to January 2017, 159 patients with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system. In 86 of these patients (56 men; aged 28–88 years; mean: 60.6 ​± ​12.0 years), in whom the RGA was obvious on arteriography, embolization of RGA was attempted using microcoils to protect the gastric mucosa during HAIC. In the first phase (first three years), antegrade embolization of the RGA using a 2.7 Fr microcatheter was performed in 55 patients. In the second phase (next two years), embolization of the RGA was attempted by combining antegrade embolization and retrograde embolization through the left gastric artery (LGA) in 31 patients. The success rates and the incidence of acute gastroduodenal mucosal toxicity (AGMT) in these two groups were compared.

Results

The total success rate of the RGA embolization was 70.9%. The success rate was 83.9% in 31 patients who underwent combined antegrade and retrograde embolization, which was significantly higher than that of antegrade embolization alone (63.6%) performed in 55 patients (p ​= ​0.047). No complications related to embolization of RGA were documented. The incidence of AGMT was 29.1% (16/55) in patients in the first phase, which was significantly higher than that in the patients in the second phase (9.7%, 3/31) (p ​= ​0.037).

Conclusion

A combination of retrograde embolization via LGA could increase the success rates of RGA embolization and reduce the incidence of AGMT after HAIC.

Hepatic Arterial Infusion Chemotherapy with Oxaliplatin and 5-Fluorouracil for Advanced Gallbladder Cancer

PURPOSE

The aim of this study was to assess the safety and efficacy of hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin and 5-fluorouracil for patients with advanced gallbladder cancer (GBC).

MATERIALS AND METHODS

Twenty-six patients with advanced GBC, who underwent HAIC with oxaliplatin and 5-fluorouracil from January 2012 to July 2019, were enrolled in this retrospective study. The HAIC regimen consisted of infusions of oxaliplatin at 40 mg/m² for 2 h, followed by 5-fluorouracil at 800 mg/m² for 22 h on days 1-3 every 3-4 weeks. A maximum of six cycles of HAIC were applied for tumor control patients followed by maintenance with oral capecitabine or S-1. Overall survival (OS), progression-free survival (PFS), tumor response, and adverse events were investigated.

RESULTS

Six of the 26 patients (23.1%) had failed systemic chemotherapy, 8/26 (30.8%) patients had failed various local therapies, and 9/26 (34.6%) patients had contraindications to systemic chemotherapy. The median OS was 13.5 months, and the median PFS was 10.0 months. The overall response rate was 69.2% (18/26), and disease control rate was 92.3% (24/26). Carcinoembryonic antigen (CEA) ≥ 10 U/ml (p = 0.003) and carbohydrate antigen 19-9 (CA19-9) ≥ 200 U/ml (p = 0.000) were independent risk factors for decreased survival. The most frequent Grade 3 or 4 treatment-related adverse event was liver dysfunction (4, 15.4%).

CONCLUSION

HAIC with oxaliplatin and 5-fluorouracil is an acceptable and well-tolerated treatment for advanced gallbladder cancer even for patients in whom systemic chemotherapy had failed or is contraindicated.

LEVEL OF EVIDENCE

Level 2, Observation Study with Dramatic Effect.

Hepatic Arterial Infusion Chemotherapy Using Oxaliplatin Plus 5-Fluorouracil Versus Transarterial Chemoembolization/Embolization for the Treatment of Advanced Hepatocellular Carcinoma with Major Portal Vein Tumor Thrombosis

PURPOSE

To compare the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) to transarterial chemoembolization/embolization (TACE/TAE) for the treatment of advanced hepatocellular carcinoma (HCC) with major portal vein tumor thrombosis (PVTT).

MATERIALS AND METHODS

Forty-six patients with advanced HCC with major PVTT who underwent HAIC or TACE/TAE between April 2013 and April 2017 were included. In the HAIC group (n = 22), oxaliplatin (35-40 mg/m² for 2 h) and 5-fluorouracil (600-800 mg/m² for 22 h) on days 1-3 every 4 weeks were administered for a maximum of six serial courses. In the TACE/TAE group (n = 24), an emulsion of epirubicin (40-60 mg) and lipiodol was administered followed by particles (cTACE), or particles alone embolization (TAE). Overall survival (OS), tumor response according to mRECIST, progression-free survival (PFS), and adverse events were investigated.

RESULTS

Median OS was 20.8 months in the HAIC group versus 4.0 months in the TACE/TAE group (P < 0.001; hazard ratio [HR], 0.17). The HAIC group showed higher tumor response rates than the TACE/TAE group (59.1% [13/22] vs. 22.7% [5/22]; P = 0.014) and a longer median PFS (9.6 vs. 1.5 months; P < 0.001; HR, 0.09). The Child-Pugh class (P = 0.007) and treatment method (P = 0.002) were independent risk factors of survival. The most frequent grade 3 or worse treatment-related adverse events were liver dysfunction (2 [9.1%] vs. 5 [20.8%]), hematological abnormalities (1 [4.5%] vs. 2 [8.3%]), and fever (1 [4.5%] vs. 4 [16.7%]). One treatment-related death due to acute liver failure occurred 3 days after TACE treatment.

CONCLUSION

HAIC may significantly improve OS and provide better tumor control with mild side effects and preserved liver function in patients with advanced HCC with major PVTT compared to TACE/TAE treatment.
