The efficacy of hepatic arterial infusion chemotherapy as an alternative to sorafenib in advanced hepatocellular carcinoma

Aims: Sorafenib is the only systemic treatment shown to be effective against advanced hepatocellular carcinoma (HCC). Hepatic arterial infusion chemotherapy (HAIC) has been selected as an alternative therapeutic option for advanced HCC. We investigated the efficacy and safety of HAIC as an alternative treatment for sorafenib in advanced HCC. Methods: Between May 2008 and March 2011, 20 consecutive patients were treated with sorafenib monotherapy as a first‐line treatment and 21 consecutive patients who could not take sorafenib because of cost were treated with HAIC monotherapy as an alternative. Sorafenib was administered in 400 mg b.i.d. doses. For HAIC, daily cisplatin (7 mg/m² on days 1–5) and 5‐FU (170 mg/m² on days 1–5) were infused every 4 weeks. We assessed overall survival (OS), progression‐free survival (PFS), objective response rate (ORR) and toxicity. Results: Median OS was 4.9 months (95% CI, 3.4–6.4) for sorafenib and 7.3 months (95% CI, 4.5–10.2) for HAIC (P = 0.599). Median PFS was 2.0 months (95% CI, 1.96–2.05) versus 3.0 months (95% CI, 1.98–4.02) for sorafenib and HAIC, respectively (P = 0.303). ORR and disease control rate (DCR) for sorafenib were 10.0 and 35.0% versus 19.0 and 38.1% for HAIC (ORR, P = 0.413; DCR, P = 0.837). Patients treated with HAIC more frequently exhibited grade 3/4 neutropenia (23.8 vs 0% for sorafenib), whereas sorafenib therapy showed grade 3/4 hand‐foot skin reaction in 10% of patients. Conclusion: HAIC is a useful alternative treatment for advanced HCC and further prospective investigations are required.     

Hepatic arterial infusion chemotherapy (HAIC)--hepatocellular carcinoma

Hepatic arterial infusion chemotherapy (HAIC) has been often selected as a therapeutic option for advanced hepatocellular carcinoma (HCC) with intrahepatic metastases or portal vein thrombosis, which is not eligible for hepatic resection, tumor ablation, or embolization. Among various regimens, HAIC, consisting of 5-fluorouracil (5-FU) in combination with either low-doses of cisplatin (CDDP) or interferon-alpha has been reported to improve the response rates for advanced HCC. As both regimens require the use of an implanted port-catheter system, maintaining the patency of hepatic arteries is an important factor for the intrahepatic drug distribution and the efficacy of HAIC. Recently, a new product, CDDP powder has been also developed for intraarterial use, which adds a new option to HAIC. However, the long-term outcome or the survival benefit remains unclear with HAIC, and it may be significantly affected by liver function and cirrhosis. None of the regimens have been proved to be the standard for HAIC, and prospective multi-center clinical studies with standardized protocol are needed in the future.     

Pilot clinical trial of localized concurrent chemoradiation therapy for locally advanced hepatocellular carcinoma with portal vein thrombosis

BACKGROUND: Patients with advanced hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) have a particularly grave prognosis. In the current study, an attempt was made to localize chemoradiation therapy (CCRT) followed by hepatic arterial infusion chemotherapy (HAIC) in patients with locally advanced HCC with PVT and good reserve liver function. The objective of the current study was to evaluate the therapeutic effect of localized CCRT followed by HAIC as a new treatment modality for these patients. METHODS: Between January 1998 and December 2003, 40 patients were recruited. Concurrent regional chemotherapy using an intra-arterial implanted port plus localized external beam radiotherapy was performed with a total of 45 gray (Gy) over 5 weeks with conventional fractionation and hepatic arterial infusion of 5-fluorouracil (5-FU), which was administered during the first and fifth weeks of radiotherapy. One month after localized CCRT, HAIC with 5-FU and cisplatin was administered every 4 weeks. RESULTS: One month after localized CCRT, an objective response was observed on the intention-to-treat analysis in 18 of 40 patients (45%). The actuarial 3-year overall survival rate was 24.1% and the median survival time was 13.1 months from the start of radiation treatment. Responders after localized CCRT demonstrated significantly better survival (P = .033) than nonresponders. CONCLUSIONS: The substantial response rate as well as median survival time noted in the current study encourages the use of this new approach in patients with locally advanced HCC with PVT.     

Hepatic arterial infusion chemotherapy for advanced hepatocellular carcinoma with portal vein tumor thrombosis: analysis of 48 cases

BACKGROUND: The prognosis of patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is extremely poor. The aim of this study was to elucidate the efficacy of hepatic arterial infusion chemotherapy (HAIC) for patients with advanced HCCs. METHODS: Forty-eight HCC patients with PVTT were treated by HAIC via a subcutaneously implanted injection port. Of these, 14 had PVTT in the second portal branch and 34 patients had PVTT in the first portal branch or in the main portal trunk. One course of chemotherapy consisted of daily cisplatin (7 mg/m(2) for 1 hour on Days 1-5) followed by 5-fluorouracil (170 mg/m(2) for 5 hours on Days 1-5). Patients were scheduled to receive four serial courses of HAIC. Responders were defined as having either a complete response (CR) or partial response (PR) and nonresponders were defined as exhibiting stable disease or progressive disease. The prognosis after HAIC and factors related to survival were analyzed. RESULTS: Following HAIC, 4 and 19 patients exhibited a CR and PR, respectively (response rate = 48%). The 1, 2, 3, and 5-year cumulative survival rates of 48 patients treated with HAIC were 45%, 31%, 25%, and 11%, respectively. Median survival periods for 23 responders and 25 nonresponders were 31.6 (range, 8.3-76.9) months and 5.4 (1.9-29.0) months, respectively. Therapeutic effect (P < 0.001) and hepatic reserve capacity (P = 0.021) were identified as significant prognostic factors by univariate analysis. Multivariate analysis identified only therapeutic effect as being significantly related to survival. CONCLUSIONS: HAIC using low-dose cisplatin and 5-fluorouracil may be a useful therapeutic option for patients with advanced HCC with PVTT. HCC patients with PVTT who respond to HAIC could certainly have survival benefits.     

Repetitive short-course hepatic arterial infusion chemotherapy with high-dose 5-fluorouracil and cisplatin in patients with advanced hepatocellular carcinoma

BACKGROUND: Hepatic arterial infusion chemotherapy (HAIC) has often been selected as a therapeutic option for patients with advanced hepatocellular carcinoma (HCC). The objective of the current study was to evaluate the efficacy and safety of repetitive HAIC with high-dose 5-fluorouracil (5-FU) and cisplatin given for 3 days in patients with advanced HCC. METHODS: Between January 2001 and December 2004, a total of 41 patients with unresectable advanced HCC were enrolled. The patients underwent HAIC via the implantable port system with 5-FU (at a dose of 500 mg/m(2) on Days 1-3) and cisplatin (at a dose of 60 mg/m(2) on Day 2) every 4 weeks. Tumor response was assessed at the end of every 3 cycles. RESULTS: The median age of the patients was 53 years and 34 patients (82.9%) had evidence of portal vein thrombosis. In total, 230 cycles of HAIC were administered to the 41 patients, with a median of 6 cycles given (range, 1-14 cycles). Nine patients (22.0%) achieved a partial response and 14 patients (34.1%) had stable disease. The median time to disease progression and overall survival were 7.0 months and 12.0 months, respectively. The overall survival was found to be significantly longer in the successful disease control group (patients with a complete response, partial response, and stable disease) than in the disease progression group (median of 14.0 months vs 6.0 months; P < .001). Adverse reactions were tolerable and successfully managed with conservative treatment. CONCLUSIONS: HAIC with high-dose 5-FU and cisplatin given for 3 days achieved effective and safe results in patients with advanced HCC. Therefore, repetitive short-course HAIC with high-dose 5-FU and cisplatin may be useful as an alternative therapeutic option for patients with advanced HCC.     

Successful treatment for advanced hepatocellular carcinoma by hepatic arterial infusion of CDDP powder as second-line chemotherapy

A 72-year-old man with type C liver cirrhosis had suffered from hepatocellular carcinoma (HCC) since April, 2001. HCC spread diffusely all over the right lobe of his liver, and the serum alpha-fetoprotein (AFP) value increased up to 42,696 ng/ml in June of 2004. He was implanted with a port-catheter system, and hepatic arterial infusion chemotherapy (HAIC) using low-dose of CDDP and 5-FU was started. However, it was not effective and after 4 months, the serum AFP level increased up to 755,030 ng/ml, ascites appeared, and gastro-esophageal varices also spread. No definite metastasis was detected, then we started to second-line chemotherapy. He was then given HAIC using CDDP powder for intraarterial use (CDDP 50 mg/m(2)/20 min, monthly). After 3 courses, the serum AFP level decreased to 9 10 ng/ml, and abdominal CT revealed that the main tumor had regressed and ascites had disappeared. After one more course, the serum AFP value decreased to 8 ng/ml and complete response was achieved on abdominal CT imaging. There was no major complication related to the chemotherapy. HAIC for advanced HCC using LFP has been reported to achieve favorable results, but no other regimens have been proved to the standard for HCC. HAIC using CDDP powder for advanced HCC may be beneficial as the second-line chemotherapy.     

Efficacy and safety of sorafenib plus hepatic arterial infusion chemotherapy for advanced hepatocellular carcinoma

BackgroundSorafenib is the standard treatment for patients with advanced HCC with improvement in survival and radiologic progression of the disease. Recently, few studies have advocated the Sorafenib + HAIC combination therapy results in better overall survival and progression-free survival than Sorafenib monotherapy in patients with advanced HCC. Herein, we aim to identify the best possible treatment option among the above two lines of therapy for patients with advanced HCC.MethodsThe fixed effects and a random-effects model were used to perform a meta-analysis for overall response rate overall survival, and adverse events. Subgroup analysis of the data of univariate analysis in each included trial was performed to identify the specific patient population who could be benefitted from the combination therapy.ResultsFour RCTs containing 609 patients were included in the final analysis. The overall response rate (OR: 3.81; 95% CI 1.01 to 14.42; P = 0.05) and overall survival (HR: 0.70; 95% CI 0.40 to 1.24; P > 0.05) were comparable. Subgroup analysis of OS showed that patients with Child-Pugh score B (HR: 0.30; 95% CI 0.13 to 0.72; P < 0.05) and AFP <400 ng/ml (HR: 0.72; 95% CI 0.52 to 0.99; P < 0.05) were associated with significantly improved survival in the Sorafenib + HAIC group. Bone marrow suppression (OR: 3.76; 95% CI 2.58 to 5.48; P < 0.001) was significantly higher in the Sorafenib + HAIC group, but hepatic function impairment, constitutional symptoms, gastrointestinal events, and dermatological events were comparable (p > 0.05).ConclusionsPatients with Child-Pugh score B and AFP <400 ng/ml may be benefited most from Sorafenib + HAIC combination therapy.     

Targeting the microRNA-21/AP1 axis by 5-fluorouracil and pirarubicin in human hepatocellular carcinoma

MicroRNAs function as oncomiRs and tumor suppressors in diverse cancers. However, the utility of specific microRNAs in predicting the clinical benefit of chemotherapy has not been well-established. Here, we investigated the correlation between microRNA-21 expression and hepatic arterial infusion chemotherapy with 5-fluorouracil and pirarubicin (HAIC) for hepatocellular carcinoma (HCC). We found that HCC patients with low microRNA-21 levels in tumors tended to have a longer time to recurrence and disease-free survival. We demonstrated that microRNA-21 suppression in combination with 5-fluorouracil and pirarubicin treatment inhibited tumor growth in subcutaneous xenograft mice models. Mechanistically, the AP-1 and microRNA-21-mediated axis was verified to be a therapeutic target of cytotoxic drugs and deregulation of this axis led to an enhanced cell growth in HCC. Taken together, our findings demonstrate that microRNA-21 is a chemotherapy responsive microRNA and can serve as a prognostic biomarker for HCC patients undergoing HAIC. Targeting microRNA-21 enhances the effect of chemotherapeutic drugs, thereby suggesting that microRNA-21 suppression in combination with HAIC may be a novel approach for HCC treatment.     

Hepatic artery infusion chemotherapy using mFOLFOX versus transarterial chemoembolization for massive unresectable hepatocellular carcinoma:a prospective non-randomized study

Background: Transarterial chemoembolization (TACE) is recommended as the standard care for unresectable hepa-tocellular carcinoma (HCC) at Barcelona Clinic Liver Cancer (BCLC) stage A–B. However, the efficacy of TACE on large (≥ 10 cm) stage A–B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy (HAIC) might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX (mFOLFOX) regimen and those of TACE in patients with massive unresectable HCC. Methods: A prospective, non-randomized, phase Ⅱ study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen (oxaliplatin, 85 mg/m2intra-arterial infusion; leucovorin, 400 mg/m2intra-arterial infusion; and fluorouracil, 400 mg/m2bolus infusion and 2400 mg/m2continuous infusion) every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression (TTP), and safety were assessed. Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group (52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months (hazard radio [HR] = 2.35, 95% confidence interval [CI] = 1.16–4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection (10 vs. 3, P = 0.033). The proportions of grade 3–4 adverse events (AE) and serious adverse events (SAE) were lower in the HAIC group than in the TACE group (grade 3–4 AEs: 13 vs. 27, P = 0.007; SAEs: 6 vs. 15, P = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent (10 vs. 2, P = 0.026). Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.

Different interventional time of hepatic arterial infusion with PD-1 inhibitor for advanced biliary tract cancer: a multicenter retrospective study

This study investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) combined with PD-1 immunotherapy for advanced biliary tract cancer (BTC) and evaluated the optimal timing of HAIC. A total of 36 unresectable BTC patients treated with HAIC and PD-1 inhibitors between September 2019 and July 2021 were included in this study. Overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs) were investigated. Overall, 52.8% patients with advanced BTC were in stage IV, 23 patients who progressed after receiving PD-1 inhibitor had undergone HAIC, and 23 patients have received 2 or more lines of therapy. The median OS was 8.8 months (range: 4.0-24.0 months), and the median PFS was 3.7 months. The objective response rate and disease control rate were 11.5% and 76.9%, respectively. In the subgroup analysis, patients who treated with HAIC early without progression after immunotherapy were associated with a trend toward better OS (median 13.0 vs. 7.6 months; P = 0.004) and PFS (median 7.9 vs. 3.6 months; P = 0.09) compared to with HAIC with progression after PD-1 treatment. No treatment-related deaths occurred. A total of 44.4% of the patients experienced grade 3 or 4 AEs. We conclude that the combination of HAIC and PD-1 inhibitors is safe and effective. Early HAIC combined with immunotherapy can effectively prolong the overall survival of patients with advanced BTC.     

A randomized comparative study of high-dose and low-dose hepatic arterial infusion chemotherapy for intractable, advanced hepatocellular carcinoma

Purpose

Hepatic arterial infusion chemotherapy (HAIC) has been reported to be effective in patients with advanced hepatocellular carcinoma (HCC).

Methods

In this multicenter, prospective, open-labeled, clinical trial, we randomly assigned 68 patients with advanced HCC to receive either low-dose [n = 32, 5-fluorouracil (FU), 170 mg/m² and cisplatin, 7 mg/m² on days 1–5] or high-dose HAIC (n = 36, 5-FU, 500 mg/m² on days 1–3 and cisplatin, 60 mg/m² on day 2) every 4 weeks via an implantable port system.

Results

A total of 207 cycles of HAIC was given to the 68 patients. Overall, 6 patients (8.8%) achieved a partial response and 21 patients (30.9%) had stable disease. The objective response rate (CR + PR) was significantly improved in the high-dose group compared to the low-dose group (16.7% vs. 0%, P = 0.024). The median time to disease progression and overall survival were slightly prolonged in the high-dose group compared to the low-dose group (median survival, 193 vs. 153 days; P = 0.108; median time to disease progression, 145 vs. 90 days; P = 0.095). Multivariate analysis showed that tumor response to treatment [P = 0.007, RR 2.27 (95% CI, 1.248–4.132)] was the only factor associated with overall survival. All adverse events were tolerable and successfully managed in both treatment groups.

Conclusions

Both HAIC regimens are safe and effective in patients with advanced HCC. High-dose HAIC achieves a better tumor response compared to low-dose HAIC.     

Response to chemotherapy improves hepatic reserve for patients with hepatocellular carcinoma and Child–Pugh B cirrhosis

There is no established treatment for patients with advanced hepatocellular carcinoma (HCC) with Child–Pugh class B cirrhosis. The aim of the present study was to assess the efficacy of hepatic arterial infusion chemotherapy (HAIC) according to Child–Pugh score (CPS) and to evaluate the correlation of a patient's response to HAIC with hepatic reserve and outcome. We retrospectively reviewed the medical records of 377 patients treated with HAIC between March 2003 and February 2015. Subjects included 179 with Child–Pugh class B. Median overall survival was 12.1 months for patients with CPS = 7 (n = 75) and 11.9 months for patients with CPS = 8 (n = 58), which were significantly longer compared with those of patients with CPS = 9 (n = 46, 6.3 months). The objective response rates of patients with CPS = 7, 8 and 9 were 26.7%, 27.6% and 6.5%, respectively. The CPS of responders improved significantly after HAIC, whereas those of nonresponders did not. A multivariate analysis demonstrated that improved CPS, responses to HAIC and absence of extrahepatic lesions were independent favorable prognostic factors. Patients with CPS = 7 or 8 tolerated HAIC, but nine (19.6%) of patients with CPS = 9 were unable to complete one course. HAIC is effective and safe for patients with a CPS = 7 or 8 and improved hepatic reserve of responders significantly.     

Effect of hepatic arterial infusion chemotherapy of 5-fluorouracil and cisplatin for advanced hepatocellular carcinoma in the Nationwide Survey of Primary Liver Cancer in Japan

Background:

The efficacy of hepatic arterial infusion chemotherapy for the treatment of advanced hepatocellular carcinoma (HCC) remains unclear.

Methods:

The outcome of 476 patients with HCC who underwent hepatic arterial infusion chemotherapy with 5-fluorouracil and cisplatin (HAIC) were compared with 1466 patients who did not receive active therapy.

Results:

A survival benefit of the therapy after adjusting for known risk factors was observed (hazard ratio, 0.48; 95% CI, 0.41–0.56; P<0.0001). In propensity score-matched analysis (n=682), median survival time was longer for patients who underwent chemotherapy (14.0 months) than for patients who did not receive active treatment (5.2 months, P<0.0001).

Conclusion:

For advanced HCC, HAIC is considered to be an effective treatment.     

High expression of CD44v9 and xCT in chemoresistant hepatocellular carcinoma: Potential targets by sulfasalazine

CD44v9 is expressed in cancer stem cells (CSC) and stabilizes the glutamate‐cystine transporter xCT on the cytoplasmic membrane, thereby decreasing intracellular levels of reactive oxygen species (ROS). This mechanism confers ROS resistance to CSC and CD44v9‐expressing cancer cells. The aims of the present study were to assess: (i) expression status of CD44v9 and xCT in hepatocellular carcinoma (HCC) tissues, including those derived from patients treated with hepatic arterial infusion chemoembolization (HAIC) therapy with cisplatin (CDDP); and (ii) whether combination of CDDP with sulfasalazine (SASP), an inhibitor of xCT, was more effective on tumor cells than CDDP alone by inducing ROS‐mediated apoptosis. Twenty non‐pretreated HCC tissues and 7 HCC tissues administered HAIC therapy with CDDP before surgical resection were subjected to immunohistochemistry analysis of CD44v9 and xCT expression. Human HCC cell lines HAK‐1A and HAK‐1B were used in this study; the latter was also used for xenograft experiments in nude mice to assess in vivo efficacy of combination treatment. CD44v9 positivity was significantly higher in HAIC‐treated tissues (5/7) than in non‐pretreated tissues (2/30), suggesting the involvement of CD44v9 in the resistance to HAIC. xCT was significantly expressed in poorly differentiated HCC tissues. Combination treatment effectively killed the CD44v9‐harboring HAK‐1B cells through ROS‐mediated apoptosis and significantly decreased xenografted tumor growth. In conclusion, the xCT inhibitor SASP augmented ROS‐mediated apoptosis in CDDP‐treated HCC cells, in which the CD44v9‐xCT system functioned. As CD44v9 is typically expressed in HAIC‐resistant HCC cells, combination treatment with SASP with CDDP may overcome such drug resistance.     

甲胎蛋白对索拉菲尼治疗进展期肝细胞癌的预后评价

Hepatic arterial infusion chemotherapy for liver metastases from colorectal cancer

After randomized studies of hepatic arterial infusion chemotherapy (HAIC) versus systemic chemotherapy for liver metastases from colorectal cancer in the 1980s, the role of HAIC has been unclear and there is still no evidence to support it as the treatment of choice. The high local control, the differences in techniques between Japan and Western countries, the difficulty of detecting pre-treatment extra-hepatic metastases and the fact that HAIC does not control extra-hepatic lesions are the most important points in considering clinical trials of HAIC. Clinical studies on the combination of HAIC using 5-FU and systemic chemotherapy using CPT-11, and then randomized trial of systemic chemotherapy with/without HAIC is required in Japan to reveal the role of HAIC in the management of liver metastases from colorectal cancer. We should understand the importance of our role in this field.     

A multi-institutional phase II trial of hepatic arterial infusion chemotherapy with cisplatin for advanced hepatocellular carcinoma with portal vein tumor thrombosis

Purpose

The objective of this study was to evaluate the response rate, survival, and adverse effects of hepatic arterial infusion chemotherapy (HAIC) using cisplatin in patients with advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT).

Methods

Twenty-five patients of advanced HCC with PVTT in the main or first branch, having no prior history of chemotherapy, measurable lesions, adequate liver and renal function, and adequate bone marrow reserve, were enrolled. Cisplatin was administered at the dose of 65 mg/m² via the proper hepatic artery. Treatment was repeated every 4–6 weeks for a maximum of six courses until the appearance of evidence of tumor progression or unacceptable toxicity.

Results

The median number of treatments was 3 (range 1–6). Among the 25 enrolled patients, complete response was achieved in 1 (4 %) patient and partial response in 6 (24 %), corresponding to a response rate of 28 % (95 % CI 12–49 %). The median progression-free and overall survival times and the 1-, 2-, and 3-year survival rates in the enrolled patients were 3.6 and 7.6 months and 40.3, 36.0, 20 %, respectively. Four of the seven patients who showed complete or partial response survived for more than 3 years. The main grade 3/4 non-hematological adverse events of this treatment were elevation of the serum aspartate aminotransferase (44 %) and alanine aminotransferase (24 %).

Conclusion

HAIC with cisplatin exerts moderate activity with mild toxicity in advanced HCC patients with PVTT. Especially, markedly prolonged survival can be expected in patients who respond to this treatment.     

Hepatic arterial infusion of chemotherapy: the role of diagnostic and interventional radiology.

Hepatic arterial infusion of chemotherapy (HAIC) delivers higher local drug concentration to unresectable liver tumors with fewer significant systemic side-effects. It has been shown to produce better response rates than systemic chemotherapy and remains an important treatment option in patients with advanced, inoperable primary or metastatic hepatic tumors. Traditionally, catheters for HAIC were inserted surgically under general anesthesia. The advancement and expansion of interventional radiology have made it possible for catheter-port systems to be inserted percutaneously under local anesthesia with no significant increase in morbidity. A comprehensive review of the literature, techniques and complications of percutaneous placement of catheter-port systems for HAIC is presented in this article.     

Hepatocellular carcinoma: resection with adjuvant hepatic artery infusion therapy vs resection alone. A systematic review and meta-analysis

Hepatocellular carcinoma (HCC) has a recurrence rate of up to 70% in 5 years after resection, detrimentally lowering survival. The role of adjuvant therapy remains controversial; therefore, the aim of this study was to evaluate the disease-free and overall survival of patients with HCC, not candidates for transplantation, undergoing resection and adjuvant hepatic artery infusion therapy vs resection alone. Our meta-analysis showed that adjuvant HAIC improves overall and disease-free survival after resection, especially in tumors ≥7 cm.
