Are histomorphological patterns a predictor for survival in uveal melanoma patients with hepatic metastases undergoing hepatic artery infusion chemotherapy?

In uveal melanoma (UM) patients with hepatic metastases, hepatic artery infusion chemotherapy (HAIC) is a viable, palliative treatment option. To evaluate the impact of two histomorphological patterns (spindle cell vs. epithelioid) of liver metastases on median overall survival (mOS) in UM patients undergoing HAIC. A retrospective analysis with 60 UM patients (29 females, mean age: 61.6 ± 12.1 years) with hepatic metastases was performed. Histomorphological patterns in metastases were analysed and classified as either predominant spindle cell or epithelioid pattern. mOS between both patient groups was analysed using Kaplan-Meier curves and the log-rank test. In 73.3% (44/60) of the metastases, a predominant epithelioid pattern, in 21.7% (13/60) a predominant spindle cell pattern, and in 5% (3/60) other patterns were found. No significant differences between patients with an epithelioid (mOS: 14.2 months, 95% CI: 8.8-19.6) and a spindle cell pattern (mOS: 14.4 months, 95% CI: 4.3-24.5) were detected by the log-rank test, χ2(2) = 0.22, P = 0.881. Histomorphological patterns of UM metastases do not seem to be a predictor for mOS in UM patients undergoing HAIC.

Radiation-Emitting metallic stent for unresectable bismuth type III or IV perihilar cholangiocarcinoma: a multicenter randomized trial

Background & Aims: Self-expandable metallic stents (SEMSs) have been recommended for patients with unresectable malignant biliary obstruction while radiation-emitting metallic stents (REMSs) loaded with 125I seeds have recently been approved to provide longer patency and overall survival in malignant biliary tract obstruction. This trial is to evaluate the efficacy and safety of REMS plus hepatic arterial infusion chemotherapy (REMS-HAIC) versus SEMS plus HAIC (SEMS-HAIC) for unresectable perihilar cholangiocarcinoma (pCCA). Methods: This multicenter randomized controlled trial recruited patients with unresectable Bismuth type III or IV pCCA between March 2021 and January 2023. Patients were randomly assigned (1:1 ratio) to receive either REMS-HAIC or SEMS-HAIC using permuted block randomization, with a block size of six. The primary endpoint was overall survival (OS). The secondary endpoints were time to symptomatic progression (TTSP), stent patency, relief of jaundice, quality of life, and safety. Results: A total of 126 patients were included in the intent-to-treat population, with 63 in each group. The median OS was 10.2 months versus 6.7 months (P=0.002). The median TTSP was 8.6 months versus 5.4 months (P=0.003). The median stent patency was longer in the REMS-HAIC group than in the SEMS-HAIC group (P=0.001). The REMS-HAIC group showed better improvement in physical functioning scale (P<0.05) and fatigue symptoms (P<0.05) when compared to the SEMS-HAIC group. No significant differences were observed in relief of jaundice (85.7% vs. 84.1%; P=0.803) or the incidence of grade 3 or 4 adverse events (9.8% vs. 11.9%; P=0.721). Conclusion: REMS plus HAIC showed better OS, TTSP, and stent patency compared with SEMS plus HAIC in patients with unresectable Bismuth type III or IV pCCA with an acceptable safety profile.

Amylase intrapancreatic infusion delays insulin release during an intravenous glucose tolerance test, proof of acini-islet-acinar interactions.

The possible existence of an acini-islet-acinar (AIA) reflex, involving mutual amylase and insulin interactions, was investigated in the current acute experiment on pigs. To confirm the existence of an AIA reflex and justify the placement of the exocrine and endocrine pancreatic components within the same organ. The study was performed on six pigs under general anesthesia. An intravenous glucose tolerance test was performed, with a bolus infusion of 50% glucose to the jugular vein, while amylase (5000 U/kg) or vehicle intrapancreatic infusions were administered via the pancreaticoduodenalis cranialis artery during 30 min with a 1 mL/min flow rate. The amylase infusion to pancreatic arterial circulation inhibited and delayed the insulin release peak which is usually associated with the highest value of blood glucose and is typically observed at 15 min after glucose infusion, for > 1 h. The intrapancreatic infusion of the vehicle (saline) did not have any effect on the time frame of insulin release. Infusion of 1% bovine serum albumin changed the insulin release curve dramatically and prolonged the high range of insulin secretion, far beyond the glucose peak. Intrapancreatic arterial infusion of amylase interrupted the integrated glucose-insulin interactions. This confirms an AIA reflex and justifies placement of the exocrine and endocrine pancreatic components within the same organ.

Efficacy and safety of transcatheter arterial chemoembolization followed by hepatic arterial infusion chemotherapy combined with TKI and PD-1 inhibitors as first-line treatment for advanced hepatocellular carcinoma

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) followed by hepatic arterial infusion chemotherapy (HAIC) combined with TKI drugs and PD-1 inhibitors as the first-line treatment for advanced hepatocellular carcinoma (HCC). We retrospectively analyzed the data of 70 patients with advanced HCC treated in the Department of Oncology of Guangdong Provincial Hospital of Integrated Traditional Chinese and Western Medicine between July, 2020 and June, 2023. 23 of the patients received TACE combined with HAIC and TKI (TACE+HAIC+ TKI group) and 47 received TACE combined with HAIC, PD-1 inhibitors and TKI (TACE+HAIC+PD-1+TKI group). The clinical characteristics, laboratory test results, efficacy, outcomes and adverse events of the patients were compared between the two groups. The TACE+HAIC+TKI and TACE+HAIC+PD-1+TKI groups had significantly different objective remission rates (ORR; 60.87% vs 36.17%, P=0.031), comparable disease control rates (95.65% vs 93.62%, P=0.068), and different median progression-free survival (PFS) time (10.2 vs 11.8 months, P=0.003) and median overall survival (OS) time (15.7 vs 19.5 months, P=0.035). After propensity score matching (PSM), the median PFS and OS time of the two groups was 10.1 vs 14.5 months (P= 0.024) and 14.2 vs 21.2 months (P=0.221), respectively. The 1-year PFS rates of the 2 groups were 24.0% vs 52.2%, and the 1-, 2-and 3-year OS rates were 72.3% vs 93.1%, 23.9% vs 63.8%, and 23.9% vs 36.5%, respectively. The incidence of proteinuria was significantly higher in TACE+HAIC+PD-1+TKI group than in TACE+HAIC+TKI group (21.28% vs 0, P=0.025), but the incidences of grade 3-4 treatment-related adverse events were all similar between the two groups. The first-line treatment with TACE+HAIC+PD-1+TKI is safe and effective for advanced HCC and can significantly prolong the survival of the patients.

Sequential vs. concurrent systemic therapies in combination with FOLFOX-HAIC for locally advanced hepatocellular carcinoma: a single-center, real-world cohort study

BackgroundTri-combination therapy based on hepatic arterial infusion chemotherapy (HAIC) of infusion fluorouracil, leucovorin, and oxaliplatin (FOLFOX-HAIC) plus immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) for the locally advanced hepatocellular carcinoma (HCC) patients have been proven effective. However, whether it was best for these HCC patients to start with the most potent therapeutic pattern was still under debate. This retrospective study evaluated the efficacy and safety of FOLFOX-HAIC combined with systemic therapies in the patterns of sequential and concurrent schedules.MethodsThis real-world study included 117 unresectable HCC patients who initially received either FOLFOX-HAIC monotherapy (HAIC group, n = 44) or concurrent ICIs and TKIs (ConHAIC group, n = 73) from March 2020 and June 2022, during the period of FOLFOX-HAIC monotherapy in HAIC group, patients in the HAIC group (n = 30) experienced progressive disease (PD) would have their treatment pattern converted from the FOLFOX-HAIC monotherapy to the combination of FOLFOX-HAIC plus ICIs and TKIs sequentially (SeqHAIC group). The progression-free survival (PFS) and overall survival (OS), as primary outcomes, were compared between patients in the SeqHAIC and ConHAIC groups.ResultsThe median follow-up time of the SeqHAIC group was 24.92 months (95% CI, 12.74–37.09 months) and of the ConHAIC group was 17.87 months (95% CI, 16.85–18.89 months) and no significant difference was observed in both PFS (HR, 1.572; 95% CI, 0.848–2.916; p = 0.151) and OS (HR, 1.212; 95% CI, 0.574–2.561; p = 0.614) between the SeqHAIC and the ConHAIC groups. As for the tumor responses, there was no significant difference between the two groups regarding tumor responses, overall response rates (p = 0.658) and disease control rates (p = 0.641) were 50.0%, 45.2%, and 83.3%, 89.0% for the SeqHAIC and the ConHAIC groups, respectively.ConclusionOur study revealed that sequential systemic ICIs and TKIs in combination with FOLFOX-HAIC provides similar long-term prognosis and better tolerability compared to concurrent therapy for locally advanced HCC patients. Prospective studies with a larger sample size and longer follow-up are required to validate these findings.

Oxaliplatin-induced peripheral neuropathy with hepatic arterial versus intravenous infusion in metastatic colorectal cancer.

Oxaliplatin, a major drug in metastatic colorectal cancer (mCRC), is responsible for cumulative, dose-limiting peripheral neuropathy (PN). Whether the hepatic arterial infusion (HAI) route can limit oxaliplatin-induced PN in comparison with the intravenous (IV) route has not been specifically explored so far. We compared the frequency and severity of PN in oxaliplatin-naive patients with mCRC included in trials that evaluated treatment with oxaliplatin administered either by HAI (ACCORD 04, CHOICE, OSCAR, and PACHA-01 trials) or by IV route (FFCD 2000-05 trial). We retrieved anonymized, prospectively collected data from trial databases for the ACCORD 04, CHOICE, and FFCD 2000-05 trials and through a review of Gustave Roussy patients' electronic medical records for PACHA-01 and OSCAR trials. The primary endpoint was the incidence of clinically significant PN (grades 2 to 4) according to the cumulative dose of oxaliplatin received. Secondary endpoints were time to onset of neuropathy as a function of the cumulative dose of oxaliplatin, discontinuation of oxaliplatin for neurotoxicity, and safety. A total of 363 patients were included (IV, 300; HAI, 63). In total, 180 patients in the IV group (60%) and 30 patients in the HAI group (48%) developed clinically significant PN, with no significant difference between the two groups (p = 0.23). No difference was shown in the time to onset of PN either (p = 0.23). The administration of oxaliplatin HAI rather than IV in the treatment of mCRC does not reduce the incidence, precocity, and severity of PN.

Clinical Effects and Safety of Intra-Arterial Infusion Chemotherapy with Lipiodol versus Intra-Arterial Infusion Chemotherapy Alone for Treatment of Advanced Hepatocellular Carcinoma

Introduction: This study aimed to assess the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) in 2 groups of patients: those who receive lipiodol (referred to as the lipiodol group) and those who do not receive lipiodol (referred to as the control group). Methods: From January 2016 through December 2023, 85 patients with advanced hepatocellular carcinoma were enrolled in this retrospective study. In total, 40 patients received HAIC with lipiodol, while 45 patients were given HAIC without lipiodol. The modified response evaluation criteria for solid tumors were used to evaluate the tumor response, which was assessed through an imaging study. The two groups were compared regarding their overall survival (OS), progression-free survival (PFS), and safety. Results: The outcomes between the lipiodol group and control group demonstrated no significant difference: the objective response rates (p = 0.066) were 32.5% and 15.6%; the disease control rates (p = 0.556) were 67.5% and 73.3%; the median OS times (p = 0.339) were 224 days and 398 days; the median PFS (p = 0.334) times were 191 days and 286 days in the lipiodol group and the control group, respectively. Adverse events also showed no significant difference between the two groups: elevation of total bilirubin (p = 0.834) rates were 40.0% and 37.8%; elevation of alanine aminotransferase (p = 0.191) percentages were 35.0% and 22.2%; and elevation of aspartate aminotransferase values (p = 0.058) were 65.0% and 44.4% in the lipiodol group and the control group, respectively. Conclusions: HAIC without lipiodol was non-inferior to HAIC with lipiodol in the clinical outcome.

Survival Benefit of Lenvatinib Plus PD-1 Inhibitor with or Without HAIC in Advanced Hepatocellular Carcinoma Beyond Oligometastasis: a Multicenter Cohort Study.

The outcome between Lenvatinib plus programmed cell death protein-1 (PD-1) inhibitor and Lenvatinib in HCC beyond oligometastasis was unclear. In this multicenter, we compared the prognosis of Lenvatinib plus PD-1 inhibitor with Lenvatinib in HCC beyond oligometastasis. A total of 296 patients from six institutions were included. The patients were divided into two groups: (a) concurrent Lenvatinib plus PD-1 inhibitor treatment (Len+PD-1 group) and (b) Lenvatinib monotherapy (Len group). The primary endpoint was overall survival (OS), the second endpoint was progression-free survival (PFS) and efficacy. The median OS was 20.1 ± 1.2 (17.7-22.5) months and 15.7 ± 1.5 (12.8-18.6) months in the Len+PD-1 and Len groups, respectively. The 12-, 24-, and 36-month OS rates were 79.1%, 39.4%, and 10.7% in the Len+PD-1 group, and 76.3%, 29.7%, and 0% in the Len group, respectively. The OS and PFS rates of the Len+PD-1 group were significantly longer compared with the Len group (hazard ratio [HR], 0.88; 95% confidence index [CI], 0.49-0.94; P = 0.021) and (HR, 0.66; 95% CI, 0.50-0.87; P = 0.003). A subgroup analysis revealed that OS (HR, 0.57; 95% CI, 0.36-0.90; P = 0.016) was improved between the Len+PD-1 and Len groups with hepatic artery infusion chemotherapy (HAIC) treatment, whereas OS (HR, 1.11; 95% CI, 0.68-1.80; P = 0.689) was similar between the Len and Len+PD-1 groups without HAIC. Lenvatinib combined with PD-1 inhibitor significantly improves the survival of HCC beyond oligometastasis. For patients with HAIC, there was obviously significance between Len and Len+PD-1 groups.

A deep learning model for personalized intra-arterial therapy planning in unresectable hepatocellular carcinoma: a multicenter retrospective study

Unresectable Hepatocellular Carcinoma (uHCC) poses a substantial global health challenge, demanding innovative prognostic and therapeutic planning tools for improved patient management. The predominant treatment strategies include Transarterial chemoembolization (TACE) and hepatic arterial infusion chemotherapy (HAIC). Between January 2014 and November 2021, a total of 1725 uHCC patients [mean age, 52.8±11.5 years; 1529 males] received preoperative CECT scans and were eligible for TACE or HAIC. Patients were assigned to one of the four cohorts according to their treatment, four transformer models (SELECTION) were trained and validated on each cohort; AUC was used to determine the prognostic performance of the trained models. Patients were stratified into high and low-risk groups based on the survival scores computed by SELECTION. The proposed AI-based treatment decision model (ATOM) utilizes survival scores to further inform final therapeutic recommendation. In this study, the training and validation sets included 1448 patients, with an additional 277 patients allocated to the external validation sets. The SELECTION model outperformed both clinical models and the ResNet approach in terms of AUC. Specifically, SELECTION-TACE and SELECTION-HAIC achieved AUCs of 0.761 (95% CI, 0.693-0.820) and 0.805 (95% CI, 0.707-0.881) respectively, in predicting ORR in their external validation cohorts. In predicting OS, SELECTION-TC and SELECTION-HC demonstrated AUCs of 0.736 (95% CI, 0.608-0.841) and 0.748 (95% CI, 0.599-0.865) respectively, in their external validation sets. SELECTION-derived survival scores effectively stratified patients into high and low-risk groups, showing significant differences in survival probabilities (P<0.05 across all four cohorts). Additionally, the concordance between ATOM and clinician recommendations was associated with significantly higher response/survival rates in cases of agreement, particularly within the TACE, HAIC, and TC cohorts in the external validation sets (P<0.05). ATOM was proposed based on SELECTION-derived survival scores, emerges as a promising tool to inform the selection among different intra-arterial interventional therapy techniques.

Hepatic Arterial Infusion Chemotherapy Combined Lenvatinib and PD-1 Inhibitor Showed Improved Survival for Infiltrative Hepatocellular Carcinoma: A Multicenter Cohort Study.

Lenvatinib and programmed cell death protein-1 (PD-1) inhibitor on infiltrative hepatocellular carcinoma (HCC) have obtained demonstrated efficacy and still need improvement. Hepatic arterial infusion chemotherapy (HAIC) has shown promising results for advanced HCC. This study aimed to compare the efficacy of HAIC combined Lenvatinib and PD-1 inhibitor versus Lenvatinib combined PD-1 inhibitor for infiltrative HCC. A total of 232 patients were enrolled. There were 114 patients received Lenvatinib combined PD-1 inhibitor (Len+PD-1 group) and 118 patients received HAIC combined Lenvatinib and PD-1 inhibitor (HAIC+Len+PD-1 group). Overall survival (OS), progression-free survival (PFS) and safety of patients were compared between the two groups by propensity score-matching (PSM). The 6-, 12-, and 24-month OS rates were 93.8%, 65.1% and 13.4% in Len+PD-1 group, and 100%, 77.3% and 32.1% in HAIC+Len+PD-1 group, respectively. The 3-, 6-, and 12-month PFS rates were 86.4%, 45.7% and 14.1% in Len+PD-1 group, and 95.1%, 59.3% and 25.9% in HAIC+Len+PD-1 group, respectively. The HAIC+Len+PD-1 group had obviously better survival than the Len+PD-1 group both in OS (P=0.002) and PFS (P=0.004). Subgroup analysis revealed that OS in patients with metastasis was improved with HAIC+Len+PD-1 treatment. Patients with alpha-fetoprotein (AFP) response after treatment showed better survival than the non-response. In addition, HAIC+Len+PD-1 group showed manageable adverse events (AEs). Patient with infiltrative HCC, HAIC+Len+PD-1 treatment had longer OS and PFS than Len+PD-1 treatment. Early AFP response was an effective indicator of better survival and tumor response to therapy.

Efficacy and safety of hepatic arterial infusion chemotherapy combined with donafenib in the treatment of unresectable hepatocellular carcinoma.

This study aimed at ascertaining the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) combined with donafenib versus HAIC alone in the treatment of unresectable hepatocellular carcinoma (HCC). Seventy HCC patients were enrolled for our study, and they were randomized by simple randomization using computer-generated random numbers into two groups: control group and observation group. Regular follow-up reviews were conducted to assess the efficacy of treatments. The levels of apoptotic factors, the levels of hepatic fibrosis indices, the levels of serum tumor vascular factors and tumor markers, and the occurrence of adverse reactions in the two groups were recorded and compared. Disease control rate, objective response rate, and progression-free survival (PFS) of patients in the observation group were higher in contrast to the control group. After 12 weeks of treatment, lower mRNA expression of c-mesenchymal-epithelial transition factor, telomerase, and Fas Ligand and higher mRNA expression of Fas and Caspase-3 were observed in HCC tissues of the observation group versus the control group (p<0.05); lower detection values of serum laminin, hyaluronic acid, collage type IV, vascular endothelial growth factor receptor 2, and alpha-fetal protein (AFP) were noted in HCC patients of the observation group in comparison to the control group (p<0.05); there was no difference in the incidence of adverse reactions between the two groups. Donafenib combined with HAIC in the treatment of unresectable HCC patients can notably reduce serum AFP levels, improve hepatic fibrosis, enhance short-term efficacy, prolong PFS, and have a favorable safety profile.

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.

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

Efficacy of hepatic arterial infusion chemotherapy and its combination strategies for advanced hepatocellular carcinoma: A network meta-analysis

BACKGROUND With the rapid progress of systematic therapy for hepatocellular carcinoma (HCC), therapeutic strategies combining hepatic arterial infusion chemotherapy (HAIC) with systematic therapy arised increasing concentrations. However, there have been no systematic review comparing HAIC and its combination strategies in the first-line treatment for advanced HCC. AIM To investigate the efficacy and safety of HAIC and its combination therapies for advanced HCC. METHODS A network meta-analysis was performed by including 9 randomized controlled trails and 35 cohort studies to carry out our study. The outcomes of interest comprised overall survival (OS), progression-free survival (PFS), tumor response and adverse events. Hazard ratios (HR) and odds ratios (OR) with a 95% confidence interval (CI) were calculated and agents were ranked based on their ranking probability. RESULTS HAIC outperformed Sorafenib (HR = 0.55, 95%CI: 0.42-0.72; HR = 0.51, 95%CI: 0.33-0.78; OR = 2.86, 95%CI: 1.37-5.98; OR = 5.45, 95%CI: 3.57-8.30; OR = 7.15, 95%CI: 4.06-12.58; OR = 2.89, 95%CI: 1.99-4.19; OR = 0.48, 95%CI: 0.25-0.92, respectively) and transarterial chemoembolization (TACE) (HR = 0.50, 95%CI: 0.33-0.75; HR = 0.62, 95%CI: 0.39-0.98; OR = 3.08, 95%CI: 1.36-6.98; OR = 2.07, 95%CI: 1.54-2.80; OR = 3.16, 95%CI: 1.71-5.85; OR = 2.67, 95%CI: 1.59-4.50; OR = 0.16, 95%CI: 0.05-0.54, respectively) in terms of efficacy and safety. HAIC + lenvatinib + ablation, HAIC + ablation, HAIC + anti- programmed cell death 1 (PD-1), and HAIC + radiotherapy had the higher likelihood of providing better OS and PFS outcomes compared to HAIC alone. HAIC + TACE + S-1, HAIC + lenvatinib, HAIC + PD-1, HAIC + TACE, and HAIC + sorafenib had the higher likelihood of providing better partial response and objective response rate outcomes compared to HAIC. HAIC + PD-1, HAIC + TACE + S-1 and HAIC + TACE had the higher likelihood of providing better complete response and disease control rate outcomes compared to HAIC alone. CONCLUSION HAIC proved more effective and safer than sorafenib and TACE. Furthermore, combined with other interventions, HAIC showed improved efficacy over HAIC monotherapy according to the treatment ranking analysis.

Camrelizumab, apatinib and hepatic artery infusion chemotherapy combined with microwave ablation for advanced hepatocellular carcinoma.

Hepatic arterial infusion chemotherapy and camrelizumab plus apatinib (TRIPLET protocol) is promising for advanced hepatocellular carcinoma (Ad-HCC). However, the usefulness of microwave ablation (MWA) after TRIPLET is still controversial. To compare the efficacy and safety of TRIPLET alone (T-A) vs TRIPLET-MWA (T-M) for Ad-HCC. From January 2018 to March 2022, 217 Ad-HCC patients were retrospectively enrolled. Among them, 122 were included in the T-A group, and 95 were included in the T-M group. A propensity score matching (PSM) was applied to balance bias. Overall survival (OS) was compared using the Kaplan-Meier curve with the log-rank test. The overall objective response rate (ORR) and major complications were also assessed. After PSM, 82 patients were included both the T-A group and the T-M group. The ORR (85.4%) in the T-M group was significantly higher than that (65.9%) in the T-A group (P < 0.001). The cumulative 1-, 2-, and 3-year OS rates were 98.7%, 93.4%, and 82.0% in the T-M group and 85.1%, 63.1%, and 55.0% in the T-A group (hazard ratio = 0.22; 95% confidence interval: 0.10-0.49; P < 0.001). The incidence of major complications was 4.9% (6/122) in the T-A group and 5.3% (5/95) in the T-M group, which were not significantly different (P = 1.000). T-M can provide better survival outcomes and comparable safety for Ad-HCC than T-A.
